REVIEW REPORT: BUILDING C-400 THERMAL TREATMENT 90 PERCENT REMEDIAL DESIGN REPORT AND SITE INVESTIGATION, PGDP, PADUCAH, KENTUCKY  

Science Conference Proceedings (OSTI)

On 9 April 2007, the U.S. Department of Energy (DOE) Headquarters, Office of Soil and Groundwater Remediation (EM-22) initiated an Independent Technical Review (ITR) of the 90% Remedial Design Report (RDR) and Site Investigation (RDSI) for thermal treatment of trichloroethylene (TCE) in the soil and groundwater in the vicinity of Building C-400 at the Paducah Gaseous Diffusion Plant (PGDP). The general ITR goals were to assess the technical adequacy of the 90% RDSI and provide recommendations sufficient for DOE to determine if modifications are warranted pertaining to the design, schedule, or cost of implementing the proposed design. The ultimate goal of the effort was to assist the DOE Paducah/Portsmouth Project Office (PPPO) and their contractor team in ''removing'' the TCE source zone located near the C-400 Building. This report provides the ITR findings and recommendations and supporting evaluations as needed to facilitate use of the recommendations. The ITR team supports the remedial action objective (RAO) at C-400 to reduce the TCE source area via subsurface Electrical Resistance Heating (ERH). Further, the ITR team commends PPPO, their contractor team, regulators, and stakeholders for the significant efforts taken in preparing the 90% RDR. To maximize TCE removal at the target source area, several themes emerge from the review which the ITR team believes should be considered and addressed before implementing the thermal treatment. These themes include the need for: (1) Accurate and site-specific models as the basis to verify the ERH design for full-scale implementation for this challenging hydrogeologic setting; (2) Flexible project implementation and operation to allow the project team to respond to observations and data collected during construction and operation; (3) Defensible performance metrics and monitoring, appropriate for ERH, to ensure sufficient and efficient clean-up; and (4) Comprehensive (creative and diverse) contingencies to address the potential for system underperformance, and other unforeseen conditions These themes weave through the ITR report and the various analyses and recommendations. The ITR team recognizes that a number of technologies are available for treatment of TCE sources. Further, the team supports the regulatory process through which the selected remedy is being implemented, and concurs that ERH is a potentially viable remedial technology to meet the RAOs adjacent to C-400. Nonetheless, the ITR team concluded that additional efforts are needed to provide an adequate basis for the planned ERH design, particularly in the highly permeable Regional Gravel Aquifer (RGA), where sustaining target temperatures present a challenge. The ERH design modeling in the 90% RDR does not fully substantiate that heating in the deep RGA, at the interface with the McNairy formation, will meet the design goals; specifically the target temperatures. Full-scale implementation of ERH to meet the RAOs is a challenge in the complex hydrogeologic setting at PGDP. Where possible, risks to the project identified in this ITR report as ''issues'' and ''recommendations'' should be mitigated as part of the final design process to increase the likelihood of remedial success. The ITR efforts were organized into five lines of inquiry (LOIs): (1) Site investigation and target zone delineation; (2) Performance objectives; (3) Project and design topics; (4) Health and safety; and (5) Cross cutting and independent cost evaluation. Within each of these LOIs, the ITR team identified a series of unresolved issues--topics that have remaining uncertainties or potential project risks. These issues were analyzed and one or more recommendations were developed for each. In the end, the ITR team identified 27 issues and provided 50 recommendations. The issues and recommendations are briefly summarized below, developed in Section 5, and consolidated into a single list in Section 6. The ITR team concluded that there are substantive unresolved issues and system design uncertainties, resulting in technical and financial risks to DOE.

INDEPENDENT TECHNICAL REVIEW OF THE C-400 INTERIM REMEDIAL PROJECT PHASE I RESULTS, PADUCAH, KENTUCKY  

Science Conference Proceedings (OSTI)

The groundwater and soil in the vicinity of the C-400 Building at the Paducah Gaseous Diffusion Plant (PGDP), is contaminated with substantial quantities of industrial solvents, primarily trichoroethene (TCE). This solvent 'source' is recognized as a significant challenge and an important remediation target in the overall environmental cleanup strategy for PGDP. Thus, the cleanup of the C-400 TCE Source is a principal focus for the Department of Energy (DOE) and its contractors, and for PGDP regulators and stakeholders. Using a formal investigation, feasibility study and decision process, Electrical Resistance Heating (ERH) was selected for the treatment of the soil and groundwater in the vicinity of C-400. ERH was selected as an interim action to remove 'a significant portion of the contaminant mass of TCE at the C-400 Cleaning Building area through treatment' with the longer term goal of reducing 'the period the TCE concentration in groundwater remains above its Maximum Contaminant Level (MCL).' ERH is a thermal treatment that enhances the removal of TCE and related solvents from soil and groundwater. The heterogeneous conditions at PGDP, particularly the high permeability regional gravel aquifer (RGA), are challenging to ERH. Thus, a phased approach is being followed to implement this relatively expensive and complex remediation technology. Conceptually, the phased approach encourages safety and efficiency by providing a 'lessons learned' process and allowing appropriate adjustments to be identified and implemented prior to follow-on phase(s) of treatment. More specifically, early deployment targeted portions of the challenging RGA treatment zone with relatively little contamination reducing the risk of adverse collateral impacts from underperformance in terms of heating and capture. Because of the importance and scope of the C-400 TCE source remediation activities, DOE chartered an Independent Technical Review (ITR) in 2007 to assess the C-400 ERH plans prior to deployment and a second ITR to evaluate Phase I performance in September 2010. In this report, these ITR efforts are referenced as the '2007 ITR' and the 'current ITR', respectively. The 2007 ITR document (Looney et al., 2007) provided a detailed technical evaluation that remains relevant and this report builds on that analysis. The primary objective of the current ITR is to provide an expedited assessment of the available Phase I data to assist the PGDP team as they develop the lessons learned from Phase I and prepare plans for Phase II.

Thermal distribution systems in commercial buildings Thermal distribution systems in commercial buildings Title Thermal distribution systems in commercial buildings Publication Type Journal Article LBNL Report Number LBNL-51860 Year of Publication 2003 Authors Diamond, Richard C., Craig P. Wray, Darryl J. Dickerhoff, Nance Matson, and Duo Wang Start Page Chapter Abstract Previous research suggests that HVAC thermal distribution systems in commercial buildings suffer from thermal losses, such as those caused by duct air leakage and poor duct location. Due to a lack of metrics and data showing the potentially large energy savings from reducing these losses, the California building industry has mostly overlooked energy efficiency improvements in this area. The purpose of this project is to obtain the technical knowledge needed to properly measure and understand the energy efficiency of these systems. This project has three specific objectives: to develop metrics and diagnostics for determining system efficiencies, to develop design and retrofit information that the building industry can use to improve these systems, and to determine the energy impacts associated with duct leakage airflows in an existing large commercial building. The primary outcome of this project is the confirmation that duct leakage airflows can significantly impact energy use in large commercial buildings: our measurements indicate that adding 15% duct leakage at operating conditions leads to an increase in fan power of about 25 to 35%. This finding is consistent with impacts of increased duct leakage airflows on fan power that have been predicted by previous simulations. Other project outcomes include the definition of a new metric for distribution system efficiency, the demonstration of a reliable test for determining duct leakage airflows, and the development of new techniques for duct sealing. We expect that the project outcomes will lead to new requirements for commercial thermal distribution system efficiency in future revisions of California's Title 24.

The thermal mass can be utilized also to control the thermal load by storing thermal energy before HVAC operation. There are two ways to store thermal energy. One is by operating the HVAC system and the other is by natural ventilation, mainly at night. The latter could be combined with daily HVAC operation as a hybrid ventilation. Thermal mass storage is useful to decrease the hourly peak load and the daily thermal load and can be used for both cooling and heating purpose.

Demand Shifting With Thermal Mass in Large Commercial Buildings: Case Demand Shifting With Thermal Mass in Large Commercial Buildings: Case Studies and Tools Speaker(s): Peng Xu Date: March 9, 2007 - 12:00pm Location: 90-3122 The idea of pre-cooling and demand limiting is to pre-cool buildings at night or in the morning during off-peak hours, storing cooling energy in the building thermal mass and thereby reducing cooling loads during the peak periods. Savings are achieved by reducing on-peak energy and demand charges. The potential for utilizing building thermal mass for load shifting and peak demand reduction has been demonstrated in a number of simulation, laboratory, and field studies. Case studies in a number of office buildings in California has found that a simple demand limiting strategy reduced the chiller power by 20-100% (0.5-2.3W/ft2) during six

Hybrid Model of Existing Buildings for Transient Thermal Performance Estimation  

E-Print Network (OSTI)

Building level energy models are important to provide accurate prediction of energy consumption for building performance diagnosis and energy efficiency assessment of retrofitting alternatives for building performance upgrading. Simplified but physically meaningful models for existing buildings are preferable for practical applications. In this study, a hybrid building model is developed to describe building system for thermal performance prediction at building level. The model includes two parts. One part is the detailed physical models, which are the CTF models of building envelopes based on the easily available coincident detailed physical properties. The other part is the simplified 2R2C model for building internal mass, whose parameters are estimated and optimized using short-term monitored operation data. A genetic algorithm estimator is developed to optimize these parameters. The parameter optimization of the simplified model and the hybrid building model are validated in a high-rise commercial office building under various weather conditions.

Duct thermal performance models for large commercial buildings  

SciTech Connect

Despite the potential for significant energy savings by reducing duct leakage or other thermal losses from duct systems in large commercial buildings, California Title 24 has no provisions to credit energy-efficient duct systems in these buildings. A substantial reason is the lack of readily available simulation tools to demonstrate the energy-saving benefits associated with efficient duct systems in large commercial buildings. The overall goal of the Efficient Distribution Systems (EDS) project within the PIER High Performance Commercial Building Systems Program is to bridge the gaps in current duct thermal performance modeling capabilities, and to expand our understanding of duct thermal performance in California large commercial buildings. As steps toward this goal, our strategy in the EDS project involves two parts: (1) developing a whole-building energy simulation approach for analyzing duct thermal performance in large commercial buildings, and (2) using the tool to identify the energy impacts of duct leakage in California large commercial buildings, in support of future recommendations to address duct performance in the Title 24 Energy Efficiency Standards for Nonresidential Buildings. The specific technical objectives for the EDS project were to: (1) Identify a near-term whole-building energy simulation approach that can be used in the impacts analysis task of this project (see Objective 3), with little or no modification. A secondary objective is to recommend how to proceed with long-term development of an improved compliance tool for Title 24 that addresses duct thermal performance. (2) Develop an Alternative Calculation Method (ACM) change proposal to include a new metric for thermal distribution system efficiency in the reporting requirements for the 2005 Title 24 Standards. The metric will facilitate future comparisons of different system types using a common ''yardstick''. (3) Using the selected near-term simulation approach, assess the impacts of duct system improvements in California large commercial buildings, over a range of building vintages and climates. This assessment will provide a solid foundation for future efforts that address the energy efficiency of large commercial duct systems in Title 24. This report describes our work to address Objective 1, which includes a review of past modeling efforts related to duct thermal performance, and recommends near- and long-term modeling approaches for analyzing duct thermal performance in large commercial buildings.

Improving Glass Walls Thermal Resistance In Air-Conditioned Buildings  

E-Print Network (OSTI)

The solar radiation through an air conditioned building depends on what is called the building envelope. Building envelope consists of the surfaces that separate the inside from the building outdoors. Area, direction, and specifications of glass walls; as one of envelope surfaces; has an important impact on solar radiation. Design and construction of glass walls have significant effects on building comfort and energy consumption. This paper describes methods of improving glass walls thermal resistance in air conditioned buildings. Effect of glass wall radiation temperature on the indoor temperature distribution of building rooms is also investigated. Heat gain through various types of glass is discussed. Optimization and testing of these types are carried out theoretically and experimentally as well. A series of experiments on different types of glass with special strips is performed.

