A Framework for Comparative Assessments of Energy Efficiency Policy Measures  

SciTech Connect

When policy makers propose new policies, there is a need to assess the costs and benefits of the proposed policy measures, to compare them to existing and alternative policies, and to rank them according to their effectiveness. In the case of equipment energy efficiency regulations, comparing the effects of a range of alternative policy measures requires evaluating their effects on consumers’ budgets, on national energy consumption and economics, and on the environment. Such an approach should be able to represent in a single framework the particularities of each policy measure and provide comparable results. This report presents an integrated methodological framework to assess prospectively the energy, economic, and environmental impacts of energy efficiency policy measures. The framework builds on the premise that the comparative assessment of energy efficiency policy measures should (a) rely on a common set of primary data and parameters, (b) follow a single functional approach to estimate the energy, economic, and emissions savings resulting from each assessed measure, and (c) present results through a set of comparable indicators. This framework elaborates on models that the U.S. Department of Energy (DOE) has used in support of its rulemakings on mandatory energy efficiency standards. In addition to a rigorous analysis of the impacts of mandatory standards, DOE compares the projected results of alternative policy measures to those projected to be achieved by the standards. The framework extends such an approach to provide a broad, generic methodology, with no geographic or sectoral limitations, that is useful for evaluating any type of equipment energy efficiency market intervention. The report concludes with a demonstration of how to use the framework to compare the impacts estimated for twelve policy measures focusing on increasing the energy efficiency of gas furnaces in the United States.

Measuring industrial energy efficiency: Physical volume versus economic value  

SciTech Connect

This report examines several different measures of industrial output for use in constructing estimates of industrial energy efficiency and discusses some reasons for differences between the measures. Estimates of volume-based measures of output, as well as 3 value-based measures of output (value of production, value of shipments, and value added), are evaluated for 15 separate 4-digit industries. Volatility, simple growth rate, and trend growth rate estimates are made for each industry and each measure of output. Correlations are made between the volume- and value-based measures of output. Historical energy use data are collected for 5 of the industries for making energy- intensity estimates. Growth rates in energy use, energy intensity, and correlations between volume- and value-based measures of energy intensity are computed. There is large variability in growth trend estimates both long term and from year to year. While there is a high correlation between volume- and value-based measures of output for a few industries, typically the correlation is low, and this is exacerbated for estimates of energy intensity. Analysis revealed reasons for these low correlations. It appears that substantial work must be done before reliable measures of trends in the energy efficiency of industry can be accurately characterized.

Lessons learned on closed cavity thermophotovoltaic system efficiency measurements  

DOE Green Energy (OSTI)

Previous efficiency measurements have highlighted that to accurately measure and predict thermophotovoltaic (TPV) integrated cell or array efficiencies, a thorough understanding of the system is required. This includes knowledge of intrinsic diode and filter characteristics, radiative surface properties of all materials used within the cavity, and an intimate knowledge of the radiator/photon source. As a result of these and other lessons learned, the cavity test fixture used in earlier experiments was redesigned. To reduce radiator temperature gradients, the radiator was oversized and thickened, cavity walls were eliminated, the diode heat sink and shielding material were separated, and the cold side was redesigned to incorporate a steady state heat absorbed measurement technique. This redesigned test fixture provides an isothermal radiator and significantly enhances calorimetry capabilities. This newly designed cavity test fixture, in conjunction with the Monte Carlo Photon Transport code RACER-X, was used to improve and demonstrate the understanding of in-cavity TPV diode/module system efficiency testing. A single TPV diode was tested in this new fixture and yielded good agreement between measurements and predictions.

Indoor air quality measurements in energy efficient buildings  

DOE Green Energy (OSTI)

The Energy Efficient Buildings Program of the Lawrence Berkeley Laboratory (LBL) has designed and fabricated a mobile laboratory for research and development studies of ventilation requirements and energy utilization in residential and commercial buildings. The Energy Efficient Buildings (EEB) Mobile Laboratory is used in studies of indoor air quality in buildings before and after energy conservation retrofits and in new buildings incorporating energy efficient designs. Indoor air quality measurements have been conducted in residential buildings and work in progress includes indoor air quality monitoring in schools, hospitals, and energy efficient residential buildings. The monitoring program includes measurement of CO, CO/sub 2/, SO/sub 2/, NO, NO/sub 2/, O/sub 3/, infiltration rate (tracer gas technique), and aerosol size distribution on a continuous basis. Total and respirable-fraction particulate samples are collected on membrane filter media for analysis by x-ray fluorescence (XRFA), photoelectron spectroscopy (ESCA), proton activation analysis (PAA), combustion, and wet-chemistry techniques for the determination of particulate elemental composition (S, N, C, etc.) and ionic species such as SO/sub 4//sup 2 -/, NO/sub 3//sup -/, and NH/sub 4//sup +/. Results of the initial phases of this program indicate that the concentrations of some gaseous and respirable particulate air pollutants in specific indoor environments exceed those levels commonly found in the outdoor urban air environment.

TPV efficiency measurements and predictions for a closed cavity geometry  

DOE Green Energy (OSTI)

A thermophotovoltaic (TPV) efficiency measurement, within a closed cavity, is an integrated test which incorporates four fundamental parameters of TPV direct energy conversion. These are: (1) the TPV devices, (2) spectral control, (3) a radiation/photon source, and (4) closed cavity geometry effects. The overall efficiency of the TPV device is controlled by the TP cell performance, the spectral control characteristics, the radiator temperature and the geometric arrangement. Controlled efficiency measurements and predictions provide valuable feedback on all four. This paper describes and compares two computer codes developed to model 16, 1 cm{sup 2} TPV cells (in a 4 x 4 configuration) in a cavity geometry. The first code, subdivides the infrared spectrum into several bands and then numerically integrates over the spectrum to provide absorbed heat flux and cell electrical output performance predictions (assuming infinite parallel plates). The second code, utilizes a Monte Carlo Photon Transport code that tracks photons, from birth at the radiation source, until they either escape or are absorbed. Absorption depends upon energy dependent reflection probabilities assigned to every geometrical surface within the cavity. The model also has the capability of tallying above and below bandgap absorptions (as a function of location) and can support various radiator temperature profiles. The arrays were fabricated using 0.55 eV InGaAs cells with Si/SiO interference filters for spectral control and at steady state conditions, array efficiency was calculated as the ratio of the load matched power to its absorbed heat flux. Preliminary experimental results are also compared with predictions.

Cross-Sector Impact Analysis of Industrial Efficiency Measures  

SciTech Connect

The industrial or manufacturing sector is a foundational component to all economic activity. In addition to being a large direct consumer of energy, the manufacturing sector also produces materials, products, and technologies that influence the energy use of other economic sectors. For example, the manufacturing of a lighter-weight vehicle component affects the energy required to ship that component as well as the fuel efficiency of the assembled vehicle. Many energy efficiency opportunities exist to improve manufacturing energy consumption, however comparisons of manufacturing sector energy efficiency investment opportunities tend to exclude any impacts that occur once the product leaves the factory. Expanding the scope of analysis to include energy impacts across different stages of product life-cycle can highlight less obvious opportunities and inform actions that create the greatest economy-wide benefits. We present a methodology and associated analysis tool (LIGHTEnUP Lifecycle Industry GHgas, Technology and Energy through the Use Phase) that aims to capture both the manufacturing sector energy consumption and product life-cycle energy consumption implications of manufacturing innovation measures. The tool architecture incorporates U.S. national energy use data associated with manufacturing, building operations, and transportation. Inputs for technology assessment, both direct energy saving to the manufacturing sector, and indirect energy impacts to additional sectors are estimated through extensive literature review and engineering methods. The result is a transparent and uniform system of comparing manufacturing and use-phase impacts of technologies.

Dephasing and Measurement Efficiency via a Quantum Dot Detector  

E-Print Network (OSTI)

We study charge detection and controlled dephasing of a mesoscopic system via a quantum dot detector (QDD), where the mesoscopic system and the QDD are capacitively coupled. The QDD is considered to have coherent resonant tunnelling via a single level. It is found that the dephasing rate is proportional to the square of the conductance of the QDD for the Breit-Wigner model, showing that the dephasing is completely different from the shot noise of the detector. The measurement rate, on the other hand, shows a dip near the resonance. Our findings are peculiar especially for a symmetric detector in the following aspect: The dephasing rate is maximum at resonance of the QDD where the detector conductance is insensitive to the charge state of the mesoscopic system. As a result, the efficiency of the detector shows a dip and vanishes at resonance, in contrast to the single-channel symmetric non-resonant detector that has always a maximum efficiency. We find that this difference originates from a very general property of the scattering matrix: The abrupt phase change exists in the scattering amplitudes in the presence of the symmetry, which is insensitive to the detector current but {\\em stores} the information of the quantum state of the mesoscopic system.

Evaluation of Energy Efficiency Measures in Hot and Humid Climates  

E-Print Network (OSTI)

Hot and humid climates present some of the most complex challenges for sustainable building designs. High temperatures coupled with high humidity create extreme comfort problems and exacerbate the potential for condensation, mold and mildew. These are usually remedied with conventional mechanical air conditioning systems, but the move toward sustainability urges designers to find less energy intensive solutions. An integrated design process coupled with energy modeling and lifecycle analysis can unite design teams around desired outcomes to provide an optimized design solution for projects in these climates. Such an approach involves first minimizing building loads and then reducing residual energy consumed by the HVAC systems. This paper presents an integrated design approach to evaluating the most efficient energy measures in hot and humid climates and summarizes the findings of a series of cases using this approach, including international examples of office, education, and small retail buildings in ASHRAE Climate Zones 1A and 2A.

Characterization of Si nanostructures using internal quantum efficiency measurements  

DOE Green Energy (OSTI)

Hemispherical reflectance and internal quantum efficiency measurements have been employed to evaluate the response of Si nanostructured surfaces formed by using random and periodic reactive ion etching techniques. Random RIE-textured surfaces have demonstrated solar weighted reflectance of {approx} 3% over 300--1,200-nm spectral range even without the benefit of anti-reflection films. Random RIE-texturing has been found to be applicable over large areas ({approximately} 180 cm{sup 2}) of both single and multicrystalline Si surfaces. Due to the surface contamination and plasma-induced damage, RIE-textured surfaces did not initially provide increased short circuit current as expected from the enhanced absorption. Improved processing combined with wet-chemical damage removal etches resulted in significant improvement in the short circuit current with IQEs comparable to the random, wet-chemically textured surfaces. An interesting feature of the RIE-textured surfaces was their superior performance in the near IR spectral range. The response of RIE-textured periodic surfaces can be broadly classified into three distinct regimes. One-dimensional grating structures with triangular profiles are characterized by exceptionally low, polarization-independent reflective behavior. The reflectance response of such surfaces is similar to a graded-index anti-reflection film. The IQE response from these surfaces is severely degraded in the UV-Visible spectral region due to plasma-induced surface damage. One-dimensional grating structures with rectangular profiles exhibit spectrally selective absorptive behavior with somewhat similar IQE response. The third type of grating structure combines broadband anti-reflection behavior with significant IQE enhancement in 800--1,200-nm spectral region. The hemispherical reflectance of these 2D grating structures is comparable to random RIE-textured surfaces. The IQE enhancement in the long wavelength spectral region can be attributed to increased coupling into obliquely propagating transmitted diffracted orders inside the Si substrate. Random RIE texturing techniques are expected to find widespread commercial applicability in low-cost, large-area multicrystalline Si solar cells. Grating-texturing techniques are expected to find applications in thin-film and space solar cells.

Generation of a Parabolic Trough Collector Efficiency Curve from Separate Measurements of Outdoor Optical Efficiency and Indoor Receiver Heat Loss  

SciTech Connect

The thermal efficiency of a parabolic trough collector is a function of both the fraction of direct normal radiation absorbed by the receiver (the optical efficiency) and the heat lost to the environment when the receiver is at operating temperature. The thermal efficiency can be determined by testing the collector under actual operating conditions or by separately measuring these two components. This paper describes how outdoor measurement of the optical efficiency is combined with laboratory measurements of receiver heat loss to obtain the thermal efficiency curve. This paper describes this approach and also makes the case that there are advantages to plotting collector efficiency versus the difference between the operating temperature and the ambient temperature at which the receiver heat loss was measured divided by radiation to a fractional power (on the order of 1/3 but obtained via data regression) - as opposed to the difference between operating and ambient temperatures divided by the radiation. The results are shown to be robust over wide ranges of ambient temperature, sky temperature, and wind speed.

