Indoor environmental quality benefits of apartment energy retrofits Indoor environmental quality benefits of apartment energy retrofits Title Indoor environmental quality benefits of apartment energy retrofits Publication Type Journal Article LBNL Report Number LBNL-6373E Year of Publication 2013 Authors Noris, Federico, Gary Adamkiewicz, William W. Delp, Toshifumi Hotchi, Marion L. Russell, Brett C. Singer, Michael Spears, Kimberly Vermeer, and William J. Fisk Journal Building Environment Volume 68 Pagination 170-178 Date Published 10/2013 Keywords Apartments; Energy; Indoor environmental quality; Retrofit; Selection Abstract Sixteen apartments serving low-income populations in three buildings were retrofit with the goal of simultaneously reducing energy consumption and improving indoor environmental quality (IEQ). Retrofit measures varied among apartments and included, among others, envelope sealing, installation of continuous mechanical ventilation systems, upgrading bathroom fans and range hoods, attic insulation, replacement of heating and cooling systems, and adding wall-mounted particle air cleaners. IEQ parameters were measured, generally for two one-week periods before and after the retrofits. The measurements indicate an overall improvement in IEQ conditions after the retrofits. Comfort conditions, bathroom humidity, and concentrations of carbon dioxide, acetaldehyde, volatile organic compounds, and particles generally improved. Formaldehyde and nitrogen dioxide levels decreased in the building with the highest concentrations, were unchanged in a second building, and increased in a third building. IEQ parameters other than particles improved more in apartments with continuous mechanical ventilation systems installed. In general, but not consistently, larger percent increases in air exchange rates were associated with larger percent decreases in indoor levels of the pollutants that primarily come from indoor sources.

Impact evaluation of the energy retrofits installed in the Margolis high-rise apartment building, Chelsea housing authority  

SciTech Connect

As part of a joint demonstration effort involving HUD, DOE, a local public housing authority and Boston Edison, an evaluation of energy and demand saving retrofits was conducted for a tall, residential, low-income building located in Boston. The thirteen story building underwent window, lighting, and heating system control renovations in December, 1992. The success of these retrofits was determined using monthly and hourly whole-building consumption data along with a calibrated DOE-2.1D energy simulation model. According to the model developed, post-retrofit conditions showed reductions in annual energy consumption of 325 MWh and in peak demand of 100 kW. These savings resulted in an annual energy cost savings of $28,000. Over 90% of energy and cost savings were attributed to the window retrofit. Interaction of the reduction in lighting capacity with the building`s electric resistance heating system reduced the potential for energy and demand savings associated with the lighting retrofit. Results from the hourly simulation model also indicate that night setbacks controlled by the energy management system were not implemented. An additional 32 MWh in energy savings could be obtained by bringing this system on-line, however peak demand would be increased by 40 kW as the morning demand for space heat is increased, with a net loss in cost savings of $2,500.

Advancing Residential Energy Retrofits  

Science Conference Proceedings (OSTI)

To advance the market penetration of residential retrofits, Oak Ridge National Laboratory (ORNL) and Southface Energy Institute (Southface) partnered to provide technical assistance on nine home energy retrofits in metropolitan Atlanta with simulated source energy savings of 30% to 50%. Retrofit measures included duct sealing, air infiltration reductions, attic sealing and roofline insulation, crawlspace sealing, HVAC and water heating equipment replacement, and lighting and appliance upgrades. This paper will present a summary of these measures and their associated impacts on important home performance metrics, such as air infiltration and duct leakage. The average estimated source energy savings for the homes is 33%, and the actual heating season average savings is 32%. Additionally, a case study describing expected and realized energy savings of completed retrofit measures of one of the homes is described in this paper.

Retrofitting for Energy Savings  

E-Print Network (OSTI)

Energy audits provide a measure of current energy usage and indicate areas where energy usage can be reduced from present levels. The next step is to make an in-depth process engineering review lo quantify what modifications can be made to a plant, what energy savings will result and what capital costs are needed for particular modifications that must be made. Economic considerations, together with space availability for new equipment, determine what can be done in an existing plant to economically reduce energy usage.

Building Energy Model Development for Retrofit Homes  

SciTech Connect

Based on previous research conducted by Pacific Northwest National Laboratory and Florida Solar Energy Center providing technical assistance to implement 22 deep energy retrofits across the nation, 6 homes were selected in Florida and Texas for detailed post-retrofit energy modeling to assess realized energy savings (Chandra et al, 2012). However, assessing realized savings can be difficult for some homes where pre-retrofit occupancy and energy performance are unknown. Initially, savings had been estimated using a HERS Index comparison for these homes. However, this does not account for confounding factors such as occupancy and weather. This research addresses a method to more reliably assess energy savings achieved in deep energy retrofits for which pre-retrofit utility bills or occupancy information in not available. A metered home, Riverdale, was selected as a test case for development of a modeling procedure to account occupancy and weather factors, potentially creating more accurate estimates of energy savings. This true up procedure was developed using Energy Gauge USA software and post-retrofit homeowner information and utility bills. The 12 step process adjusts the post-retrofit modeling results to correlate with post-retrofit utility bills and known occupancy information. The trued post retrofit model is then used to estimate pre-retrofit energy consumption by changing the building efficiency characteristics to reflect the pre-retrofit condition, but keeping all weather and occupancy-related factors the same. This creates a pre-retrofit model that is more comparable to the post-retrofit energy use profile and can improve energy savings estimates. For this test case, a home for which pre- and post- retrofit utility bills were available was selected for comparison and assessment of the accuracy of the true up procedure. Based on the current method, this procedure is quite time intensive. However, streamlined processing spreadsheets or incorporation into existing software tools would improve the efficiency of the process. Retrofit activity appears to be gaining market share, and this would be a potentially valuable capability with relevance to marketing, program management, and retrofit success metrics.

Through discussion of five case studies (test homes), this project evaluates strategies to elevate the performance of existing homes to a level commensurate with best-in-class implementation of high-performance new construction homes. The test homes featured in this research activity participated in Deep Energy Retrofit (DER) Pilot Program sponsored by the electric and gas utility National Grid in Massachusetts and Rhode Island. Building enclosure retrofit strategies are evaluated for impact on durability and indoor air quality in addition to energy performance. Evaluation of strategies is structured around the critical control functions of water, airflow, vapor flow, and thermal control. The aim of the research project is to develop guidance that could serve as a foundation for wider adoption of high performance, 'deep' retrofit work. The project will identify risk factors endemic to advanced retrofit in the context of the general building type, configuration and vintage encountered in the National Grid DER Pilot. Results for the test homes are based on observation and performance testing of recently completed projects. Additional observation would be needed to fully gauge long-term energy performance, durability, and occupant comfort.

A Methodology to Measure Retrofit Energy Savings in Commercial Buildings  

E-Print Network (OSTI)

Measured energy savings promote and sustain energy conservation retrofits by verifying the success of retrofits, determining pay-back schedules, guiding the selection of future retrofits and identifying opportunities for further savings. This dissertation develops a methodology to measure retrofit energy savings and the uncertainty of the savings in commercial buildings. The functional forms of empirical models of cooling and heating energy use in commercial buildings are derived from an engineering analysis of constant-air-volume and variable-air-volume HVAC systems. One, two, three and four parameter, temperature-dependent regression models are proposed to model baseline energy use. Retrofit savings are measured as the difference between the baseline energy use project by the models and the measured post-retrofit energy use. A hybrid ordinary least squares/autoregressive method is developed to determine the uncertainty of the predicated energy use and savings. The annual predictive ability of models based on pre-retrofit data sets of less than a full year is investigated. The energy delivery efficiency is introduced to measure the efficiency of air-side systems at meeting the net building load. A preliminary investigation of the use of artificial neural network models to measure savings is presented. The methodology is demonstrated on case study examples using software specifically developed for the analysis of commercial building energy use.

Method for Determining Optimal Residential Energy Efficiency Retrofit Packages  

SciTech Connect

Businesses, government agencies, consumers, policy makers, and utilities currently have limited access to occupant-, building-, and location-specific recommendations for optimal energy retrofit packages, as defined by estimated costs and energy savings. This report describes an analysis method for determining optimal residential energy efficiency retrofit packages and, as an illustrative example, applies the analysis method to a 1960s-era home in eight U.S. cities covering a range of International Energy Conservation Code (IECC) climate regions. The method uses an optimization scheme that considers average energy use (determined from building energy simulations) and equivalent annual cost to recommend optimal retrofit packages specific to the building, occupants, and location. Energy savings and incremental costs are calculated relative to a minimum upgrade reference scenario, which accounts for efficiency upgrades that would occur in the absence of a retrofit because of equipment wear-out and replacement with current minimum standards.

Behavioral determinants of energy consumption in a centrally-heated apartment building  

Science Conference Proceedings (OSTI)

This paper discusses tenant perceptions and behavior regarding heating and ventilation in multifamily buildings. Data were collected at a 60-unit subsidized housing complex for senior citizens. The building has central steam heating and the fuel is neither billed nor metered to individual apartments. Winter indoor temperatures average 26/sup 0/C (79/sup 0/F). In order to explain behavior more fully than the simple statement ''tenants don't pay for the heat,'' we show how the tenants and maintenance staff act as a self-regulating system that determines heating system operation through local optimization. Using data from ethnographic interviews and a questionnaire survey of all the residents, the authors give quantitative measures of reported comfort and strategies for controlling comfort. They also discuss thee factors which tenants consider important for thermal comfort and their choices among various heat control strategies. For examples, why do only 35% use radiator valves to control the heat while 84% use windows. Implications are discussed for new construction and retrofit, as well as for equity and management policies. The authors argue that a proper understanding of the behavioral context in multifamily buildings is essential, both to avoid ineffective and costly retrofits and to suggest low-cost measures which address the behavioral determinants of energy use.

Pilot Residential Deep Energy Retrofits and the PNNL Lab Homes  

SciTech Connect

This report summarizes research investigating the technical and economic feasibility of several pilot deep energy retrofits, or retrofits that save 30% to 50% or more on a whole-house basis while increasing comfort, durability, combustion safety, and indoor air quality. The work is being conducted for the U.S. Department of Energy Building Technologies Program as part of the Building America Program. As part of the overall program, Pacific Northwest National Laboratory (PNNL) researchers are collecting and analyzing a comprehensive dataset that describes pre- and post-retrofit energy consumption, retrofit measure cost, health and comfort impacts, and other pertinent information for each home participating in the study. The research and data collection protocol includes recruitment of candidate residences, a thorough test-in audit, home energy modeling, and generation of retrofit measure recommendations, implementation of the measures, test-out, and continued evaluation. On some homes, more detailed data will be collected to disaggregate energy-consumption information. This multi-year effort began in October 2010. To date, the PNNL team has performed test-in audits on 51 homes in the marine, cold, and hot-humid climate zones, and completed 3 retrofits in Texas, 10 in Florida, and 2 in the Pacific Northwest. Two of the retrofits are anticipated to save 50% or more in energy bills and the others - savings are in the 30% to 40% range. Fourteen other retrofits are under way in the three climate zones. Metering equipment has been installed in seven of these retrofits - three in Texas, three in Florida, and one in the Pacific Northwest. This report is an interim update, providing information on the research protocol and status of the PNNL deep energy retrofit project as of December, 2011. The report also presents key findings and lessons learned, based on the body of work to date. In addition, the report summarizes the status of the PNNL Lab Homes that are new manufactured homes procured with minimal energy-efficiency specifications typical of existing homes in the region, and sited on the PNNL campus. The Lab Homes serve as a flexible test facility (the first of its kind in the Pacific Northwest) to rapidly evaluate energy-efficient and grid-smart technologies that are applicable to residential construction.

Predicted vs. Actual Energy Savings of Retrofitted House  

E-Print Network (OSTI)

This paper reports the results of actual energy savings and the predicted energy savings of retrofitted one-story house located in Dhahran, Saudi Arabia. The process started with modeling the house prior to retrofitting and after retrofitting. The monthly metered energy consumption is acquired from the electric company archives for seven years prior to retrofitting and recording the actual monthly energy consumption of the post retrofitting. The house model is established on DOE 2.1. Actual monthly energy consumption is used to calibrate and fine-tuning the model until the gap between actual and predicted consumption was narrowed. Then the Energy Conservation Measures (ECMs) are entered into the modeled house according to the changes in thermo-physical properties of the envelope and the changes in schedules and number of users. In order to account for those differences, electrical consumption attributed to A/C in summer was isolated and compared. The study followed the International Performance Measurement & Verification Protocol (IPMVP) in assessing the impact of energy conservation measures on actual, metered, building energy consumption. The study aimed to show the predicted savings by the simulated building model and the actual utility bills' analysis in air conditioning consumption and peak at monthly load due to building envelope.

Short-Term Test Results: Multifamily Home Energy Efficiency Retrofit  

SciTech Connect

Multifamily deep energy retrofits (DERs) represent great potential for energy savings, while also providing valuable insights on research-generated efficiency measures, cost-effectiveness metrics, and risk factor strategies for the multifamily housing industry. The Bay Ridge project is comprised of a base scope retrofit with a goal of achieving 30% savings (relative to pre-retrofit), and a DER scope with a goal of 50% savings (relative to pre-retrofit). The base scope has been applied to the entire complex, except for one 12-unit building which underwent the DER scope. Findings from the implementation, commissioning, and short-term testing at Bay Ridge include air infiltration reductions of greater than 60% in the DER building; a hybrid heat pump system with a Savings to Investment Ratio (SIR) > 1 (relative to a high efficiency furnace) which also provides the resident with added incentive for energy savings; and duct leakage reductions of > 60% using an aerosolized duct sealing approach. Despite being a moderate rehab instead of a gut rehab, the Bay Ridge DER is currently projected to achieve energy savings ? 50% compared to pre-retrofit, and the short-term testing supports this estimate.

Energy impacts of attic duct retrofits in Sacramento houses  

Science Conference Proceedings (OSTI)

Inefficiencies in air distribution systems have been identified as a major source of energy loss in US sunbelt homes. Research indicates that approximately 30--40% of the thermal energy delivered to the ducts passing through unconditioned spaces is lost through air leakage and conduction through the duct walls. Field experiments over the past several years have well documented the expected levels of air leakage and the extent to which that leakage can be reduced by retrofit. Energy savings have been documented to a more limited extent, based upon a few field studies and simulation model results. Simulations have also indicated energy loss through ducts during the off cycle caused by thermosiphon-induced flows, however this effect had not been confirmed experimentally. A field study has been initiated to separately measure the impacts of combined duct leak sealing and insulation retrofits, and to optimize a retrofit protocol for utility DSM programs. This paper describes preliminary results from 6 winter and 5 summer season houses. These retrofits cut overall duct leakage area approximately 64%, which translated to a reduction in envelope ELA of approximately 14%. Wrapping ducts and plenums with R-6 insulation translated to a reduction in average flow-weighted conduction losses of 33%. These experiments also confirmed the appropriateness of using duct ELA and operating pressures to estimate leakage flows for the population, but indicated significant variations between these estimates and measured flows on a house by house basis. In addition, these experiments provided a confirmation of the predicted thermosiphon flows, both under winter and summer conditions. Finally, average material costs were approximately 20% of the total retrofit costs, and estimates of labor required for retrofits based upon these experiments were: 0.04 person-hrs/cm{sup 2} of duct sealed and 0.21 person-hrs/m{sup 2} of duct insulated.

Field Assessment of Energy Audit Tools for Retrofit Programs  

SciTech Connect

This project focused on the use of home energy ratings as a tool to promote energy retrofits in existing homes. A home energy rating provides a quantitative appraisal of a home's asset performance, usually compared to a benchmark such as the average energy use of similar homes in the same region. Home rating systems can help motivate homeowners in several ways. Ratings can clearly communicate a home's achievable energy efficiency potential, provide a quantitative assessment of energy savings after retrofits are completed, and show homeowners how they rate compared to their neighbors, thus creating an incentive to conform to a social standard. An important consideration is how rating tools for the retrofit market will integrate with existing home energy service programs. For residential programs that target energy savings only, home visits should be focused on key efficiency measures for that home. In order to gain wide adoption, a rating tool must be easily integrated into the field process, demonstrate consistency and reasonable accuracy to earn the trust of home energy technicians, and have a low monetary cost and time hurdle for homeowners. Along with the Home Energy Score, this project also evaluated the energy modeling performance of SIMPLE and REM/Rate.

The RFF Home Energy Audit and Retrofit Survey...............................................................  

E-Print Network (OSTI)

Commercial and residential buildings are responsible for 42 percent of all U.S. energy consumption and 41 percent of U.S. CO2 emissions. Engineering studies identify several investments in new enegy-efficiency equipment or building retrofits that would more than pay for themselves in terms of lower future energy costs, but homeowners and businesses generally do not have good information about how to take advantage of these opportunities. Energy auditors make up a growing industry of professionals who evaluate building energy use and provide this information to building owners. This paper reports the results of a survey of nearly 500 home energy auditors and contractors that Resources for the Future conducted in summer 2011. The survey asked about the characteristics of these businesses and the services they provide, the degree to which homeowners follow up on their recommendations, and the respondents opinions on barriers to home energy retrofits and the role for government. Findings from the survey suggest that the audit industry only partially is filling the information gap. Not enough homeowners know about or understand audits, and the follow-through on recommendations once they do have audits is incomplete. But the survey findings suggest that low energy prices and the high cost of retrofits may be more responsible for these outcomes than failures of information.