Simplified analysis of building thermal storage effects  

Science Conference Proceedings (OSTI)

Whatever performance is offered by simulation software, simple performance characterization is very welcome at all stages of a building's life cycle. Building designers, contractors, and operators need such characterization in order to interpret and to judge simulation as well as measurement results. It is common knowledge that most of building perturbations are not sinusoidal and not even harmonic. But it is, nevertheless, very convenient to define each time function as the superposition of a time average and a (fictitious) oscillation around this average. This is the old fashion method of performing a manual calculation. The CIBSE admittance procedure was developed on such basis. This paper demonstrates how such very simplified analysis can help in detailed simulation. A practical example is presented, which deals with overheating risk calculation and fan coil sizing for an office building located in Brussels. Detailed simulation results are translated into two very synthetic building characteristics, which appear as very convenient references when having to compare different cooling strategies. Such analysis should also offer better possibilities of comparisons among problems encountered and among solutions selected in different projects.

Performance of thermal distribution systems in large commercial buildings Performance of thermal distribution systems in large commercial buildings Title Performance of thermal distribution systems in large commercial buildings Publication Type Journal Article LBNL Report Number LBNL-44331 Year of Publication 2002 Authors Xu, Tengfang T., François Rémi Carrié, Darryl J. Dickerhoff, William J. Fisk, Jennifer A. McWilliams, Duo Wang, and Mark P. Modera Journal Energy and Buildings Volume 34 Start Page Chapter Pagination 215-226 Abstract This paper presents major findings of a field study on the performance of five thermal distribution systems in four large commercial buildings. The five systems studied are typical single-duct or dual-duct constant air volume (CAV) systems and variable air volume (VAV) systems, each of which serves an office building or a retail building with floor area over 2,000 m2. The air leakage from ducts are reported in terms of effective leakage area (ELA) at 25 Pa reference pressure, the ASHRAE-defined duct leakage class, and air leakage ratios. The specific ELAs ranged from 0.7 to 12.9 cm2 per m2 of duct surface area, and from 0.1 to 7.7 cm2 per square meter of floor area served. The leakage classes ranged from 34 to 757 for the five systems and systems sections tested. The air leakage ratios are estimated to be up to one-third of the fan- supplied airflow in the constant-air-volume systems. The specific ELAs and leakage classes indicate that air leakage in large commercial duct systems varies significantly from system to system, and from system section to system section even within the same thermal distribution system. The duct systems measured are much leakier than the ductwork specified as "unsealed ducts" by ASHRAE. Energy losses from supply ducts by conduction (including convection and radiation) are found to be significant, on the scale similar to the losses induced by air leakage in the duct systems. The energy losses induced by leakage and conduction suggest that there are significant energy-savings potentials from duct-sealing and insulation practice in large commercial buildings

Thermal Performance Evaluation of Innovative Metal Building Roof Assemblies  

Science Conference Proceedings (OSTI)

In order to meet the coming energy codes, multiple layers of various insulation types will be required. The demand for greater efficiency has pushed insulation levels beyond the cavity depth. These experiments show the potential for improving metal building roof thermal performance. Additional work is currently being done by several stakeholders, so the data is expanding. These experiments are for research and development purposes, and may not be viable for immediate use.

Computational Study on Thermal Properties of HVAC System with Building Structure Thermal Storage  

E-Print Network (OSTI)

Building structure thermal storage (BSTS) HVAC systems can store heat during nighttime thermal storage operation (nighttime operation hours) by using off-peak electricity and release it in the daytime air-conditioning operation (daytime operation hours) by utilizing a large amount of the thermal capacity of building structures such as beams, columns and floors composed of concrete. These BSTS systems have recently been considered as one method for leveling hourly electricity demands for HVAC on a day-to-day basis. Through a simulation using a model developed with experimental data, this paper describes how various factors for the design and operation of a BSTS quantitatively affect the charge/discharge performances of a HVAC system. As a result, the following was revealed: the thermal performance of the system is strongly influenced by the daily heat storage operation hours, supply air volume and supply air temperature during the nighttime operation hours, stored heat caused the total daytime cooling extraction to decrease by 11% to 58% and the daily total cooling extraction through nighttime to daytime to increase by 4% to 17% compared with the values of non- thermal storage HVAC system.

Thermal Solar Energy Systems for Space Heating of Buildings  

E-Print Network (OSTI)

In this study, the simulation and the analysis of a solar flat plate collectors combined with a compression heat pump is carried out. The system suggested must ensure the heating of a building without the recourse to an auxiliary energy source in complement of this heating system. The system is used to heat a building using heating floor. The building considered is located in Constantine-East of Algeria (Latitude 36.28 N, Longitude 6.62 E, Altitude 689m). For the calculation, the month of February was chosen, which is considered as the coldest month according to the weather data of Constantine. The performances of this system were compared to the performances of the traditional solar heating system using solar collectors and an auxiliary heating load to compensate the deficit. In this case a traditional solar heating system having the same characteristics with regard to the solar collecting area and the volume of storage tank is used. It can be concluded that the space heating system using a solar energy combined with heat pump improve the thermal performance of the heat pump and the global system. The performances of the heating system combining heat pump and solar collectors are higher than that of solar heating system with solar collectors and storage tank. The heat pump assisted by solar energy can contribute to the conservation of conventional energy and can be competitive with the traditional systems of heating.

Thermal energy storage for cooling of commercial buildings  

DOE Green Energy (OSTI)

The storage of coolness'' has been in use in limited applications for more than a half century. Recently, because of high electricity costs during utilities' peak power periods, thermal storage for cooling has become a prime target for load management strategies. Systems with cool storage shift all or part of the electricity requirement from peak to off-peak hours to take advantage of reduced demand charges and/or off-peak rates. Thermal storage technology applies equally to industrial, commercial, and residential sectors. In the industrial sector, because of the lack of economic incentives and the custom design required for each application, the penetration of this technology has been limited to a few industries. The penetration rate in the residential sector has been also very limited due to the absence of economic incentives, sizing problems, and the lack of compact packaged systems. To date, the most promising applications of these systems, therefore, appear to be for commercial cooling. In this report, the current and potential use of thermal energy storage systems for cooling commercial buildings is investigated. In addition, a general overview of the technology is presented and the applicability and cost-effectiveness of this technology for developed and developing countries are discussed. 28 refs., 12 figs., 1 tab.

DYNAMIC THERMALLY-DISCONNECTED BUILDING ENVELOPES A NEW PARADIGM FOR WALLS AND ROOFS IN LOW ENERGY BUILDINGS  

Science Conference Proceedings (OSTI)

This paper describes numerical and experimental analysis of a novel design concept. Traditionally the thermal design of building envelope assemblies is based on a static energy flow. However, building envelopes are subject to varying environmental conditions. This mismatch between the steady-state principles used in the design of roofs and walls and their dynamic operation results in relatively low thermal efficiency. Design work in support of the development of zero energy houses showed that conventional insulations may not be the most cost effective energy solution. Testing conducted on several strategies to thermally-disconnect wall and roof components showed 70% to 90% reductions in peak hour loads as compared to conventional building practice.

Field Analysis of Thermal Comfort in Two Energy Efficient Office Buildings in Malaysia  

E-Print Network (OSTI)

In recent years, there has been a growing interest to include passive concepts in buildings as a design strategy for achieving energy efficiency and optimum indoor thermal comfort in workspace as well. The paper attempts to evaluate the effectiveness of tropical passive solar control components in integrating thermal comfort with energy efficiency in office building. Field measurements are carried out in selected workspace of two office buildings that have been practiced the passive solar control. Solar radiation, air temperature, globe temperature, relative humidity and air velocity were measured for seven days including the non-working days, both indoors and outdoors for each building along with direct occupant's survey to compare the measurement and the votes of occupants under the same environment. The result shows that the thermal comfort parameters lie within the recommended comfort zone of Malaysian Standards with exception of an air movement in the workspace of both buildings. The result suggested workers' preferable condition.

Cooling Strategies Based on Indicators of Thermal Storage in Commercial Building Mass

Building thermal mass and multi-day regimes of hot weather are important, yet poorly understood, contributors to cooling energy requirements. This paper develops load-shifting sub-cooling and precooling equipment operating strategies to address a specific instance of this phenomenon, in which thermal storage by building mass over weekends exacerbates Monday cooling energy requirements. The study relies on computer simulations of energy use for a large, office building prototype in El Paso, TX using the DOE-2 building energy analysis program. The economic value of the strategies is evaluated with direct reference to utility rate schedules and a crude measure of thermal storage is related to the energy impacts of the strategies. The indicators are based on core zone air temperatures, which are sampled a t night when HVAC systems are not in use. The suggestion is made that the results and proposed strategies could be adapted for use by computerized energy management systems to reduce building energy operating costs.

Thermal Comfort of Neutral Ventilated Buildings in Different Cities  

E-Print Network (OSTI)

Although the ASHRAE 55-1992 and ISO 7730 Standards are used all over the world, many researchers have pointed out that it is impossible to maintain a uniform thermal comfort standard worldwide because of differing climate conditions. Two field thermal comfort investigations were carried out in Shanghai and Changsha. In the hot season the neutral temperature in Changsha and Shanghai is 27.5? ET* and 26.5? ET*, respectively. Compared with other cities' studies, in Beijing and Tianjin, this paper discusses thermal comfort conditions in China. The results show that thermal neutral temperature in these Chinese cities is higher than that in the ASHRAE standard. Therefore, thermal comfort temperature in China cannot directly correlate with the ASHRAE standard. This difference should be considered when designing air conditioning designing to save energy.

Thermal Performance of Building Envelope in Very Hot Dry Desert Region in Egypt (Toshky)  

E-Print Network (OSTI)

Toshky region is a desert region located in the south east of Egyptian western desert at the Tropical Cancer (23.5 N). The following features characterized this region during the summer season; aridity, high summer day time temperatures reaches to above 40 C for about 6 hours, large diurnal temperature variation, low relative humidity, and high solar radiation reaches to about 1100W/m2 on horizontal surfaces. In such climate thermal human comfort is crucial to provide the reasonable environment for the people. As the building envelop has a major role in saving comfort for people and improve the consumption of energy in building. So this study is interested in studying the thermal performance for some building constructed from different building materials as; Nobaa sandstone, hollow clay brick, light sand block, and hollow and insulated bazelt blocks. The external climatic conditions and the temperature distribution inside the wall construction and the indoor air temperature were measured. The result shows that using Nobaa sandstone alone in building is not adequate with the external climatic conditions of this region. But using building materials with specific thermal characteristics, and using thermal insulation led to reduce the heat flow through the walls and help the building to be suitable with its external environment conditions. The study also show that hollow clay brick and light sand block valid the lowest indoor air temperature, and the thermal performance of hollow bazelt blocks can be improved by using thermal insulation, Natural and forced night ventilation help the indoor environment to be within the thermal comfort.

Scenario Analysis of Peak Demand Savings for Commercial Buildings with Thermal Mass in California  

SciTech Connect

This paper reports on the potential impact of demand response (DR) strategies in commercial buildings in California based on the Demand Response Quick Assessment Tool (DRQAT), which uses EnergyPlus simulation prototypes for office and retail buildings. The study describes the potential impact of building size, thermal mass, climate, and DR strategies on demand savings in commercial buildings. Sensitivity analyses are performed to evaluate how these factors influence the demand shift and shed during the peak period. The whole-building peak demand of a commercial building with high thermal mass in a hot climate zone can be reduced by 30percent using an optimized demand response strategy. Results are summarized for various simulation scenarios designed to help owners and managers understand the potential savings for demand response deployment. Simulated demand savings under various scenarios were compared to field-measured data in numerous climate zones, allowing calibration of the prototype models. The simulation results are compared to the peak demand data from the Commercial End-Use Survey for commercial buildings in California. On the economic side, a set of electricity rates are used to evaluate the impact of the DR strategies on economic savings for different thermal mass and climate conditions. Our comparison of recent simulation to field test results provides an understanding of the DR potential in commercial buildings.