Measuring Energy Efficiency Improvements in Industrial Battery Chargers  

E-Print Network (OSTI)

Industrial battery chargers have provided the energy requirements for motive power in industrial facilities for decades. Their reliable and durable performance, combined with their low energy consumption relative to other industrial processes, has left the core charger technology unchanged since its introduction to the market. Recent improvements in charger technology have led to a new generation of high frequency chargers on the market that can provide energy efficiency improvements over existing Silicon Controlled Rectifier (SCR) and Ferroresonant charger technologies. We estimate there are approximately 32,000 three phase chargers in use within Pacific Gas & Electric Company’s service area, using roughly 750 to 1,000 GWh per year. A 10 percent efficiency improvement on every charger would save about 75 to 100 GWh per year. There are three areas of energy losses in the battery and charger system: • Power Conversion Efficiency (energy out of charger vs. energy into charger) • Charge Return (energy out of battery vs. energy into battery): some amount of overcharge is necessary for battery health, but chargers vary in the degree which they overcharge • Standby losses when no battery is connected. PG&E and Southern California Edison (SCE) are testing industrial battery chargers according to a California Energy Commission (CEC) approved test procedure. This test procedure, developed with charger manufacturer input as part of the CEC’s Codes and Standards process, specifies test conditions during active charge, maintenance charge and standby modes. The results from this testing are expected to provide independent confirmation of vendor claims of energy efficiency improvements during all modes of charger operation, and will form the foundation of data for utility energy efficiency programs. Initial test results of one battery charger from each technology type show the Hybrid and High Frequency technology as the top performers when compared to the SCR and Ferroresonant chargers. Multiple chargers from each technology group will be tested in the first half of 2009 to determine an average performance for each technology type. The full set of results will be available in summer 2009.

Measurement of carbon capture efficiency and stored carbon leakage  

DOE Patents (OSTI)

Data representative of a measured carbon dioxide (CO.sub.2) concentration and of a measured oxygen (O.sub.2) concentration at a measurement location can be used to determine whether the measured carbon dioxide concentration at the measurement location is elevated relative to a baseline carbon dioxide concentration due to escape of carbon dioxide from a source associated with a carbon capture and storage process. Optionally, the data can be used to quantify a carbon dioxide concentration increase at the first location that is attributable to escape of carbon dioxide from the source and to calculate a rate of escape of carbon dioxide from the source by executing a model of gas-phase transport using at least the first carbon dioxide concentration increase. Related systems, methods, and articles of manufacture are also described.

Measured Performance of Energy-Efficient Computer Systems  

E-Print Network (OSTI)

The intent of this study is to explore the potential performance of both Energy Star computers/printers and add-on control devices individually, and their expected savings if collectively applied in a typical office building in a hot and humid climate. Recent surveys have shown that the use of personal computer systems in commercial office buildings is expanding rapidly. The energy consumption of such a growing end-use also has a significant impact on the total building power demand. In warmer climates, office equipment energy use has important implications for building cooling loads as well as those directly associated with computing tasks. Recently, the Environmental Protection Agency (EPA) has developed an Energy Star (ES) rating system intended to endorse more efficient equipment. To research the comparative performance of conventional and low-energy computer systems, four Energy Star computer systems and two computer systems equipped with energy saving devices were monitored for power demand. Comparative data on the test results are summarized. In addition, a brief analysis uses the DOE-2.1E computer simulation to examine the impact of the test results and HVAC interactions if generically applied to computer systems in a modern office building in Florida's climate.

Apparatus and method for measuring single cell and sub-cellular photosynthetic efficiency  

DOE Patents (OSTI)

Devices for measuring single cell changes in photosynthetic efficiency in algal aquaculture are disclosed that include a combination of modulated LED trans-illumination of different intensities with synchronized through objective laser illumination and confocal detection. Synchronization and intensity modulation of a dual illumination scheme were provided using a custom microcontroller for a laser beam block and constant current LED driver. Therefore, single whole cell photosynthetic efficiency, and subcellular (diffraction limited) photosynthetic efficiency measurement modes are permitted. Wide field rapid light scanning actinic illumination is provided for both by an intensity modulated 470 nm LED. For the whole cell photosynthetic efficiency measurement, the same LED provides saturating pulses for generating photosynthetic induction curves. For the subcellular photosynthetic efficiency measurement, a switched through objective 488 nm laser provides saturating pulses for generating photosynthetic induction curves. A second near IR LED is employed to generate dark adapted states in the system under study.

Omnium-G parabolic dish optical efficiency: a comparison of two independent measurement techniques  

DOE Green Energy (OSTI)

Measurements made at SERI of the optical efficiency of the Omnium-G parabolic dish concentrator are described. Two independent techniques were used: the cold-water calorimeter method and the heat of fusion method. Results from both techniques agree quite well and indicate that the optical efficiency for a 10-cm receiver aperture is 25%. Optical efficiency measured in early 1979 was 37%, and in mid 1979 it had degraded to 21%. An optical alignment procedure is described that resulted in the increase in optical efficiency from 21% to the current value of 25%.

Generation of a Parabolic Trough Collector Efficiency Curve from Separate Measurements of Outdoor Optical Efficiency and Indoor Receiver Heat Loss: Preprint

The overall efficiency of a parabolic trough collector is a function of both the fraction of direct normal radiation absorbed by the receiver (the optical efficiency) and the heat lost to the environment when the receiver is at operating temperature. The overall efficiency can be determined by testing the collector under actual operating conditions or by separately measuring these two components. This paper describes how outdoor measurement of the optical efficiency is combined with laboratory measurements of receiver heat loss to obtain an overall efficiency curve. Further, it presents a new way to plot efficiency that is more robust over a range of receiver operating temperatures.

In situ changes in the cathode's quantum efficiency and dark current with time were seen during operation of the photo-injector. These changes were correlated with the magnetostatic field at the cathode. In addition, multipacting has been observed under certain conditions. Recent measurements indicate a correlation between multipacting and anomalous photo- and field emission behavior.

Lateral Spectrum Splitting Concentrator Photovoltaics: Direct Measurement of Component and Submodule Efficiency  

Science Conference Proceedings (OSTI)

To achieve high energy conversion efficiency, a solar module architecture called lateral spectrum splitting concentrator photovoltaics (LSSCPV) is being developed. LSSCPV can concentrate available sunlight and laterally split a single beam into bands with different spectra for absorption by different solar cells with band gaps matched to the split spectrum. Test assemblies of a sample LSSCPV architecture were constructed, each of which contains four p-n junctions and two optical pieces. Independent experiments or simulations had been implemented on the components but by using optimal assumptions. In order to examine the actual performances of all the components, which are dependent on each other and the light source, direct outdoor measurements were made. A set of self-consistent efficiency definitions was articulated and a test bed was developed to measure the parameters required by the efficiency calculation. By comparing the component efficiency items derived from the outdoor measurement and the expected values based on independent simulations, the potential opportunities for efficiency improvement are determined. In the outdoor measurement at the University of Delaware, the optical component demonstrated 89.1% efficiency. Additional assemblies were tested at the National Renewable Energy Laboratory. One assembly demonstrated 36.7% submodule efficiency, which compares favorably with the 32.6% previously reported verified submodule efficiency.

Field Measurements of Heating Efficiency of Electric Forced-Air Furnaces in Six Manufactured Homes.  

Science Conference Proceedings (OSTI)

This report presents the results of field measurements of heating efficiency for six manufactured homes in the Pacific Northwest heated with electric forced-air systems. This is the first in a series of regional and national efforts to measure in detail the heating efficiency of manufactured homes. Only six homes were included in this study because of budgetary constraints; therefore this is not a representative sample. These investigations do provide some useful information on the heating efficiency of these homes. Useful comparisons can be drawn between these study homes and site-built heating efficiencies measured with a similar protocol. The protocol used to test these homes is very similar to another Ecotope protocol used in the study conducted in 1992 and 1993 for the Bonneville Power Administration to test the heating efficiency of 24 homes. This protocol combined real-time power measurements of furnace energy usage with energy usage during co-heat periods. Accessory data such as house and duct tightness measurements and tracer gas measurements were used to describe these homes and their heating system efficiency. Ensuring that manufactured housing is constructed in an energy and resource efficient manner is of increasing concern to manufactured home builders and consumers. No comparable work has been done to measure the heating system efficiency of MCS manufactured homes, although some co-heat tests have been performed on manufactured homes heated with natural gas to validate HUD thermal standards. It is expected that later in 1994 more research of this kind will be conducted, and perhaps a less costly and less time-consuming method for testing efficiencies will be develops.

The results are compared with the ratio energy to real gross domestic product, which typically is pre- sented as a measure of energy intensity. Introduction Energy efficiency and conservation are currently impor- tant components of the debate about the direction of future energy policy. Measuring the actual energy effi- ciency of the U.S. economy is a daunting task because of the immense data requirements for a proper calculation. Appropriate data are difficult to obtain, and as a result historical descriptions of the economy usually are sum- marized in two energy intensity measures: (1) energy

Measuring the energy efficiency of households: an application of frontier production function analysis  

SciTech Connect

A new method to estimate the energy efficiency of households is presented. Households are viewed as productive units organized to provide the occupants with numerous services requiring fuel as an input: house heating to achieve a desired interior temperature, lighting for recreation, etc. The focus is on the efficiency of energy use, not the demand for energy. The approach to measuring efficiency compares a group of productive units along several dimensions of input resources and service outputs. The comparison identifies a subset of units that are considered efficient because they require the least resources per unit of service provided. The efficient units form a production possibility frontier of best practice in service provision. A regression of the two sets of efficiency scores on other variables reflecting locational, dwelling unit, and occupational characteristics is performed to identify factors accounting for differences in efficiency. The results indicate that the more efficient units used electric heat, had higher ratios of non-electric to electric fuel inputs, were owner-occupied, and were built after 1974. The findings also suggest that both family life cycle and income effects account for efficiency differences.

From optimal measurement to efficient quantum algorithms for the hidden subgroup problem over semidirect product groups  

E-Print Network (OSTI)

We approach the hidden subgroup problem by performing the so-called pretty good measurement on hidden subgroup states. For various groups that can be expressed as the semidirect product of an abelian group and a cyclic group, we show that the pretty good measurement is optimal and that its probability of success and unitary implementation are closely related to an average-case algebraic problem. By solving this problem, we find efficient quantum algorithms for a number of nonabelian hidden subgroup problems, including some for which no efficient algorithm was previously known: certain metacyclic groups as well as all groups of the form (Z_p)^r X| Z_p for fixed r (including the Heisenberg group, r=2). In particular, our results show that entangled measurements across multiple copies of hidden subgroup states can be useful for efficiently solving the nonabelian HSP.

Opportunities and Barriers in the Implementation of Energy Efficiency Measures in Plastic Manufacturing  

E-Print Network (OSTI)

The plastic industry in the U.S. employs approximately 9% [1] of the manufacturing work force and consumes approximately 6% [1] of the total energy used by the U.S. industries. According to the Department of Energy (DOE), manufacturers of plastic and other resins are consuming nearly 1,070 trillion Btu [1] of energy in their operations every year, valued at $6.0[1] billion. As escalating energy prices continue to be a concern for industry, many plastic manufacturers are striving to reduce their energy consumption to stay competitive. An alternative to reduced energy consumption is to put in place an energy efficiency strategy. However, while most plastic manufactures are aware of the energy efficiency opportunities in their facilities, the implementation of these opportunities face certain market barriers. These barriers are identified as customers lack the information about energy efficiency technologies, and have limited capital funding to implement the energy efficiency measures. Additionally, it is hard to identify the energy savings opportunities and difficult to quantify their impacts. The purpose of this paper is to discuss the various energy efficiency opportunities in plastic manufacturing and address the market barriers in implementing them. We will identify the energy savings opportunities in plastic manufacturing that can be introduced to reduce energy consumption and decrease production costs, thus giving the customers more competitive edge in both the regional and global markets. We will also discuss various popular energy efficiency measures, the energy savings associated with each measure and their projected simple payback. In terms of policy implication, this paper will discuss various strategies of mitigating potential market barriers in implementing energy efficiency measures on plastic manufacturing industries.