Larsen, and Charles A. Goldman Conference Name 2011 ACEEE Summer Study on Energy Efficiency in Industry Date Published 2011 Publisher ACEEE Conference Location Niagara Falls, New York Abstract The U.S. energy service company (ESCO) industry is an example of a private-sector business model where energy efficiency savings are delivered to customers primarily through the use of performance-based contracts. Despite the onset of a severe economic recession, we estimate that the U.S. ESCO industry grew about 7% per year from 2006 to 2008 with annual revenues of about $4.1 billion in 2008. About 75% of industry revenues are directly related to the installation of energy efficiency measures at existing buildings in the institutional, commercial, and industrial sectors.

Energy savings from operation and maintenance training for apartment boiler heating systems. An energy study on ten low-income apartments  

SciTech Connect

The Portland Energy Office provided operation and maintenance (O&M) training to the operators of boiler heating systems for ten low-income apartment complexes in the Fall of 1990. This study tracked energy usage before and after O&M training to see if savings occurred. Training was provided on both weatherized and non-weatherized apartments to find out if weatherization impacted the amount of O&M savings to be obtained. Also, energy savings from the O&M training and building shell weatherization are compared. The O&M training averaged about four hours per building. Content was adjusted at each site to match needs of the boiler and operator. The Energy Office also provided a boiler tune-up by a service technician. The training stressed low-cost and no-cost measures which operators could either do themselves or hire service help to implement. It also emphasized boiler safety. Nine of the ten apartment complexes in the study used less energy per heating degree-day after the O&M help. Average savings were 10%. Four apartments chosen randomly as controls had negative savings; they used slightly more energy during the same post-O&M time frame. Weatherized and unweatherized apartments showed similar savings after the O&M help, 10% and 11% percent respectively. Savings from weatherization of six of the apartments in the winter of 1988--1989 were also measured. A low average of only 4% was observed, reflecting negative savings in two buildings.

Calculating Energy and Demand Retrofit Savings for Victoria High School: Interim Report  

E-Print Network (OSTI)

As part of the LoanSTAR program, Victoria High School in Victoria, Texas underwent two retrofits: a) an absorption chiller was changed to an electric vapor compression chiller, and b) an EMCS system was installed after about 5 months in the post retrofit period. Moreover, retrofit savings calculation was complex since pre-retrofit data consisted of only monthly utility data while hourly monitored data are available for the post-retrofit period. This report describes the method in which we have performed retrofit energy and demand savings in Victoria High School. A previous report described the procedure adopted when no pre-retrofit data are available. We have only used Unnormalized Utility Bills Comparison ,or the Level-0 approach to determine electricity (energy and demand) and gas energy savings for VHS.

The Institutional Conservation Program: A Funding Option for Energy Retrofits  

E-Print Network (OSTI)

The Institutional Conservation Program (ICP) provides matching grants to K-12 schools, colleges/universities, and hospitals for energy-related retrofit studies and the implementation of capital projects identified, analyzed, and recommended by these studies. Although grant dollars for the program are still appropriated at the federal level, Petroleum Violation Escrow (PVE) monies returned to the states now provide the largest source of ICP funds for most states. The program is administered at the federal level by the Department of Energy and at the state level in Texas by the Governor's Energy Management Center. The purpose of the ICP is to assist eligible institutions in reducing energy consumption and its attendant costs. More specifically, the program gives an institution the financial incentive to hire a professional engineer to identify and analyze the most attractive package of energy retrofits for a given building. Matching financial assistance is then available for implementing part or all of the recommended measures. Typical projects funded through the program include computerized energy management systems, lighting system change-outs, boiler modifications, and HVAC change-outs and modifications. Funded projects must have a payback of 2-10 years and must be installed in buildings completed and occupied before April 20, 1977. All applications submitted for funding consideration are subject to a programmatic and technical review. Applications compete for available monies according to specific criteria set for Technical Assistance Grants (study grants) and Energy Conservation Measures Grants (retrofit implementation grants). Since 1979 ten ICP funding cycles have been held in Texas, and a program cycle funded by PVE dollars returned to the state is currently in progress. An eleventh funding cycle, using federally appropriated dollars, and a second "oil overcharge" cycle are anticipated for FY 89.

An Overview of the Building Energy Retrofit Research Program  

E-Print Network (OSTI)

This research update presents the status of a U.S. Department of Energy program that addresses the technical, financial, and behavioral barriers to improving the energy efficiency of existing buildings. The program is implemented with expertise from four national laboratories, Princeton University, and the Alliance to Save Energy in cooperation with a large number of state, utility, and local agencies. The remaining potential for energy savings from cost effective retrofit measures in existing buildings is impressive, but a variety of barriers have been identified that reduce conservation investment. One significant barrier that the program can address is the large uncertainty about savings. Average savings for a large sample of retrofit hones is generally lower than expected, and savings in individual buildings varies unpredictably from negative to very high positive values. Our approach has been to provide reliable information on the performance and cost effectiveness of energy conserving technologies and practices. Field performance monitoring is in progress in each building sector and development of diagnostic techniques and monitoring protocols is in progress.

Group Home Energy Efficiency Retrofit for 30% Energy Savings: Washington, D.C. (Fact Sheet)  

SciTech Connect

Energy efficiency retrofits (EERs) face many challenges on the path to scalability. Limited budgets, cost effectiveness, risk factors, and accessibility impact the type and the extent of measures that can be implemented feasibly to achieve energy savings goals. Group home retrofits can face additional challenges than those in single family homes - such as reduced access (occupant-in-place restrictions) and lack of incentives for occupant behavioral change. This project studies the specification, implementation, and energy savings from an EER in a group home, with an energy savings goal of 30%. This short term test report chronicles the retrofit measures specified, their projected cost-effectiveness using building energy simulations, and the short term test results that were used to characterize pre-retrofit and post-retrofit conditions. Additionally, the final report for the project will include analysis of pre- and post-retrofit performance data on whole building energy use, and an assessment of the energy impact of occupant interface with the building (i.e., window operation). Ultimately, the study's results will be used to identify cost effective EER measures that can be implemented in group homes, given constraints that are characteristic of these buildings. Results will also point towards opportunities for future energy savings.

Research on Commercial Patterns of China Existing Building Energy Retrofit Based on Energy Management Contract  

E-Print Network (OSTI)

Existing building energy retrofit is one of the keys of building energy efficiency in China. According to experience in developed countries, implementation of energy management contract (EMC) is crucial to promote existing building energy retrofit, which means that the reduction of energy expenditure is used to pay the retrofit cost. The EMC program has a short payback period, high interior return rate and remarkable energy savings. This paper present the specialties and difficulties of existing building energy conservation in China and the development, service items and commercial patterns of EMC. We discuss the main methods and ways that EMC is applied to existing building energy retrofit at the original stage of building energy efficiency by analyzing the difference of EMC and other traditional energy efficiency patterns. Based on the analysis of three commercial patterns of EMC including guaranteed savings contract, shared savings contract and chauffage contract, we propose that the guaranteed savings contract is the main development direction of building energy efficiency service in China. At the same time, new financing methods and energy-saving measurement and verification standards should be established to ensure that EMC plays an important role in the process of existing building energy retrofit in China.

Short-Term Test Results: Transitional Housing Energy Efficiency Retrofit in the Hot-Humid Climate  

SciTech Connect

This project evaluates the renovation of a 5,800 ft2, multi-use facility located in St. Petersburg, on the west coast of central Florida, in the hot humid climate. An optimal package of retrofit measures was designed to deliver 30-40% annual energy cost savings for this building with annual utility bills exceeding $16,000 and high base load consumption. Researchers projected energy cost savings for potential retrofit measures based on pre-retrofit findings and disaggregated, weather normalized utility bills as a basis for simulation true-up. A cost-benefit analysis was conducted for the seven retrofit measures implemented; adding attic insulation and sealing soffits, tinting windows, improving whole building air-tightness, upgrading heating and cooling systems and retrofitting the air distribution system, replacing water heating systems, retrofitting lighting, and replacing laundry equipment. The projected energy cost savings for the full retrofit package based on a post-retrofit audit is 35%. The building's architectural characteristics, vintage, and residential and commercial uses presented challenges for both economic projections and retrofit measure construction.

SciTech Connect

Under this project, Newport Partners (as part of the BA-PIRC research team) evaluated the installation, measured performance, and cost-effectiveness of efficiency upgrade measures for a tenant-in-place DER at the Bay Ridge multifamily (MF) development in Annapolis, Maryland. The design and construction phase of the Bay Ridge project was completed in August 2012. This report summarizes system commissioning, short-term test results, utility bill data analysis, and analysis of real-time data collected over a one-year period after the retrofit was complete. The Bay Ridge project is comprised of a 'base scope' retrofit which was estimated to achieve a 30%+ savings (relative to pre-retrofit) on 186 apartments, and a 'DER scope' which was estimated to achieve 50% savings (relative to pre-retrofit) on a 12-unit building. The base scope was applied to the entire apartment complex, except for one 12-unit building which underwent the DER scope. A wide range of efficiency measures was applied to pursue this savings target for the DER building, including improvements/replacements of mechanical equipment and distribution systems, appliances, lighting and lighting controls, the building envelope, hot water conservation measures, and resident education. The results of this research build upon the current body of knowledge of multifamily retrofits. Towards this end, the research team has collected and generated data on the selection of measures, their estimated performance, their measured performance, and risk factors and their impact on potential measures.

In 2009, the state of Nevada received nearly forty million dollars in Neighborhood Stabilization Funds from the Department of Housing and Urban Development. The purpose of this funding was to stabilize communities that have suffered from foreclosures and abandonment. In an effort to provide guidance to local officials and maximize how effectively this NSP funding is utilized in retrofitting homes, CARB provided design specifications, energy modeling, and technical support for the Building America Retrofit Alliance (BARA) team and its local partners - Better Building Performance, Nevada Energy Star Partners Green Alliance, and Home Free Nevada - for two retrofit test homes. One home was to demonstrate a modest retrofit and the other a deep energy retrofit. Through this project, CARB has provided two robust solution packages for retrofitting homes built in this region between the 1980s and early 1990s without substantially inconveniencing the occupants. The two test homes, the Carmen and Sierra Hills, demonstrate how cost-effectively energy efficient upgrades can be implemented in the hot, dry climate of the Southwest. In addition, the homes were used as an educational experience for home performance professionals, building trades, remodelers, and the general public. In-field trainings on air-sealing, HVAC upgrades, and insulating were provided to local contractors during the retrofit and BARA documented these retrofits through a series of video presentations, beginning with a site survey and concluding with the finished remodel and test out.

Actual and Estimated Energy Savings Comparison for Deep Energy Retrofits in the Pacific Northwest  

Science Conference Proceedings (OSTI)

Seven homes from the Pacific Northwest were selected to evaluate the differences between estimated and actual energy savings achieved from deep energy retrofits. The energy savings resulting from these retrofits were estimated, using energy modeling software, to save at least 30% on a whole-house basis. The modeled pre-retrofit energy use was trued against monthly utility bills. After the retrofits were completed, each of the homes was extensively monitored, with the exception of one home which was monitored pre-retrofit. This work is being conducted by Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy Building Technologies Program as part of the Building America Program. This work found many discrepancies between actual and estimated energy savings and identified the potential causes for the discrepancies. The differences between actual energy use and modeled energy use also suggest improvements to improve model accuracy. The difference between monthly whole-house actual and estimated energy savings ranged from 75% more energy saved than predicted by the model to 16% less energy saved for all the monitored homes. Similarly, the annual energy savings difference was between 36% and -14%, which was estimated based on existing monitored savings because an entire year of data is not available. Thus, on average, for all six monitored homes the actual energy use is consistently less than estimates, indicating home owners are saving more energy than estimated. The average estimated savings for the eight month monitoring period is 43%, compared to an estimated savings average of 31%. Though this average difference is only 12%, the range of inaccuracies found for specific end-uses is far greater and are the values used to directly estimate energy savings from specific retrofits. Specifically, the monthly post-retrofit energy use differences for specific end-uses (i.e., heating, cooling, hot water, appliances, etc.) ranged from 131% under-predicted to 77% over-predicted by the model with respect to monitored energy use. Many of the discrepancies were associated with occupant behavior which influences energy use, dramatically in some cases, actual versus modeled weather differences, modeling input limitations, and complex homes that are difficult to model. The discrepancy between actual and estimated energy use indicates a need for better modeling tools and assumptions. Despite the best efforts of researchers, the estimated energy savings are too inaccurate to determine reliable paybacks for retrofit projects. While the monitored data allows researchers to understand why these differences exist, it is not cost effective to monitor each home with the level of detail presented here. Therefore an appropriate balance between modeling and monitoring must be determined for more widespread application in retrofit programs and the home performance industry. Recommendations to address these deficiencies include: (1) improved tuning process for pre-retrofit energy use, which currently utilized broad-based monthly utility bills; (2) developing simple occupant-based energy models that better address the many different occupant types and their impact on energy use; (3) incorporating actual weather inputs to increase accuracy of the tuning process, which uses utility bills from specific time period; and (4) developing simple, cost-effective monitoring solutions for improved model tuning.

Test Methods and Protocols for Environmental and Safety Hazards Associated with Home Energy Retrofits  

SciTech Connect

A number of health hazards and hazards to the durability of homes may be associated with energy retrofitting and home renovation projects. Among the hazards associated with energy retrofit work, exposure to radon is thought to cause more than 15,000 deaths per year in the U.S., while carbon monoxide poisoning results in about 20,000 injuries and 450 deaths per year. Testing procedures have been developed for identifying and quantifying hazards during retrofitting. These procedures commonly include a battery of tests to screen combustion appliances for safe operation, including worst case depressurization measurement, backdrafting (spillage) under depressurized or normal conditions, and carbon monoxide production.

Specification and cost manual for energy retrofits on small commercial and multifamily buildings  

DOE Green Energy (OSTI)

This specification/cost manual was prepared as part of DOE's technical assistance to the states, utilities and other groups participating in the Commercial and Apartment Conservation Service (CACS) program. The intention is to provide a set of standardized specifications and cost information for the CACS program measures. The material was designed to be used primarily by contractors and others in preparing cost estimates at the request of CACS utilities. This information can also be used by CACS participants in preparing state plans, analyzing which measures are best-suited for their particular climates, computing paybacks, and carrying out audits. In addition, this publication may be of interest to the wider audience involved in the energy retrofit field, ranging from architects and engineers to energy auditors and building inspectors. Each specification contains several categories of information: title; description; recommendations; materials; installation; maintenance; cost information; material cost variables, installation cost variables, regional variables, and safety/hazard issues. The document is divided into six sections: building envelope and service insulation measures; HVAC measures: simple systems; HVAC measures: complex systems; lighting system measures; active solar system measures; and passive solar system measures.

Advanced Energy Retrofit Guide (AERG): Practical Ways to Improve Energy Performance; Healthcare Facilities (Book)  

SciTech Connect

The Advanced Energy Retrofit Guide for Healthcare Facilities is part of a series of retrofit guides commissioned by the U.S. Department of Energy. By presenting general project planning guidance as well as detailed descriptions and financial payback metrics for the most important and relevant energy efficiency measures (EEMs), the guides provide a practical roadmap for effectively planning and implementing performance improvements in existing buildings. The Advanced Energy Retrofit Guides (AERGs) are intended to address key segments of the U.S. commercial building stock: retail stores, office buildings, K-12 schools, grocery stores, and healthcare facilities. The guides' general project planning considerations are applicable nationwide; the energy and cost savings estimates for recommended EEMs were developed based on energy simulations and cost estimates for an example hospital tailored to five distinct climate regions. These results can be extrapolated to other U.S. climate zones. Analysis is presented for individual EEMs, and for packages of recommended EEMs for two project types: existing building commissioning projects that apply low-cost and no-cost measures, and whole-building retrofits involving more capital-intensive measures.

Cost Savings and Energy Reduction: Bi-Level Lighting Retrofits in Multifamily Buildings  

E-Print Network (OSTI)

Community Environmental Center implements Bi- Level Lighting fixtures as a component of cost-effective multifamily retrofits. These systems achieve substantial energy savings by automatically reducing lighting levels when common areas are unoccupied. Because there is a lack of empirical evidence documenting the performance of these systems, this paper uses electric consumption data collected from buildings before and after retrofits were performed, and analyzes the cost and consumption savings achieved through installation of Bi-Level Lighting systems. The results of this report demonstrate that common areas that are currently not making use of Bi-Level lighting systems would achieve significant financial and environmental benefits from Bi-Level focused retrofits. This project concludes that building codes should be updated to reflect improvements in Bi-Level Lighting technologies, and that government-sponsored energy efficiency programs should explicitly encourage or mandate Bi-Level Lighting installation components of subsidized retrofit projects.