Best Practice For the Location of Air and Thermal Boundaries in Small Commercial Buildings  

E-Print Network (OSTI)

Suspended t-bar ceilings are common in commercial buildings. Research has found that these ceilings are very leaky, and several problems arise from this. If the space above the ceiling is vented to outdoors, the entire building becomes leaky. Furthermore, if the insulation is located at the ceiling rather than the roof, then the ceiling space will be hot (summer), and if the ceiling space is also vented to outdoors, then the ceiling space will be hot and humid. The thermal and humidity conditions of the ceiling space have important implications for space conditioning loads, building ventilation rates, and indoor relative humidity. Conductive gains through ductwork add to loads, and various forms of uncontrolled air flow readily move air between the ceiling space and the occupied space. These factors should be considered during design and construction of commercial buildings. Best practice: locate the air and thermal boundaries of the building at the roof deck. This approach has many benefits.

Thermal Performance Analysis of a High-Mass Residential Building  

DOE Green Energy (OSTI)

Minimizing energy consumption in residential buildings using passive solar strategies almost always calls for the efficient use of massive building materials combined with solar gain control and adequate insulation. Using computerized simulation tools to understand the interactions among all the elements facilitates designing low-energy houses. Finally, the design team must feel confident that these tools are providing realistic results. The design team for the residential building described in this paper relied on computerized design tools to determine building envelope features that would maximize the energy performance [1]. Orientation, overhang dimensions, insulation amounts, window characteristics and other strategies were analyzed to optimize performance in the Pueblo, Colorado, climate. After construction, the actual performance of the house was monitored using both short-term and long-term monitoring approaches to verify the simulation results and document performance. Calibrated computer simulations showed that this house consumes 56% less energy than would a similar theoretical house constructed to meet the minimum residential energy code requirements. This paper discusses this high-mass house and compares the expected energy performance, based on the computer simulations, versus actual energy performance.

Use of Renewable Energy in Buildings: Experiences With Solar Thermal Utilization  

E-Print Network (OSTI)

Solar energy is receiving much more attention in building energy systems in recent years. Solar thermal utilization should be based on the integration of solar collectors into buildings. The facades of buildings can be important solar collectors, and therefore become multifunctional. In addition, solar collectors can be used to enhance the appearance of the façade when considering aesthetic compatibility. Currently, the feasible approach for integration of solar collectors into buildings is to install collectors on the south tilted roofs, south walls, balconies or awnings. Experiences on solar thermal utilization are mainly introduced in this paper, which include solar hot water systems with different design methods in residential buildings and solar-powered integrated energy systems in public buildings. Then suggestions are given. In cities of China, an ideal opportunity to carry out solar renovation with roof-integrated collectors is in combination with the rebuilding of apartment roofs, from flat to inclined. With regard to multi-story residential buildings, a central hot water supply system and central-individual hot water supply system are more appropriate in view of aesthetic compatibility of solar collectors with building roof and convenience of management. As for public buildings, it is highly recommended to design solar-powered integrated energy systems for the purpose of high solar fraction.

Predictive Optimal Control of Active and Passive Building Thermal Storage Inventory  

DOE Green Energy (OSTI)

Cooling of commercial buildings contributes significantly to the peak demand placed on an electrical utility grid. Time-of-use electricity rates encourage shifting of electrical loads to off-peak periods at night and weekends. Buildings can respond to these pricing signals by shifting cooling-related thermal loads either by precooling the building's massive structure or the use of active thermal energy storage systems such as ice storage. While these two thermal batteries have been engaged separately in the past, this project investigates the merits of harnessing both storage media concurrently in the context of predictive optimal control. This topical report describes the demonstration of the model-based predictive optimal control for active and passive building thermal storage inventory in a test facility in real-time using time-of-use differentiated electricity prices without demand charges. The laboratory testing findings presented in this topical report cover the second of three project phases. The novel supervisory controller successfully executed a three-step procedure consisting of (1) short-term weather prediction, (2) optimization of control strategy over the next planning horizon using a calibrated building model, and (3) post-processing of the optimal strategy to yield a control command for the current time step that can be executed in the test facility. The primary and secondary building mechanical systems were effectively orchestrated by the model-based predictive optimal controller in real-time while observing comfort and operational constraints. The findings reveal that when the optimal controller is given imperfect weather fore-casts and when the building model used for planning control strategies does not match the actual building perfectly, measured utility costs savings relative to conventional building operation can be substantial. This requires that the facility under control lends itself to passive storage utilization and the building model includes a realistic plant model. The savings associated with passive building thermal storage inventory proved to be small be-cause the test facility is not an ideal candidate for the investigated control technology. Moreover, the facility's central plant revealed the idiosyncratic behavior that the chiller operation in the ice-making mode was more energy efficient than in the chilled-water mode. Field experimentation (Phase III) is now required in a suitable commercial building with sufficient thermal mass, an active TES system, and a climate conducive to passive storage utilization over a longer testing period to support the laboratory findings presented in this topical report.

Steel-framed buildings: Impacts of wall detail configurations on the whole wall thermal performance  

SciTech Connect

The main objective of this paper is the influence of architectural wall details on the whole wall thermal performance. Whole wall thermal performance analysis was performed for six light gage steel-framed wall systems (some with wood components). For each wall system, all wall details were simulated using calibrated 3-D finite difference computer modeling. The thermal performance of the six steel-framed wall systems included various system details and the whole wall system thermal performance for a typical single-story ranch house. Currently, predicted heat losses through building walls are typically based on measurements of the wall system clear wall area using test methods such as ASTM C 236 or are calculated by one of the procedures recommended in the ASHRAE Handbook of Fundamentals that often is carried out for the clear wall area exclusively. In this paper, clear wall area is defined as the part of the wall system that is free of thermal anomalies due to building envelope details or thermally unaffected by intersections with other surfaces of the building envelope. Clear wall experiments or calculations normally do not include the effects of building envelope details such as corners, window and door openings, and structural intersections with roofs, floors, ceilings, and other walls. In steel-framed wall systems, these details typically consist of much more structural components than the clear wall. For this situation, the thermal properties measured or calculated for the clear wall area do not adequately represent the total wall system thermal performance. Factors that would impact the ability of today`s standard practice to accurately predict the total wall system thermal performance are the accuracy of the calculation methods, the area of the total wall that is clear wall, and the quantity and thermal performance of the various wall system details.

Predictive Optimal Control of Active and Passive Building Thermal Storage Inventory  

SciTech Connect

Cooling of commercial buildings contributes significantly to the peak demand placed on an electrical utility grid. Time-of-use electricity rates encourage shifting of electrical loads to off-peak periods at night and weekends. Buildings can respond to these pricing signals by shifting cooling-related thermal loads either by precooling the building's massive structure or the use of active thermal energy storage systems such as ice storage. While these two thermal batteries have been engaged separately in the past, this project investigated the merits of harnessing both storage media concurrently in the context of predictive optimal control. To pursue the analysis, modeling, and simulation research of Phase 1, two separate simulation environments were developed. Based on the new dynamic building simulation program EnergyPlus, a utility rate module, two thermal energy storage models were added. Also, a sequential optimization approach to the cost minimization problem using direct search, gradient-based, and dynamic programming methods was incorporated. The objective function was the total utility bill including the cost of reheat and a time-of-use electricity rate either with or without demand charges. An alternative simulation environment based on TRNSYS and Matlab was developed to allow for comparison and cross-validation with EnergyPlus. The initial evaluation of the theoretical potential of the combined optimal control assumed perfect weather prediction and match between the building model and the actual building counterpart. The analysis showed that the combined utilization leads to cost savings that is significantly greater than either storage but less than the sum of the individual savings. The findings reveal that the cooling-related on-peak electrical demand of commercial buildings can be considerably reduced. A subsequent analysis of the impact of forecasting uncertainty in the required short-term weather forecasts determined that it takes only very simple short-term prediction models to realize almost all of the theoretical potential of this control strategy. Further work evaluated the impact of modeling accuracy on the model-based closed-loop predictive optimal controller to minimize utility cost. The following guidelines have been derived: For an internal heat gain dominated commercial building, reasonable geometry simplifications are acceptable without a loss of cost savings potential. In fact, zoning simplification may improve optimizer performance and save computation time. The mass of the internal structure did not show a strong effect on the optimization. Building construction characteristics were found to impact building passive thermal storage capacity. It is thus advisable to make sure the construction material is well modeled. Zone temperature setpoint profiles and TES performance are strongly affected by mismatches in internal heat gains, especially when they are underestimated. Since they are a key factor in determining the building cooling load, efforts should be made to keep the internal gain mismatch as small as possible. Efficiencies of the building energy systems affect both zone temperature setpoints and active TES operation because of the coupling of the base chiller for building precooling and the icemaking TES chiller.

The effect of simplifying the building description on the numerical modeling of its thermal performance  

SciTech Connect

A thermal building simulation program is a numerical model that calculates the response of the building envelopes to weather and human activity, simulates dynamic heating and cooling loads, and heating and cooling distribution systems, and models building equipment operation. The scope of the research is to supply the users of such programs with information about the dangers and benefits of simplifying the input to their models. The Introduction describes the advantages of modeling the heat transfer mechanisms in a building. The programs that perform this type of modeling have, however, limitations. The user is therefore often put in the situation of simplifying the floor plans of the building under study, but not being able to check the effects that this approximation introduces in the results of the simulation. Chapter 1 is a description of methods. It also introduces the floor plans for the office building under study and the ``reasonable`` floor plans simplifications. Chapter 2 presents DOE-2, the thermal building simulation program used in the sensitivity study. The evaluation of the accuracy of the DOE-2 program itself is also presented. Chapter 3 contains the sensitivity study. The complicated nature of the process of interpreting the temperature profile inside a space leads to the necessity of defining different building modes. The study compares the results from the model of the detailed building description with the results from the models of the same building having simplified floor plans. The conclusion is reached that a study of the effects of simplifying the floor plans of a building is important mainly for defining the cases in which this approximation is acceptable. Different results are obtained for different air conditioning/load regimes of the building. 9 refs., 24 figs.

Computational Identification of Thermal Technical Properties of Building Materials and its Reliability  

SciTech Connect

Reliable computational analysis of heat transfer in building materials needs realistic input data. New building constructions contain advanced composite materials whose macroscopic thermal technical (both insulation and accumulation) properties should be identified properly, following all available qualitative results from their microstructural analysis. However, the corresponding inverse problems are much more complicated than the original direct ones. The paper demonstrates the mathematical and computational support for the identification of basic thermal technical characteristics using certain class of inexpensive primary non-stationary measurement devices, including the uncertainty analysis of measurements.