CHP Supported with Energy Efficiency Measures -- A Winning and Environmentally Sound Solution in Finland  

E-Print Network (OSTI)

"In the European Union Energy Programmes, one of the most significant measures in reducing carbon dioxides and other emissions is to build additional CHP technology. This will be implemented with measures to raise the energy efficiency. CHP technology is exceptionally widely used in Finland. At industrial sites, it accounts for more than in any other country in Europe. Owing to limited possibilities to build additional CHP, the focus in Finland is already shifting to other measures that add to energy efficiency. The energy intensive forest industry accounts for about 60% of the industrial energy use in Finland. The CHP plants form the basis for the industry's energy system. The agreement closed between industry and the Government obliges the forest companies to have energy analyses prepared The Government also supports projects that have increased energy efficiency as target. The industry has agreed amongst themselves during 1998 on the game rules that govern the enhancing of the energy efficiency at their pulp and paper mills. Through its solid mastering of the entire energy chain, Fortum -one of the leading Nordic energy companies, is focusing on the development of products and processes with strong environmental characteristics. Apart from actively implementing CHP projects around the Baltic region, the company is also strongly supporting the forest industry companies in their attempts to develop techniques aiming at enhancing energy efficiency at their mill units. The computer modeling know-how that over ten past years has been developed in the power plant environment provides the foundation for Fortum's energy analyses. This combined with customers know-how of energy and processes, creates an exceptionally efficient operation to enhance energy efficiency of pulp and paper mill units. "

Analysis of Energy Efficiency Measures in Rehabilitation of Multifamily Housing Units  

E-Print Network (OSTI)

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

Applying the modified quadriform to measure efficiency in Texas public schools  

E-Print Network (OSTI)

The purpose of this study was to identify school districts in the state of Texas that would be considered efficient based on the modified quadriform model, and to identify alterable school characteristics most associated with those efficient schools. The researcher used data from the 2003-2004 Texas Academic Excellence Indicator System in this analysis. Texas school districts that had low expenditures with high student output were classified as efficient. There were two stages to the modified quadriform analysis. In stage one the relationship between input and output was evaluated by two separate linear regressions. The input regression modeled total per pupil expenditure for the district regressed against unalterable school characteristics such as total district enrollment, percentage of economically disadvantaged students, percentage of special education students, percentage of minority students, and local tax base value per pupil. In the output regression six different measures of student outcomes were regressed against the same unalterable characteristics. The measures of student achievement used were the percentage of all students passing the math and reading Texas Assessments of Knowledge and Skills, graduation completion rate, percentage of students taking the Scholastic Aptitude Test and the ACT Test, and the mean scores on the Scholastic Aptitude Test and/or ACT Test. Once the efficient school districts were identified using the positive and negative residuals from the regressions, a discriminant analysis was conducted to determine what alterable characteristics had the most significant relationship with the different student outcome measures. Just over 32% of Texas School Districts would be considered efficient in this model, and the number of students per teacher has a significant relationship with the output measures of mean SAT and ACT scores, district completion rate, and Texas Assessment of Knowledge and Skills scores in both math and reading. The data also showed that the percentage of expenditures at central administration was least associated with mean Scholastic Aptitude Test and ACT scores along with district completion rate. This study was intended to be a descriptive �bird�s eye� view of efficiency in the Texas system, the researcher believes that this initial study will be a catalyst for more focused research using this production function method of measuring efficiency, and that one day it may lead to an operational definition of efficiency in the Texas system.

Predicted versus monitored performance of energy-efficiency measures in new commercial buildings from energy edge  

SciTech Connect

Energy Edge is a research-oriented demonstration program involving 28 new commercial buildings in the Pacific Northwest. This paper discusses the energy savings and cost-effectiveness of energy-efficiency measures for the first 12 buildings evaluated using simulation models calibrated with measured end-use data. Average energy savings per building from the simulated code baseline building was 19%, less than the 30% target. The most important factor for the lower savings is that many of the installed measures differ from the measures specified in the design predictions. Only one of the first 12 buildings met the project objective of reducing energy use by more than 30% at a cost below the target of 56 mills/kWh (in 1991 dollars). Based on results from the first 12 calibrated simulation models, 29 of the 66 energy-efficiency measures, or 44%, met the levelized cost criterion. Despite the lower energy savings from individual measures, the energy-use intensities of the buildings are lower than other regional comparison data for new buildings. The authors review factors that contribute to the uncertainty regarding measured savings and suggest methods to improve future evaluations.

SciTech Connect

The conversion efficiency of ultra short-pulse laser radiation to K-{alpha} x-rays has been measured for various chlorine-containing targets to be used as x-ray scattering probes of dense plasmas. The spectral and temporal properties of these sources will allow spectrally-resolved x-ray scattering probing with picosecond temporal resolution required for measuring the plasma conditions in inertial confinement fusion experiments. Simulations of x-ray scattering spectra from these plasmas show that fuel capsule density, capsule ablator density, and shock timing information may be inferred.

Measured impacts of high efficiency domestic clothes washers in a community  

SciTech Connect

The US market for domestic clothes washers is currently dominated by conventional vertical-axis washers that typically require approximately 40 gallons of water for each wash load. Although the current market for high efficiency clothes washers that use much less water and energy is quite small, it is growing slowly as manufacturers make machines based on tumble action, horizontal-axis designs available and as information about the performance and benefits of such machines is developed and made available to consumers. To help build awareness of these benefits and to accelerate markets for high efficiency washers, the Department of Energy (DOE), under its ENERGY STAR{reg_sign} Program and in cooperation with a major manufacturers of high efficiency washers, conducted a field evaluation of high efficiency washers using Bern, Kansas as a test bed. Baseline washing machine performance data as well as consumer washing behavior were obtained from data collected on the existing machines of more than 100 participants in this instrumented study. Following a 2-month initial study period, all conventional machines were replaced by high efficiency, tumble-action washers, and the study continued for 3 months. Based on measured data from over 20,000 loads of laundry, the impact of the washer replacement on (1) individual customers` energy and water consumption, (2) customers` laundry habits and perceptions, and (3) the community`s water supply and waste water systems were determined. The study, its findings, and how information from the experiment was used to improve national awareness of high efficiency clothes washer benefits are described in this paper.

4. Title and Subtitle 5. Report Date MEASURING THE EQUITY AND EFFICIENCY OF RAMP METERS  

E-Print Network (OSTI)

Traffic congestion has become an increasingly serious problem in many cities. Ramp metering, which maintains smooth freeway mainline flow by limiting vehicle entry at entrance ramps, has been proposed and implemented in a number of metropolitan areas in and outside the U.S. to mitigate freeway congestion. This study aims to develop both efficient and equitable freeway ramp control strategies. Traffic conditions with and without ramp metering are evaluated on several representative freeways in the Twin Cities with a comprehensive set of performance measures. A unified theory for ramp metering is proposed based on a linear programming model of freeway traffic dynamics. The most efficient ramp control algorithm is found to be also the least equitable one. A novel control objective, minimizing weighted or perceived travel time, is therefore proposed to balance efficiency and equity objectives of ramp metering. This research also develops a new family of applicable ramp metering strategies, which consider both efficiency and equity, and are demonstrated in a microscopic traffic simulator. Future studies should compare various traffic control methods under the analytical framework proposed in this report. Researchers should also pursue field experiments of the proposed multi-objective ramp control strategies.

An examination of scale-dependent resource use by Eastern Hognose snakes in southcentral New Hampshire.  

Science Conference Proceedings (OSTI)

The decline of many snake populations is attributable to habitat loss, and knowledge of habitat use is critical to their conservation. Resource characteristics (e.g., relative availability of different habitat types, soils, and slopes) within a landscape are scale-dependent and may not be equal across multiple spatial scales. Thus, it is important to identify the relevant spatial scales at which resource selection occurs. We conducted a radiotelemetry study of eastern hognose snake (Heterodon platirhinos) home range size and resource use at different hierarchical spatial scales. We present the results for 8 snakes radiotracked during a 2-year study at New Boston Air Force Station (NBAFS) in southern New Hampshire, USA, where the species is listed by the state as endangered. Mean home range size (minimum convex polygon) at NBAFS (51.7 {+-} 14.7 ha) was similar to that reported in other parts of the species range. Radiotracked snakes exhibited different patterns of resource use at different spatial scales. At the landscape scale (selection of locations within the landscape), snakes overutilized old-field and forest edge habitats and underutilized forested habitats and wetlands relative to availability. At this scale, snakes also overutilized areas containing sandy loam soils and areas with lower slope (mean slope = 5.2% at snake locations vs. 6.7% at random locations). We failed to detect some of these patterns of resource use at the home range scale (i.e., within the home range). Our ability to detect resource selection by the snakes only at the landscape scale is likely the result of greater heterogeneity in macrohabitat features at the broader landscape scale. From a management perspective, future studies of habitat selection for rare species should include measurement of available habitat at spatial scales larger than the home range. We suggest that the maintenance of open early successional habitats as a component of forested landscapes will be critical for the persistence of eastern hognose snake populations in the northeastern United States.

Characterization of Computational Grid Resources Using Low-level Benchmarks  

E-Print Network (OSTI)

An important factor that needs to be taken into account by end-users and systems (schedulers, resource brokers, policy brokers) when mapping applications to the Grid, is the performance capacity of hardware resources attached to the Grid and made available through its Virtual Organizations (VOs). In this paper, we examine the problem of characterizing the performance capacity of Grid resources using benchmarking. We examine the conditions under which such characterization experiments can be implemented in a Grid setting and present the challenges that arise in this context. We specify a small number of performance metrics and propose a suite of micro-benchmarks to estimate these metrics for clusters that belong to large Virtual Organizations. We describe GridBench, a tool developed to administer benchmarking experiments, publish their results, and produce graphical representations of their metrics. We describe benchmarking experiments conducted with, and published through GridBench, and show how they can help end-users assess the performance capacity of resources that belong to a target Virtual Organization. Finally, we examine the advantages of this approach over solutions implemented currently in existing Grid infrastructures. We conclude that it is essential to provide benchmarking services in the Grid infrastructure, in order to enable the attachment of performance-related metadata to resources belonging to Virtual Organizations and the retrieval of such metadata by end-users and other Grid systems. 1

Recommendations for 15% Above-Code Energy Efficiency Measures for Residential Buildings  

E-Print Network (OSTI)

This report presents detailed information about the recommendations for achieving 15% above-code energy performance for single-family residences. The analysis was performed using a simulation model of an International Energy Conservation Code (IECC)-compliant, single family residence in Houston, Texas. To accomplish the 15% annual energy use reductions, twelve measures were considered including: tankless water heater, solar domestic water heating system, natural gas water heater without the standing pilot light, HVAC system including ducts in the conditioned space, improved duct sealing, increased air tightness, window shading and redistribution, improved window performance, and improved heating and cooling system efficiency. After the total annual energy use was determined for each measure, they were then grouped to accomplish a 15% total annual energy use reduction.

Costs and benefits from utility-funded commissioning of energy- efficiency measures in 16 buildings  

SciTech Connect

This paper describes the costs and savings of commissioning of energy- efficiency measures in 16 buildings. A total of 46 EEMs were commissioned for all 16 buildings and 73 deficiencies were corrected. On average, commissioning was marginally cost effective on energy savings alone, although the results were mixed among all 16 buildings. When considered as a stand-alone measure, the median simple payback time of 6.5 years under the low energy prices in the Pacific Northwest. Under national average prices the median payback time is about three years. In estimating the present value of the energy savings from commissioning we considered low and high lifetimes for the persistence of savings from deficiency corrections. Under the low- lifetime case the average present value of the energy savings ($0. 21/ft{sup 2}) were about equal to the average commissioning costs ($0. 23/ft{sup 2}). Under the high-lifetime case the savings ($0.51/ft{sup 2}) were about twice the costs. Again, the savings would be about twice as large under national average prices. The results are subject to significant uncertainty because of the small sample size and lack of metered data in the evaluation. However, the findings suggest that investments in commissioning pay off. Building owners want buildings that work as intended, and are comfortable, healthy, and efficient. It is likely that the non-energy benefits, which are difficult to quantify, are larger than the energy-savings benefits.