On Target: A Complicated and Successful Energy Retrofit Program  

E-Print Network (OSTI)

The Lone Star Gas Corporate headquarters, in Dallas, Texas, consists of a five building, 355,000 square foot office complex with buildings ranging in age from 14 - 60 years old between 20,000 - 100,000 square feet (SF), and with multiple HVAC systems served by two central plants. The company was facing the inevitable increase in electric utility costs knowing that two reactors at a new construction nuclear power plant would be coming on line over during the next five years. By taking a proactive stance, a six month detailed energy audit commenced after a thorough internal energy analysis was conducted. The result of the audit was a multi-year $1.7 million retrofit project encompassing nearly 20 major items would be implemented over three years. Total energy and cost avoidance savings were calculated to yield a simple pay back of 1.5 years and a cash pay out of 3.5 years. Total energy reductions of 32% were achieved and the predicted economics realized. The various projects involved the application of nearly 18,000 square feet of window tinting, a total facility relamping and efficiency improvement project, installation of more efficient filtration systems, installation of control valves on the chillwater system, installation of a building automation system, installation of a plate heat exchanger for hydronic free-cooling, isolation of after-hours and 24-hour cooling loads on a separate loop, isolation and conversion of 24-hour steam requirements to reduce excess boiler capacity and run time, improvement of return air systems, the replacement and increase of cooling tower capacity, implement a preventive maintenance program, and improved operating procedures that focused on demand side management without thermal storage. The combined results of these single projects enabled the facility to remove and not replace 25% of the physical plant cooling equipment (one single-effect steam absorber) upon reaching the end of its expected life. Project costs and avoided savings were tracked monthly throughout the three year period. Additional energy and cost avoidance tracking for two more years was completed. In five years, a positive cash flow of more than $550,00 is only 9% less than the original projection. Improved employee comfort and enhanced space conditions have returned significant benefits to the work force of nearly one thousand people occupying this facility.

Measuring energy-saving retrofits: Experiences from the Texas LoanSTAR program  

SciTech Connect

In 1988 the Governor`s Energy Management Center of Texas received approval from the US Department of Energy to establish a $98.6 million state-wide retrofit demonstration revolving loan program to fund energy-conserving retrofits in state, public school, and local government buildings. As part of this program, a first-of-its-kind, statewide Monitoring and Analysis Program (MAP) was established to verify energy and dollar savings of the retrofits, reduce energy costs by identifying operational and maintenance improvements, improve retrofit selection in future rounds of the LoanSTAR program, and initiate a data base of energy use in institutional and commercial buildings located in Texas. This report discusses the LoanSTAR MAP with an emphasis on the process of acquiring and analyzing data to measure savings from energy conservation retrofits when budgets are a constraint. This report includes a discussion of the program structure, basic measurement techniques, data archiving and handling, data reporting and analysis, and includes selected examples from LoanSTAR agencies. A summary of the program results for the first two years of monitoring is also included.

Energy and Cost Savings of Retro-Commissioning and Retrofit Measures for Large Office Buildings  

Science Conference Proceedings (OSTI)

This paper evaluates the energy and cost savings of seven retro-commissioning measures and 29 retrofit measures applicable to most large office buildings. The baseline model is for a hypothetical building with characteristics of large office buildings constructed before 1980. Each retro-commissioning measure is evaluated against the original baseline in terms of its potential of energy and cost savings while each retrofit measure is evaluated against the commissioned building. All measures are evaluated in five locations (Miami, Las Vegas, Seattle, Chicago and Duluth) to understand the impact of weather conditions on energy and cost savings. The results show that implementation of the seven operation and maintenance measures as part of a retro-commissioning process can yield an average of about 22% of energy use reduction and 14% of energy cost reduction. Widening zone temperature deadband, lowering VAV terminal minimum air flow set points and lighting upgrades are effective retrofit measures to be considered.

Strategy Guideline: Energy Retrofits for Low-Rise Multifamily Buildings in Cold Climates  

SciTech Connect

This Strategy Guideline explains the benefits of evaluating and identifying energy efficiency retrofit measures that could be made during renovation and maintenance of multifamily buildings. It focuses on low-rise multifamily structures (three or fewer stories) in a cold climate. These benefits lie primarily in reduced energy use, lower operating and maintenance costs, improved durability of the structure, and increased occupant comfort. This guideline focuses on retrofit measures for roof repair or replacement, exterior wall repair or gut rehab, and eating system maintenance. All buildings are assumed to have a flat ceiling and a trussed roof, wood- or steel-framed exterior walls, and one or more single or staged boilers. Estimated energy savings realized from the retrofits will vary, depending on the size and condition of the building, the extent of efficiency improvements, the efficiency of the heating equipment, the cost and type of fuel, and the climate location.

Occupant-in-Place Energy Efficiency Retrofit in a Group Home for 30% Energy Savings in Climate Zone 4  

SciTech Connect

Energy efficiency retrofits (EERs) face many challenges on the path to scalability. Limited budgets, cost effectiveness, risk factors, and accessibility impact the type and the extent of measures that can be implemented feasibly to achieve energy savings goals. Group home retrofits can face additional challenges than those in single family homes - such as reduced access (occupant-in-place restrictions) and lack of incentives for occupant behavioral change. This project studies the specification, implementation, and energy savings from an EER in a group home, with an energy savings goal of 30%. This short term test report chronicles the retrofit measures specified, their projected cost-effectiveness using building energy simulations, and the short term test results that were used to characterize pre-retrofit and post-retrofit conditions. Additionally, the final report for the project will include analysis of pre- and post-retrofit performance data on whole building energy use, and an assessment of the energy impact of occupant interface with the building (i.e., window operation). Ultimately, the study's results will be used to identify cost effective EER measures that can be implemented in group homes, given constraints that are characteristic of these buildings. Results will also point towards opportunities for future energy savings.

Persistence of energy savings of lighting retrofit technologies at the Forrestal Building  

SciTech Connect

In 1989, the Forrestal Building, headquarters for the U.S. Department of Energy, was chosen for a major lighting retrofit project. The project replaced the aging fighting system newer, energy-efficient fixtures. Pacific Northwest Laboratory conducted a three-part monitoring study at the Forrestal Building to (1) characterize building energy use, (2) empirically measure savings realized by the lighting retrofit, and (3) determine the persistence of energy savings. This report summarizes the findings from the third and final monitoring phase. Two data loggers were left installed at the Forrestal Building and data were collected for a 12-month period after the lighting retrofit was completed. An analysis-of-variance test indicated that the mean monthly lighting demand is increasing. A regression analysis performed on the data indicated that the mean monthly lighting demand for workdays is increasing at a rate of 0.3652{+-}0.1101 kW/mo. The nonworkday demand is increasing at a rate of 0.3408{+-}0.1027 kW/mo. During the same period, workday mean monthly plug load demand increased 0.0912{+-}0.0275 kW/mo., while nonworkday plug loads decreased slightly. The gradual increase, though significant, is reduced when compared to the 56% savings recorded after the lighting retrofit. The increase is attributed to a combination of occupants returning to original (pre-retrofit poor) behavior and a small set of occupancy sensors being defeated by building occupants. Degradation of lighting fixtures from {open_quotes}burn-in time{close_quotes} was ruled out because all burn-in time is expected in the first few months and the increasing trend persists over the 11 months of this study. Because the lighting demand was still increasing at the end of the study, without further data collection, it was not possible to determine when the increase would level out. Therefore, the true energy savings from the lighting retrofit remain unknown.

A Bin Method for Calculating Energy Conservation Retrofit Savings in Commercial Buildings  

E-Print Network (OSTI)

The calculation of measured energy savings from energy conservation retrofits is an important step in the verification of the success of a retrofit (Claridge et al. 1992). Several methods for calculating the savings from energy conservation retrofits to HVAC systems in the LoanSTAR program have been proposed, including linear and change-point linear empirical models and calibrated simulation models. Simple least squares linear regression is easiest to use and understand, but is incapable of describing non-linear temperature dependencies of a building's energy use. Change-point linear models are more complex than the simple linear regression and cover a broader range of buildings. However, there are some buildings for which change-point linear models do not fit the data adequately. This paper presents a first look at an hourly bin method for calculating energy savings from energy conservation retrofits to HVAC systems based on hourly whole-building electricity, sub-metered motor control center use and thermal energy measurements. A general procedure for determining the appropriate number of bins is described and the bin method is applied to data from several agencies participating in the LoanSTAR program. Results are compared to existing savings calculation procedures for two buildings.

FLASTAR: Measured Savings of a Comprehensive Energy Retrofit in a Florida Elementary School  

E-Print Network (OSTI)

This paper describes the final results for the pilot demonstration of the Florida Public Building Loan Concept. This loan program was intended to provide low cost funds to eligible public entities for upgrade of building energy systems. The site was an elementary school in Central Florida which served as the pilot project to demonstrate energy savings in public buildings similar to that achieved by the Texas LOANSTAR program (Verdict et.al., 1990). Termed FLASTAR (Florida Alliance for Saving Taxes and Resources), the study entailed the comprehensive metering of a test site to demonstrate energy savings potential. Over twenty channels of weather and submetered energy data have been collected since April 12.1995. Annual billed energy consumption for the 41.000 square foot facility was approximately 775,000 kWh (60 kBtu/ft^2) or $55,200 in the base year (1994). During the summer of 1995, replacement of aging chillers resulted in 30% reduction to cooling energy use. The second retrofit was occupancy sensor controls for classroom and office lighting which were installed in December 1995. However, post retrofit data showed that metered lighting energy use actually increased after the occupancy sensors were installed. Our data, and that of other projects. suggests that the occupancy sensor retrofit may have increased lighting on-times. Previously school personnel practiced responsible manual switching. but then came to depend on automatic control after the retrofit. The final project retrofit saw an energy management system (EMS) added in the summer of 1996. The system provided direct digital control @DC) of the school chiller, air handlers and packaged direct expansion (DX) roof-top cooling systems. The EMS equipment reduced chiller energy use by a further 16% and air handling and DX system energy consumption by 30%. The project retrofits were found to reduce overall school energy use by approximately 15% or 120.000 kWh per year. The annual energy savings totaled $4,600 at current energy prices, although the retrofits did not significantly impact facility peak load.

Advanced Energy Retrofit Guide: Practical Ways to Improve Energy Performance, K-12 Schools (Book)  

SciTech Connect

The U.S. Department of Energy developed the Advanced Energy Retrofit Guides (AERGs) to provide specific methodologies, information, and guidance to help energy managers and other stakeholders plan and execute energy efficiency improvements. Detailed technical discussion is fairly limited. Instead, we emphasize actionable information, practical methodologies, diverse case studies, and unbiased evaluations of the most promising retrofit energy efficiency measures for each building type. A series of AERGs is under development, addressing key segments of the commercial building stock. K-12 schools were selected as one of the highest priority building sectors, because schools affect the lives of most Americans. They also represent approximately 8% of the energy use and 10% of the floor area in commercial buildings nationwide. U.S. K-12 school districts spend more than $8 billion each year on energy - more than they spend on computers and textbooks combined. Most occupy older buildings that often have poor operational performance - more than 30% of schools were built before 1960. The average age of a school is about 42 years - which is nearly the expected serviceable lifespan of the building. K-12 schools offer unique opportunities for deep, cost-effective energy efficiency improvements, and this guide provides convenient and practical guidance for exploiting these opportunities in the context of public, private, and parochial schools.

Oil Field Electrical Energy Savings Through Energy-Efficient Motor Retrofits  

E-Print Network (OSTI)

The Wyoming Electric Motor Training and Testing Center (WEMTTC), in conjunction with the Department of Energy-Denver Support Office and the Naval Petroleum Reserve #3 (NPR-3), has conducted an extensive study of electric motor efficiency at the Reserve's oil field near Casper, Wyoming. As a result of this project, WEMTTC has developed a new test method for estimating an electric motor's operating efficiency, and the instrumentation to implement this test method. Using the new test method and instrumentation, several oversized or inefficient motors were replaced with new generation, high-efficiency motors, and the savings documented. This paper describes the test method and instrumentation developed by WEMTTC. The results obtained from the actual energy-efficient motor retrofits are also presented.

Cost-Effectiveness of Home Energy Retrofits in Pre-Code Vintage Homes in the United States  

SciTech Connect

This analytical study examines the opportunities for cost-effective energy efficiency and renewable energy retrofits in residential archetypes constructed prior to 1980 (Pre-Code) in fourteen U.S. cities. These fourteen cities are representative of each of the International Energy Conservation Code (IECC) climate zones in the contiguous U.S. The analysis is conducted using an in-house version of EnergyGauge USA v.2.8.05 named CostOpt that has been programmed to perform iterative, incremental economic optimization on a large list of residential energy efficiency and renewable energy retrofit measures. The principle objectives of the study are as follows: to determine the opportunities for cost effective source energy reductions in this large cohort of existing residential building stock as a function of local climate and energy costs; and to examine how retrofit financing alternatives impact the source energy reductions that are cost effectively achievable.

Embedding Continuous Commissioning in an Energy Efficiency Retrofit Program  

E-Print Network (OSTI)

his paper presents a case study where Continuous Commissioning (CC), a process that optimizes the HVAC system operation and controls to reduce the building energy consumption and improve comfort, was embedded as one Energy Cost Reduction Measure (ECRM) in a $2.7 million energy efficiency program. The program covers four campuses and two administrative office buildings of a community college district, with a total conditioned area of 2.35 million square feet. Cumulative cost savings of over $1.7 million have been achieved since the start of the program in mid-2002. Savings as a direct result of the CC efforts account for almost 2/3 of the total cost reduction. This paper discusses major commissioning activities for the central plants and building heating, ventilation, and air conditioning (HVAC) systems, as well as how deferred maintenance issues, key to the success of any commissioning project, were addressed and adminstered by the CC engineer.

A Calibration Methodology for Retrofit Projects Using Short-Term Monitoring and Disaggregated Energy Use Data  

E-Print Network (OSTI)

This paper presents an improved methodology to calibrate energy simulation models to better represent the actual energy use breakdowns in existing buildings. The goal of this methodology is to help architects and engineers accurately determine the current energy use and identify any energy-related problems in the building before proposing the retrofit design solutions, without conducting long-term monitoring. The methodology includes procedures to conduct systematic data collection, "on-off' tests to determine the power densities of the electrical loads, up to four weeks of building energy monitoring to derive the energy use profiles and temperature settings, and disaggregation of the measured energy use data. The procedures also utilize the monthly utility billing records and site weather data. The calibration to the measured data is done on both hourly and monthly basis. The procedures are built into a computer program and integrated with previously developed simulation software. The user interface of the program includes guidelines to help the user decide which simulation input variable has to be altered in order to match the measured data. It also produces graphical outputs to help in visualizing the results, and several guidelines to help study different retrofit strategies after the model has been calibrated.

Measured energy savings and economics of retrofitting existing single-family homes: An update of the BECA-B database  

SciTech Connect

The energy bill for US single-family households was over $77 billion in 1987 (excluding auto fuel purchases), accounting for approximately 20% of national energy expenditures. Large sums are spent on residential retrofits by individual homeowners, government agencies, and utilities. As of late 1987, over 21 million households indicated that they had added at least one energy-saving measure in the previous two years, while a recent Electric Power Research Institute (EPRI) study estimated that nearly 15 million residential customers have participated in some kind of demand-side management (DSM) program. Given the level of continuing investments in residential energy efficiency, accurate estimates of savings from various conservation measures are increasingly necessary, especially as new technologies become more sophisticated and incremental efficiency gains more difficult to achieve. This report provides a comparative analysis of measured data on the performance and cost-effectiveness of energy-saving measures in existing single-family homes, based on information in the Buildings Energy-Use Compilation and Analysis (BECA) data base. The initial BECA report on measured data for single-family retrofits was completed seven years ago. In updating the single-family database, we have added 135 data points, representing over 33,000 houses, to the original database of 145 retrofit projects. The report is organized in two volumes. Volume 1 provides a summary of energy savings and costs of individual retrofit measures and strategies and results from federal/state low-income and utility weatherization programs. we also discuss measurement issues, predicted versus actual savings, trends in single-family retrofit programs, and implications for the next generation'' of cost-effective single-family retrofits. Volume 2 contains a written summary of each retrofit project and complete data tables. 87 refs., 20 figs., 16 tabs.

Calculating Energy and Demand Retrofit Savings for Stroman High School: Interim Report  

E-Print Network (OSTI)

As part of the LoanSTAR program, Stroman High School in Victoria Texas underwent two retrofits: a) an absorption chiller was changed to an electric vapor compression chiller, and b) an EMCS system was installed after about 5 months in the post retrofit period. Moreover, retrofit savings calculation was complex since pre-retrofit data consisted only of monthly utility data while hourly monitored data are available for the post-retrofit period. The retrofit savings in electricity and gas were computed by two different approaches: Unnormalized Utility Bill Comparison and Weather and Schedule Normalized Utility Bill Comparison Using Post-Retrofit Daily Models. (For purpose of simplicity, in this report, we will refer them as Level-0 and Level-1, respectively.) This report describes these approaches and discusses how well the retrofit savings predicted by both approaches compare with each other. It also describes the procedure for determining demand savings.

Simulation of the Post-Retrofit Thermal Energy Use for the Perry-Castaneda Library Building with the Use of Simplified System Models  

E-Print Network (OSTI)

Several state owned buildings with dual-duct constant volume (DDCV) systems are being retrofitted with energy efficient variable air volume (VAV) systems as part of Texas LoanSTAR Program. One method of determining the energy savings resulting from energy conserving retrofits relies on the use of a model for the daily whole building consumption, Epre, in the pre-retrofit configuration. Epre is typically a function of primary influencing parameters such as ambient temperature, humidity, building internal gains and others (Figure 1). Following the retrofit, the energy saved, E,av is determined using measured daily consumption, Emea3 as shown in Figure 1. This method is being used in the Texas LoanSTAR monitoring and analysis program for buildings that have adequate pre-retrofit monitored data. Unfortunately, in the Perry-Castaneda Library (PCL) building, the retrofits were completed before the monitoring instrumentation was installed. Therefore, no pre-retrofit monitored data are available for this building. Hence another method to estimate savings is needed. Such a method was developed and tested (Katipamula and Claridge 1991). This method was based on the use of the ASHRAE TC 4.7 simplified energy analysis procedure (SEAP). It involved developing one model each for the VAV (post-retrofit system) and the DDCV (pre-retrofit system) systems.