The integration of water loop heat pump and building structural thermal storage systems  

SciTech Connect

Many commercial buildings need heat in one part and, at the same time, cooling in another part. Even more common is the need for heating during one part of the day and cooling during another in the same spaces. If that energy could be shifted or stored for later use, significant energy might be saved. If a building's heating and cooling subsystems could be integrated with the building's structural mass and used to collect, store, and deliver energy, the energy might be save cost-effectively. To explore this opportunity, researchers at the Pacific Northwest Laboratory (PNL) examined the thermal interactions between the heating, ventilating, and air-conditioning (HVAC) system and the structure of a commercial building. Computer models were developed to simulate the interactions in an existing building located in Seattle, Washington, to determine how these building subsystems could be integrated to improve energy efficiency. The HVAC subsystems in the existing building were modeled. These subsystems consist of decentralized water-source heat pumps (WSHP) in a closed water loop, connected to cooling towers for heat rejection during cooling mode and boilers to augment heating. An initial base case'' computer model of the Seattle building, as-built, was developed. Metered data available for the building were used to calibrate this model to ensure that the analysis would provide information that closely reflected the operation of a real building. The HVAC system and building structure were integrated in the model using the concrete floor slabs as thermal storage media. The slabs may be actively charged during off-peak periods with the chilled water in the loop and then either actively or passively discharged into the conditioned space during peak periods. 21 refs., 37 figs., 17 tabs.

Demand Shifting With Thermal Mass in Large Commercial Buildings:Field Tests, Simulation and Audits  

SciTech Connect

The principle of pre-cooling and demand limiting is to pre-cool buildings at night or in the morning during off-peak hours, storing cooling in the building thermal mass and thereby reducing cooling loads and reducing or shedding related electrical demand during the peak periods. Cost savings are achieved by reducing on-peak energy and demand charges. The potential for utilizing building thermal mass for load shifting and peak demand reduction has been demonstrated in a number of simulation, laboratory, and field studies (Braun 1990, Ruud et al. 1990, Conniff 1991, Andresen and Brandemuehl 1992, Mahajan et al. 1993, Morris et al. 1994, Keeney and Braun 1997, Becker and Paciuk 2002, Xu et al. 2003). This technology appears to have significant potential for demand reduction if applied within an overall demand response program. The primary goal associated with this research is to develop information and tools necessary to assess the viability of and, where appropriate, implement demand response programs involving building thermal mass in buildings throughout California. The project involves evaluating the technology readiness, overall demand reduction potential, and customer acceptance for different classes of buildings. This information can be used along with estimates of the impact of the strategies on energy use to design appropriate incentives for customers.

Thermal Integrity Assessment of Building Envelopes of Experimental Houses Using Infrared Thermography  

Science Conference Proceedings (OSTI)

Zero Energy Building Research Alliance, or ZEBRAlliance, is a joint DOE-ORNL-construction industry initiative to develop and demonstrate new energy efficiency technologies for residential buildings, as well as fine-tune and integrate existing technologies, to lower energy costs. Construction of residential envelopes, the diaphragms that separate the inside from outdoors, can have enormous impact on whole-building energy usage. Consequently, post-construction thermal integrity assessment of the building envelopes in the experimental ZEBRAlliance homes is an integral part of the research and development cycle. Nondestructive infrared (IR) thermography provides a relatively easy and quick means of inspecting the experimental homes for thermal bridging, insulation imperfections, moisture penetration, air leakage, etc. Two experimental homes located in Oak Ridge, TN were inspected using IR thermography. The homes are designed with two different envelope systems: (i) Structural Insulated Panels (SIP home) consisting of an insulating foam core sandwiched between oriented strand boards, and (ii) Optimal Value Framing (OVF home) using innovatively spaced wood studs, which are designed to minimize the amount of wood framing, reduce thermal bridging, and lower material costs. IR thermal imaging was performed from both outside and inside of the homes. In this paper, IR images of roof and wall sections of the homes are presented and discussed with respect to identification of areas of thermal bridging and any insulation deficiencies.

Shifting with Thermal Mass in Large Commercial Buildings in a Shifting with Thermal Mass in Large Commercial Buildings in a California Hot Climate Zone Title Demand Shifting with Thermal Mass in Large Commercial Buildings in a California Hot Climate Zone Publication Type Report LBNL Report Number LBNL-3898e Year of Publication 2009 Authors Xu, Peng, Rongxin Yin, Carrie Brown, and DongEun Kim Date Published June 2009 Publisher CEC/LBNL Keywords demand response, demand shifting (pre-cooling), DRQAT, hot climates, market sectors, office buildings, pre-cooling, technologies, testbed tools and guides, thermal mass Abstract The potential for using building thermal mass for load shifting and peak energy demand reduction has been demonstrated in a number of simulation, laboratory, and field studies. Previous Lawrence Berkeley National Laboratory research has demonstrated that the approach is very effective in cool and moderately warm climate conditions (California Climate Zones 2-4). However, this method had not been tested in hotter climate zones.This project studied the potential of pre-cooling the building early in the morning and increasing temperature setpoints during peak hours to reduce cooling-related demand in two typical office buildings in hotter California climates - one in Visalia (CEC Climate Zone 13) and the other in San Bernardino (CEC Climate Zone 10). The conclusion of the work to date is that pre-cooling in hotter climates has similar potential to that seen previously in cool and moderate climates. All other factors being equal, results to date indicate that pre-cooling increases the depth (kW) and duration (kWh) of the possible demand shed of a given building. The effectiveness of night pre-cooling in typical office building under hot weather conditions is very limited. However, night pre-cooling is helpful for office buildings with an undersized HVAC system. Further work is required to duplicate the tests in other typical buildings and in other hot climate zones and prove that pre-cooling is truly effective.

The integration of water loop heat pump and building structural thermal storage systems  

SciTech Connect

Commercial buildings often have extensive periods where one space needs cooling and another heating. Even more common is the need for heating during one part of the day and cooling during another in the same spaces. If a building's heating and cooling system could be integrated with the building's structural mass such that the mass can be used to collect, store, and deliver energy, significant energy might be saved. Computer models were developed to simulate this interaction for an existing office building in Seattle, Washington that has a decentralized water-source heat pump system. Metered data available for the building was used to calibrate a base'' building model (i.e., nonintegrated) prior to simulation of the integrated system. In the simulated integration strategy a secondary water loop was manifolded to the main HVAC hydronic loop. tubing in this loop was embedded in the building's concrete floor slabs. Water was routed to this loop by a controller to charge or discharge thermal energy to and from the slabs. The slabs were also in thermal communication with the conditioned spaces. Parametric studies of the building model, using weather data for five other cities in addition to Seattle, predicted that energy can be saved on cooling dominated days. On hot, dry days and during the night the cooling tower can beneficially be used as a free cooling'' source for thermally charging'' the floor slabs using cooled water. Through the development of an adaptive/predictive control strategy, annual HVAC energy savings as large as 30% appear to be possible in certain climates. 8 refs., 13 figs.

Equilibrium thermal characteristics of a building integrated photovoltaic tiled roof  

SciTech Connect

Photovoltaic (PV) modules attain high temperatures when exposed to a combination of high radiation levels and elevated ambient temperatures. The temperature rise can be particularly problematic for fully building integrated PV (BIPV) roof tile systems if back ventilation is restricted. PV laminates could suffer yield degradation and accelerated aging in these conditions. This paper presents a laboratory based experimental investigation undertaken to determine the potential for high temperature operation in such a BIPV installation. This is achieved by ascertaining the dependence of the PV roof tile temperature on incident radiation and ambient temperature. A theory based correction was developed to account for the unrealistic sky temperature of the solar simulator used in the experiments. The particular PV roof tiles used are warranted up to an operational temperature of 85 C, anything above this temperature will void the warranty because of potential damage to the integrity of the encapsulation. As a guide for installers, a map of southern Europe has been generated indicating locations where excessive module temperatures might be expected and thus where installation is inadvisable. (author)

Proposed simplified methods for predicting thermal behaviour and energy consumption of buildings. Technical memo  

SciTech Connect

The paper which is based on the exhaustive measurements taken to assess the energy requirements and the associated thermal comfort of a large hotel in Scotland shows that while bulk metering can provide an indication of building and system performance, the only reliable way to assess thermal performance is to undertake an energy audit on a microscopic level. Such an audit should be part of a continuous monitoring program and may be used to provide the necessary date from which a simple model of the building may be constructed. From the analysis presented, general laws governing the energy requirements for process, meeting building heat loss and maintaining services, etc. are expressed in simple forms for monitoring purposes.

Interaction of a solar space heating system with the thermal behavior of a building  

DOE Green Energy (OSTI)

The thermal behavior of a building in response to heat input from an active solar space heating system is analyzed to determine the effect of the variable storage tank temperature on the cycling rate, on-time, and off-time of a heating cycle and on the comfort characteristics of room air temperature swing and of offset of the average air temperature from the setpoint (droop). A simple model of a residential building, a fan coil heat-delivery system, and a bimetal thermostat are used to describe the system. A computer simulation of the system behavior has been developed and verified by comparisons with predictions from previous studies. The system model and simulation are then applied to determine the building response to a typical hydronic solar heating system for different solar storage temperatures, outdoor temperatures, and fan coil sizes. The simulations were run only for those cases where there was sufficient energy from storage to meet the building load requirements.

Research on the Effect of a Planting Roof on the Thermal Load of a Business Building  

E-Print Network (OSTI)

A pair of comparative testing rooms (one with an ordinary roof and the other with a planting roof) was established in our laboratory, and in- situ measurement (in summer) data have been collected and treated. The indoor thermal environment was analyzed and the thermal load within each room was calculated Comparative analysis of thermal loads of these two rooms was done. Reduction of thermal load by the planting roof is clearly shown from our research work. A theoretical analysis of the effect of the planting roof on the room's thermal load was done, and theoretical relations between outdoor air temperature and indoor thermal load within certain region were established. The feasibility analysis of the application of our research work to the business building was also completed. The summer cooling load reduction characteristics, the energy saving characteristics on air conditioning system, the yearly electricity consumption reduction, the yearly consumption amount reduction of “Primary Energy”, the discharge amount reduction of sensible heat to outdoor atmosphere in summer, and the yearly discharge amount reduction of greenhouse gases to the outdoor atmosphere from air conditioning system due to the planting roof are also predicted. A corresponding economic analysis is also presented in this paper. The results show the advantages of the planting roof, and also promote the widespread application of the planting roof to business buildings.

BEETIT Project: Georgia Tech is using innovative components and system design to develop a new type of absorption heat pump. Georgia Tech’s new heat pumps are energy efficient, use refrigerants that do not emit greenhouse gases, and can run on energy from combustion, waste heat, or solar energy. Georgia Tech is leveraging enhancements to heat and mass transfer technology possible in microscale passages and removing hurdles to the use of heat-activated heat pumps that have existed for more than a century. Use of microscale passages allows for miniaturization of systems that can be packed as monolithic full-system packages or discrete, distributed components enabling integration into a variety of residential and commercial buildings. Compared to conventional heat pumps, Georgia Tech’s design innovations will create an absorption heat pump that is much smaller, has higher energy efficiency, and can also be mass produced at a lower cost and assembly time.

Evaluation of Demand Shifting with Thermal Mass in Two Large Commercial Buildings  

SciTech Connect

Building thermal mass can be used to reduce the peak cooling load. For example, in summer, the building mass can be pre-cooled during non-peak hours in order to reduce the cooling load in the peak hours. As a result, the cooling load is shifted in time and the peak demand is reduced. The building mass can be cooled most effectively during unoccupied hours because it is possible to relax the comfort constraints. While the benefits of demand shift are certain, different thermal mass discharge strategies result in different cooling load reduction and savings. The goal of an optimized discharge strategy is to maximize the thermal mass discharge and minimize the possibility of rebounds before the shed period ends. A series of filed tests were carefully planned and conducted in two commercial buildings in Northern California to investigate the effects of various precooling and demand shed strategies. Field tests demonstrated the potential of cooling load reduction in peak hours and importance of discharge strategies to avoid rebounds. EnergyPlus simulation models were constructed and calibrated to investigate different kind of recovery strategies. The results indicate the value of pre-cooling in maximizing the electrical shed in the on-peak period. The results also indicate that the dynamics of the shed need to be managed in order to avoid discharging the thermal capacity of the building too quickly, resulting in high cooling load and electric demand before the end of the shed period. An exponential trajectory for the zone set-point during the discharge period yielded good results and is recommended for practical implementation.