Measuring and tuning energy efficiency on large scale high performance computing platforms.  

Science Conference Proceedings (OSTI)

Recognition of the importance of power in the field of High Performance Computing, whether it be as an obstacle, expense or design consideration, has never been greater and more pervasive. While research has been conducted on many related aspects, there is a stark absence of work focused on large scale High Performance Computing. Part of the reason is the lack of measurement capability currently available on small or large platforms. Typically, research is conducted using coarse methods of measurement such as inserting a power meter between the power source and the platform, or fine grained measurements using custom instrumented boards (with obvious limitations in scale). To collect the measurements necessary to analyze real scientific computing applications at large scale, an in-situ measurement capability must exist on a large scale capability class platform. In response to this challenge, we exploit the unique power measurement capabilities of the Cray XT architecture to gain an understanding of power use and the effects of tuning. We apply these capabilities at the operating system level by deterministically halting cores when idle. At the application level, we gain an understanding of the power requirements of a range of important DOE/NNSA production scientific computing applications running at large scale (thousands of nodes), while simultaneously collecting current and voltage measurements on the hosting nodes. We examine the effects of both CPU and network bandwidth tuning and demonstrate energy savings opportunities of up to 39% with little or no impact on run-time performance. Capturing scale effects in our experimental results was key. Our results provide strong evidence that next generation large-scale platforms should not only approach CPU frequency scaling differently, but could also benefit from the capability to tune other platform components, such as the network, to achieve energy efficient performance.

Recommendations for 2009 IECC 15% Above Code Energy Efficiency Measures for Residential Buildings  

E-Print Network (OSTI)

In the 79th Legislature (2005) the Energy Systems Laboratory was required to develop three alternative methods for achieving 15% above-code energy savings in new residential, commercial and industrial construction. The Laboratory continues to work closely with code officials, energy raters, manufacturers, state officials and other stakeholders to develop cost effective energy efficiency measures. This report presents detailed information about the recommendations for achieving 15% above-code energy performance, which are based on the 2009 International Energy Conservation Code (IECC), for single-family residences across the State of Texas. To estimate above-code savings (%) of energy efficiency measures, total source energy savings from heating, cooling, lighting, equipment, and DHW were considered for emissions reductions determination. The recommendations were developed for three 2009 IECC climate zones in Texas along with simple payback calculations. This information is useful to homebuilders, utility demand side energy managers, homeowners and others who wish to construct residential buildings that exceed the minimum national energy code requirements. The analysis was performed using an ESL simulation model based on the DOE-2.1e simulation of a 2009 IECC code-compliant, single family residence and the appropriate TMY2 weather files for seventeen counties in Texas for which TMY2 data is available. According to 2009 IECC Climate Zone, seventeen counties were categorized into three climate zones: Climate Zone 2, 3, and 4, and the 2009 IECC code-compliance base-case models were constructed for each climate zone. Two options based on the choice of heating fuel type were considered: (a) natural gas (gas-fired furnace for space heating, and gas water heater for domestic water heating), and (b) electricity (heat pump for space heating, and electric water heater for domestic water heating). A total of eighteen measures based on the energy savings above the base-case house were selected. These measures include building envelope and fenestration, HVAC system, domestic hot water (DHW) system, lighting and renewable options. The implementation costs of each individual measure were also calculated along with simple payback calculations. These measures were then combined to achieve the total source energy savings of the group is 15% above the base-case 2009 code-compliant house. As a result, three example combinations were proposed for each base case ((a) electric/gas house and (b) all-electric house) in each climate zone. Each combination was formed to have a different payback period. Finally, the corresponding emissions savings of each combination were calculated based on the eGrid for Texas.

Commissioning of energy-efficiency measures: Costs and benefits for 16 buildings  

SciTech Connect

Building systems and energy-efficiency measures (EEMs) often don`t perform as well in practice as expected at the design stage. This fact has become clear to many organizations concerned with ensuring building performance. What to do about these problems is less clear. Several electric utilities around the U.S. have begun to take action to address the start-up, control, and operational problems that are found in nearly every building. One of the most beneficial periods to intervene in the building life cycle is during the start-up phase of a now building. Building commissioning during start up is such an intervention. Commissioning can be defined as: a set of procedures, responsibilities, and methods to advance a system from static installation to full working order in accordance with design intent. In broad terms, commissioning can extend from design reviews through operations and maintenance planning and training. With such a broad scope aimed at the entire building life cycle, commissioning is often likened to {open_quotes}Total Quality Management{close_quotes} Yet the heart of commissioning are the procedures developed and executed to ensure that all building systems function as intended. The incorporation of energy-efficiency criteria into building commissioning is a new development.

Equally important is to determine how well the selection is done so that procedures can be used to optimize the selection. One such method of collision event selection is known as the momentum imbalance trigger at the CMS detector at the LHC for use in a search for new particles from an extension of the standard model. In this thesis, We measure the efficiency as a function of the trigger as well as the effect the number of collisions that occur at the same time has on its performance.

Information Resources: Using the Street and Parking Facility Lighting  

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

Using the Street and Parking Facility Lighting Retrofit Financial Analysis Tool Using the Street and Parking Facility Lighting Retrofit Financial Analysis Tool This August 22, 2013 webinar provided a guided walk-through of the Street and Parking Facility Lighting Retrofit Financial Analysis Tool. Developed by a partnership of the DOE Municipal Solid-State Street Lighting Consortium, the Clinton Climate Initiative/C40, and the DOE Federal Energy Management Program, the Excel-based tool assists with the financial analysis of retrofitting street and parking facility lighting with more efficient alternatives. During the webinar, Doug Elliott of Pacific Northwest National Laboratory discussed how the tool can be used to evaluate costs and benefits associated with converting to more efficient street and parking facility lighting and how property owners, city and other government agencies, utilities, and energy efficiency organizations can use the tool to compute annualized energy and energy-cost savings, maintenance savings, greenhouse gas reductions, net present value, and simple payback associated with potential lighting upgrades.

A Measurement Management Technology for Improving Energy Efficiency in Data Centers and Telecommunication Facilities  

SciTech Connect

Data center (DC) electricity use is increasing at an annual rate of over 20% and presents a concern for the Information Technology (IT) industry, governments, and the society. A large fraction of the energy use is consumed by the compressor cooling to maintain the recommended operating conditions for IT equipment. The most common way to improve the DC efficiency is achieved by optimally provisioning the cooling power to match the global heat dissipation in the DC. However, at a more granular level, the large range of heat densities of today's IT equipment makes the task of provisioning cooling power optimized to the level of individual computer room air conditioning (CRAC) units much more challenging. Distributed sensing within a DC enables the development of new strategies to improve energy efficiency, such as hot spot elimination through targeted cooling, matching power consumption at rack level with workload schedule, and minimizing power losses. The scope of Measurement and Management Technologies (MMT) is to develop a software tool and the underlying sensing technology to provide critical decision support and control for DC and telecommunication facilities (TF) operations. A key aspect of MMT technology is integration of modeling tools to understand how changes in one operational parameter affect the overall DC response. It is demonstrated that reduced ordered models for DC can generate, in less than 2 seconds computational time, a three dimensional thermal model in a 50 kft{sup 2} DC. This rapid modeling enables real time visualization of the DC conditions and enables 'what if' scenarios simulations to characterize response to 'disturbances'. One such example is thermal zone modeling that matches the cooling power to the heat generated at a local level by identifying DC zones cooled by a specific CRAC. Turning off a CRAC unit can be simulated to understand how the other CRAC utilization changes and how server temperature responds. Several new sensing technologies were added to the existing MMT platform: (1) air contamination (corrosion) sensors, (2) power monitoring, and (3) a wireless environmental sensing network. All three technologies are built on cost effective sensing solutions that increase the density of sensing points and enable high resolution mapping of DCs. The wireless sensing solution enables Air Conditioning Unit (ACU) control while the corrosion sensor enables air side economization and can quantify the risk of IT equipment failure due to air contamination. Validation data for six test sites demonstrate that leveraging MMT energy efficiency solutions combined with industry best practices results in an average of 20% reduction in cooling energy, without major infrastructure upgrades. As an illustration of the unique MMT capabilities, a data center infrastructure efficiency (DCIE) of 87% (industry best operation) was achieved. The technology is commercialized through IBM System and Technology Lab Services that offers MMT as a solution to improve DC energy efficiency. Estimation indicates that deploying MMT in existing DCs can results in an 8 billion kWh savings and projection indicates that constant adoption of MMT can results in obtainable savings of 44 billion kWh in 2035. Negotiations are under way with business partners to commercialize/license the ACU control technology and the new sensor solutions (corrosion and power sensing) to enable third party vendors and developers to leverage the energy efficiency solutions.

Efficient and reliable 3D dose quality assurance for IMRT by combining independent dose calculations with measurements  

SciTech Connect

Purpose: Advanced radiotherapy treatments require appropriate quality assurance (QA) to verify 3D dose distributions. Moreover, increase in patient numbers demand efficient QA-methods. In this study, a time efficient method that combines model-based QA and measurement-based QA was developed; i.e., the hybrid-QA. The purpose of this study was to determine the reliability of the model-based QA and to evaluate time efficiency of the hybrid-QA method. Methods: Accuracy of the model-based QA was determined by comparison of COMPASS calculated dose with Monte Carlo calculations for heterogeneous media. In total, 330 intensity modulated radiation therapy (IMRT) treatment plans were evaluated based on the mean gamma index (GI) with criteria of 3%/3mm and classification of PASS (GI {<=} 0.4), EVAL (0.4 < GI > 0.6), and FAIL (GI {>=} 0.6). Agreement between model-based QA and measurement-based QA was determined for 48 treatment plans, and linac stability was verified for 15 months. Finally, time efficiency improvement of the hybrid-QA was quantified for four representative treatment plans. Results: COMPASS calculated dose was in agreement with Monte Carlo dose, with a maximum error of 3.2% in heterogeneous media with high density (2.4 g/cm{sup 3}). Hybrid-QA results for IMRT treatment plans showed an excellent PASS rate of 98% for all cases. Model-based QA was in agreement with measurement-based QA, as shown by a minimal difference in GI of 0.03 {+-} 0.08. Linac stability was high with an average GI of 0.28 {+-} 0.04. The hybrid-QA method resulted in a time efficiency improvement of 15 min per treatment plan QA compared to measurement-based QA. Conclusions: The hybrid-QA method is adequate for efficient and accurate 3D dose verification. It combines time efficiency of model-based QA with reliability of measurement-based QA and is suitable for implementation within any radiotherapy department.

Energy-efficient new commercial buildings in the Northwest region: a compilation of measured data  

SciTech Connect

We have collected and analyzed data for 36 new commercial buildings designed to be energy-efficient in the Northwest. Eighteen buildings are offices; the remainder are mostly retail buildings, and schools. The data were collected and analyzed to evaluate the building energy standards adopted by the Northwest Power Planning Council in the Northwest Conservation and Electric Power Plan. Almost half of the buildings are operating at energy levels under the Council's estimates for new efficient commercial buildings. There is, however, a large range of energy intensities. The average office building consumes 54 kBtu/ftS-yr (in site energy units), while the average small office uses only 43 kBtu/ftS-yr. Energy consumption for the eight retail buildings ranges from 47 kBtu/fS-yr to 134 kBtu/ftS-yr.