Retrofit Options for Increasing Energy Efficiency in Office Buildings- Methodology Review  

E-Print Network (OSTI)

Portuguese Buildings represent 35% of primary energy consumption in 2006, with non-residential sector representing almost half of this number globally and around 65% in Lisbon city. Expected to grow 5% yearly in this period, non-residential buildings rehabilitation is a great opportunity for energy rehabilitation for a stock of 800.000 buildings needing medium to high interventions. For this task to be successful it is also urgent that procedures consider an accurate technical framework, where existing technologies and best case-studies can be considered, in order to drive passive measures retrofitting forward. This paper presents an overview of a methodology development which pretends to include the energy component in rehabilitation schemes with an integrated and comprehensive analysis, achieving all those directly involved in the building process (owners, consumers, public bodies, construction and project design industry) as well as new important players such as ESCOs.

Much of the literature proposes using power from the existing coal plant and thermal integration of its supercritical steam cycle with the stripper reboiler to supply the energy needed for solvent regeneration and CO2 compression. This study finds that using an auxiliary natural gas turbine plant to meet the energetic demands of carbon capture and compression may make retrofits more attractive compared to using thermal integration in some circumstances. Natural gas auxiliary plants increase the power output of the base plant and reduce technological risk associated with CCS, but require favorable natural gas prices and regional electricity demand for excess electricity to make using an auxiliary plant more desirable. Three different auxiliary plant technologies were compared to integration for 90 % capture from an existing, 500 MW supercritical coal plant. CO2 capture and compression is simulated using Aspen Plus and a monoethylamine (MEA) absorption process. Thermoflow software is used to simulate three gas plant technologies. The three technologies assessed are the

Evaluation of Retrofit Delivery Packages  

SciTech Connect

Residential energy retrofit activities are a critical component of efforts to increase energy efficiency in the U.S. building stock; however, retrofits account for a small percentage of aggregate energy savings at relatively high per unit costs. This report by Building America research team, Alliance for Residential Building Innovation (ARBI), describes barriers to widespread retrofits and evaluates opportunities to improve delivery of home retrofit measures by identifying economies of scale in marketing, energy assessments, and bulk purchasing through pilot programs in portions of Sonoma, Los Angeles, and San Joaquin Counties, CA. These targeted communities show potential and have revealed key strategies for program design, as outlined in the report.

Bay Ridge Gardens - Mixed Humid Affordable Multifamily Housing Deep Energy Retrofit: Annapolis, Maryland. Building America Case Study: Efficient Solutions for New and Existing Homes (Fact Sheet)  

SciTech Connect

Under this project, Newport Partners (as part of the BA-PIRC research team) evaluated the installation, measured performance, and cost-effectiveness of efficiency upgrade measures for a tenant-in-place DER at the Bay Ridge multifamily (MF) development in Annapolis, Maryland. The design and construction phase of the Bay Ridge project was completed in August 2012. This report summarizes system commissioning, short-term test results, utility bill data analysis, and analysis of real-time data collected over a one-year period after the retrofit was complete. The Bay Ridge project is comprised of a "base scope" retrofit which was estimated to achieve a 30%+ savings (relative to pre-retrofit) on 186 apartments, and a "DER scope" which was estimated to achieve 50% savings (relative to pre-retrofit) on a 12-unit building. The base scope was applied to the entire apartment complex, except for one 12-unit building which underwent the DER scope. A wide range of efficiency measures was applied to pursue this savings target for the DER building, including improvements/replacements of mechanical equipment and distribution systems, appliances, lighting and lighting controls, the building envelope, hot water conservation measures, and resident education. The results of this research build upon the current body of knowledge of multifamily retrofits. Towards this end, the research team has collected and generated data on the selection of measures, their estimated performance, their measured performance, and risk factors and their impact on potential measures.

Deep Residential Retrofits in East Tennessee  

SciTech Connect

Executive Summary Oak Ridge National Laboratory (ORNL) is furthering residential energy retrofit research in the mixed-humid climate of East Tennessee by selecting 10 homes and guiding the homeowners in the energy retrofit process. The homeowners pay for the retrofits, and ORNL advises which retrofits to complete and collects post-retrofit data. This effort is in accordance with the Department of Energy s Building America program research goal of demonstrating market-ready energy retrofit packages that reduce home energy use by 30 50%. Through this research, ORNL researchers hope to understand why homeowners decide to partake in energy retrofits, the payback of home energy retrofits, and which retrofit packages most economically reduce energy use. Homeowner interviews help the researchers understand the homeowners experience. Information gathered during the interviews will aid in extending market penetration of home energy retrofits by helping researchers and the retrofit industry understand what drives homeowners in making positive decisions regarding these retrofits. This report summarizes the selection process, the pre-retrofit condition, the recommended retrofits, the actual cost of the retrofits (when available), and an estimated energy savings of the retrofit package using EnergyGauge . Of the 10 households selected to participate in the study, only five completed the recommended retrofits, three completed at least one but no more than three of the recommended retrofits, and two households did not complete any of the recommended retrofits. In the case of the two homes that did none of the recommended work, the pre-retrofit condition of the homes and the recommended retrofits are reported. The five homes that completed the recommended retrofits are monitored for energy consumption of the whole house, appliances, space conditioning equipment, water heater, and most of the other circuits with miscellaneous electric loads (MELs) and lighting. Thermal comfort is also monitored, with temperature and humidity measured in all conditioned zones, attics, crawlspaces, and unconditioned basements. In some homes, heat flux transducers are installed on the basement walls to help determine the insulating qualities of the technologies and practices. EnergyGauge is used to estimate the pre-retrofit and post-retrofit home energy rating system (HERS) index and reduction in energy consumption and energy bill. In a follow-up report, data from the installed sensors will be presented and analyzed as well as a comparison of the post-retrofit energy consumption of the home to the EnergyGauge model of the post-retrofit home. Table ES1 shows the retrofits that were completed at the eight households where some or all of the recommended retrofits were completed. Home aliases are used to keep the homeowners anonymous. Some key findings of this study thus far are listed as follows. Some homeowners (50%) are not willing to spend the money to reach 30 50% energy savings. Quality of retrofit work is significantly variable among contractors which impact the potential energy savings of the retrofit. Challenges exist in defining house volume and floor area. Of the five homes that completed all the recommended retrofits, energy bill savings was not the main driver for energy retrofits. In no case were the retrofits cost neutral given a 15 year loan at 7% interest for the retrofit costs.

Building Retrofits: Energy Conservation and Employee Retention Considerations in Medium-Size Commercial Buildings  

E-Print Network (OSTI)

Commercial buildings are among the largest consumers of energy. In an attempt to control and reduce operating expenses, building owners and organizations leasing commercial space are pursuing energy efficiency measures to generate a higher return on investment. In this study, an extensive literature review is used to identify and discuss energy efficiency considerations for medium-size building owners and how savings from these measures may benefit organizations through employee satisfaction and retention. For the purpose of this study, the specific topics related to commercial building energy efficiency that were investigated include (1) outcomes of building retrofits (2) corporate social responsibility and performance; (3) performance of energy efficient buildings; (4) employee commitment, satisfaction productivity and organizational profitability; (5) green companies and employee attraction; (6) the cost of turnover. There is little literature specifically focused on the impact that energy efficient buildings have on medium-sized building owners and no literature that quantifies the financial benefits through a reduction in employee turnover or attrition. Facility managers of all building sizes will benefit from gaining (1) a broad understanding of the impact of energy efficiency measures on employees (2) the ability to articulate the impact of the buildings role on employee productivity, turnover and other HR related issues (3) the insight needed to contribute to strategic discussions within their organization about how facilities can benefit organizational profitability. This research does not attempt to claim or determine a causal relationship between energy efficiency and employee turnover however it does discuss issues that that could affect employee attrition.. Further research to determine this causality would benefit the study of energy efficiency and its total impact on organizations.

Measured Energy Savings from Retrofits Installed in Low-Income Housing in a Hot and Humid Climate  

E-Print Network (OSTI)

The Florida Solar Energy Center (FSEC) is metering energy use in a Habitat for Humanity housing development. The objective is to understand the way in which energy is used in low income housing and how it can be effectively reduced. The ten homes come from a conventional housing project built by in 1993 Habitat for Humanity in Homestead, Florida. The instrumentation was installed in the homes in July of 1994 with over three years of 15-minute data collected on all sites. Data were obtained on seven electrical end-uses (air conditioning, heating, hot water, dryer, range, refrigerator, washer/freezer) as well as total. Weather conditions were also monitored as well as interior comfort conditions (temperature and humidity) and hot water consumption and window ventilation status. Baseline field data from a year of monitoring from the ten homes allowed unique insight into how energy is used in low income housing and suggested where consumption might be reduced. In April of 1997, a series of detailed retrofits were applied to eight of the ten Habitat homes. These included solar water heaters installed in seven homes. In eight homes we retrofit light features to compact fluorescent types, repaired and sealed duct air distribution systems, cleaned refrigerator coils and installed low-flow showerheads. Since each of he associated energy end-uses (including hot water consumption) is metered, we are able to assess the relative performance of each of the retrofits. We also measured of air conditioner performance and house tightness. These audits revealed numerous problems, but low-evaporator coil air flow was discovered in all homes. The paper describes the retrofit installation, audit data collected and the impact on measured energy consumption. Preliminary economics are explored.

A Methodology for Baselining the Energy Use At Large Campus Utility Plants for the Purpose of Measuring Energy Savings from Energy Conservation Retrofits  

E-Print Network (OSTI)

The development of the energy services industry and the implementation of energy savings retrofits by energy services companies has increased the focus on the performance of energy saving retrofits. Energy savings measurement, though not an exact science, has been developing as well to ensure the benefit of a retrofit and to provide a level of assurance for the customers of energy services companies. This thesis presents a useful methodology for baselining campus utility usage using regression modeling techniques and measured daily data for the purpose of measuring energy savings. The methodology of this thesis improves upon previous regression modeling of individual buildings by extending commercial building energy usage models to an entire campus, modeling the operation of a central plant, and modeling central plant equipment performance with regression models. By adding equipment production layers, the user can more easily determine the cause of changes in the primary energy usage of a central plant. The case study for the application of the methodology of this thesis was the Texas A&M University main campus central plant. Useful results were obtained by utilizing one portion of the data to develop an energy usage baseline model and using the second portion of the data to validate the performance of the baseline model. Further development of the methodology could include the addition of an economic module and refinement of the model to incorporate the use of hourly data.

Review of Methods for Measuring and Verifying Savings from Energy Conservation Retrofits to Existing Buildings  

E-Print Network (OSTI)

The Measurement & Verification (M&V) process has evolved in the last 15 years to provide a high confidence approach for determining the resulting savings from a variety of retrofits and energy efficiency enhancements. M&V has a dual role. First, it quantifies the savings being obtained. Since the persistence of savings has been shown to decrease with time,1 long-term M&V provides data to make these savings sustainable. Second, M&V must be cost effective so that the cost of measurement and the analysis does not consume the savings.2, 3 Currently, a goal of about 5% of the savings per year has evolved as a preferred criteria for costing M&V, since the cost justification directly results from the savings obtained. The general procedure involves a selection of using a monthly billing analysis, a daily or hourly procedure, a component isolation analysis, or a calibrated simulation. Calibrated simulations are usually expensive and difficult to complete.

Energy Implications of Retrofitting Retail Sector Rooftop Units with Stepped-Speed and Variable-Speed Functionality  

Science Conference Proceedings (OSTI)

Commercial retailers understand that retrofitting constant-speed RTU fan motors with stepped- or variable-speed alternatives could save significant energy in most U.S. climate zones. However, they lack supporting data, both real-world and simulation based, on the cost effectiveness and climate zone-specific energy savings associated with this measure. Thus, building managers and engineers have been unable to present a compelling business case for fan motor upgrades to upper management. This study uses whole-building energy simulation to estimate the energy impact of this type of measure so retailers can determine its economic feasibility.

Retrofit of waste-to-energy facilities equipped with electrostatic precipitators. Volume I: Report  

Science Conference Proceedings (OSTI)

To help lower the cost of compliance for waste-to-energy facilities, a retrofit technology using water spray temperature reduction combined with dry acid gas control reagent and powdered activated carbon [PAC] injection was tested in November, 1995 as part of an American Society of Mechanical Engineers' [ASME] Center for Research and Technology Development [CRTD] effort supported in part by the Department of Energy's National Renewable Energy Laboratory [NREL] and directed by the ASME Research Committee on Industrial and Municipal Waste. 2,000 mg/dsm{sup 3} @ 7% O{sub 2} (150 lb/hr) of trona (a natural sodium sesquicarbonate ore) injected through a rapid dispersion lance successfully controlled more than 50 percent of the acid gases. This should let facilities under 250 TPD meet the small plant guidelines for acid gas control. Various levels of PAC were injected along with the trona. 300 mg/dsm{sup 3} 7% O{sub 2} of PAC provides a comfortable margin between the emissions limitations achieved and both large and small plant regulatory guidelines for tetra- through octachlorinated dibenzo-p-dioxins and dibenzofurans [PCDD/F] and mercury when the ESP is operated below 350 F. Bi-fluid nozzles were used to spray finely atomized water between the economizer outlet and ESP inlet to maintain temperatures in the desired 300-350 F range. Particulate and metals emissions limitations were met by this 400 ft{sup 2}/1,000 acft{sup 2} specific collector area [SCA], 3-field ESP. Both the water sprays and PAC improved ESP performance. The demonstration was successful. With dry PAC, acid gas reagent injection, and temperature reduction, MWC emissions guidelines for facilities smaller than 250 TPD can be reliably met. Everything except the large facilities SO{sub 2} and HCl guideline emissions limitations was achieved. Better acid gas control should be achievable with more reagent addition if the ESP is efficient enough to avoid violating particulate limits.

The use of energy management and control systems for retrofit performance monitoring in the LoanSTAR program. Final report  

SciTech Connect

Monitoring of building energy consumption, operation, and weather variables are important parts of retrofit evaluation projects. However, effective monitoring can be quite expensive. In this report, we investigate the feasibility of using a building`s existing energy management and control system (EMCS) for gathering some or all of this required data, rather than installing dedicated data-logging equipment. Three case studies in the Texas LoanSTAR retrofit monitoring program were used to explore the current applicability of existing EMCSs for monitoring, and to identify areas requiring additional development It was found that data could be retrieved in each case; without installing any additional hardware or software in two of the three sites, and with the addition of only a few sensors and a minor software modification in the third. However, the process of using the EMCS for monitoring was inconvenient in several respects. It was determined that the process could be greatly simplified if EMCS manufacturers ensured that their software averaged data over an hourly interval and reliably reported them at the end of each hour, used concise and consistent formats for requesting and reporting the data, and provided a simple means of displaying or transmitting the data.

The Cutting Edge: Progress in Residential Retrofit The Cutting Edge: Progress in Residential Retrofit A geographic representation of saturations of ceiling fans based on data from the RASSes. White areas indicate a lack of data for that region. Many utilities survey their customers to learn more about the buildings and the occupants in their service areas. These surveys-usually called "residential appliance saturation surveys," or RASSes-ask for the number and types of appliances present, the number of people living in the home, and sometimes personal information. The RASSes are also used to collect information about the presence of conservation measures such as wall and ceiling insulation, weatherstripping, multipane windows, and water flow restrictors. Building Energy Analysis Group researchers Alan Meier and Brian Pon gathered RASSes

Estimation of Energy Baseline by Simulation for On-going Commissioning and Energy Saving Retrofit  

E-Print Network (OSTI)

This paper proposes a method of estimating the adjusted energy baseline using simulation models, which can calculate the energy baseline with various conditions, such as conditions of weather, occupancy and equipment operations. Especially, this paper reveals what detailed data the calibration of the model needs and the change of accuracy caused by different calibration data. Using the operational data of a middle-scale office building in Osaka Japan, the simulation accuracies of three models, which are calibrated using monthly energy consumptions of whole building (Level 1), monthly energy consumptions of subsystems (Level 2) and the detailed operational data of equipments (Level 3) respectively, are compared. The result shows that the differences of daily-integrated energy consumptions between measured value and simulated value using the model of Level 1 and 2 are not much different. The model of Level 3 is about 3% more accurate than the model of Level 1 and 2.

Opportunities for Energy Conservation and Improved Comfort From Wind Washing Retrofits in Two-Story Homes - Part I  

E-Print Network (OSTI)

Wind washing is a general term referring to diminished thermal control caused by air movement over or through a thermal barrier. The primary focus of this paper is towards a specific type of wind washing where wind can push attic air into the floor cavity between first and second stories of the home through ineffective (or missing) air barriers separating attic space from the floor cavity. A second type of wind washing studied in this project involved insulation batts on knee walls where space between the batts and the wall board allowed air movement against the gypsum wall board. During hot weather, the first type of wind washing pushes hot air into the floor cavity (between the first and second stories) thereby heating ceiling, floor, and interior wall surfaces (see Figures 1 and 2). Condensation may occur on cold supply duct surfaces within the floor cavity resulting in ceiling moisture damage. In cold climates, cold air from wind washing can chill surfaces within the interior floor space and result in frozen water pipes. Through the summer of 2009, a field study tested thirty-two two-story homes and found significant wind washing potential in 40% of the homes. Part I of this paper will highlight the evaluation methods used and the extent of wind washing found in this study. Repairs and energy monitoring were completed in six of these homes to evaluate retrofit methods and cost effectiveness of retrofit solutions. These results are discussed in Part II of this paper.