Building Design and Operation for Improving Thermal Comfort in Naturally Ventilated Buildings in a Hot-Humid Climate  

E-Print Network (OSTI)

The goal of this research was to develop new techniques for designing and operating unconditioned buildings in a hot-humid climate that could contribute to an improvement of thermal performance and comfort condition. The recommendations proposed in this research will also be useful for facility managers on how to maintain unconditioned buildings in this climate. This study investigated two unconditioned Thai Buddhist temples located in the urban area of Bangkok, Thailand. One is a 100-year-old, high-mass temple. The other is a 5-year-old, lower-mass temple. The indoor measurements revealed that the thermal condition inside both temples exceed the ASHRAE-recommended comfort zone. Surprisingly, the older temple maintained a more comfortable indoor condition due to its thermal inertia, shading, and earth contacts. A baseline thermal and airflow model of the old temple was established using a calibrated computer simulation method. To accomplish this, HEATX, a 3-D Computational Fluid Dynamics (CFD) code, was coupled with the DOE-2 thermal simulation program. HEATX was used to calculate the airflow rate and the surface convection coefficients for DOE-2, and DOE-2 was used to provide physical input variables to form the boundary conditions for HEATX. In this way calibrated DOE-2/CFD simulation model was accomplished, and the baseline model was obtained. To investigate an improved design, four design options were studied: 1) a reflective or low-solar absorption roof, 2) R-30 ceiling insulation, 3) shading devices, and 4) attic ventilation. Each was operated using three modes of ventilation. The low-absorption roof and the R-30 ceiling insulation options were found to be the most effective options, whereas the shading devices and attic ventilation were less effective options, regardless of which ventilation mode was applied. All design options performed much better when nighttime-only ventilation was used. Based on this analysis, two prototype temples was proposed (i.e., low-mass and high-mass temples). From the simulation results of the two prototypes, design and operation guidelines are proposed, which consist of: 1) increased wall and ceiling insulation, 2) white-colored, low-absorption roof, 3) slab-on-ground floor, 4) shading devices, 5) nighttime-only ventilation, 6) attic ventilation, and 7) wider openings to increase the natural ventilation air flow windows, wing walls, and vertical fins.

The Analysis of Dynamic Thermal Performance of Insulated Wall and Building Cooling Energy Consumption in Guangzhou  

E-Print Network (OSTI)

The summer in Guangzhou, China, is hot and long. Heat proofing is very important for the energy efficiency of buildings and improvement of the indoor thermal environment. The residential buildings in the southern region are cooled by air conditioning mainly with the increase of the live level. This study investigates the influence of the thermal dynamic performance on the yearly cooling load and yearly maximum cooling demand in typical residential flats by employing KVALUE and DeST. The simulation predictions indicate that reductions in the cooling load and maximum cooling demand are obtained when the insulation is added in the wall, but the potential of energy saving is quite limited when the wall only is insulated.

Thermally Activated Cooling: A Regional Approach for EstimatingBuilding Adoption  

SciTech Connect

This paper examines the economic potential for thermally-activated cooling (TAC) technologies as a component of distributed energy resource (DER) systems in California. A geographic information system (GIS) is used to assess the regional variation of TAC potential and to visualize the geographic pattern of potential adoption. The economic potential and feasibility of DER systems in general, and especially TAC, is highly dependent on regional factors such as retail electricity rates, building cooling loads, and building heating loads. Each of these factors varies with location, and their geographic overlap at different sites is an important determinant in a market assessment of DER and TAC. This analysis uses system payback period as the metric to show the regional variation of TAC potential in California office buildings. The DER system payback with and without TAC is calculated for different regions in California using localized values of retail electricity rates and the weather-dependent variation in building cooling and heating loads. This GIS-based method has numerous applications in building efficiency studies where geographically dependent variables, such as space cooling and heating energy use, play an important role.

A Study on Zoning Regulations' Impact on Thermal Comfort Conditions in Non-conditioned Apartment Buildings in Dhaka City  

E-Print Network (OSTI)

Unfavorable thermal comfort conditions are common in the non-conditioned apartment buildings typical of Dhaka (Ali, 2007; Hafiz, 2004). Causes behind such unfavorable thermal comfort conditions include (but are not limited to) Dhaka?s climate, microclimate in Dhaka's typical residential neighborhood, its socio-economic context, housing type, and its inadequate planning regulations. Dhaka's climate is hot humid but it can be tackled with well designed buildings as well as well as designed neighborhoods, both of which demands ample open space. However, due to land scarcity and high population density, building developments lack open spaces and that results in unfavorable thermal comfort conditions in apartment buildings. Dhaka?s previous zoning regulations were unable to control this dense development, and therefore, a new set of zoning regulations were enacted (2008). However, no post-evaluation study was conducted to research the effect of this new set of regulations. The intention of this research is to first evaluate the existing regulations, and second, to suggest appropriate zoning regulation schemes for Dhaka's non-conditioned apartment buildings (for a lot size of 1/3 acre), which would provide favorable thermal comfort conditions without changing its existing density. To accomplish the first goal, this research analyzed two existing zoning schemes (one based on regulations of 1996, and the other based on the regulations of 2008). To accomplish the second goal, this research analyzed two hypothetical zoning schemes. The hypothetical ones were studied because this research finds 1996 and 2008 regulations to be two extremes (in terms of allowing open space and building height), and therefore examination of in-between alternative zoning schemes seemed essential for this study. To analyze the four zoning regulation schemes' impact on thermal comfort in apartment buildings, four sets of built environment were created in EnergyPlus (Energy Simulation software) as well as in Fluent (Computational Fluid Dynamics software). Each set of built environment is a cluster of nine buildings; and each set is different from each other in terms of their building footprints and building heights. The building on the center was modeled implicitly, and remaining buildings were modeled as solid blocks (to act as neighboring buildings) for blocking sun and wind. The ES and CFD software simulated possible solar, daylight, and wind availability inside the central building, and consequently produce data on thermal comfort conditions, namely indoor temperature and air velocity. The simulation results were compared to see which zoning schemes provided the most favorable thermal comfort conditions. This research found one of the in-between schemes (60% allowable footprint, 9-story height limit) to be more appropriate in terms of thermal comfort conditions than the other three schemes; because it provides better solar protection and better natural ventilation and consequently it reduces indoor temperature and increases indoor air velocity.

Effect of insulation location on initial transient thermal response of building walls  

E-Print Network (OSTI)

ABSTRACT: The effect of insulation location on the heat transfer characteristics of building wall elements under initial transient conditions is studied. Thermal performance with an insulation layer placed on the inside of a wall is compared to that when the insulation layer is placed on the outside. The investigation is carried out for the climatic conditions of Riyadh, Saudi Arabia, during representative days for July and January using a finite-volume implicit procedure. The initial temperature distribution across the wall is assumed to be uniform and equal to the daily mean external air temperature. The numerical model is validated against a semi-analytic solution developed for a simple test case. The results of model application under the present conditions show that placing the insulation on the inside gives an instantaneous load that is about 20 % of the value for outside insulation during the first few hours in the initial transient process. Besides, the duration of the transient process which leads to steady periodic state, and thus, the period of thermal discomfort due to radiation exchange is much shorter for the inside insulation. The average heat transmission over the first 24 hours

Assessment of extent and degree of thermal damage to polymeric materials in the Three Mile Island Unit 2 Reactor building  

DOE Green Energy (OSTI)

This paper describes assumptions and procedures used to perform thermal damage analysis caused by post loss-of-coolant-accident (LOCA) hydrogen deflagration at Three Mile Island Unit 2 Reactor. Examination of available photographic evidence yields data on the extent and range of thermal and burn damage. Thermal damage to susceptible material in accessible regions of the reactor building was distributed in non-uniform patterns. No clear explanation for non-uniformity was found in examined evidence, e.g., burned materials were adjacent to materials that appear similar but were not burned. Because these items were in proximity to vertical openings that extend the height of the reactor building, we assume the unburned materials preferentially absorbed water vapor during periods of high, local steam concentration. A control pendant from the polar crane located in the top of the reactor building sustained asymmetric burn damage of decreasing degree from top to bottom. Evidence suggests the polar-crane pendant side that experienced heaviest damage was exposed to intense radiant energy from a transient fire plume in the reactor containment volume. Simple hydrogen-fire-exposure tests and heat transfer calculations approximate the degree of damage found on inspected materials from the containment building and support for an estimated 8% pre-fire hydrogen.

Thermal energy storage for building heating and cooling applications. Quarterly progress report, April--June 1976  

DOE Green Energy (OSTI)

This is the first in a series of quarterly progress reports covering activities at ORNL to develop thermal energy storage (TES) technology applicable to building heating and cooling. Studies to be carried out will emphasize latent heat storage in that sensible heat storage is held to be an essentially existing technology. Development of a time-dependent analytical model of a TES system charged with a phase-change material was started. A report on TES subsystems for application to solar energy sources is nearing completion. Studies into the physical chemistry of TES materials were initiated. Preliminary data were obtained on the melt-freeze cycle behavior and viscosities of sodium thiosulfate pentahydrate and a mixture of Glauber's salt and Borax; limited melt-freeze data were obtained on two paraffin waxes. A subcontract was signed with Monsanto Research Corporation for studies on form-stable crystalline polymer pellets for TES; subcontracts are being negotiated with four other organizations (Clemson University, Dow Chemical Company, Franklin Institute, and Suntek Research Associates). Review of 10 of 13 unsolicited proposals received was completed by the end of June 1976.

NREL Evaluates the Thermal Performance of Uninsulated Walls to Improve the Accuracy of Building Energy Simulation Tools (Fact Sheet)  

SciTech Connect

This technical highlight describes NREL research to develop models of uninsulated wall assemblies that help to improve the accuracy of building energy simulation tools when modeling potential energy savings in older homes. Researchers at the National Renewable Energy Laboratory (NREL) have developed models for evaluating the thermal performance of walls in existing homes that will improve the accuracy of building energy simulation tools when predicting potential energy savings of existing homes. Uninsulated walls are typical in older homes where the wall cavities were not insulated during construction or where the insulating material has settled. Accurate calculation of heat transfer through building enclosures will help determine the benefit of energy efficiency upgrades in order to reduce energy consumption in older American homes. NREL performed detailed computational fluid dynamics (CFD) analysis to quantify the energy loss/gain through the walls and to visualize different airflow regimes within the uninsulated cavities. The effects of ambient outdoor temperature, radiative properties of building materials, and insulation level were investigated. The study showed that multi-dimensional airflows occur in walls with uninsulated cavities and that the thermal resistance is a function of the outdoor temperature - an effect not accounted for in existing building energy simulation tools. The study quantified the difference between CFD prediction and the approach currently used in building energy simulation tools over a wide range of conditions. For example, researchers found that CFD predicted lower heating loads and slightly higher cooling loads. Implementation of CFD results into building energy simulation tools such as DOE2 and EnergyPlus will likely reduce the predicted heating load of homes. Researchers also determined that a small air gap in a partially insulated cavity can lead to a significant reduction in thermal resistance. For instance, a 4-in. tall air gap (Figure 1a) led to a 15% reduction in resistance. Similarly, a 2-ft tall air gap (Figure 1c) led to 54% reduction in thermal resistance. NREL researchers plan to extend this study to include additional wall configurations, and also to evaluate the performance of attic spaces with different insulation levels. NREL's objective is to address each potential issue that leads to inaccuracies in building energy simulation tools to improve the predictions.