Measured energy performance of a US-China demonstrationenergy-efficient office building  

SciTech Connect

In July 1998, the U.S. Department of Energy (USDOE) and China's Ministry of Science of Technology (MOST) signed a Statement of Work (SOW) to collaborate on the design and construction of an energy-efficient demonstration office building and design center to be located in Beijing. The proposed 13,000 m{sup 2} (140,000 ft{sup 2}) nine-story office building would use U.S. energy-efficient materials, space-conditioning systems, controls, and design principles that were judged to be widely replicable throughout China. The SOW stated that China would contribute the land and provide for the costs of the base building, while the U.S. would be responsible for the additional (or marginal) costs associated with the package of energy efficiency and renewable energy improvements to the building. The project was finished and the building occupied in 2004. Using DOE-2 to analyze the energy performance of the as-built building, the building obtained 44 out of 69 possible points according to the Leadership in Energy and Environmental Design (LEED) rating, including the full maximum of 10 points in the energy performance section. The building achieved a LEED Gold rating, the first such LEED-rated office building in China, and is 60% more efficient than ASHRAE 90.1-1999. The utility data from the first year's operation match well the analysis results, providing that adjustments are made for unexpected changes in occupancy and operations. Compared with similarly equipped office buildings in Beijing, this demonstration building uses 60% less energy per floor area. However, compared to conventional office buildings with less equipment and window air-conditioners, the building uses slightly more energy per floor area.

More than fifteen years after the launch of programs in theU.K. and U.S., industry still offers one of the largest opportunities forenergy savings worldwide. The International Energy Agency (IEA) estimatesthe savings potential from cost-optimization of industrial motor-drivensystems alone at 7 percent of global electricity use. The U.S. Departmentof Energy (USDOE) Industrial Technologies Program estimates 7 percentsavings potential in total US industrial energy use through theapplication of proven best practice. Simple paybacks for these types ofprojects are frequently two years or less. The technology required toachieve these savings is widely available; the technical skills requiredto identify energy saving opportunities are known and transferable.Although programs like USDOE's Best Practices have been highlysuccessful, most plants, as supported by 2002 MECS data, remain eitherunaware or unmotivated to improve their energy efficiency--as evidencedby the 98 percent of US industrial facilities reporting to MECS say thatthey lack a full-time energy manager. With the renewed interest in energyefficiency worldwide and the emergence of carbon trading and newfinancial instruments such as white certificates1, there is a need tointroduce greater transparency into the way that industrial facilitiesidentify, develop, and document energy efficiency projects. Historically,industrial energy efficiency projects have been developed by plantengineers, frequently with assistance from consultants and/or supplierswith highly specialized technical skills. Under this scenario,implementation of energy efficiency improvements is dependent onindividuals. These individuals typically include "champions" within anindustrial facility or corporation, working in cooperation withconsultants or suppliers who have substantial knowledge based on years ofexperience. This approach is not easily understood by others without thisspecialized technical knowledge, penetrates the market fairly slowly, andhas no assurance of persistence, since champions may leave the company orbe reassigned after project completion.This paper presents an alternatescenario that builds on the body of expert knowledge concerning energymanagement best practices and the experience of industrial champions toengage industry in continuous energy efficiency improvement at thefacility rather than the individual level. Under this scenario,standardized methodologies for applying and validating energy managementbest practices in industrial facilities will be developed through aconsensus process involving both plant personnel and specializedconsultants and suppliers. The resulting protocols will describe aprocess or framework for conducting an energy savings assessment andverifying the results that will be transparent to policymakers, managers,and the financial community, and validated by a third-party organization.Additionally, a global dialogue is being initiated by the United NationsIndustrial Development Organization (UNIDO) concerning the development ofan international industrial energy management standard that would be ISOcompatible.

Thelong term goal of this voluntary, industry designed certification programis to develop a transparent, globally accepted system for validatingenergy efficiency projects and management practices.

National Energy Efficiency Evaluation, Measurement and Verification (EM&V) Standard: Scoping Study of Issues and Implementation Requirements  

Science Conference Proceedings (OSTI)

This report is a scoping study that identifies issues associated with developing a national evaluation, measurement and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities. The objectives of this study are to identify the scope of such a standard and define EM&V requirements and issues that will need to be addressed in a standard. To explore these issues, we provide and discuss: (1) a set of definitions applicable to an EM&V standard; (2) a literature review of existing guidelines, standards, and 'initiatives' relating to EM&V standards as well as a review of 'bottom-up' versus 'top-down' evaluation approaches; (3) a summary of EM&V related provisions of two recent federal legislative proposals (Congressman Waxman's and Markey's American Clean Energy and Security Act of 2009 and Senator Bingaman's American Clean Energy Leadership Act of 2009) that include national efficiency resource requirements; (4) an annotated list of issues that that are likely to be central to, and need to be considered when, developing a national EM&V standard; and (5) a discussion of the implications of such issues. There are three primary reasons for developing a national efficiency EM&V standard. First, some policy makers, regulators and practitioners believe that a national standard would streamline EM&V implementation, reduce costs and complexity, and improve comparability of results across jurisdictions; although there are benefits associated with each jurisdiction setting its own EM&V requirements based on their specific portfolio and evaluation budgets and objectives. Secondly, if energy efficiency is determined by the US Environmental Protection Agency to be a Best Available Control Technology (BACT) for avoiding criteria pollutant and/or greenhouse gas emissions, then a standard can be required for documenting the emission reductions resulting from efficiency actions. The third reason for a national EM&V standard is that such a standard is likely to be required as a result of future federal energy legislation that includes end-use energy efficiency, either as a stand-alone energy-efficiency resource standard (EERS) or as part of a clean energy or renewable energy standard. This study is focused primarily on this third reason and thus explores issues associated with a national EM&V standard if energy efficiency is a qualifying resource in federal clean energy legislation. Developing a national EM&V standard is likely to be a lengthy process; this study focuses on the critical first step of identifying the issues that must be addressed in a future standard. Perhaps the most fundamental of these issues is 'how good is good enough?' This has always been the fundamental issue of EM&V for energy efficiency and is a result of the counter-factual nature of efficiency. Counter-factual in that savings are not measured, but estimated to varying degrees of accuracy by comparing energy consumption after a project (program) is implemented with what is assumed to have been the consumption of energy in the absence of the project (program). Therefore, the how good is good enough question is a short version of asking how certain does one have to be of the energy savings estimate that results from EM&V activities and is that level of certainty properly balanced against the amount of effort (resources, time, money) that is utilized to obtain that level of certainty. The implication is that not only should energy efficiency investments be cost-effective, but EM&V investments should consider risk management principles and thus also balance the costs and value of information derived from EM&V (EM&V should also be cost-effective).

Regional Energy Baselines and Measurement and Verification Protocols: Subtask 3.1 for the Southern Energy Efficiency Center  

E-Print Network (OSTI)

The Southern Energy Efficiency Center (SEEC) was established to substantially increase the deployment of high-performance “beyond-code” buildings across the southern region of the U.S. It is funded by the U.S. Department of Energy (DOE) Building Technologies Program, and administered by the National Energy Technology Laboratory. The goal of the first 18-month phase was to address efficiency goals of states, utilities, and various energy-efficiency programs. In order to achieve this goal, the project efforts included defining the baseline energy patterns within the project region, as well as the measurement and verification (M&V) protocols for use in determining the efficiency improvements SEEC, state and USDOE efforts with respect to that baseline. This work is defined under the SEEC Subtask 3.1 Define Regional Baselines and Measurement & Verification Protocols. This report presents preliminary deliverables of this subtask developed and documented by the Energy Systems Laboratory (ESL) for use by the SEEC member state region. The primary goal of this subtask is to provide the state energy offices with a comparison tool of energy use either by total or per-capita. This tool is expected to allow the state energy offices to compare their energy use pattern against other states’ and the national average energy use by end-use sector. In addition, they can use this tool for a comparison of energy use within their states by end-use and by fuel-source. Another goal of this subtask is to demonstrate the usability of public-available data such as the U.S. Department of Energy’s Energy Information Agency (DOE EIA) data sets and the U.S. Census Bureau data sets. This approach has been successfully demonstrated by ESL as part of the Comptroller of Public Accounts and the State Energy Conservation Office report on Texas Energy Future. Limited preliminary analysis of the data was made since it was not a project goal. The data provides the basis by which extensive state by state analysis can begin. In addition, the recommended measurement and verification (M&V) protocols for an individual building or facility, ASHRAE/CIBSE/USGBC Performance Measurement Protocols (PMP) for Commercial Buildings, can be used as a bottom-up approach for energy efficiency improvements of buildings within the SEEC 12-state region.

Importance of Measurement: The Impact of Power Quality in Energy Efficiency  

E-Print Network (OSTI)

To implement sustainable and green initiatives in a building it is vital to have a means of measuring and verifying its performance. This is done by the introduction of intelligent utility and energy metering to the facility that would become its eyes and ears. The principle is you cannot control what you cannot measure. Looking closer at the power side, the inefficiencies caused by power quality issues such as power factor and harmonics have often been easily overlooked due to the traditional focus on equipment performance optimisation, rather than on the quality of power which is essential for the operation of any electrical equipment. This paper analyses power factor and harmonics problem areas and offers practical approaches for improvements.

Recommendations for 15% Above-Code Energy Efficiency Measures for Commercial Office Buildings  

E-Print Network (OSTI)

This report presents detailed information about the recommendations for achieving 15% above-code energy performance for commercial office buildings complying with ASHRAE Standard 90.1-19991. To accomplish the 15% annual energy consumption reductions, ten measures were considered. After energy savings were determined for each measure, they were then placed in several groups to accomplish a minimum of 15% total annual energy consumption reduction. The analysis in this paper uses the total annual energy consumption of a simulated commercial building to determine the 15% above-code recommendations. The analysis also reports end-use energy use, including: heating, cooling, domestic hot water use, fans, heat rejection, equipment and lighting loads, and miscellaneous loads as defined by the BEPS and BEPU reports from the DOE-2 program. Since the 15% above-code savings use annual energy cost savings, these same measures will report greater savings when compared against total heating and cooling loads, which has been used in other above-code program recommendations.

Overview of existing residential energy-efficiency rating systems and measuring tools  

SciTech Connect

Three categories of rating systems/tools were identified: prescriptive, calculational, and performance. Prescriptive systems include rating systems that assign points to various conservation features. Most systems that have been implemented to date have been prescriptive systems. The vast majority of these are investor-owned utility programs affiliated with the National Energy Watch program of the Edison Electric Institute. The calculational category includes computational tools that can be used to estimate energy consumption. This estimate could then be transformed, probably by indexing, into a rating. The available computational tools range from very simple to complex tools requiring use of a main-frame computer. Performance systems refer to residential energy-efficiency ratings that are based on past fuel consumption of a home. There are few of these systems. For each identified system/tool, the name, address, and telephone number of the developer is included. In addition, relevant publications discussing the system/tool are cited. The extent of field validation/verification of individual systems and tools is discussed. In general, there has been little validation/verification done. A bibliography of literature relevant to the use and implementation of a home energy rating system is also included.

Simulator Developed to Drastically Reduce Time of Multijunction PV Device Efficiency Measurements (Fact Sheet), NREL Highlights, Research & Development  

DOE Green Energy (OSTI)

NREL's new simulator helps speed up research in the race to improve photovoltaic efficiency. Scientists at the National Renewable Energy Laboratory (NREL) needed a quick and accurate method to predict energy generated from multijunction photovoltaic (PV) test devices. This method had to take into account the nonlinear behavior of multijunction PV. NREL achieved this by developing the One-Sun Multi-Source Simulator (OSMSS), which reduces the time for this type of reference spectrum efficiency measurement from hours or days to minutes. The OSMSS is an automated, spectrally adjustable light source that builds a unique simulator spectrum that causes a multijunction PV device to behave as it would under a reference spectrum. This new simulator consists of four light sources separated into nine wavelength bands between 350 and 2,000 nm. The irradiance in each band is adjustable from zero to about 1.5 suns. All bands are recombined via optical fibers and integrating optics to produce a nearly 10 cm x 10 cm uniform spot. The operator simply links the OSMSS to the quantum efficiency data for the test device, and the OSMSS does the rest. The OSMSS can also determine the power as a function of the spectral irradiance (beyond the reference spectra), total irradiance, and temperature. Major components of the system were built to NREL specification by LabSphere, Inc. NREL developed a new, fully automated tool that rapidly builds a spectrum under which all junctions of a multijunction PV device behave as they would under a reference spectrum. Such a spectrum is essential to properly characterize multijunction devices. The OSMSS reduces the time for building spectra for current vs. voltage measurements from hours or days to minutes. This makes it possible to quickly characterize a multijunction device under many different conditions. The OSMSS will be an important tool to help predict the yearly energy output of a multijunction PV device in a particular environment when provided with a range of spectra and temperatures for that location.