Measuring retrofit savings in commercial buildings with pre-retrofit utility billing data and post-retrofit sub-metered data  

E-Print Network (OSTI)

Methodologies to measure energy and dollar savings resulting from energy conserving retrofits in commercial buildings when both pre-retrofit and post-retrofit monitored data are available at an hourly or daily level have already been developed by several researchers. However there are many occasions when hourly or daily energy consumption data are available only for the post-retrofit period. This thesis presents a methodology for measuring retrofit savings on such occasions by establishing a pre-retrofit baseline model of energy consumption based on pre-retrofit monthly utility billing data and sub-metered daily or hourly post-retrofit data. The procedure consists of two basic parts. The first part normalizes energy use for temperature dependency using post-retrofit sub-metered hourly data, the second part accounts for scheduling effects and develops a pre-retrofit baseline model using pre-retrofit utility bills. In this way, the method explicitly accounts for both scheduling and weather effects in developing a baseline for pre-retrofit energy consumption. The methodology is first tested with data from a LoanSTAR site where both pre- and post-retrofit data are available. It is then illustrated with two other LoanSTAR sites where only post-retrofit sub-metered data and pre-retrofit monthly utility billing data are available. This thesis also employs the direct utility bill comparison method to measure retrofit savings, and extends it to include a simple temperature comparison and compares results on a monthly and annual basis with the method developed herein.

Rehabilitating missing energy use and weather data when determining retrofit energy savings in commercial buildings  

E-Print Network (OSTI)

This thesis evaluates four methods for rehabilitating short periods of missing data. Single variable regression, polynomial models, Lagrange interpolation, and linear interpolation models are developed, demonstrated, and used to fill 1-6 hour gaps in weather data, heating data and cooling data for commercial buildings. The methodology for comparing the performance of the four different methods for filling data gaps uses 11 one-year data sets to develop different models and fill over 250,000 "pseudo-gaps'' which are created by assuming data is missing and then comparing the "filled'' values with the measured values. The major findings may be summarized as follows: 1. It was also found that different data types have different gap frequency distributions. Data gaps of 1-6 hours cover all missing NWS temperature and dew point data. One to six hour gaps also cover 50-70% of the total missing LO-STAR temperature and humidity data, and 50-70% of total missing LO-STAR energy use such as cooling, heating, motor control use and electricity data. 2. The polynomial model and the linear interpolation model are comparable and more accurate than other models. The linear interpolation model is slightly better than the polynomial model for filling both missing weather data gaps and missing cooling data gaps. The least accurate is the Lagrange model, particularly as the length of the data gap increases. The single variable regression (SVR) method can not deal with missing weather data due to the pattern of weather data. Based on these findings, a polynomial model with hour-of-day as an independent variable and a linear interpolation model are recommended to fill 1-6 hour data gaps in cooling, heating and weather data.

Retrofit Air Preheat Economics  

E-Print Network (OSTI)

Retrofit air preheat systems are the most reliable and efficient means to effect significant energy conservation for large existing industrial furnaces. Units can be quickly installed without a lengthy shutdown, and the furnace efficiency can be increased to a range of 89% to 92%. The economic justification for the addition of this equipment is presented in new total investment curves and simple payout curves for a range of fuel cost. This will enable the owner to quickly determine the preliminary feasibility and conceptual requirements for his project before proceeding with more vigorous work.

EMCS Retrofit Analysis - Interim Report  

SciTech Connect

This report presents the interim results of analyses carried out in the Phillip Burton Federal Building in San Francisco from 1996 to 1998. The building is the site of a major demonstration of the BACnet communication protocol. The energy management and control systems (EMCS) in the building were retrofitted with BACnet compatible controllers in order to integrate certain existing systems on one common network. In this respect, the project has been a success. Interoperability of control equipment from different manufacturers has been demonstrated in a real world environment. Besides demonstrating interoperability, the retrofits carried out in the building were also intended to enhance control strategies and capabilities, and to produce energy savings. This report presents analyses of the energy usage of HVAC systems in the building, control performance, and the reaction of the building operators. The report does not present an evaluation of the performance capabilities of the BACnet protocol. A monitoring system was installed in the building that parallels many of the EMCS sensors and data were archived over a three-year period. The authors defined pre-retrofit and post-retrofit periods and analyzed the corresponding data to establish the changes in building performance resulting from the retrofit activities. The authors also used whole-building energy simulation (DOE-2) as a tool for evaluating the effect of the retrofit changes. The results of the simulation were compared with the monitored data. Changes in operator behavior were assessed qualitatively with questionnaires. The report summarizes the findings of the analyses and makes several recommendations as to how to achieve better performance. They maintain that the full potential of the EMCS and associated systems is not being realized. The reasons for this are discussed along with possible ways of addressing this problem. They also describe a number of new technologies that could benefit systems of the type found in the Philip Burton Federal Building.

Florida house aglow with lighting retrofit  

SciTech Connect

In a residential lighting retrofit, how much energy can be saved with current technology? The Florida Solar Energy Center decided to find out by retrofitting every lamp in a Miami home. Most lighting studies focus on average lighting energy use or on how much energy can be saved by retrofitting large numbers of homes. However, the Florida Solar Energy Center (FSEC) was interested in finding out how much lighting energy we could save in a single house. One house with high utility bills and extensive interior lighting was picked, throughly monitored, and retrofitted every light possible. The study also helped determine what sort of monitoring is most useful, and how residents respond to efficient lighting. 1 fig., 2 tabs.

A local law firm upgraded one floor of their offices in the Wells Fargo Center (center) in Denver as part of Commercial Building Partnerships. Renovation, retrofit and refurbishment of existing buildings represent an opportunity to upgrade the energy performance of commercial building assets for their ongoing life. Often retrofit involves modifications to existing commercial buildings that may improve energy efficiency or decrease energy demand. In addition, retrofits are often used as opportune time to install distributed generation to a building. Energy efficiency retrofits can reduce the operational costs, particularly in older buildings, as well as help to attract tenants and gain a market edge.

Assessment of Solar Energy Conversion Technologies-Application of Thermoelectric Devices in Retrofit an Office Building  

E-Print Network (OSTI)

Thermo electric (TE) devices offer an opportunity to introduce renewable energy into existing and new buildings. TE devices harvest energy from the temperature differential between the hot and cold side of a semiconductor material. In this study, the feasibility of integration of TE devices using the model of a generic enclosure will be explored. Some of these applications will involve the use of these devices as heat exchangers. However, these devices will be examined for their use in harvesting energy to provide the electric service for an office. Since demanded energy for some electronic devices can be generated directly, provided energy has the potential to take those loads off from the distribution. Besides, generated electricity expected to be replaced a greater amount of grid electricity for the periods when TE is generating. This paper represents a critical step for performing an analysis of using the proposed TE system in an office.

Housing Stock Characterization Study: An Innovative Approach to Measuring Retrofit Impact  

Science Conference Proceedings (OSTI)

A residential energy efficiency retrofit loan program depends on a self-sustaining finance option and optimized retrofit measures that recoup their unsubsidized costs through energy bill savings alone within the useful life of the retrofit. A first step in evaluating retrofit options is to measure and verify their energy savings. This report evaluates Orlando Utilities Commission (OUC) residential energy-efficiency demand side management (DSM) programs to assess their relative energy and economic performance.

Retrofit of Existing Residential Building: a Case Study  

E-Print Network (OSTI)

There are about 42 billion square meters of existing buildings in China. The energy efficiency of existing buildings directly relates to the energy consumption of the building sector. The retrofit of existing residential building began in the 1990s in Heilongjiang. The Sino-Canada demonstration project and Sino-France demonstration project of retrofitting existing residential buildings were carried out in 1997 and 2004, respectively. The retrofit method and energy conservation potential of the envelope and heating system of northern existing buildings are analyzed in this paper, combining the experiences of retrofitting existing residential buildings in Heilongjiang. The software was compiled to aid the design of the envelope retrofit in Heilongjiang and to analyze the working situation in existing residential building heating systems. The imbalance of the indoor temperature and the quantity of heating loss from opening the window in different retrofit projects are presented. The emphasis on energy efficiency retrofit of the envelope of existing residential buildings should be placed on the wall in northern region. It is possible to reduce about 50 percent of energy consumption of buildings by insulating the wall. The external insulation is suitable for retrofitting existing buildings, and the moisture transfer should be considered at the same time. To insure actual reduction in energy consumption, the heating system should be retrofitted when the envelope is insulated.

Empirical impact evaluation of the energy savings resulting from BPA's Stage II irrigation system retrofit program: Final report  

SciTech Connect

This report documents the results of an evaluation of the impacts on irrigation system energy consumption of conservation measures installed under the Bonneville Power Administration's Stage II retrofit program. Historical billing data and other farm records provided the basis for this evaluation. A number of different statistical techniques were used to estimate the actual energy savings resulting from the Stage II conservation measures. Results of the study reveal that the methodology used in predicting energy savings resulting from the Stage II program is accurate. The basis for energy savings predictions in the Stage II program are changes in brake horsepower, and, in this study, a 1% change in brake horsepower was found to result in slightly more than a 1% change in energy consumption. Overall, Stage II program conservation measures were found to reduce irrigation system energy use by an average of 34%. The average costs of obtaining these savings were 6 mills (.6 cents) per kWh saved.

Result of recent weatherization retrofit projects  

Science Conference Proceedings (OSTI)

Pacific Gas and Electric (PG and E) and the Bonneville Power Administration (BPA) have conducted studies in their respective service areas in order to evaluate the cost-effectiveness of certain conservation retrofits. Twenty houses in Walnut Creek, California, underwent an infiltration reduction program, similar to house doctoring. Ten of these houses also received additional contractor-installed measures. BPA retrofitted 18 houses at its Midway substation in central Washington. Retrofits made to the houses included: attic and crawlspace insulation, foundation sill caulking, storm windows and doors, increased attic ventilation, and infiltration reduction. Energy consumption and weather data were monitored before and after each set of retrofits in both projects. Leakage measurements were made by researchers from the Energy Efficient Buildings Program using blower door fan pressurization, thereby allowing calculation of heating season infiltration rates. An energy use model correlating energy consumption with outside temperature was developed in order to determine improvements to the thermal conductance of the building envelope as a result of the retrofits. Energy savings were calculated based on the results of the energy use model. As a check on these findings, the Computerized Instrumented Residential Audit (CIRA) load calculation program developed at Lawrence Berkeley Laboratory provided a theoretical estimate of the savings resulting from the retrofits. At Midway, storm windows and doors were found to save the most energy. Because the Midway houses were not very leaky at the beginning of the experiment, the infiltration reduction procedures were less effective than expected. In the Walnut Creek project, the infiltration reduction procedures did decrease the leakiness of the test houses, but the effect upon energy savings was not great.

Cold climate foundation insulation retrofit performance  

SciTech Connect

The effectiveness of foundation insulation retrofits in 15 Minnesota houses was evaluated using a before-after experimental method. Nine houses received interior retrofits; six, exterior retrofits. Foundation air leaks were sealed before the preretrofit heating season to control for inadvertent sealing during retrofit. Basement heating supply and return registers were closed in most houses for the 21-month monitoring period, and for all houses the basement was an uncontrolled zone without a thermostat. Homeowners recorded gas and electricity meter readings and furnace and water heater on-times weekly. A load vs. outdoor temperature was used to evaluate changes in energy use. The average whole-house energy savings for the interior and exterior cases were 92 and 24 therm per year, or 7.9% (range - 0.6% to 17.8%) and 3.0% (range -2.9% to 8.3%), respectively. Minimum payback periods for the interior and exterior cases were 12 and 37 years, respectively. For all houses the basement temperature increased between the pre- and post-retrofit periods, and all homeowners reported increased comfort in their basements. Average measured savings were about one-third of those predicted. The results show that the application of insulation in an uncontrolled zone produces highly variable results and has the principal effect of increasing the temperature and comfort of the basement rather than producing cost-effective whole-house energy savings.

Greenbuilt Retrofit Test House Final Report  

SciTech Connect

The Greenbuilt house, is an all-electric, 1980's era home in the eastern Sacramento suburb of Fair Oaks that was retrofit by Greenbuilt Construction as part of Sacramento Municipal Utility District's (SMUD) Energy Efficient Remodel Demonstration (EERD) Program. The project was a joint effort between the design-build team at Greenbuilt Construction, led by Jim Bayless, SMUD and their project manager Mike Keesee, and the National Renewable Energy Laboratory (NREL). The goal of the Energy Efficient Remodel Demonstration program is to work with local builders to renovate homes with cost-effective energy efficient retrofit measures. The homes remodeled under the EERD program are intended to showcase energy efficient retrofit options for homeowners and other builders. The Greenbuilt house is one of five EERD projects that NREL has supported. NREL's main role in these projects is to provide energy analysis and to monitor the home's performance after the retrofit to verify that the energy consumption is in line with the modeling predictions. NREL also performed detailed monitoring on the more innovative equipment included in these remodels, such as an add-on heat pump water heater.

ASHRAE's Proposed Guideline 14P for Measurement of Energy and Demand Savings: How to Determine What Was Really Saved by the Retrofit  

E-Print Network (OSTI)

ASHRAE has recently completed the development of Guideline 14 to fill a need for a standard set of energy (and demand) savings calculation procedures. Guideline 14 is intended to be a guideline that provides a minimum acceptable level of performance in the measurement of energy and demand savings from energy management projects applied to residential, commercial or industrial buildings. Such measurements can serve as the basis for commercial transactions between Energy Service Companies (ESCOs) and their customers, or other energy conservation providers that rely on energy savings as the basis for repayment of the costs of the retrofit. When applied properly, ASHRAE Guideline 14 is expected to provide adequate assurance for the payment of services by allowing for well specified measurement methods that provide reasonably accurate savings calculations. ASHRAE Guideline 14 may also be used by governments to calculate pollution reductions from energy efficiency activities. Since Guideline 14 is intended to be applied to an individual building, or a few buildings served by a utility meter, large scale utility energy conservation programs, such as those involving statistical sampling, are not addressed by the current version of Guideline 14. Furthermore, metering standards and procedures for calculating savings from modifications to major industrial process loads are also not covered. This paper presents an overview of the measurement methods contained in ASHRAE Guideline 14 , including a discussion about how they were developed, and their intended relationship with other national protocols for measuring savings from energy conservation programs, such as the USDOE's International Performance Measurement and Verification Protocols (IPMVP).

Predicted Versus Actual Savings for a Low-Rise Multifamily Retrofit in Boulder, Colorado  

SciTech Connect

To determine the most cost-effective methods of improving buildings, accurate analysis and prediction of the energy use of existing buildings is essential. However, multiple studies confirm that analysis methods tend to over-predict energy use in poorly insulated, leaky homes and thus, the savings associated with improving those homes. In NREL's report titled 'Assessing and Improving the Accuracy of Energy Analysis of Residential Buildings,' researchers propose a method for improving the accuracy of residential energy analysis methods. A key step in this process involves the comparisons of predicted versus metered energy use and savings. In support of this research need, CARB evaluated the retrofit of a multifamily building in Boulder, CO. The updated property is a 37 unit, 2 story apartment complex built in 1950, which underwent renovations in early 2009 to bring it into compliance with Boulder, CO's SmartRegs ordinance. Goals of the study were to: 1) evaluate predicted versus actual savings due to the improvements, 2) identify areas where the modeling assumptions may need to be changed, and 3) determine common changes made by renters that would negatively impact energy savings. In this study, CARB seeks to improve the accuracy of modeling software while assessing retrofit measures to specifically determine which are most effective for large multifamily complexes in the cold climate region. Other issues that were investigated include the effects of improving building efficiency on tenant comfort, the impact on tenant turnover rates, and the potential market barriers for this type of community scale project.

An Exploration of Wall Retrofit Best Practices  

SciTech Connect

A series of experiments were performed to examine wall retrofit options including replacing the cladding, adding insulation under the cladding, and multiple sealing methods that can be used when installing replacement windows in well-built or loosely-built rough openings. These experiments included thermal measurements in a hot box and air-leakage measurements. The retrofit claddings considered included wood-lap siding, vinyl siding, and vinyl siding with an integrated and formed foam insulation. Retrofit insulations included expanded and extruded polystyrene and foil-faced polyisocyanurate in various thicknesses. Air sealing methods for replacement windows included traditional caulking, exterior trim variations, loose-fill fiberglass, low-expansion foam, self-expanding foam inserts, and specialty tape. Results were applied to a model to estimate whole-house energy impacts for multiple climates.