Thermal Comfort Study in a Naturally Ventilated Residential Building in a Tropical Hot-Humid Climate Region  

E-Print Network (OSTI)

This paper presents a thermal comfort study in a naturally ventilated residential building located in a tropical hot-humid climate region. The specific objective of this study is to investigate whether thermal comfort in this house can be achieved through a passive system only. The methods used in this study included conducting hourly monitoring of the temperature and relative humidity; measuring the air velocities; and assessing occupants' thermal sensations through questionnaires and interview. The data from the questionnaires were matched to the monitored data to assess the acceptable range of comfortable condition. Then using an hourly simulation program, some components of the building were also "modified" to investigate whether the building can be made "more comfortable". This study shows that it is possible to provide a thermally comfortable space in this region without using mechanical air-conditioning systems. The occupants' acceptable range of comfortable condition is different than that of people in the northern latitudes. The occupants sensed "neutrality" when the operative temperature in the house was about 27 degree Celsius (80°F). The occupants could also tolerate slightly warm conditions, that is up to 29 degree Celsius (84OF), and still never wanted to install any air-conditioning systems. The simulation showed that using light wall materials would result in cooler indoor temperature at night but warmer during the day. If all windows were opened (25% the total floor area) the house could be more comfortable at night but less comfortable during the day. Findings of this study are important for architects and engineers in designing comfortable living spaces in these regions.

A solar thermal cooling and heating system for a building: Experimental and model based performance analysis and design  

Science Conference Proceedings (OSTI)

A solar thermal cooling and heating system at Carnegie Mellon University was studied through its design, installation, modeling, and evaluation to deal with the question of how solar energy might most effectively be used in supplying energy for the operation of a building. This solar cooling and heating system incorporates 52 m{sup 2} of linear parabolic trough solar collectors; a 16 kW double effect, water-lithium bromide (LiBr) absorption chiller, and a heat recovery heat exchanger with their circulation pumps and control valves. It generates chilled and heated water, dependent on the season, for space cooling and heating. This system is the smallest high temperature solar cooling system in the world. Till now, only this system of the kind has been successfully operated for more than one year. Performance of the system has been tested and the measured data were used to verify system performance models developed in the TRaNsient SYstem Simulation program (TRNSYS). On the basis of the installed solar system, base case performance models were programmed; and then they were modified and extended to investigate measures for improving system performance. The measures included changes in the area and orientation of the solar collectors, the inclusion of thermal storage in the system, changes in the pipe diameter and length, and various system operational control strategies. It was found that this solar thermal system could potentially supply 39% of cooling and 20% of heating energy for this building space in Pittsburgh, PA, if it included a properly sized storage tank and short, low diameter connecting pipes. Guidelines for the design and operation of an efficient and effective solar cooling and heating system for a given building space have been provided. (author)

Corrosiveness of wet residential building thermal insulation---Mechanisms and evaluation of electrochemical methods for assessing corrosion behavior  

SciTech Connect

An evaluation has been made of the corrosiveness of selected wet residential building thermal insulation materials in contact with low carbon steel. Investigations were conducted both in wet insulations and in filtered leachates from insulations derived from thirteen cellulosic, three mineral fiber and four foam products. Potentiodynamic polarization measurements are reported from which the overall corrosion response was assessed and then the techniques of Tafel and polarization resistance analysis applied to estimate corrosion rates. Corrosion rates were also estimated electrochemically using a direct reading instrument which performs the rate calculation based on the polarization resistance principle. Direct determinations of corrosion rate were based on weight loss measurements.

Thermal efficiency standards and codes. Volume 2. Relationships of ASHRAE standards and external factors to energy efficient building practices in new homes  

Science Conference Proceedings (OSTI)

Available data on 1976 and 1979 new home construction practices were used to develop measures of average building practice for each of the 48 contiguous states. Four possible views of the function and purpose of building energy standards and codes were posited and used to guide the search for relationships between building practice and building energy codes and standards implemented by the states. It was found that the average thermal efficiency of new single family homes improved from 1976 to 1979 in each of the 48 states. It was observed that by 1979 the average thermal efficiency of new homes in each of the 48 states exceeded American Society of Heating, Refrigerating and Air Conditioning Engineers Standard 90-75 (ASHRAE 90). However, in all states, there were substantial numbers of new homes which did not meet the Standard. By January 1, 1979, 23 states had some type of applicable building energy code or standard in effect; 11 of these had state-wide mandatory codes. All codes and standards were either identical to or very similar to the ASHRAE Standard 90-75 in their building shell requirements. A search for statistical evidence of a relationship between state building code activities and building practice was performed. Three marginally significant relationships were found by analysis of variance; however, these relationships were not significant in regression equations with socio-economic variables present. The conclusion here is that the effects of state building code actions on building practices were not detectable by the statistical methods used.

Photovoltaic and solar-thermal technologies in residential building codes, tackling building code requirements to overcome the impediments to applying new technologies  

SciTech Connect

This report describes the building code requirements and impediments to applying photovoltaic (PV) and solar-thermal technologies in residential buildings (one- or two-family dwellings). It reviews six modern model building codes that represent the codes to be adopted by most locations in the coming years: International Residential Code, First Draft (IRC), International Energy Conservation Code (IECC), International Mechanical Code (IMC), International Plumbing Code (IPC), International Fuel Gas Code (IFGC), and National Electrical Code (NEC). The IRC may become the basis for many of the building codes in the United States after it is released in 2000, and it references the other codes that will also likely become applicable at that time. These codes are reviewed as they apply to photovoltaic systems in buildings and building-integrated photovoltaic systems and to active-solar domestic hot-water and space-heating systems. The first discussion is on general code issues that impact the s e technologies-for example, solar access and sustainability. Then, secondly, the discussion investigates the relationship of the technologies to the codes, providing examples, while keeping two major issues in mind: How do the codes treat these technologies as building components? and Do the IECC and other codes allow reasonable credit for the energy impacts of the technologies? The codes can impact the implementation of the above technologies in several ways: (1) The technology is not mentioned in the codes. It may be an obstacle to implementing the technology, and the solution is to develop appropriate explicit sections or language in the codes. (2) The technology is discussed by the codes, but the language is confusing or ambiguous. The solution is to clarify the language. (3) The technology is discussed in the codes, but the discussion is spread over several sections or different codes. Practitioners may not easily find all of the relevant material that should be considered. The so lution is to put all relevant information in one section or to more clearly reference relevant sections. (4) The technology is prohibited by the code. Examples of this situation were not found. However, energy credit for some technologies cannot be achieved with the requirements of these codes. Finally, four types of future action are recommended to make the codes reviewed in this report more accommodating to renewable energy technologies: (1) Include suggested language additions and changes in the codes; (2) Create new code sections that place all of the requirements for a technology in one section of an appropriate code; (3) Apply existing standards, as appropriate, to innovative renewable energy and energy conservation technologies; and (4) Develop new standards, as necessary, to ease code compliance. A synergy may be possible in developing suitable code language changes for both photovoltaic and solar hot-water systems. The installation of rooftop photovoltaic panels and solar hot- water collectors involves many overlapping issues. Roof loading, weather tightness, mounting systems, roof penetrations, and similar concerns are identical for both technologies. If such work can be coordinated, organizations supporting both technologies could work together to implement the appropriate revisions and additions to the codes.

Real-Time Forcast Model Analysis of Daily Average Building Load for a Thermal Storage System Control  

E-Print Network (OSTI)

Thermal storage systems were originally designed to shift the on-peak cooling production to off-peak cooling production to reduce the on-peak demand. Based on the current electricity charging structure, the reduction of both on-peak and off-peak demands is becoming an exceedingly important issue. Reduction of both on-peak and off-peak demands can also extend the life span and defer or eliminate the replacement of power transformers due to potential shortage of building power capacity with anticipated equipment load increases. The next day daily average electricity demand is a critical set point to operate chillers and associated pumps at the appropriate time. For this paper, a mathematic analysis was conducted for annual daily average cooling of a building and three real-time building load forecasting models were developed. They are first-order autogressive model, random walk model and linear regression model. Finally, the comparison of results show the random walk model provides the best forecast.

Thermal Performance of Unvented Attics in Hot-Dry Climates: Results from Building America; Preprint  

DOE Green Energy (OSTI)

Unvented attics have become a more common design feature implemented by Building America partners in hot-dry climates of the United States. More attention is being focused on how this approach affects heating and cooling energy consumption. By eliminating the ridge and eave vents that circulate outside air through the attic and by moving the insulation from the attic floor to the underside of the roof, an unvented attic become a semi-conditioned space, creating a more benign environment for space conditioning ducts.

Distributed Energy Resources On-Site Optimization for Commercial Buildings with Electric and Thermal Storage Technologies  

SciTech Connect

The addition of storage technologies such as flow batteries, conventional batteries, and heat storage can improve the economic as well as environmental attractiveness of on-site generation (e.g., PV, fuel cells, reciprocating engines or microturbines operating with or without CHP) and contribute to enhanced demand response. In order to examine the impact of storage technologies on demand response and carbon emissions, a microgrid's distributed energy resources (DER) adoption problem is formulated as a mixed-integer linear program that has the minimization of annual energy costs as its objective function. By implementing this approach in the General Algebraic Modeling System (GAMS), the problem is solved for a given test year at representative customer sites, such as schools and nursing homes, to obtain not only the level of technology investment, but also the optimal hourly operating schedules. This paper focuses on analysis of storage technologies in DER optimization on a building level, with example applications for commercial buildings. Preliminary analysis indicates that storage technologies respond effectively to time-varying electricity prices, i.e., by charging batteries during periods of low electricity prices and discharging them during peak hours. The results also indicate that storage technologies significantly alter the residual load profile, which can contribute to lower carbon emissions depending on the test site, its load profile, and its adopted DER technologies.

Sensitivity analysis of window characteristics and their interactions on thermal performance in residential buildings  

E-Print Network (OSTI)

This thesis studies the effects of different window characteristics such as area, conductance and shading on annual energy performance in residential buildings. A single parameter analysis is used to quantify the effect on annual energy due to a change in an individual parameter. However misconceptions about these effects (without regard to the values of the other parameters of the window) lead to predictions that overestimate or underestimate actual savings by neglecting interactions that exist between the parameters. The effect of interactions of two parameter changes is determined in this study using a two parameter analysis technique. This technique uses the difference between changes in annual energy of a parameter at different values of an associated parameter to determine the importance of the interaction effect between the parameters. This interaction effect is used as a measure to determine the important two parameter changes in different orientations for six different climates. The interactions were shown to have significant effects on predicted energy reductions in the six climates studied.

Evaluation of the Heating & Cooling Energy Demand of a Case Residential Building by Comparing The National Calculation Methodology of Turkey and EnergyPlus through Thermal Capacity Calculations  

E-Print Network (OSTI)

In all around the world, because of the rapid population growth and exhausting energy sources over time, energy efficiency and energy conservation gradually come into prominence. Hence, in 2002, a directive (EPBD) which obligates reducing energy usage and energy performance in buildings was published by European Union. In this scope, Turkey has developed a National Building Energy Performance Calculation Methodology, BepTr, which is based on simple hourly method in ISO EN 13790 Umbrella Document to determine the energy performance of buildings. The aim of the paper is to display the energy demand differences resultant from only the envelope’s thermal capacity between simplified method which is projected in ISO EN 13790 Umbrella Document and EnergyPlus which is based on full dynamic simulation method.