Even after years of training and awareness building at thestate and national level, industrial cross-cutting systems (motor-driven,steam, process heating) continue to offer significant opportunities forenergy savings. The US Department of Energy estimates these remainingsavings at more than 7 percent of all industrial energy use. This paperpresents a different approach to promoting industrial system energyefficiency -- providing plant personnel with ready access to data uponwhich to base energy management decisions.In 2005, a Del Monte Foodsfruit processing plant in Modesto, California worked with LawrenceBerkeley National Laboratory (LBNL)to specify and purchase permanentinstrumentation for monitoring their compressed air system. This work,completed as part of a demonstration project under a State TechnologiesAdvancement Collaborative (STAC) grant, was designed to demonstrate theeffectiveness of enterprise energy management (EEM), which is predicatedon the assumption that the energy efficiency of existing, cross-cuttingindustrial systems (motor-driven, steam) can be improved by providingmanagement and operating personnel with real-time data on energy use.

Energy Efficiency Improvement by Measurement and Control: A Case Study of Reheating Furnaces in the Steel Industry  

E-Print Network (OSTI)

The aim of this paper is to analyze the possibilities for energy efficiency improvements through utilization of measurement and automatic control; this includes both direct fuel savings and indirect savings due to product quality improvements. Focus is on energy use in steel reheating furnaces for rolling mills. The demands on the reheating process and the operational conditions that are essential for its control are described. An analysis is made of possible reductions in energy use as a result of improved control. A survey is included of furnace control systems in steel plants; such equipment has been designed and implemented in order to optimize the reheating process. Reports of achieved savings are presented, and demands on measurement and control systems for successful implementation are discussed. Economic analyses, in terms of life cycle costs and estimated savings, are made for three levels of measurement and control systems. Reductions in energy use of up to 20 percent can be expected for the type of process studied, as a result of investments in information technology; it is also concluded that such investments are cost-effective.

Measurement of the ATLAS di-muon trigger efficiency in proton-proton collisions at 7 TeV  

E-Print Network (OSTI)

At the LHC, muons are produced in many final states and used in a variety of analysis, such as Standard Model precision measurements and searches for new physics. The B-physics programme in ATLAS includes the measurement of CP violating effects in B meson decays, the search for rare b decay signatures, as well as the study of the production cross sections. The ATLAS detector can identify muons with high purity in a transverse momentum ($p_{T}$) range from a few GeV to several TeV. In order to achieve a high trigger efficiency for low $p_{T}$ di-muon events and at the same time keep an acceptable trigger rate, dedicated trigger algorithms have been designed and implemented in the trigger menu since the 2010 data taking period. There are two categories of B-physics triggers, one topological and one non-topological. Both of these have been studied and their performance assessed using collision data at $\\sqrt{s}$ = 7 TeV. The performance found with data has been verified with simulated events.

The Joint Efficient Dark-energy Investigation (JEDI): Measuring the cosmic expansion history from type Ia supernovae  

E-Print Network (OSTI)

JEDI (Joint Efficient Dark-energy Investigation) is a candidate implementation of the NASA-DOE Joint Dark Energy Mission (JDEM). JEDI will probe dark energy in three independent methods: (1) type Ia supernovae, (2) baryon acoustic oscillations, and (3) weak gravitational lensing. In an accompanying paper, an overall summary of the JEDI mission is given. In this paper, we present further details of the supernova component of JEDI. To derive model-independent constraints on dark energy, it is important to precisely measure the cosmic expansion history, H(z), in continuous redshift bins from z \\~ 0-2 (the redshift range in which dark energy is important). SNe Ia at z > 1 are not readily accessible from the ground because the bulk of their light has shifted into the near-infrared where the sky background is overwhelming; hence a space mission is required to probe dark energy using SNe. Because of its unique near-infrared wavelength coverage (0.8-4.2 microns), JEDI has the advantage of observing SNe Ia in the rest frame J band for the entire redshift range of 0 energy are discussed, with special emphasis on the improved precision afforded by the rest frame near-infrared data.

How Does Your Data Center Measure Up? Energy Efficiency Metrics and Benchmarks for Data Center Infrastructure Systems  

SciTech Connect

Data centers are among the most energy intensive types of facilities, and they are growing dramatically in terms of size and intensity [EPA 2007]. As a result, in the last few years there has been increasing interest from stakeholders - ranging from data center managers to policy makers - to improve the energy efficiency of data centers, and there are several industry and government organizations that have developed tools, guidelines, and training programs. There are many opportunities to reduce energy use in data centers and benchmarking studies reveal a wide range of efficiency practices. Data center operators may not be aware of how efficient their facility may be relative to their peers, even for the same levels of service. Benchmarking is an effective way to compare one facility to another, and also to track the performance of a given facility over time. Toward that end, this article presents the key metrics that facility managers can use to assess, track, and manage the efficiency of the infrastructure systems in data centers, and thereby identify potential efficiency actions. Most of the benchmarking data presented in this article are drawn from the data center benchmarking database at Lawrence Berkeley National Laboratory (LBNL). The database was developed from studies commissioned by the California Energy Commission, Pacific Gas and Electric Co., the U.S. Department of Energy and the New York State Energy Research and Development Authority.

Review of water, lighting, and cooling energy efficiency measures for low-income homes located in warm climates  

SciTech Connect

In support of the U.S. Department of Energy`s Weatherization Assistance Program, Oak Ridge National Laboratory has performed a literature review of weatherization measures applicable for homes located in warm climate regions. Sources for this information included: (1) documented engineering estimates, (2) vendor information, (3) reported performance from research and field tests, and (4) direct discussions with researchers, vendors, and field reporters. Estimated savings are extrapolated from reported energy savings and applied to the end-use energy consumption for low-income homes reported by the Energy Information Administration. Additionally, installation costs, savings-to-investment ratios, and parameters indicating performance sensitivity to issues such as occupancy, construction, client education, and maintenance requirements are presented. The report is comprised of two sections: (1) an overview of measure performance, and (2) an appendix. The overview of measures is in a tabular format, which allows for quick reference. More detailed discussions and references for each measure are presented in the Appendix and it is highly recommended that these be reviewed prior to measure selection.

An Efficient Strategy to Select Targets for Gas-Dynamical Measurements of Black Hole Masses Using the Hubble Space Telescope  

E-Print Network (OSTI)

Gas-dynamical studies using the Hubble Space Telescope are an integral component for future progress in the search for massive black holes in galactic nuclei. Here we present an extensive set of gas rotation curves obtained with the Space Telescope Imaging Spectrograph for the central regions of 23 disk galaxies. We find that the bulges of randomly selected, nearby spiral and S0 galaxies generally do not contain well-defined gaseous disks. Only 15%-20% of disk galaxies have regular, symmetric velocity fields useful for dynamical analysis. Through comparison of the kinematics with Hubble Space Telescope images of the nuclear regions, we show that the probability of success can be significantly boosted by preselecting objects whose central dust lanes follow a well-ordered, circularly symmetric pattern. The dust morphology can be ascertained efficiently by visual inspection of unsharp-masked images.

The Oklahoma Field Test: Air-conditioning electricity savings from standard energy conservation measures, radiant barriers, and high-efficiency window air conditioners  

SciTech Connect

A field test Involving 104 houses was performed in Tulsa, Oklahoma, to measure the air-conditioning electricity consumption of low-income houses equipped with window air conditioners, the reduction in this electricity consumption attributed to the installation of energy conservation measures (ECMS) as typically installed under the Oklahoma Weatherization Assistance Program (WAP), and the reduction achieved by the replacement of low-efficiency window air conditioners with high-efficiency units and the installation of attic radiant barriers. Air-conditioning electricity consumption and indoor temperature were monitored weekly during the pre-weatherization period (June to September 1988) and post-weatherization period (May to September 1989). House energy consumption models and regression analyses were used to normalize the air-conditioning electricity savings to average outdoor temperature conditions and the pre-weatherization indoor temperature of each house. The following conclusions were drawn from the study: (1) programs directed at reducing air-conditioning electricity consumption should be targeted at clients with high consumption to improve cost effectiveness; (2) replacing low-efficiency air conditioners with high-efficiency units should be considered an option in a weatherization program directed at reducing air-conditioning electricity consumption; (3) ECMs currently being installed under the Oklahoma WAP (chosen based on effectiveness at reducing space-heating energy consumption) should continue to be justified based on their space-heating energy savings potential only; and (4) attic radiant barriers should not be included in the Oklahoma WAP if alternatives with verified savings are available or until further testing demonstrates energy savings or other benefits in this typo of housing.

Measurement of transmission efficiency for 400 MeV proton beam through collimator at Fermilab MuCool Test Area using Chromox-6 scintillation screen  

SciTech Connect

The MuCool Test Area (MTA) at Fermilab is a facility to develop the technology required for ionization cooling for a future Muon Collider and/or Neutrino Factory. As part of this research program, feasibility studies of various types of RF cavities in a high magnetic field environment are in progress. As a unique approach, we have tested a RF cavity filled with a high pressure hydrogen gas with a 400 MeV proton beam in an external magnetic field (B = 3 T). Quantitative information about the number of protons passing through this cavity is an essential requirement of the beam test. The MTA is a flammable gas (hydrogen) hazard zone. Due to safety reasons, no active (energized) beam diagnostic instrument can be used. Moreover, when the magnetic field is on, current transformers (toroids) used for beam intensity measurements do not work due to the saturation of the ferrite material of the transformer. Based on these requirements, we have developed a passive beam diagnostic instrumentation using a combination of a Chromox-6 scintillation screen and CCD camera. This paper describes details of the beam profile and position obtained from the CCD image with B = 0 T and B = 3 T, and for high and low intensity proton beams. A comparison is made with beam size obtained from multi-wires detector. Beam transmission efficiency through a collimator with a 4 mm diameter hole is measured by the toroids and CCD image of the scintillation screen. Results show that the transmission efficiency estimated from the CCD image is consistent with the toroid measurement, which enables us to monitor the beam transmission efficiency even in a high magnetic field environment.

A simultaneous measurement of the $b$-tagging efficiency scale factor and the $t\\bar{t}$ Production Cross Section at the Collider Detector at Fermilab  

SciTech Connect

The ability to compare results between Monte Carlo and data is imperative in modern experimental high-energy physics analyses. The b-tagging efficiency Scale Factor (SF) allows for an accurate comparison of b quark identification in data samples and Monte Carlo. This thesis presents a simultaneous measurement of the SF for the SecVtx algorithm and the t{bar t} production cross section using 5.6 fb{sup -1} of p{bar p} collision data at {radical}s = 1.96 TeV collected by the Collider Detector at Fermilab (CDF) experiment. The t{bar t} cross section was measured to be 7.26 {+-} 0.47 pb, consistent with prior CDF analyses. The tight SF value was measured to be 0.925 {+-} 0.032 and the loose SF value was measured at 0.967 {+-} 0.033. These are the most precise SF SecVtx measurements to be performed at CDF to date.

MONITORING POWER PLANT EFFICIENCY USING THE MICROWAVE-EXCITED THERMAL-ACOUSTIC EFFECT TO MEASURE UNBURNED CARBON  

Science Conference Proceedings (OSTI)

The objective of this project is to explore microwave-excited thermal-acoustic (META) phenomena for quantitative analysis of granular and powdered materials, with the culmination of the research to be an on-line carbon-in-ash monitor for coal-fired power plants. This technique of analyzing unburned carbon in fly ash could be a less tedious and time consuming method as compared to the traditional LOI manual procedure. Phase 1 of the research focused on off-line single-frequency thermal-acoustic measurements where an off-line fly ash monitor was constructed that could operate as analytical tool to explore instrument and methodology parameters for quantifying the microwave-excited thermal-acoustic effect of carbon in fly ash, and it was determined that the off-line thermal-acoustic technique could predict the carbon content of a random collection of fly ashes with a linear correlation constant of R{sup 2} = 0.778. Much higher correlations are expected for fly ashes generated from a single boiler. Phase 2 of the research developing a methodology to generate microwave spectra of various powders, including fly ash, coal, and inorganic minerals, and to determine if these microwave spectra could be used for chemical analyses. Although different minerals produced different responses, higher resolution microwave spectra would be required to be able to distinguish among minerals. Phase 3 of the research focused on the development of an on-line fly ash monitor that could be adapted to measure either a thermal-acoustic or thermal-elastic response to due microwave excitation of fly ash. The thermal-acoustic response was successfully employed for this purpose but the thermal-elastic response was too weak to yield a useful on-line device.