Continuous Commissioning: A Valuable Partner to Retrofit Projects  

E-Print Network (OSTI)

Continuous Commissioning (CC) or HVAC system optimization is not only a valuable stand-alone energy saving measure for commercial buildings, but it is also an important escort solution to retrofit projects. Energy retrofit projects typically achieve projected savings. But in cases where savings goals are not being met, optimizing HVAC system performance can be the difference in an underachieving versus a successful project. This paper presents a real-world study of pairing a CC project with an energy retrofit in a 107,000 square foot hospital building. Applying the CC strategy to an underperforming retrofit, projected energy savings were achieved and even increased. Additionally, by increasing supply air capacity, patients, staff and visitors now enjoy improved comfort conditions. This paper also explores the working relationship between an ESCO and a university research laboratory, whose combined efforts led to this remarkable turn around.

Homeowner Best Practices Guide for Residential Retrofits  

SciTech Connect

This best practices guide for HV AC system retrofits is aimed at homeowners who want guidance on upgrading their heating, cooling and ventilation (HVAC) systems and integrating these upgrades with other changes to their home. It has been developed around the idea of having packages of changes to the building HV AC system and building envelope that are climate and house construction dependent. These packages include materials procedures and equipment, and are designed to remove some of the guesswork when selecting a builder, contractor, or installer. The packages are not meant to be taken as rigid requirements - instead they are systems engineered guidelines that form the basis for energy efficient retrofits. Similar approaches have been taken previously for new construction, where a systems engineering approach has been used to develop extremely energy-efficient homes that are comfortable safe and durable, and often cost less than standard construction. This approach is best epitomized by the Building America program, whose partners have built thousands of residences throughout the U.S. using these principles. The differences between retrofitting and new construction tend to limit the changes one can make to a building, so these packages rely on relatively simple and non-intrusive technologies and techniques. The retrofits also focus on changes to a building that will give many years of service to the occupants. Another key aspect of these best practices is that we need to know how a house is working so that we know what parts have the potential for improvement. To do this we have put together a set of simple tests that a homeowner can perform on their own together with checklists and questionnaires. The measured test results, observations and homeowner answers to questions are used to direct us towards the best retrofits applicable to each individual house. The retrofits will depend on the current condition of the building envelope and HV AC system, the local climate, the construction methods used for the house, and the presence of existing energy saving systems and/or materials. This is just like a doctor referring a patient for blood tests or x-rays before actually performing surgery. This way the doctor can be sure that he does the right thing. To take this analogy further - we can borrow from the medical profession and say that the first thought when retrofitting a house is to do no harm, i.e., do not make changes that could make the house worse to live in.

Post-Retrofit Residential Assessments  

SciTech Connect

This study examined a range of factors influencing energy consumption in households that had participated in residential energy-efficiency upgrades. The study was funded by a grant from the U.S. Department of Energys Pacific Northwest National Laboratory and was conducted by faculty and staff of Portland State University Center for Urban Studies and Department of Economics. This work was made possible through the assistance and support of the Energy Trust of Oregon (ETO), whose residential energy-efficiency programs provided the population from which the sample cases were drawn. All households in the study had participated in the ETO Home Performance with Energy Star (HPwES) program. A number of these had concurrently pursued measures through other ETO programs. Post-retrofit energy outcomes are rarely investigated on a house-by-house basis. Rather, aggregate changes are ordinarily the focus of program impact evaluations, with deviation from aggregate expectations chalked up to measurement error, the vagaries of weather and idiosyncrasies of occupants. However, understanding how homes perform post-retrofit on an individual basis can give important insights to increase energy savings at the participant and the programmatic level. Taking a more disaggregated approach, this study analyzed energy consumption data from before and after the retrofit activity and made comparisons with engineering estimates for the upgrades, to identify households that performed differently from what may have been expected based on the estimates. A statistical analysis using hierarchal linear models, which accounted for weather variations, was performed looking separately at gas and electrical use during the periods before and after upgrades took place. A more straightforward comparison of billing data for 12-month periods before and after the intervention was also performed, yielding the majority of the cases examined. The later approach allowed total energy use and costs to be assessed but did not account for weather variation. From this statistical analysis, 18 study participants were selected and interviewed. The participants completed an in-home interview covering a range of topics, including changes in occupancy and additional changes to the homes that may have affected energy use. The goal of the interviews was to identify factors that may have contributed to unusual energy performance. These factors were identified by their frequency of occurrence in outperforming or underperforming homes, or simply by identifying factors that had the largest impact on overall savings. The motivations and levels of satisfaction with the outcomes of the upgrades were covered in detail, as well as extensive discussions of behaviors pertaining to thermal control, lighting, water, and appliance use. Most of cases studied achieved substantial energy savings, although it was more common for the projected savings to be greater than the demonstrated savings. Two factors that played a very large role in savings variation were 1) changes in occupancy and 2) fenestration improvements outside of the incentive programs. Motivation for pursuing the upgrades (e.g., environmental sustainability vs. comfort or cost savings) did not seem to play any role in achieving savings. Participants generally were more concerned with maintaining aesthetics through lighting than comfort through heating or cooling. They also seemed more likely to turn the lights off when leaving a room than to turn the heat off when leaving the home.

Comparison of Home Retrofit Programs in Wisconsin  

SciTech Connect

To explore ways to reduce customer barriers and increase home retrofit completions, several different existing home retrofit models have been implemented in the state of Wisconsin. This study compared these programs' performance in terms of savings per home and program cost per home to assess the relative cost-effectiveness of each program design. However, given the many variations in these different programs, it is difficult to establish a fair comparison based on only a small number of metrics. Therefore, the overall purpose of the study is to document these programs' performance in a case study approach to look at general patterns of these metrics and other variables within the context of each program. This information can be used by energy efficiency program administrators and implementers to inform home retrofit program design. Six different program designs offered in Wisconsin for single-family energy efficiency improvements were included in the study. For each program, the research team provided information about the programs' approach and goals, characteristics, achievements and performance. The program models were then compared with performance results -- program cost and energy savings -- to help understand the overall strengths and weaknesses or challenges of each model.

Bayesian Analysis of Savings from Retrofit Projects  

SciTech Connect

Estimates of savings from retrofit projects depend on statistical models, but because of the complicated analysis required to determine the uncertainty of the estimates, savings uncertainty is not often considered. Numerous simplified methods have been proposed to determine savings uncertainty, but in all but the simplest cases, these methods provide approximate results only. The objective of this paper is to show that Bayesian inference provides a consistent framework for estimating savings and savings uncertainty in retrofit projects. We review the mathematical background of Bayesian inference and Bayesian regression, and present two examples of estimating savings and savings uncertainty in retrofit projects. The first is a simple case where both baseline and post-retrofit monthly natural gas use can be modeled as a linear function of monthly heating degree days. The Efficiency Valuation Organization (EVO 2007) defines two methods of determining savings in such cases: reporting period savings, which is an estimate of the savings during the post-retrofit period; and normalized savings, which is an estimate of the savings that would be obtained during a typical year at the project site. For reporting period savings, classical statistical analysis provides exact analytic results for both savings and savings uncertainty in this case. We use Bayesian analysis to calculate reporting period savings and savings uncertainty and show that the results are identical to the analytical results. For normalized savings, the literature contains no exact expression for the uncertainty of normalized savings; we use Bayesian inference to calculate this quantity for the first time, and compare it with the result of an approximate formula that has been proposed. The second example concerns a problem where the baseline data exhibit nonlinearity and serial autocorrelation, both of which are common in real-world retrofit projects. No analytical solutions exist to determine savings or savings uncertainty in this situation, but several simplified formulas have been proposed. We model the data using a 5-parameter model with first-order autoregressive errors, and use Bayesian inference to develop distributions for the model parameters and for the reporting period savings, which allows us to determine the savings uncertainty. We find the energy savings to be about 5% lower than the result obtained by ignoring the autocorrelation. In addition, the Bayesian analysis finds the savings uncertainty to be narrower than the approximate uncertainty calculated using the simplified formula. These results show that Bayesian inference can be used to determine savings and savings uncertainty for a wide variety of real-world problems.

As a part of the Energy Cost Reduction Measure (ECRM) retrofit program, funded by LoanSTAR, the U.T. Arlington site was granted a $2 million loan to implement an energy-saving lighting retrofit in 20 classroom buildings on the campus. The original Audit Report for the site, completed in 1991, recommended a lighting retrofit that included delamping, relamping with high efficiency lamps, the installation of high efficiency electronic ballasts, and the installation of specular reflectors. However, if the retrofit could be implemented without the use of specular reflectors, then a considerable amount of investment capital would be saved.

Retrofit Savings for Brazos County  

E-Print Network (OSTI)

This report presents the energy and dollar savings for the period May 2000 - April 2001 for 10 of the Brazos County facilities that have been retrofit. The electricity use saved was 555,170 kWh and the demand was 1062 kW, which is equivalent to a $31,743 dollars savings, $24,650 from electricity use and $7,093 from the electric demand. These savings represent a 60.8% of the audit-estimated savings and a 93.7% of the audit-estimated savings if just the positive one were taken in account. The savings have improved somewhat from the previous report that included the billing periods for January to August 1999. The savings for the earlier period were 48.0% of the audit-estimated savings that means compared with 60.8% for the current period. In general has been an improvement in the energy saving in most of the facilities. The cases where are observed negative savings are the Minimum Security Jail, where is known that the area was increased significantly, the Arena Hall, where the modeling can be normalized due to kind of use of this facility, and the Road and bridges Shop, which looks to be operated more time in this period.

This article for HomeEnergy Magazine, a trade magazine on energy efficient home construction, retrofitting, remodeling, and research, describes retrofit projects by Grupe Homes of Sacramento, California, a production builder who has worked with DOE's Building America program on energy-efficient home demonstration projects. In this project, The article is a case study of Grupe's decision to enter the energy efficient remodeling market when new home sales lagged due to the economic slowdown starting in late 2007. The article also describes an energy-efficient retrofit of of a 22-year-old, 3-bedroom home in Californias Central Valley done in 2009 by Grupe. The home is Grupe's first retrofit and was done according to the criteria of Home Performance with ENERGY STAR, a national program from the EPA and DOE that promotes a comprehensive, whole-house approach to making energy-efficiency improvements. Grupe's staff were trained through the California Building Performance Contractors Association and passed the Building Performance Institute test to learn how to conduct extensive energy audits of existing houses as well to perform the energy efficient retrofits. In the retrofit home, they did extensive air sealing, replaced and added insulation, and replaced inefficient HVAC equipment and leaky can lights. They cut air leakage from 2478 to 1115 cfm 50, a 55% reduction. A Building America case study on this project was distributed at the EEBA (Energy and Environmental Building Alliance) Annual Conference in Denver, Colorado, Sept 28-30, 2009. The Home Energy article was published in the March/April 2010 issue.

Industrial Retrofits are Possible  

E-Print Network (OSTI)

Ontario is the industrial heartland of Canada and more than 80% of its energy comes from Canadian sources with the remainder from the neighbouring U.S. states. Because of the ever increasing demand for energy relating to increased economic activity, the provincial government's major energy priority is efficiency. In April of 1987, the provincial government initiated a program to assist industrial energy users to reduce their energy usage. This program was designed to concentrate on an in-depth analysis of the complete operations of industrial plants with the analyses being performed by specialist, private sector, engineering consultants. The program is in 3 phases providing an Ontario industrial plant with an Energy Analysis, a Feasibility Analysis Grant and a Project Engineering Design Grant. In this presentation, the author will outline the results of the program to date and will attempt to share with the audience the individual case experiences. Since the program's start, the Ontario Ministry of Energy has completed over 320 energy analyses of industrial plants which had combined energy bills of over $420 million. The potential annual energy savings identified were over $40 million or 9.51%. Electricity and natural gas are the major fuels used by Ontario industries and our surveys to date have shown savings of 6% in electricity and 11% in natural gas. Over the first two years of the program, individual plants have or are intending to implement more than half of the energy analysis recommendations.

Retrofitting analysis of integrated bio-refineries  

E-Print Network (OSTI)

A bio-refinery is a processing facility that produces liquid transportation fuels and/or value-added chemicals and other products. Because of the dwindling resources and escalating prices of fossil fuels, there are emerging situations in which the economic performance of fossil-based facilities can be enhanced by retrofitting and incorporation of bio-mass feedstocks. These systems can be regarded as bio-refineries or integrated fossilbio- refineries. This work presents a retrofitting analysis to integrated bio-refineries. Focus is given to the problem of process modification to an existing plant by considering capacity expansion and material substitution with biomass feedstocks. Process integration studies were conducted to determine cost-effective strategies for enhancing production and for incorporating biomass into the process. Energy and mass integration approaches were used to induce synergism and to reduce cost by exchanging heat, material utilities, and by sharing equipment. Cost-benefit analysis was used to guide the decision-making process and to compare various production routes. Ethanol production from two routes was used as a case study to illustrate the applicability of the proposed approach and the results were bio-refinery has become more attractive then fossil-refinery.

Retrofiting survivability of military vehicles  

SciTech Connect

In Iraq the terrain was such that vehicles could be distributed horizontally, which reduced the effectiveness of mines. In the mountainous terrain of Pakistan and Afghanistan vehicles are forced to use the few, passable roads, which are dirt and easily seeded with plentiful, cheap, intelligent mines. It is desirable to reduce the losses to such mines, preferably by retrofit means that do not greatly increase weight or cost or reduce maneuverability. V-bottom vehicles - A known approach to reducing vulnerability is the Buffalo, a large vehicle developed by South Africa to address mine warfare. It has large tires, high axles, and a reinforced, v-shaped bottom that deflects the blast from explosions below. It is developed and tested in combat, but is expensive and has reduced off-road mobility. The domestic MRAP has similar cost and mobility issue. The addition of v-shaped blast deflectors to vehicles such as Humvees could act much as the deflector on a Buffalo, but a Humvee is closer to the ground, so the explosive's expansion would be reduced. The deflector would also reduce a Humvee's clearance for rough terrain, and a deflector of adequate thickness to address the blast by itself could further increase cost and reduce mobility. Reactive armor is developed and has proven effective against shaped and explosive charges from side or top attack. It detects their approach, detonates, and defeats them by interfering with jet formation. If the threat was a shaped charge from below, they would be a logical choice. But the bulk of the damage to Humvees appears to be from the blast from high explosive mines for which the colliding shock from reactive armor could increase that from the explosive. Porous materials such as sand can strongly attenuate the kinetic energy and pressure of a strong shock. Figure 1 shows the kinetic energy (KE), momentum (Mu), velocity (u), and mass (M) of a spherically expanding shock as functions of radius for a material with a porosity of 0.5. Over the range from 0.5 to 4.5 cm the shock KE is attenuated by a factor of {approx}70, while its momentum is changed little. The shock and particle velocity falls by a factor of 200 while the mass increases by a factor of 730. In the limit of very porous media u {approx} 1/M, so KE {approx} 1/M, which falls by a factor of {approx}600, while momentum Mu does not change at all. Figure 2 shows the KE, Mu, u, and M for a material with a porosity of 1.05, for which the KE changes little. In the limit of media of very low porosity, u {approx} 1/{radical}M, so KE is constant while Mu {approx} {radical}M, which increases by a factor of 15. Thus, if the goal is to reduce the peak pressure from strong explosions below, very porous materials, which strongly reduce pressure but do not increase momentum, are preferred to non-porous materials, which amplify momentum but do not decrease pressure. These predictions are in qualitative accord with the results of experiments at Los Alamos in which projectiles from high velocity, large caliber cannons were stopped by one to two sandbags. The studies were performed primarily to determine the effectiveness of sand in stopping fragments of various sizes, but could be extended to study sand's effectiveness in attenuating blast pressure. It would also be useful to test the above predictions on the effectiveness of media with higher porosity. Water barriers have been discussed but not deployed in previous retrofit survivability studies for overseas embassies. They would detect the flash from the mine detonation below, trigger a thin layer of explosive above a layer of water, and drive water droplets into the approaching blast wave. The blast loses energy in evaporating the droplets and loses momentum in slowing them. Under favorable conditions that could attenuate the pressure in the blast enough to prevent the penetration or disruption of the vehicle. However, such barriers would depend on prompt and reliable detonation detection and water droplet dispersal, which have not been tested. There is a large literature on the theoretical effec

Gas-engine chiller cools co-op apartment building  

Science Conference Proceedings (OSTI)

In the fall of 1993, the Bronxville Knolls Tower Co-op Board was faced with a now prevalent problem. Its 12-story, 63-unit cooperative in Bronxville, NY, which encompasses approximately 125,000 sq ft, including the parking garage, was being air conditioned by an aging 200-ton centrifugal chiller using CFC-11 refrigerant. As of January 1, 1996, CFCs are no longer manufactured in the US. The board wanted to determine whether the existing chiller could economically be retained or if it should be replaced with new equipment using a non-CFC refrigerant. From energy study to completion, steps taken in this chiller retrofit project are discussed in this article.

Lighting retrofit monitoring for the Federal sector-strategies and results at the DOE Forrestal Building  

SciTech Connect

Pacific Northwest Laboratory (PNL), the US Department of Energy (DOE) Federal Energy Management Program (FEMP), and Potomac Electric Power Company (PEPCO) have been conducting short-term monitoring studies at the Forrestal Building, headquarters of the DOE, since 1990. These studies were an integral part of the Shared Energy Savings (SES) lighting retrofit project completed in 1993. The overall goal of the project was to reduce electricity consumption at the Forrestal Building. One objective of the project was to use the building as a model for other federal SES lighting retrofit efforts. A complete short-term monitoring strategy in support of the SES project was developed. The strategy included baseline measurements of electrical consumption, performance measurements of proposed retrofits, and post-retrofit measurements of electricity consumption. Measurements included power consumption, power harmonics, and lighting levels. The results show a 56% reduction in electrical power consumed for lighting, as well as improved power quality and increased lighting levels.