Theoretical and Experimental Thermal Performance Analysis of Building Shell Components Containing Blown Fiber Glass Insulation Enhanced with Phase Change Material (PCM)  

Science Conference Proceedings (OSTI)

Different types of Phase Change Materials (PCMs) have been tested as dynamic components in buildings during the last 4 decades. Most historical studies have found that PCMs enhance building energy performance. Some PCM-enhanced building materials, like PCM-gypsum boards or PCM-impregnated concretes have already found their limited applications in different countries. Today, continued improvements in building envelope technologies suggest that throughout Southern and Central US climates, residences may soon be routinely constructed with PCM in order to maximize insulation effectiveness and maintain low heating and cooling loads. The proposed paper presents experimental and numerical results from thermal performance studies. These studies focus on blown fiber glass insulation modified with a novel spray-applied microencapsulated PCM. Experimental results are reported for both laboratory-scale and full-size building elements tested in the field. In order to confirm theoretical predictions, PCM enhanced fiber glass insulation was evaluated in a guarded hot box facility to demonstrate heat flow reductions when one side of a test wall is subjected to a temperature increase. The laboratory work showed reductions in heat flow of 30% due to the presence of approximately 20 wt % PCM in the insulation. Field testing of residential attics insulated with blown fiber glass and PCM was completed in Oak Ridge, Tennessee. Experimental work was followed by detailed whole building EnergyPlus simulations in order to generate energy performance data for different US climates. In addition, a series of numerical simulations and field experiments demonstrated a potential for application of a novel PCM fiber glass insulation as enabling technology to be utilized during the attic thermal renovations.

Investigation of Cooling and Dehumidification Energy Use and Indoor Thermal Conditions in Polk County Schools Permanent Replacement Classroom Buildings  

E-Print Network (OSTI)

Increasing enrollment in grades K-12 coupled with the spiraling costs of construction has pushed school boards to develop more cost-effective classrooms, from the perspective of initial cost, longterm energy consumption, and ease of maintenance. To this end, the Florida's Polk County School Board has developed a four-quad permanent replacement classroom building. Each classroom is equipped with a package terminal heat pump (PTHP) with a thermostat control with a four-hour crank timer. The objective of this research was to compare the energy consumption and interior conditions of the autoclaved aerated concrete (AAC) construction with an unvented roof assembly to that of the conventional metal framing and concrete panel buildings. Four buildings, 2 metal-framed and 2 AAC buildings with dehumidifiers were chosen for extensive testing and monitoring. The goal was to maintain a relative humidity of 50% as well as an interior temperature of 75oF.

NREL Evaluates Thermal Performance of Uninsulated Walls to Improve Accuracy of Building Energy Simulation Tools (Fact Sheet)  

SciTech Connect

NREL researchers discover ways to increase accuracy in building energy simulations tools to improve predictions of potential energy savings in homes. Uninsulated walls are typical in older U.S. homes where the wall cavities were not insulated during construction or where the insulating material has settled. Researchers at the National Renewable Energy Laboratory (NREL) are investigating ways to more accurately calculate heat transfer through building enclosures to verify the benefit of energy efficiency upgrades that reduce energy use in older homes. In this study, scientists used computational fluid dynamics (CFD) analysis to calculate the energy loss/gain through building walls and visualize different heat transfer regimes within the uninsulated cavities. The effects of ambient outdoor temperature, the radiative properties of building materials, insulation levels, and the temperature dependence of conduction through framing members were considered. The research showed that the temperature dependence of conduction through framing members dominated the differences between this study and previous results - an effect not accounted for in existing building energy simulation tools. The study provides correlations for the resistance of the uninsulated assemblies that can be implemented into building simulation tools to increase the accuracy of energy use estimates in older homes, which are currently over-predicted.

Compared with flat glass, the PVB laminated glass shields 44 percent of the solar radiation from entering the room and reduces 40 percent of the shading coefficient. At the same time, 28 percent of the cooling load, 21 percent of installed capacity and 8.6 percent of full-load operation time can be saved.

Design and Construction of a Guarded Hot Box Facility for Evaluating the Thermal Performance of Building Wall Materials  

E-Print Network (OSTI)

The focus of this study was to design and build a guarded hot box to test the R-Value of building materials. The Riverside Energy Efficiency Laboratory is looking to expand their testing capabilities by including this service. Eventually, the laboratory will become energy star certified. A guarded hot box facility consists of two boxes maintained at specific temperatures and a guard box around each one that is maintained at the same temperature as the box it surrounds. The ASTM C1363 standard was used as guide for the construction and testing of sample specimen. This standard called for an air velocity profile uniform within 10 percent of the average. Velocity tests were performed with various different configurations to give a uniform velocity. Although the velocity did not meet standards, the configuration chosen included a piece of 1/4" pegboard placed 2" away from the top and the bottom of the inner box. By using the known overall heat added and removed from the system, as well as all the heat losses the heat transferred through the specimen and its R-Value can be calculated. The uncertainty of the R-Value and the accuracy of the testing facility gave conflicting results. Future experiments will use improved testing methods that include differential thermocouples to obtain better uncertainty for the R-Value calculations.

Solar buildings. Overview: The Solar Buildings Program  

DOE Green Energy (OSTI)

Buildings account for more than one third of the energy used in the United States each year, consuming vast amounts of electricity, natural gas, and fuel oil. Given this level of consumption, the buildings sector is rife with opportunity for alternative energy technologies. The US Department of Energy`s Solar Buildings Program was established to take advantage of this opportunity. The Solar Buildings Program is engaged in research, development, and deployment on solar thermal technologies, which use solar energy to produce heat. The Program focuses on technologies that have the potential to produce economically competitive energy for the buildings sector.

Review of the aquifer seasonal thermal energy storage building HVAC system at the Melville, New York, Mid-Island Mail Facility  

DOE Green Energy (OSTI)

The successful widespread commercialization of aquifer thermal energy storage (ATES) in the United States will depend on the effectiveness with which the experiences gained from early full-scale systems are used as guides in the design, installation and operation of future projects. One such early system from which both anecdotal and quantitative information is available is the Mid-Island Postal Facility in Melville, New York. At this facility, built in the mid-1980s, an ATES system has been integrated with the building`s central heating and cooling plant. ``Cold`` wells are charged with water that is cooled during the winter by heat pump and closed circuit cooler operation. Water from these cold wells is then used to meet the facility`s cooling load during the summer, before being pumped back into the ground at ``Warm`` wells. Dehumidification during summer operation is accomplished by a liquid desiccant system that uses propane boilers to provide a heat source for desiccant regeneration. This system will also add water to the air during periods of low humidity. This paper provides an overview of the project, and describes the analysis being performed to assess energy and economic merits of this innovative system.

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.

Energy utilization analysis of buildings  

DOE Green Energy (OSTI)

The accurate calculation of the energy requirements and heating and cooling equipment sizes for buildings is one of the most important, as well as one of the most difficult, problems facing the engineer. The fundamental principles utilized in the procedures developed by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) are explained and brief descriptions of the computer programs using these procedures are given. Such computer programs generally are capable of: simulating the thermal response of a building to all sources of heat gains and losses, accounting for all non-thermal energy requirements in the building or on the sites, translating the building operating schedules into energy demand and consumption, identifying the peak capacity requirements of heating and cooling equipment, and performing an economic analysis that would select the most economical overall owning and operating cost equipment and energy source that minimize the building's life cycle cost.

Mobile Window Thermal Test  

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

Mobile Window Thermal Test (MoWiTT) Facility Mobile Window Thermal Test (MoWiTT) Facility winter.jpg (469135 bytes) The window has come a long way since the days when it was a single pane of glass in a wood frame. Low-emissivity windows were designed to help buildings retain some of the energy that would have leaked out of less efficient windows. Designing efficient window-and-frame systems is one strategy for reducing the energy use of buildings. But the net energy flowing through a window is a combination of temperature- driven thermal flows and transmission of incident solar energy, both of which vary with time. U-factor and solar heat gain coefficient (SHGC), the window properties that control these flows, depend partly on ambient conditions. Window energy flows can affect how much energy a building uses, depending on when the window flows are available to help meet other energy demands within the building, and when they are adverse, adding to building energy use. This leads to a second strategy for reducing building energy use: using the beneficial solar gain available through a window, either for winter heating or for daylighting, while minimizing adverse flows.

Energy efficient buildings: A world of possibilities  

SciTech Connect

Throughout the world, buildings are a major energy consumer. However, it can be shown that buildings that save from 30 to 50% over common practice can be built using available technologies while actually increasing occupant comfort and functionality. In addition, many technologies are in the development stage that promise even further increases in energy efficiency in buildings. This paper reviews the current state-of-the-art in energy efficient building practice including building equipment and envelopes. Topics discussed include heating, ventilating and air conditioning equipment; lighting; insulation; building envelopes; and building commissioning. The energy effects of switching to non-chlorofluorocarbons in building insulation and refrigeration equipment are discussed. Advanced technologies currently under development that might have a substantial impact on future energy use including advanced absorption chillers, new lighting and window technologies, and thermally activated heat pumps are also described. 24 refs., 6 figs.

INL High Performance Building Strategy  

SciTech Connect

High performance buildings, also known as sustainable buildings and green buildings, are resource efficient structures that minimize the impact on the environment by using less energy and water, reduce solid waste and pollutants, and limit the depletion of natural resources while also providing a thermally and visually comfortable working environment that increases productivity for building occupants. As Idaho National Laboratory (INL) becomes the nation’s premier nuclear energy research laboratory, the physical infrastructure will be established to help accomplish this mission. This infrastructure, particularly the buildings, should incorporate high performance sustainable design features in order to be environmentally responsible and reflect an image of progressiveness and innovation to the public and prospective employees. Additionally, INL is a large consumer of energy that contributes to both carbon emissions and resource inefficiency. In the current climate of rising energy prices and political pressure for carbon reduction, this guide will help new construction project teams to design facilities that are sustainable and reduce energy costs, thereby reducing carbon emissions. With these concerns in mind, the recommendations described in the INL High Performance Building Strategy (previously called the INL Green Building Strategy) are intended to form the INL foundation for high performance building standards. This revised strategy incorporates the latest federal and DOE orders (Executive Order [EO] 13514, “Federal Leadership in Environmental, Energy, and Economic Performance” [2009], EO 13423, “Strengthening Federal Environmental, Energy, and Transportation Management” [2007], and DOE Order 430.2B, “Departmental Energy, Renewable Energy, and Transportation Management” [2008]), the latest guidelines, trends, and observations in high performance building construction, and the latest changes to the Leadership in Energy and Environmental Design (LEED®) Green Building Rating System (LEED 2009). The document employs a two-level approach for high performance building at INL. The first level identifies the requirements of the Guiding Principles for Sustainable New Construction and Major Renovations, and the second level recommends which credits should be met when LEED Gold certification is required.

Design for Energy Efficiency in Residential Buildings  

E-Print Network (OSTI)

This paper presents the thermal design and heating design of an energy saving residential building in Beijing where the owners lived until 2004. Results show the advantages and disadvantages of a household-based heating mode by natural gas. Based on the quantity of natural gas by field tests in 2005, we conclude that thermal design influences heating design calculations.

UNDERSTANDING FLOW OF ENERGY IN BUILDINGS USING MODAL ANALYSIS METHODOLOGY  

SciTech Connect

It is widely understood that energy storage is the key to integrating variable generators into the grid. It has been proposed that the thermal mass of buildings could be used as a distributed energy storage solution and several researchers are making headway in this problem. However, the inability to easily determine the magnitude of the building’s effective thermal mass, and how the heating ventilation and air conditioning (HVAC) system exchanges thermal energy with it, is a significant challenge to designing systems which utilize this storage mechanism. In this paper we adapt modal analysis methods used in mechanical structures to identify the primary modes of energy transfer among thermal masses in a building. The paper describes the technique using data from an idealized building model. The approach is successfully applied to actual temperature data from a commercial building in downtown Boise, Idaho.