Recommendations for 15% Above-Code Energy Efficiency Measures on Implementing Houston Amendments to Single-Family Buildings in Houston Texas  

E-Print Network (OSTI)

This report presents detailed information about the analysis that was performed to calculate the energy saving potential for residential buildings in Houston. In this analysis the energy efficient measures were proposed by the building officials of the City of Houston. Along with the options proposed by the officials, additional measures were selected from the previously-conducted 15% above code energy analysis conducted by the Energy Systems Laboratory for residential houses across the State of Texas. A total of thirty measures were selected based on the energy savings above the base case. These measures were categorized into five groups: Renewable Power Options, Heating Ventilation and Air Conditioning (HVAC), Fenestration, Envelope and Lighting and Domestic Hot Water (DHW) options. The analysis was performed using a simulation model of an International Energy Conservation Code (IECC)-compliant, single family residence in Houston, Texas. Four sets of simulations were considered based on the choice of heating fuel type and thermostat setback: a) natural gas (i.e., gas-fired furnace for space heating, and gas water heater for domestic water heating) with thermostat setback, b) electricity (i.e., heat pump for space heating, and electric water heater for domestic water heating) with thermostat setback, c) natural gas (i.e., gas-fired furnace for space heating, and gas water heater for domestic water heating) without thermostat setback, and d) electricity (i.e., heat pump for space heating, and electric water heater for domestic water heating) without thermostat setback. Individual measures were then categorized into four groups: 2 to 5%, 5 to 10%, and 10 to 15% and above 15% energy savings above base case. Ten grouped measures were then simulated from combining individual measures from the four categories whose combined savings are more than 15% above the base case. The cost of implementation of the individual as well as grouped measures was also calculated along with a simple payback period. The photovoltaic options presented the maximum savings in the approximate range of 15-40% for all base-case houses. The solar thermal option for domestic water heating presented energy savings above 15-20% for all of the base-case houses.

A Measurement of the ATLAS Di-Muon Trigger Efficiency in Proton-Proton Collision at $\\sqrt{s}=7$ TeV  

E-Print Network (OSTI)

The B physics programme of the ATLAS experiment includes measurements of production cross sections, searches for rare B-decay signatures which are sensitive to new physics at the TeV energy scale and studies of CP violation effects in B-events, such as $B_{s}^{0}\\rightarrow J/\\psi \\phi$ and $B_{d}^{0}\\rightarrow J/\\psi K_{s}^{0}$. The key to the detection of these B signals in ATLAS is to achieve a high trigger efficiency for low-$p_{T}$ di-muon events, whilst keeping an acceptable trigger rate. ATLAS developed two separate approaches for triggering on di-muon events from resonances such as $J/\\psi$ and Upsilon ($\\Upsilon$). The first approach is to start from a di-muon trigger selected at Level-1 while the second is based on dedicated Level-2 algorithms. The performance for these triggers has been studied using collision data at $\\sqrt{s}=7$ TeV collected in 2011.

Data are limited for several reasons. As the amount of data collected increases so do the costs of collecting, processing, and analyzing the data. The configuration of certain technologies and processes can also limit the possibility of obtaining microdata. As an example, in the manufacturing sector, some motors are encased in such a way that it is impossible to collect data on the motor unless records have been maintained for the motor. This leads to another reason data are limited--respondent burden. Care has to be taken so that surveys are not so long that participation is discouraged or inaccurate answers are given due to the difficulty and time it takes to obtain the data.

Measure Guideline: Summary of Interior Ducts in New Construction, Including an Efficient, Affordable Method to Install Fur-Down Interior Ducts  

Science Conference Proceedings (OSTI)

This document illustrates guidelines for the efficient installation of interior duct systems in new housing, including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. This document illustrates guidelines for the efficient installation of interior duct systems in new housing. Interior ducts result from bringing the duct work inside a home's thermal and air barrier. Architects, designers, builders, and new home buyers should thoroughly investigate any opportunity for energy savings that is as easy to implement during construction, such as the opportunity to construct interior duct work. In addition to enhanced energy efficiency, interior ductwork results in other important advantages, such as improved indoor air quality, increased system durability and increased homeowner comfort. While the advantages of well-designed and constructed interior duct systems are recognized, the implementation of this approach has not gained a significant market acceptance. This guideline describes a variety of methods to create interior ducts including the fur-up chase method, the fur-down chase method, and interior ducts positioned in sealed attics or sealed crawl spaces. As communication of the intent of an interior duct system, and collaboration on its construction are paramount to success, this guideline details the critical design, planning, construction, inspection, and verification steps that must be taken. Involved in this process are individuals from the design team; sales/marketing team; and mechanical, insulation, plumbing, electrical, framing, drywall and solar contractors.

The comparative impact of the market penetration of energy-efficient measures: A sensitivity analysis of its impact on minority households  

SciTech Connect

A sensitivity study was made of the potential market penetration of residential energy efficiency as energy service ratio (ESR) improvements occurred in minority households, by age of house. The study followed a Minority Energy Assessment Model analysis of the National Energy Strategy projections of household energy consumption and prices, with majority, black, and Hispanic subgroup divisions. Electricity and total energy consumption and expenditure patterns were evaluated when the households` ESR improvement followed a logistic negative growth (i.e., market penetration) path. Earlier occurrence of ESR improvements meant greater discounted savings over the 22-year period.

Efficient universal blind computation  

E-Print Network (OSTI)

We give a cheat sensitive protocol for blind universal quantum computation that is efficient in terms of computational and communication resources: it allows one party to perform an arbitrary computation on a second party's quantum computer without revealing either which computation is performed, or its input and output. The first party's computational capabilities can be extremely limited: she must only be able to create and measure single-qubit superposition states. The second party is not required to use measurement-based quantum computation. The protocol requires the (optimal) exchange of O(J log(N)) single-qubit states, where J is the computational depth and N is the number of qubits needed for the computation.

Towards Efficient Supercomputing: Searching for the Right Efficiency Metric  

Science Conference Proceedings (OSTI)

The efficiency of supercomputing has traditionally been in the execution time. In early 2000 s, the concept of total cost of ownership was re-introduced, with the introduction of efficiency measure to include aspects such as energy and space. Yet the supercomputing community has never agreed upon a metric that can cover these aspects altogether and also provide a fair basis for comparison. This paper exam- ines the metrics that have been proposed in the past decade, and proposes a vector-valued metric for efficient supercom- puting. Using this metric, the paper presents a study of where the supercomputing industry has been and how it stands today with respect to efficient supercomputing.

Refines Efficiency Improvement  

Science Conference Proceedings (OSTI)

Refinery processes that convert heavy oils to lighter distillate fuels require heating for distillation, hydrogen addition or carbon rejection (coking). Efficiency is limited by the formation of insoluble carbon-rich coke deposits. Heat exchangers and other refinery units must be shut down for mechanical coke removal, resulting in a significant loss of output and revenue. When a residuum is heated above the temperature at which pyrolysis occurs (340 C, 650 F), there is typically an induction period before coke formation begins (Magaril and Aksenova 1968, Wiehe 1993). To avoid fouling, refiners often stop heating a residuum before coke formation begins, using arbitrary criteria. In many cases, this heating is stopped sooner than need be, resulting in less than maximum product yield. Western Research Institute (WRI) has developed innovative Coking Index concepts (patent pending) which can be used for process control by refiners to heat residua to the threshold, but not beyond the point at which coke formation begins when petroleum residua materials are heated at pyrolysis temperatures (Schabron et al. 2001). The development of this universal predictor solves a long standing problem in petroleum refining. These Coking Indexes have great potential value in improving the efficiency of distillation processes. The Coking Indexes were found to apply to residua in a universal manner, and the theoretical basis for the indexes has been established (Schabron et al. 2001a, 2001b, 2001c). For the first time, a few simple measurements indicates how close undesired coke formation is on the coke formation induction time line. The Coking Indexes can lead to new process controls that can improve refinery distillation efficiency by several percentage points. Petroleum residua consist of an ordered continuum of solvated polar materials usually referred to as asphaltenes dispersed in a lower polarity solvent phase held together by intermediate polarity materials usually referred to as resins. The Coking Indexes focus on the amount of these intermediate polarity species since coke formation begins when these are depleted. Currently the Coking Indexes are determined by either titration or solubility measurements which must be performed in a laboratory. In the current work, various spectral, microscopic, and thermal techniques possibly leading to on-line analysis were explored for measuring the Coking Indexes.

Energy efficient data centers  

SciTech Connect

Data Center facilities, prevalent in many industries and institutions are essential to California's economy. Energy intensive data centers are crucial to California's industries, and many other institutions (such as universities) in the state, and they play an important role in the constantly evolving communications industry. To better understand the impact of the energy requirements and energy efficiency improvement potential in these facilities, the California Energy Commission's PIER Industrial Program initiated this project with two primary focus areas: First, to characterize current data center electricity use; and secondly, to develop a research ''roadmap'' defining and prioritizing possible future public interest research and deployment efforts that would improve energy efficiency. Although there are many opinions concerning the energy intensity of data centers and the aggregate effect on California's electrical power systems, there is very little publicly available information. Through this project, actual energy consumption at its end use was measured in a number of data centers. This benchmark data was documented in case study reports, along with site-specific energy efficiency recommendations. Additionally, other data center energy benchmarks were obtained through synergistic projects, prior PG&E studies, and industry contacts. In total, energy benchmarks for sixteen data centers were obtained. For this project, a broad definition of ''data center'' was adopted which included internet hosting, corporate, institutional, governmental, educational and other miscellaneous data centers. Typically these facilities require specialized infrastructure to provide high quality power and cooling for IT equipment. All of these data center types were considered in the development of an estimate of the total power consumption in California. Finally, a research ''roadmap'' was developed through extensive participation with data center professionals, examination of case study findings, and participation in data center industry meetings and workshops. Industry partners enthusiastically provided valuable insight into current practice, and helped to identify areas where additional public interest research could lead to significant efficiency improvement. This helped to define and prioritize the research agenda. The interaction involved industry representatives with expertise in all aspects of data center facilities, including specialized facility infrastructure systems and computing equipment. In addition to the input obtained through industry workshops, LBNL's participation in a three-day, comprehensive design ''charrette'' hosted by the Rocky Mountain Institute (RMI) yielded a number of innovative ideas for future research.

Transformer Efficiency Assessment - Okinawa, Japan  

Science Conference Proceedings (OSTI)

The US Army Engineering & Support Center, Huntsville (USAESCH), and the US Marine Corps Base (MCB), Okinawa, Japan retained Idaho National Laboratory (INL) to conduct a Transformer Efficiency Assessment of “key” transformers located at multiple military bases in Okinawa, Japan. The purpose of this assessment is to support the Marine Corps Base, Okinawa in evaluating medium voltage distribution transformers for potential efficiency upgrades. The original scope of work included the MCB providing actual transformer nameplate data, manufacturer’s factory test sheets, electrical system data (kWh), demand data (kWd), power factor data, and electricity cost data. Unfortunately, the MCB’s actual data is not available and therefore making it necessary to de-scope the original assessment. Note: Any similar nameplate data, photos of similar transformer nameplates, and basic electrical details from one-line drawings (provided by MCB) are not a replacement for actual load loss test data. It is recommended that load measurements are performed on the high and low sides of transformers to better quantify actual load losses, demand data, and power factor data. We also recommend that actual data, when available, be inserted by MCB Okinawa where assumptions have been made and then the LCC analysis updated. This report covers a generalized assessment of modern U.S. transformers in a three level efficiency category, Low-Level efficiency, Medium-Level efficiency, and High-Level efficiency.