The live test demonstration (LTD) of lighting retrofit technologies at the DOE Forrestal Building  

SciTech Connect

DOE`s Forrestal Building in Washington, DC, has successfully awarded a performance-based shared energy savings contract for retrofit of office and hallway lighting systems. The winning contractor estimates that the retrofit (and associated occupancy sensors) will lead to savings of up to 62% of the power currently used for lighting, with an estimated annual cost savings of $340,000. The retrofit will also increase lighting levels to required levels, while reducing total harmonic distortion on the lighting circuits. The performance-based shared energy savings approach to lighting retrofits will result in a guaranteed contract to maintain lighting levels and savings for the next seven years. Over the life of the contract, the shared energy savings approach will provide $1 million each for DOE and the contractor.

SciTech Connect

This report describes results of a technical, financial and environmental assessment study for a project, which would have included a new TCS micronized coal-fired heating plant for the Produkcja I Hodowla Roslin Ogrodniczych (PHRO) Greenhouse Complex; Krzeszowice, Poland. Project site is about 20 miles west of Krakow, Poland. During the project study period, PHRO utilized 14 heavy oil-fired boilers to produce heat for its greenhouse facilities and also home heating to several adjacent apartment housing complexes. The boilers burn a high-sulfur content heavy crude oil, called mazute, The project study was conducted during a period extended from March 1996 through February 1997. For size orientation, the PHRO Greenhouse complex grows a variety of vegetables and flowers for the Southern Poland marketplace. The greenhouse area under glass is very large and equivalent to approximately 50 football fields, The new micronized coal fired boiler would have: (1) provided a significant portion of the heat for PHRO and a portion of the adjacent apartment housing complexes, (2) dramatically reduced sulfur dioxide air pollution emissions, while satisfying new Polish air regulations, and (3) provided attractive savings to PHRO, based on the quantity of displaced oil.

The evaluation of retrofit measures in a tall residential building  

SciTech Connect

As part of a joint demonstration effort involving the US Department of Energy (DOE), the US Department of Housing and Urban Development (HUD), Boston Edison Company (BECo), and the Chelsea Housing Authority, Oak Ridge National Laboratory (ORNL) participated in the evaluation of energy and demand saving retrofits for a tall residential building located in Boston. The thirteen story all-electric building underwent window, lighting, and control renovations in December, 1992. annual energy consumption was reduced by 15% and peak demand fell by 17%. Hourly should building consumption data were available for the comparison of pre- and post- conditions and for calibration of a DOE-2.1D simulation model. The analysis found the window retrofit accounted for 90% of total energy savings and 95% of average demand savings, due to reductions in both conduction and infiltration. Benefits from lighting retrofits were low in cooling months and negligible in winter months due to the increase in the demand for electric resistance heating which was proportional to the reduction in lighting capacity. Finally, the simulation model verified that heating system controls had not been used as intended, and that the utility rate structure would not allow cost savings from the original control strategy. These results and other interesting lessons learned are presented.

Manufactured Home Energy Audit user`s manual  

SciTech Connect

The Manufactured Home Energy Audit (MHEA) is a software tool that predicts manufactured home energy consumption and recommends weatherization retrofit measures. It was developed to assist local weatherization agencies working with the US Department of Energy (DOE) Weatherization Assistance Program. Whether new or experienced, employed within or outside the Weatherization Assistance Program, all users can benefit from incorporating MHEA into their manufactured home weatherization programs. DOE anticipates that the state weatherization assistance programs that incorporate MHEA into their programs will find significant growth in the energy and cost savings achieved from manufactured home weatherization. The easy-to-use MHEA displays a colorful, graphical interface for entering simple inputs and provides understandable, usable results. The user enters information about the manufactured home construction, heating equipment, cooling equipment, and weather site. MHEA then calculates annual energy consumption using a simplified building energy analysis technique. MHEA stands apart from other building energy analysis tools in many ways. Calculations incorporated into the computer code specifically address manufactured home heating and cooling load trends. The retrofit measures evaluated by MHEA are all applicable to manufactured homes. Help messages describe common manufactured home weatherization practices as well as provide hints on how to install retrofit measures. These and other features help make MHEA easy to use when evaluating energy consumption and the effects of weatherization retrofit measures for manufactured homes.

An Experimental and Analytical Evaluation of Wall And Window Retrofit Configurations: Supporting the Residential Retrofit Best Practices Guide  

SciTech Connect

A Retrofit Best Practices Guide was developed to encourage homeowners to consider energy conservation issues whenever they modify their siding or windows. In support of this guide, an experimental program was implemented to measure the performance of a number of possible wall siding and window retrofit configurations. Both thermal and air-leakage measurements were made for a 2.4 x 2.4 m (8 x 8 ft) wall section with and without a 0.9 x 1.2 m (3 x 4 ft) window. The windows tested were previously well-characterized at a dedicated window test facility. A computer model was also used to provide information for the Best Practices Guide. The experimental data for walls and windows were used in conjunction with this model to estimate the total annual energy savings for several typical houses in a number of different locations.

Evaluation of passive solar retrofit options  

DOE Green Energy (OSTI)

An evaluation framework has been developed which allows for the assessment of the role of passive solar retrofit in the nationwide reduction of conventional fuel use. Three types of analysis are proposed within this framework: the physical/technical capability of the present housing stock to incorporate passive solar retrofit; the economic feasibility of the application of retrofit designs; and the actual market potential or acceptance of these alternative retrofit options. Each type of analysis has specific data requirements and a series of evaluation procedures to help establish estimates of the potential for passive solar retrofit in the present housing stock. The data requirements with their respective sources and evaluation procedures for the first two types of analysis-physical/technical setting and economic feasibility, are examined. A distinction is drawn between community specific case studies and more generalized national assessments. Information derived from these three types of analysis, whether case specific or national in scope, can then be used in an evaluation of potential economic impacts. The establishment of regional economic benefits and costs werve as a measure of the merit or attractiveness of the implementation of a passive solar retrofit program.

Selecting effective fluorescent lamp and ballast for retrofit in the continental United States. Final report  

SciTech Connect

Electrical lighting is a major contributor to daytime peak energy demand, accounting for about 30 percent of total electricity consumption in most Army facilities. Some of this energy may be wasted because many existing lighting systems at Army Installations use outmoded technologies. While recent technology has improved the energy efficiency of all lighting systems, fluorescent lighting-the most widely used interior building lighting-has shown the greatest efficiency gains. Retrofits using high-efficiency fluorescent lamps and ballasts can yield significant operating cost savings. High-efficiency fluorescent lighting systems are widely available, but current information on their performance characteristics is highly technical and not easily accessible to Army facility managers considering retrofit options. This report provides a single, accessible source that summarizes fluorescent lamp and ballast performance characteristics and outlines selection procedures.

Monitoring of the performance of a solar-heated-and-cooled apartment building. Final report  

DOE Green Energy (OSTI)

A 12-unit student apartment building was retrofitted for solar heating and cooling and hot water. The retrofit of the all-electric building resulted in a system consisting of an array of 1280 square feet of concentrating tracking collectors, a 5000-gallon hot water storage vessel, a 500-gallon chilled water storage vesel, a 25-ton absorption chiller, and a two-pipe hydronic air conditioning system. The solar air conditioning equipment is installed in parallel with the existing conventional electric heating and cooling system, and the solar domestic water heating serves as preheat to the existing electric water heaters. The system was fully instrumented for temperature, flow rate, electrical power, and meteorological measurements. The data indicate that 11.2% of the cooling load was met by solar and 8.2% of the total load (cooling plus hot water) was met by solar. The performance of the collector array was determined to be approximately 60% of that suggested by the manufacturer. Steady-state chiller operation exhibited a C.O.P. very close to the manufacturer's specified performance values, but the time-averaged chiller C.O.P. is degraded due to cycling. The composite solar fraction (8.2%) is less than solar cooling only (11.2%) because there was no solar domestic hot water delivery during this monitoring period. The evaluation of system performance for the cooling season indicates a lower performance than expected. However, system performance in the cooling mode can be improved by better adjustment of the thermostats and controls. Continued data collection and analysis should be performed, to improve system operations, assess performance limits, and compare results with design projections.

Analysis of institutional mechanisms affecting residential and commercial buildings retrofit  

SciTech Connect

Barriers to energy conservation in the residential and commercial sectors influence (1) the willingness of building occupants to modify their energy usage habits, and (2) the willingness of building owners/occupants to upgrade the thermal characteristics of the structures within which they live or work and the appliances which they use. The barriers that influence the willingness of building owners/occupants to modify the thermal efficiency characteristics of building structures and heating/cooling systems are discussed. This focus is further narrowed to include only those barriers that impede modifications to existing buildings, i.e., energy conservation retrofit activity. Eight barriers selected for their suitability for Federal action in the residential and commercial sectors and examined are: fuel pricing policies that in the short term do not provide enough incentive to invest in energy conservation; high finance cost; inability to evaluate contractor performance; inability to evaluate retrofit products; lack of well-integrated or one-stop marketing systems (referred to as lack of delivery systems); lack of precise or customized information; lack of sociological/psychological incentives; and use of the first-cost decision criterion (expanded to include short-term payback criterion for the commercial sector). The impacts of these barriers on energy conservation are separately assessed for the residential and commercial sectors.

Leakage of US Homes: Regression Analysis and Improvements from Retrofit Leakage of US Homes: Regression Analysis and Improvements from Retrofit Title Air Leakage of US Homes: Regression Analysis and Improvements from Retrofit Publication Type Report LBNL Report Number LBNL-5966E Year of Publication 2012 Authors Chan, Wanyu R., Jeffrey Joh, and Max H. Sherman Date Published 08/2012 Keywords air infiltration, blower door, fan pressurization measurements, retrofit, weatherization Abstract LBNL Residential Diagnostics Database (ResDB) contains blower door measurements and other diagnostic test results of homes in United States. Of these, approximately 134,000 single-family detached homes have sufficient information for the analysis of air leakage in relation to a number of housing characteristics. We performed regression analysis to consider the correlation between normalized leakage and a number of explanatory variables: IECC climate zone, floor area, height, year built, foundation type, duct location, and other characteristics. The regression model explains 68% of the observed variability in normalized leakage. ResDB also contains the before and after retrofit air leakage measurements of approximately 23,000 homes that participated in weatherization assistant programs (WAPs) or residential energy efficiency programs. The two types of programs achieve rather similar reductions in normalized leakage: 30% for WAPs and 20% for other energy programs.

The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: Final Report  

SciTech Connect

This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

Technique for tracking the effect of weatherization retrofits on low-income housing  

SciTech Connect

This report presents a technique for analyzing the effect of energy saving retrofits installed in low-income housing under a nationwide weatherization demonstration program. A tracking technique, based on the calculated balance-point temperature of each home prior to the weatherization, was developed to estimate the would-be fuel consumption over a period of time if the house had not been weatherized. The savings in fuel consumption for a home can be determined from the difference between the actual usage after retrofit and the calculated usage if it were not retrofitted. Besides the overall reduction, the saving in energy usage during different time periods while the house is being weatherized can be visualized from the graphical representation of the tracking technique.

Image Recognition System for Automated Lighting Retrofit Assessment  

E-Print Network (OSTI)

Buildings are responsible for approximately 40% of all US energy use and carbon emissions. Lighting technologies continue to evolve, leading to potential energy savings through retrofits of lighting systems. Building lighting systems is typically the first item evaluated by commercial and industrial energy auditors. This paper presents the first phase of a project to develop unmanned aerial and ground vehicles capable of conducting autonomous energy audits of commercial buildings. The paper presents a prototype system that can enumerate and classify the lighting in a building using an optical camera, accelerometer, spectrometer, and distance sensor. As the aerial vehicle navigates throughout a room, the prototype system captures images and collects frequency data of lighting. The system employs image recognition techniques to quantify lighting in each room. Using the unique frequency spectrum of each lighting type, the prototype system classifies the different types of lighting with the spectrometer. An accompanying software program then analyzes the quantity and type of lighting to recommend economical alternatives, or lighting retrofits.

Heating Facilities, Virginia Lake Townhouses and Apartments, Reno, Nevada.  

DOE Green Energy (OSTI)

The Virginia Lake Townhouses and Apartments are located in a 12 acre parcel in the geographic center of Reno, Nevada. There are 148 apartments, consisting of 70 single story garden apartments in 10 buildings, 40 two story townhouses in six buildings, and 38 two story apartments in five buildings. All apartments are presently heated with individual natural gas fired forced air furnaces. Hot water is provided by gas fired water heaters, except for the 40 older townhouses which are using water directly from a geothermal source. This water has now been found to be unsuitable for potable use. Located on the property are two geothermal wells, complete with pumps. The larger well can deliver 500 gallons per min., and the smaller well 65 gallons per min., of the 135/sup 0/F geothermal water. The Geo-Heat Utilization Center has been asked to determine a scheme for using the geothermal water from these wells to provide the needed space and hot water heating for the 148 apartments. An outdoor swimming pool also requires heating. Space heating in all three types of apartments will be accomplished through the installation of finned water coils in existing ductwork or furnaces. Geothermal water will be pumped from Well No. 2 through a main distribution system and used directly in the coils. Piping system specifics are available in the Appendix.

Analysis of Energy Efficiency Measures in Rehabilitation of Multifamily Housing Units  

E-Print Network (OSTI)

An apartment building in Austin, Texas, and one in Boston, Massachusetts, were analyzed to determine the cost-effectiveness of energy efficiency measures. To determine expected energy and cost savings resulting from a set of proposed retrofit measures, hour-by-hour simulations were conducted using the DOE-2.1C building energy analysis computer program. Based on detailed audit data, supplemented by field-measurements in the case of the Austin apartment building, the simulations were run for base case (preretrofit) conditions for each building. Metered electricity and gas consumption was used to calibrate the input data. A series of proposed retrofit measures was run for each building using the calibrated preretrofit model as the reference. Annual energy and cost savings were calculated separately for each measure and for the combined set of measures. For the Austin building the combined set of 11 measures yielded expected savings of $3,710/year, a 42% savings in site energy. The combination of the 7 measures considered for the Boston building yielded expected savings of $1.292/year, and annual energy savings of nearly 75%. Measured in situ air conditioner performance for two of the Austin apartments showed EERs of 5.70 and 5.55, indicating an efficiency degradation of 22% and 24%, respectively, after 16 years of operation.

Diesel plant retrofitting options to enhance decentralized electricity supply in Indonesia  

Science Conference Proceedings (OSTI)

Over the last 20 years, the government of Indonesia has undertaken an extensive program to provide electricity to the population of that country. The electrification of rural areas has been partially achieved through the use of isolated diesel systems, which account for about 20% of the country`s generated electricity. Due to many factors related to inefficient power production with diesels, the National Renewable Energy Laboratory, in conjunction with PLN, the Indonesian national utility, Community Power Corporation, and Idaho Power Company, analyzed options for retrofitting existing diesel power systems. This study considered the use of different combinations of advanced diesel control, the addition of wind generators, photovoltaics and batteries to reduce the systems of overall cost and fuel consumption. This analysis resulted in a general methodology for retrofitting diesel power systems. This paper discusses five different retrofitting options to improve the performance of diesel power systems. The systems considered in the Indonesian analysis are cited as examples for the options discussed.

Advanced Rooftop Control (ARC) Retrofit: Field-Test Results  

Science Conference Proceedings (OSTI)

The multi-year research study was initiated to find solutions to improve packaged equipment operating efficiency in the field. Pacific Northwest National Laboratory (PNNL), with funding from the U.S. Department of Energys (DOEs) Building Technologies Office (BTO) and Bonneville Power Administration (BPA) conducted this research, development and demonstration (RD&D) study. Packaged equipment with constant speed supply fans is designed to provide ventilation at the design rate at all times when the fan is operating as required by building code. Although there are a number of hours during the day when a building may not be fully occupied or the need for ventilation is lower than designed, the ventilation rate cannot be adjusted easily with a constant speed fan. Therefore, modulating the supply fan in conjunction with demand controlled ventilation (DCV) will not only reduce the coil energy but also reduce the fan energy. The objective of this multi-year research, development and demonstration project was to determine the magnitude of energy savings achievable by retrofitting existing packaged rooftop air conditioners with advanced control strategies not ordinarily used for packaged units. First, through detailed simulation analysis, it was shown that significant energy (between 24% and 35%) and cost savings (38%) from fan, cooling and heating energy consumption could be realized when packaged air conditioning units with gas furnaces are retrofitted with advanced control packages (combining multi-speed fan control, integrated economizer controls and DCV). The simulation analysis also showed significant savings for heat pumps (between 20% and 60%). The simulation analysis was followed by an extensive field test of a retrofittable advanced rooftop unit (RTU) controller.