Commercial Building HVAC: How it Affects People Commercial Building HVAC: How it Affects People Speaker(s): William Fisk Date: November 13, 2000 - 12:00pm Location: Bldg. 90 Seminar Host/Point of Contact: David Faulkner Commercial building heating, ventilating, and air conditioning (HVAC) systems are designed primarily to maintain a reasonable level of thermal comfort while limiting first costs and energy consumption. However, research conducted predominately within the last decade suggests that commercial building HVAC significantly influences human outcomes other than thermal comfort, including the health, satisfaction, and work performance of the building's occupants. This presentation will review the relationships of these outcomes with HVAC system type, filtration system efficiency, indoor air temperature, and outside air ventilation rate.

Thermally activated heat pumps  

SciTech Connect

This article describes research to develop efficient gas-fired heat pumps heat and cool buildings without CFCs. Space heating and cooling use 46% of all energy consumed in US buildings. Air-conditioning is the single leading cause of peak demand for electricity and is a major user of chlorofluorocarbons (CFCs). Advanced energy conversion technology can save 50% of this energy and eliminate CFCs completely. Besides saving energy, advanced systems substantially reduce emissions of carbon dioxide (a greenhouse gas), sulfur dioxide, and nitrogen oxides, which contribute to smog and acid rain. These emissions result from the burning of fossil fuels used to generate electricity. The Office of Building Technologies (OBT) of the US Department of Energy supports private industry`s efforts to improve energy efficiency and increase the use of renewable energy in buildings. To help industry, OBT, through the Oak Ridge National Laboratory, is currently working on thermally activated heat pumps. OBT has selected the following absorption heat pump systems to develop: generator-absorber heat-exchange (GAX) cycle for heating-dominated applications in residential and light commercial buildings; double-condenser-coupled (DCC) cycle for commercial buildings. In addition, OBT is developing computer-aided design software for investigating the absorption cycle.

Buildings Operations and ETS Exposure  

E-Print Network (OSTI)

Mechanical systems are used in buildings to provide conditioned air, dissipate thermal loads, dilute contaminants, and maintain pressure differences. The characteristics of these systems and their operations have implications for the exposures of workers to environmental tobacco smoke (ETS) and for the control of these exposures. This review describes the general features of building ventilation systems and the efficacy of ventilation for controlling contaminant concentrations. Ventilation can reduce the concentration of ETS through dilution, but central heating, ventilating, and air conditioning (HVAC) can also move air throughout a building that has been contaminated by ETS. An understanding of HVAC systems is needed to develop models for exposures of workers to ETS.- Environ Health Perspect 107(Suppl 2):313-317 (1999).

Building America  

Science Conference Proceedings (OSTI)

Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

Thermal Storage with Conventional Cooling Systems  

E-Print Network (OSTI)

The newly opened Pennsylvania Convention Center in Philadelphia, PA; Exxon's Computer Facility at Florham Park, NJ; The Center Square Building in Philadelphia, are success stories for demand shifting through thermal storage. These buildings employ a simple thermal energy storage system that already exists in almost every structure - concrete. Thermal storage calculations simulate sub-cooling of a building's structure during unoccupied times. During occupied times, the sub-cooled concrete reduces peak cooling demand, thereby lowering demand and saving money. In addition, significant savings are possible in the first cost of chilled water equipment, and the smaller chillers run at peak capacity and efficiency during a greater portion of their run time. The building, controlled by an Energy Management and Control System (EMCS), "learns" from past experience how to run the building efficiently. The result is an optimized balance between energy cost and comfort.

Passive solar concepts for multistory buildings  

DOE Green Energy (OSTI)

Multistory buildings long in the east-west direction and short in the north-south direction offer good opportunity for passive solar application. If each unit within the building is designed so that the Solar Savings Fraction is the same, each will respond to the weather the same way and no unit-to-unit heat distribution is needed. A numerical example for Denver is given indicating excellent thermal performance and a several-day thermal response time. Solutions involving distribution of heat from unit to unit are also discussed as well as top-floor and south-wall variations.

Sustainable Energy Future in China's Building Sector  

E-Print Network (OSTI)

This article investigates the potentials of energy-saving and mitigation of green-house gas (GHG) emission offered by implementation of building energy efficiency policies in China. An overview of existing literature regarding long-term energy demand and CO2 emission forecast scenarios is presented, it is found that the building sector will account for about one third of energy demand in China by 2020 and would have significant environmental implications in terms of GHG and other pollutant gases emission. Energy consumption in buildings could be reduced by 100-300 million tons of oil equivalent (mtoe) in 2030 compared to the business-as-usual (BAU) scenario, which means that 600-700 million metric tons of carbon dioxide (CO2) emissions could be saved by implementing appropriate energy policies within an adapted institutional framework. The main energy saving potentials in buildings can be achieved by improving building's thermal performance and district heating system.

Scenario Analysis of Peak Demand Savings for Commercial Buildings with Scenario Analysis of Peak Demand Savings for Commercial Buildings with Thermal Mass in California Title Scenario Analysis of Peak Demand Savings for Commercial Buildings with Thermal Mass in California Publication Type Conference Paper LBNL Report Number LBNL-3636e Year of Publication 2010 Authors Yin, Rongxin, Sila Kiliccote, Mary Ann Piette, and Kristen Parrish Conference Name 2010 ACEEE Summer Study on Energy Efficiency in Buildings Conference Location Pacific Grove, CA Keywords demand response and distributed energy resources center, demand response research center, demand shifting (pre-cooling), DRQAT Abstract This paper reports on the potential impact of demand response (DR) strategies in commercial buildings in California based on the Demand Response Quick Assessment Tool (DRQAT), which uses EnergyPlus simulation prototypes for office and retail buildings. The study describes the potential impact of building size, thermal mass, climate, and DR strategies on demand savings in commercial buildings. Sensitivity analyses are performed to evaluate how these factors influence the demand shift and shed during the peak period. The whole-building peak demand of a commercial building with high thermal mass in a hot climate zone can be reduced by 30% using an optimized demand response strategy. Results are summarized for various simulation scenarios designed to help owners and managers understand the potential savings for demand response deployment. Simulated demand savings under various scenarios were compared to field-measured data in numerous climate zones, allowing calibration of the prototype models. The simulation results are compared to the peak demand data from the Commercial End-Use Survey for commercial buildings in California. On the economic side, a set of electricity rates are used to evaluate the impact of the DR strategies on economic savings for different thermal mass and climate conditions. Our comparison of recent simulation to field test results provides an understanding of the DR potential in commercial buildings.

What do hourly performance data on a building tell us  

DOE Green Energy (OSTI)

Hourly performance data on a building contain valuable information on the dynamics of the building and of the HVAC systems. Quantities such as the building loss coefficient, solar gains, and the net effect of thermal masses and their couplings are all contained in the data. The building element vector analysis (BEVA) method has been applied to a multizone residential passive solar building monitored under the SERI Class B program. Using short-term data (approximately one week), the building parameters were regressed. With these as inputs, the subsequent performance of the building was well predicted. Using performance data for the period February 3-9, 1982, the building vectors were obtained by regression. The resulting best fit for the zone temperature is given. These parameters were used to predict the temperature for the period February 10-14. The resulting values are also plotted along with the outdoor temperature, solar radiation on a south vertical surface, and auxiliary energy for these periods.

Experimental Method to Determine the Energy Envelope Performance of Buildings  

E-Print Network (OSTI)

In France, buildings represent 40% of the annual energy consumption. This sector represents an important stack to achieve the objective of reducing by 4 the greenhouse gas emissions by 2050. Knowledge of construction techniques and the use of equipments are the main keys to realize low energy buildings. To achieve this aim, we monitored 24 experimental buildings. In order to evaluate these experimental buildings we compare the monitored energy performance to the predicted energy performance and explain the differences between both performances. Therefore, we developed an in-situ method to determine the thermal envelope performance of buildings (Ubuilding). The buildings are monitored in order to know the followings inputs: Occupancy rate; Heat supply; Solar supply; Ventilation and airflow losses; Distributions losses. The aim of this paper is to present the developed method and monitoring protocol. In order to validate the proposed experimental approach, we will present applications on different monitoring buildings in context of the project PREBAT (Research Program on Building's Evaluation).

Thermal Batteries for Electric Vehicles  

Science Conference Proceedings (OSTI)

HEATS Project: UT Austin will demonstrate a high-energy density and low-cost thermal storage system that will provide efficient cabin heating and cooling for EVs. Compared to existing HVAC systems powered by electric batteries in EVs, the innovative hot-and-cold thermal batteries-based technology is expected to decrease the manufacturing cost and increase the driving range of next-generation EVs. These thermal batteries can be charged with off-peak electric power together with the electric batteries. Based on innovations in composite materials offering twice the energy density of ice and 10 times the thermal conductivity of water, these thermal batteries are expected to achieve a comparable energy density at 25% of the cost of electric batteries. Moreover, because UT Austin’s thermal energy storage systems are modular, they may be incorporated into the heating and cooling systems in buildings, providing further energy efficiencies and positively impacting the emissions of current building heating/cooling systems.

Monitoring and Optimization of Building Operations of a Low-Energy School Building  

E-Print Network (OSTI)

The ambitious design and energy concept of the new Gebhard-Müller-Schule (GMS) school building in Biberach/Riss, Germany proved itself during the first three school years of operation. The intended target value of 30 kWh/(m2a) overall heating energy consumption was almost met during the second year of operation in 2006 and finally achieved in 2007, due to well-working optimization measures, which were identified through monitoring of the building operation. Heating and cooling energy is mainly provided by a groundwater well plant, which serves as a heat source for two heat pumps as well as a direct cooling source for supplying the radiant heating and cooling system that is integrated in the concrete floor and ceiling slabs (thermally activated building component systems – TABS). Indoor air conditioning and server room cooling are also connected to the groundwater cooling system. The main component of the groundwater well plant is a submersible pump on the bottom of the well which is located underneath the building. The pump supplies the building reliably with geothermal energy, but also consumes a significant amount of electricity. Monitoring and optimization of the building’s operation, funded by the Federal Ministry of Economics and Technology in Germany, revealed fundamental findings about the operation of the system and the possibilities to improve the building’s performance. Since 2005, the measurements show a continuous increase in efficiency, particularly in the field of auxiliary energies. This significantly increased performance clearly shows the potential of the use of groundwater for heating and cooling purposes and of thermally activated building component systems. In addition the measurements reveal the sensitivity of the system efficiency in terms of operating parameters.

NREL: News Feature - Building Panels Protect, Provide Comfort  

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

Building Panels Protect, Provide Comfort Building Panels Protect, Provide Comfort October 30, 2009 Walking into a building constructed before the days of heating systems and air conditioning, such as a southwestern adobe, still elicits a sense of comfort and coziness. The concept of using thermal mass in walls to help maintain the temperature of a building is not new. And now, this tried and true method is being used to regulate comfort systems of NREL's Research Support Facilities (RSF), one of the most energy efficient buildings in the world. "In this case, the exterior skin of the building is doing more than just keeping the weather out," Philip Macey, project manager for RNL, the design firm for the RSF, said. "Precast panels installed as the walls are actually part of the heating and cooling system for the building.

DEVELOPMENT AND EVALUATION OF FLEXIBLE, MULTIZONE MULTIFAMILY BUILDING SIMULATION MODEL  

SciTech Connect

Since 2011, Oak Ridge National Laboratory (ORNL) has been developing a multifamily building energy audit tool sponsored by U.S. Department of Energy (DOE) Weatherization program. Although weatherization of multifamily buildings is gaining increased attention in the U.S, available energy audit tools for multifamily buildings were found to need desirable improvements. On the wish list of field experts was the basic ability to model multizone buildings (i.e., one thermal zone per dwelling unit) with simplified user inputs, which allows a better analysis of decentralized and centralized HVAC and domestic hot water systems of multifamily buildings without having to create detailed building models. This paper describes detailed procedure of evaluation of the tool to perform an energy analysis in an existing multifamily building.