Evaluation of DOE's Partnership in Low-Income Residential Retrofit (PILIRR) Program  

Science Conference Proceedings (OSTI)

In July 1986, the US Department of Energy (DOE) awarded competitive grants to five states to conduct pilot projects to establish partnerships and use resource leveraging to stimulate support for low-income residential energy retrofits. The projects were conducted under DOE's Partnerships in Low-Income Residential Retrofit (PILIRR) Program. These projects have been monitored and analyzed through a concurrent process evaluation conducted by the Pacific Northwest Laboratory (PNL). This study reports the findings of that evaluation. The overriding goal of the PILIRR Program was to determine whether the states could stimulate support for low-income residential energy improvements from non-federal sources. The goal for the process evaluation was to conduct an assessment of the processes used by the states and the extent to which they successfully established partnerships and leveraged resources. Five states were selected to participate in the program: Florida, Iowa, Kentucky, Oklahoma and Washington. Each state proposed a different approach to promote non-federal support for low-income residential weatherization. Three of the five states--Florida, Iowa, and Washington--established partnerships that led to retrofits during the monitoring period (October 1986--October 1988). Kentucky established its partnership during the monitoring period, but did not accomplish its retrofits until after monitoring was complete. Oklahoma completed development of its marketing program and had begun marketing efforts by the end of the monitoring period. 16 refs., 7 figs., 1 tab.

NLE Websites -- All DOE Office Websites (Extended Search)

Indoor-outdoor air leakage of apartments and commercial buildings. Indoor-outdoor air leakage of apartments and commercial buildings. Title Indoor-outdoor air leakage of apartments and commercial buildings. Publication Type Report Year of Publication 2006 Authors Price, Phillip N., Arman Shehabi, Wanyu R. Chan, and Ashok J. Gadgil Publisher Lawrence Berkeley National Laboratory Abstract We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

Experience with 113 Retrofit Insulation Surveys  

E-Print Network (OSTI)

We have surveyed 113 plants for thirteen clients. The results of 21 recent surveys at today's average fuel price, show an average project scope generation of $151,000 while saving about 5MMBTU/hour with a 72% DCF rate of return. The size of the retrofit project generated, or scope, is of course sensitive to the fuel price. This is an important consideration because of the variability of fuel price. A study of the effect of fuel price on project scope generation and on return has been made using sophisticated computer programs designed for this purpose. These results indicate that scope generation may vary from $50,000 for $3.00 fuel up to $80,000 for $6.00 fuel. When this happens, the project return will increase from 100% up to 165% per year. The main problem that we have found with retrofit insulation surveys is the processing of detail in existing plants. The solution is the preparation or selection of the right system for approaching the problem utilizing computer programs. The time required to generate systematic approaches to insulation surveys and the generation of retrofit projects are sizable. The continued heat losses while studying the project are also significant. Thus, the heat losses suffered while deciding how to insulate can be sufficient to pay for an insulation survey.

Retrofitted feedwater heat storage for steam electric power stations peaking power engineering study. Final report  

DOE Green Energy (OSTI)

The technical and economic feasibility of retrofitting existing nuclear or fossil-fueled steam power plants with feedwater thermal energy storage (TES) systems for peaking power applications was investigated. A major objective of the study was to determine if retrofitted thermal energy storage (RTES) systems could result in significant fuel savings in oil- and gas-fired peaking plants. From this study it was concluded that RTES require high capital expenditure, excessive plant downtime for installation (16 mo for fossil-fuel; 24 mo for nuclear), that retrofitting 17,000 MWe of coal and nuclear plants would result in only about 2 percent annual savings in oil consumed by the U.S. utility industry in 1974, and that the technical questions which remain could best be answered by retrofitting a relatively new reliable plant as a test facility. The utility industry is receptive to the TES concept but not to the RTES concept. It is recommended that no further effort be expended on RTES, that TES studies should concentrate on coal and nuclear plants, and that a TES Proof-of-Concept Facility should be designed and constructed.

Effective method for MHD retrofit of power plants  

DOE Green Energy (OSTI)

Retrofitting existing power plants with an open-cycle MHD system has been re-examined in light of recent developments in the heat and seed recovery technology area. A new retrofit cycle configuration has been developed which provides for a direct gas-gas coupling; also, the MHD topping cycle can be decoupled from the existing plant for either separate or joint operation. As an example, the MHD retrofit concept has been applied to Illinois Power Company's Vermilion Station No. 1, a coal-fired power plant presently in operation. Substantial increases in efficiency have been demonstrated and the economic validity of the MHD retrofit approach has been established.

Considering lighting system performance and HVAC interactions in lighting retrofit analyses  

SciTech Connect

The performance of several typical fluorescent lighting retrofits are examined using analysis methods of varying sophistication. Estimates of energy and lighting performance based on the simple non-application specific data generally available tend to overestimate the energy savings obtained with the various retrofits by 10-30%. Adding a simple correction to account for cooling benefits exacerbates the error unless heating penalties are also considered. An analysis method that takes into account the thermal application factor of the lighting system shows that the error is typically due to systematically overestimating the energy usage of the original lighting system. If thermal application factor is considered, then detailed HVAC calculations do not significantly improve the energy-savings estimate.

Retrofits for Improved Heat Rate and Availability: Circulating Water Heat Recovery Retrofits  

Science Conference Proceedings (OSTI)

Circulating water heat recovery is a means of directly increasing the thermal efficiency of a power plant. If only fuel savings are considered, the economic benefit is often only marginal. However, when increased megawatt output and heat-rate improvements are included in the economic analysis, such retrofits can be attractive, with break-even fuel costs sometimes approaching $1/million Btu.

Byggmeister Test Home: Analysis and Initial Results of Cold Climate Wood-Framed Home Retrofit  

SciTech Connect

BSC seeks to further the energy efficiency market for New England area retrofit projects by supporting projects that are based on solid building science fundamentals and verified implementation. With the high exposure of energy efficiency and retrofit terminology being used in the general media at this time, it is important to have evidence that measures being proposed will in fact benefit the homeowner through a combination of energy savings, improved durability, and occupant comfort. There are several basic areas of research to which the technical report for these test homes can be expected to contribute. These include the combination of measures that is feasible, affordable and acceptable to homeowners as well as expectations versus results. Two Byggmeister multi-family test homes in Massachusetts are examined with the goal of providing case studies that could be applied to other similar New England homes.

Indoor-Outdoor Air Leakage of Apartments and Commercial Buildings  

SciTech Connect

We compiled and analyzed available data concerning indoor-outdoor air leakage rates and building leakiness parameters for commercial buildings and apartments. We analyzed the data, and reviewed the related literature, to determine the current state of knowledge of the statistical distribution of air exchange rates and related parameters for California buildings, and to identify significant gaps in the current knowledge and data. Very few data were found from California buildings, so we compiled data from other states and some other countries. Even when data from other developed countries were included, data were sparse and few conclusive statements were possible. Little systematic variation in building leakage with construction type, building activity type, height, size, or location within the u.s. was observed. Commercial buildings and apartments seem to be about twice as leaky as single-family houses, per unit of building envelope area. Although further work collecting and analyzing leakage data might be useful, we suggest that a more important issue may be the transport of pollutants between units in apartments and mixed-use buildings, an under-studied phenomenon that may expose occupants to high levels of pollutants such as tobacco smoke or dry cleaning fumes.

DEEP RESIDENTIAL RETROFITS - USING LESS AND LIVING BETTER DEEP RESIDENTIAL RETROFITS - USING LESS AND LIVING BETTER Speaker(s): Iain Walker Date: December 11, 2009 - 12:00pm Location: 90-3122 (This is a repeat of the Nov. 18 ME EET Seminar on campus) There are currently thousands of federal, state and utility programs starting up throughout he nation to retrofit existing homes. Most of these programs have moderate savings goals on the order of 20%, but to really make an impact and make the nations housing stock sustainable we need savings of 70% or more. This requires fundamental changes in the way we think about retrofits. We need better diagnostics to determine how houses perform - both before and after retrofitting, we need better ways of simulating home performance so we can make better decisions about what to do to a home to

CASE STUDY OF DUCT RETROFIT OF A 1985 HOME AND GUIDELINES FOR ATTIC AND CRAWL SPACE DUCT SEALING  

SciTech Connect

The U.S. Department of Energy (DOE) is fully committed to research for developing the information and capabilities necessary to provide cost-effective residential retrofits yielding 50% energy savings within the next several years. Heating, ventilation, and air conditioning (HVAC) is the biggest energy end use in the residential sector, and a significant amount of energy can be wasted through leaky ductwork in unconditioned spaces such as attics and crawl spaces. A detailed duct sealing case study is presented for one house along with nine brief descriptions of other duct retrofits completed in the mixed-humid climate. Costs and estimated energy savings are reported for most of the ten houses. Costs for the retrofits ranged from $0.92/ft2 to $1.80/ft2 of living space and estimated yearly energy cost savings due to the duct retrofits range from 1.8% to 18.5%. Lessons learned and duct sealing guidelines based on these ten houses, as well as close work with the HVAC industry in the mixed-humid climate of East Tennessee, northern Georgia, and south-central Kentucky are presented. It is hoped that the lessons learned and guidelines will influence local HVAC contractors, energy auditors, and homeowners when diagnosing or repairing HVAC duct leakage and will be useful for steering DOE s future research in this area.

Manufactured Home Energy Audit (MHEA)Users Manual (Version 7)  

Science Conference Proceedings (OSTI)

The Manufactured Home Energy Audit (MHEA) is a software tool that predicts manufactured home energy consumption and recommends weatherization retrofit measures. It was developed to assist local weatherization agencies working with the U.S. Department of Energy (DOE) Weatherization Assistance Program. Whether new or experienced, employed within or outside the Weatherization Assistance Program, all users can benefit from incorporating MHEA into their manufactured home weatherization programs. DOE anticipates that the state weatherization assistance programs that incorporate MHEA into their programs will find significant growth in the energy and cost savings achieved from manufactured home weatherization. The easy-to-use MHEA uses a relatively standard Windows graphical interface for entering simple inputs and provides understandable, usable results. The user enters information about the manufactured home construction, heating equipment, cooling equipment appliances, and weather site. MHEA then calculates annual energy consumption using a simplified building energy analysis technique. Weatherization retrofit measures are evaluated based on the predicted energy savings after installation of the measure, the measure cost, and the measure life. Finally, MHEA recommends retrofit measures that are energy and cost effective for the particular home being evaluated. MHEA evaluates each manufactured home individually and takes into account local weather conditions, retrofit measure costs, and fuel costs. The recommended package of weatherization retrofit measures is tailored to the home being evaluated. More traditional techniques apply the same package of retrofit measures to all manufactured homes, often the same set of measures that are installed into site-built homes. Effective manufactured home weatherization can be achieved only by installing measures developed specifically for manufactured homes. The unique manufactured home construction characteristics require that each of these measures is evaluated separately in order to devise a package of measures that will result in high energy and dollar savings. MHEA stands apart from other building energy analysis tools in many ways. Calculations incorporated into the computer code specifically address manufactured home heating and cooling load trends. The retrofit measures evaluated by MHEA are all applicable to manufactured homes. Help messages describe common manufactured home weatherization practices as well as provide hints on how to install retrofit measures. These and other features help make MHEA easy to use when evaluating energy consumption and the effects of weatherization retrofit measures for manufactured homes. The National Renewable Energy Laboratory originally developed MHEA for the U.S. Department of Energy Weatherization Assistance Program. Conversion to a Windows-based program with additional modifications has been performed by the Oak Ridge National Laboratory. Many energy consumption and economic calculations resemble those found in the Computerized Instrumented Residential Audit written by Lawrence Berkeley National Laboratory and the National Energy Audit written by Oak Ridge National Laboratory. The calculations are similar in structure but have been altered to more accurately represent a manufactured home's unique energy use characteristics. Most importantly, MHEA helps meet the DOE Weatherization Assistance Program goals to increase client comfort and use federal dollars wisely.

Field Test Evaluation of Conservation Retrofits of Low-Income, Single-Family Buildings in Wisconsin: Audit Field Test Implementation and Results  

SciTech Connect

This report describes the field test of a retrofit audit. The field test was performed during the winter of 1985-86 in four South Central Wisconsin counties. The purpose of the field test was to measure the energy savings and cost effectiveness of the audit-directed retrofit program for optimizing the programs benefit-to-cost ratio. The audit-directed retrofit program is described briefly in this report and in more detail by another report in this series (ORNL/CON-228/P3). The purpose of this report is to describe the methods and results of the field test. Average energy savings of the 20 retrofitted houses are likely (0.90 probability) to lie between 152 and 262 therms/year/house. The most likely value of the average savings is 207 therms/year/house. These savings are significantly (p < .05) smaller than the audit-predicted savings (286 therms/year/house). Measured savings of individual houses were significantly different than predicted savings for half of the houses. Each house received at least one retrofit. Thirteen of the 20 retrofitted houses received a new condensing furnace or blown-in wall insulation; all but two of the houses received one or more minor retrofits. The seven houses which received condensing furnaces saved, on average, about as much as predicted, but three of the seven houses had significantly more or less savings than predicted. The six houses which received wall insulation saved, on average, about half as much as predicted. The remaining houses which received only minor retrofits saved, on average, less than predicted, but the difference was not significant. Actual retrofit costs were close to expected costs. Overall measured energy savings averaged 15 therms/year per hundred retrofit dollars invested. Houses which received wall insulation or a condensing furnace did slightly better, and the houses which received only minor retrofits did poorly. When estimated program costs were included, average savings dropped to about 13 therms/year/per hundred dollars. The uncertainty associated with the energy savings means that these comparisons of savings and costs also have large uncertainties.

MHD retrofit of steam power plants. Feasibility study. Summary and conclusions, Part I  

DOE Green Energy (OSTI)

The US Department of Energy Division of Magnetohydrodynamics (DOE/MHD) initiated this study to evaluate the feasibility of a retrofit option to reduce the time and cost of commercializing MHD. The MHD retrofit option will integrate a nominal 260 megawatt thermal (MWt) MHD topping cycle into an existing or scheduled private utility steam plant; this facility will test both the MHD system and the combined operation of the MHD/steam plant. The 260 MWt input level was determined to be the size which could most effectively demonstrate and verify the engineering design and operational characteristics of a coal-fired, open-cycle, MHD power plant. Details are presented. A goal of the MHD program is to have operational by the year 2003 a commercial size, fully integrated MHD plant. This would be accomplished by demonstrating commercial scale, baseload performance of a fully integrated, MHD/steam power plant. (WHK)

DEMONSTRATION OF A FULL-SCALE RETROFIT OF THE ADVANCED HYBRID PARTICULATE COLLECTOR TECHNOLOGY  

Science Conference Proceedings (OSTI)

The Advanced Hybrid Particulate Collector (AHPC), developed in cooperation between W.L. Gore & Associates and the Energy & Environmental Research Center (EERC), is an innovative approach to removing particulates from power plant flue gas. The AHPC combines the elements of a traditional baghouse and electrostatic precipitator (ESP) into one device to achieve increased particulate collection efficiency. As part of the Power Plant Improvement Initiative (PPII), this project was demonstrated under joint sponsorship from the U.S. Department of Energy and Otter Tail Power Company. The EERC is the patent holder for the technology, and W.L. Gore & Associates was the exclusive licensee for this project. The project objective was to demonstrate the improved particulate collection efficiency obtained by a full-scale retrofit of the AHPC to an existing electrostatic precipitator. The full-scale retrofit was installed on an electric power plant burning Powder River Basin (PRB) coal, Otter Tail Power Company's Big Stone Plant, in Big Stone City, South Dakota. The $13.4 million project was installed in October 2002. Project related testing concluded in December 2005. The following Final Technical Report has been prepared for the project entitled ''Demonstration of a Full-Scale Retrofit of the Advanced Hybrid Particulate Collector Technology'' as described in DOE Award No. DE-FC26-02NT41420. The report presents the operation and performance results of the system.

New and retrofit solar hot water installations in Florida, January--June 1977  

SciTech Connect

The purpose of this project was to ascertain the number of solar hot water installations in new buildings versus the number retrofitted to existing buildings in Florida during the January to June period of 1977. The methodology was to survey all installations started, in progress, or completed during that period. A by-product of the survey is a comprehensive list of manufacturers and another of distributors and installers in Florida. The survey excludes space heating and cooling and pool heating applications. However, the latter is being considered for a separate survey. Installations included are in the single-family and multi-family residential, commercial, industrial and public sectors. In the single-family residential sector, care has been taken to determine a new or retrofit breakdown, average square footage of collector per installation, average cost per square foot of collector in Florida, and subsequently, using F-CHART and system sizing programs developed at the Center, the fraction of load supplied by solar and its equivalent barrels of oil saved per year.

Highly Efficient Small Form Factor LED Retrofit Lamp  

SciTech Connect

This report summarizes work to develop a high efficiency LED-based MR16 lamp downlight at OSRAM SYLVANIA under US Department of Energy contract DE-EE0000611. A new multichip LED package, electronic driver, and reflector optic were developed for these lamps. At steady-state, the lamp luminous flux was 409 lumens (lm), luminous efficacy of 87 lumens per watt (LPW), CRI (Ra) of 87, and R9 of 85 at a correlated color temperature (CCT) of 3285K. The LED alone achieved 120 lumens per watt efficacy and 600 lumen flux output at 25 C. The driver had 90% electrical conversion efficiency while maintaining excellent power quality with power factor >0.90 at a power of only 5 watts. Compared to similar existing MR16 lamps using LED sources, these lamps had much higher efficacy and color quality. The objective of this work was to demonstrate a LED-based MR16 retrofit lamp for replacement of 35W halogen MR16 lamps having (1) luminous flux of 500 lumens, (2) luminous efficacy of 100 lumens per watt, (3) beam angle less than 40{sup o} and center beam candlepower of at least 1000 candelas, and (4) excellent color quality.