Efficiency of TTAC's ORTEC IDM  

Science Conference Proceedings (OSTI)

ORNL's Technical Testing and Analysis Center (TTAC) acquired a High Purity Germanium Detector (HPGe) from ORTEC - a variant called an Interchangeable Detection Module (IDM). This detector has excellent energy resolution as well as high intrinsic efficiency. The purpose of this report is to detail the determination of the efficiency curve of the IDM, so future measurements can quantify the (otherwise unknown) activity of sources. Without such a curve, the activity cannot be directly reported by use of the IDM alone - a separate device such as an ion chamber would be required. This builds upon the capability of TTAC. The method for determining the energy-dependent intrinsic efficiency is laid-out in this report. It's noteworthy that this basic technique can be applied to any spectroscopic radiation detector, independent of the specific type (e.g. NaI, CzT, ClYC).

Definition of Energy Efficiency  

U.S. Energy Information Administration (EIA) Indexed Site

Energy Users Energy Efficiency Page Energy Efficiency Definition Energy Users Energy Efficiency Page Energy Efficiency Definition Energy Efficiency: Definition Stairs) "Take the Stairs--Be More Energy Efficient" Person A interprets the sign as the "true" definition of energy efficiency. To Person A, the elevator is not being used. He is still getting to where he wants to go and using less energy in doing so. Person B considers the fact that she is not getting to where she is going with the same ease. She does not believe that she is being energy efficient, but instead she believes that she is "conserving energy" at a reduced level of service-she has to walk instead of ride. When it comes to trying to define "to be energy efficient" or "energy efficiency", there does not seem to be a single commonly-accepted definition of energy efficiency. Along the lines of Person B's thinking, it is generally thought that an increase in energy efficiency is when either energy inputs are reduced for a given level of service, or there are increased or enhanced services for a given amount of energy inputs.

PROGRESS IN ENERGY EFFICIENT BUILDINGS  

SciTech Connect

Recent accomplishments in buildings energy research by the diverse groups in the Energy Efficient Buildings Program at Lawrence Berkeley Laboratory (LBL) are summarized. We review technological progress in the areas of ventilation and indoor air quality, buildings energy performance, computer modeling, windows, and artificial lighting. The need for actual consumption data to track accurately the improving energy efficiency of buildings is being addressed by the Buildings Energy Data (BED) Group at LBL. We summarize results to date from our Building Energy Use Compilation and Analysis (BECA) studies, which include time trends in the energy consumption of new commercial and new residential buildings, the measured savings being attained by both commercial and residential retrofits, and the cost-effectiveness of buildings energy conservation measures. We also examine recent comparisons of predicted vs. actual energy usage/savings, and present the case for building energy use labels.

What's Energy Efficiency?  

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

What is energy efficiency? What is energy efficiency? Energy efficiency is "using less energy to provide the same service". There are other definitions, but this is a good operational one. The best way to understand this idea is through examples: When you replace a single pane window in your house with an energy-efficient one, the new window prevents heat from escaping in the winter, so you save energy by using your furnace or electric heater less while still staying comfortable. In the summer, efficient windows keep the heat out, so the air conditioner does not run as often and you save electricity. When you replace an appliance, such as a refrigerator or clothes washer, or office equipment, such as a computer or printer, with a more energy-efficient model, the new equipment provides the same service, but

Here, we examine the broader policy context for appliance standards and consumer benefits. Policy Context Appliance efficiency standards provide a minimum requirement for energy efficiency at the point of manufacture (or import). These standards seek to overcome market failures-including price distortions and transaction costs-that have historically given rise to a gap between observed and attainable product efficiencies. In this way, appliance standards complement information programs, utility DSM and other incentive programs,

How Far Energy Efficiency?  

E-Print Network (OSTI)

Analysts agree about the need for developing both new and cleaner energy resources. At the same time, some argue that energy efficiency can provide only a minimal role in meeting future energy needs. Hence, energy supply is encouraged while energy efficiency is supported only minimally. Analysts Douglas Lightfoot and Christopher Green suggest in a series of papers, for example, that there are practical limits that will constrain the rate of efficiency improvement to no more than about one percent per annum over the next 100 years. This paper explores the assumptions that underpin such “practical limits ” and concludes that efficiency gains perhaps could more than double the rate suggested by Lightfoot and Green. The question is not one of practical limits; rather, the issue is one of choosing to develop energy paths that allow greater system efficiencies to emerge.

We analyze ICA using semiparametric theories and propose a straightforward estimate based on the efficient score function by using B-spline approximations. The estimate is asymptotically efficient under moderate conditions and exhibits better performance than standard ICA methods in a variety of simulations.

Energy Efficiency Upgrades  

Science Conference Proceedings (OSTI)

The energy efficiency upgrades project at Hardin County General Hospital did not include research nor was it a demonstration project. The project enabled the hospital to replace outdated systems with modern efficient models. Hardin County General Hospital is a 501c3, nonprofit hospital and the sole community provider for Hardin and Pope Counties of Illinois. This project provided much needed equipment and facility upgrades that would not have been possible through locally generated funding. Task 1 was a reroofing of the hospital. The hospital architect designed the replacement to increase the energy efficiency of the hospital roof/ceiling structure. Task 2 was replacement and installation of a new more efficient CT scanner for the hospital. Included in the project was replacement of HVAC equipment for the entire radiological suite. Task 5 was a replacement and installation of a new higher capacity diesel-fueled emergency generator for the hospital replacing a 50+ year old gas-fired generator. Task 7 was the replacement of 50+ year-old walk-in cooler/freezer with a newer, energy efficient model. Task 8 was the replacement of 10+ year-old washing machines in the hospital laundry with higher capacity, energy efficient models. Task 9 was replacement of 50-year old single pane curtain window system with double-pane insulated windows. Additionally, insulation was added around ventilation systems and the curtain wall system.

Managing Energy Efficiency Improvement  

E-Print Network (OSTI)

In 1991, the World Business Council for Sustainable Development (WBCSD) introduced “Eco- Efficiency” as a management strategy to link financial and environmental performance to create more value with less ecological impact. Based on this strategy, CETAC-WEST (Canadian Environmental Technology Advancement Corporation - West), in mid-2000, introduced a practical approach to eco-efficiency to Western Canada's upstream oil and gas sector. The CETAC-WEST Eco-Efficiency Program, focused primarily on sour gas processing facilities, has developed methods and programs to identify opportunities for energy conservation and GHG reductions. The program outlined in this paper consists of four interrelated phases that are used to identify and track efficiency opportunities as well as promote the use of energy efficient methodologies and technologies. If, as program results suggest, 15% to 20% of the gas that is now consumed at by plant operations can be saved through efficiencies, it would save $500 to $700 million worth of gas for sale on the market. Although this small Pilot Program in the gas processing sector has surfaced major opportunities, there are significantly greater opportunities in other sectors with high GHG emissions intensity, such as sweet gas processing, conventional oil, heavy oil and oil sands. Capturing these opportunities will require a carefully considered strategy. This strategy should include, in addition to commitments for expanding the scope of the current Program, sustained leadership by industry champions and by governments - all aimed at changing the operating mode and improving the culture in the oil and gas industry.

Improving Gas Flooding Efficiency  

SciTech Connect

This study focuses on laboratory studies with related analytical and numerical models, as well as work with operators for field tests to enhance our understanding of and capabilities for more efficient enhanced oil recovery (EOR). Much of the work has been performed at reservoir conditions. This includes a bubble chamber and several core flood apparatus developed or modified to measure interfacial tension (IFT), critical micelle concentration (CMC), foam durability, surfactant sorption at reservoir conditions, and pressure and temperature effects on foam systems.Carbon dioxide and N{sub 2} systems have been considered, under both miscible and immiscible conditions. The injection of CO2 into brine-saturated sandstone and carbonate core results in brine saturation reduction in the range of 62 to 82% brine in the tests presented in this paper. In each test, over 90% of the reduction occurred with less than 0.5 PV of CO{sub 2} injected, with very little additional brine production after 0.5 PV of CO{sub 2} injected. Adsorption of all considered surfactant is a significant problem. Most of the effect is reversible, but the amount required for foaming is large in terms of volume and cost for all considered surfactants. Some foams increase resistance to the value beyond what is practical in the reservoir. Sandstone, limestone, and dolomite core samples were tested. Dissolution of reservoir rock and/or cement, especially carbonates, under acid conditions of CO2 injection is a potential problem in CO2 injection into geological formations. Another potential change in reservoir injectivity and productivity will be the precipitation of dissolved carbonates as the brine flows and pressure decreases. The results of this report provide methods for determining surfactant sorption and can be used to aid in the determination of surfactant requirements for reservoir use in a CO{sub 2}-foam flood for mobility control. It also provides data to be used to determine rock permeability changes during CO{sub 2} flooding due to saturation changes, dissolution, and precipitation.

Energy Efficiency Best Practice Guide©  

E-Print Network (OSTI)

'Setting the bar above mere mediocrity!' The goal of the Energy Efficiency (EE) Best Practice Guide is to help business units meet and exceed their energy efficiency targets through continuous improvement using seven key criteria. The objectives are threefold: -to provide an easy-to-use structure for measuring relative energy performance; -to identify key success and gap areas; and -to quantify seven key criteria. The seven criteria describe how they can help define best practices. The Guide is intended to compliment and enhance existing programs rather than 'layer on' additional work. The Guide was developed from experience and lessons learned from: • The Alliance to Save Energy's work on best practices; • Ontario Power Generation's Energy Efficiency Program from 1994 to 2000; and • A variety of sources including other companies that demonstrate EE best practices. The criteria are sufficiently generic to apply across business units and are applicable to most situations. The Guide must continually evolve from experience and new lessons learned. Feedback from business units, project experience, and from other industrial leaders will be encouraged and sought after. Your thoughts and comments are appreciated -please email Scott Rouse at: srouse@OntarioPowerGeneration.com

High Efficiency, Clean Combustion  

DOE Green Energy (OSTI)

Energy use in trucks has been increasing at a faster rate than that of automobiles within the U.S. transportation sector. According to the Energy Information Administration (EIA) Annual Energy Outlook (AEO), a 23% increase in fuel consumption for the U.S. heavy duty truck segment is expected between 2009 to 2020. The heavy duty vehicle oil consumption is projected to grow between 2009 and 2050 while light duty vehicle (LDV) fuel consumption will eventually experience a decrease. By 2050, the oil consumption rate by LDVs is anticipated to decrease below 2009 levels due to CAFE standards and biofuel use. In contrast, the heavy duty oil consumption rate is anticipated to double. The increasing trend in oil consumption for heavy trucks is linked to the vitality, security, and growth of the U.S. economy. An essential part of a stable and vibrant U.S. economy is a productive U.S. trucking industry. Studies have shown that the U.S. gross domestic product (GDP) is strongly correlated to freight transport. Over 90% of all U.S. freight tonnage is transported by diesel power and over 75% is transported by trucks. Given the vital role that the trucking industry plays in the economy, improving the efficiency of the transportation of goods was a central focus of the Cummins High Efficient Clean Combustion (HECC) program. In a commercial vehicle, the diesel engine remains the largest source of fuel efficiency loss, but remains the greatest opportunity for fuel efficiency improvements. In addition to reducing oil consumption and the dependency on foreign oil, this project will mitigate the impact on the environment by meeting US EPA 2010 emissions regulations. Innovation is a key element in sustaining a U.S. trucking industry that is competitive in global markets. Unlike passenger vehicles, the trucking industry cannot simply downsize the vehicle and still transport the freight with improved efficiency. The truck manufacturing and supporting industries are faced with numerous challenges to reduce oil consumption and greenhouse gases, meet stringent emissions regulations, provide customer value, and improve safety. The HECC program successfully reduced engine fuel consumption and greenhouse gases while providing greater customer valve. The US EPA 2010 emissions standard poses a significant challenge for developing clean diesel powertrains that meet the DoE Vehicle Technologies Multi-Year Program Plan (MYPP) for fuel efficiency improvement while remaining affordable. Along with exhaust emissions, an emphasis on heavy duty vehicle fuel efficiency is being driven by increased energy costs as well as the potential regulation of greenhouse gases. An important element of the success of meeting emissions while significantly improving efficiency is leveraging Cummins component technologies such as fuel injection equipment, aftertreatment, turbomahcinery, electronic controls, and combustion systems. Innovation in component technology coupled with system integration is enabling Cummins to move forward with the development of high efficiency clean diesel products with a long term goal of reaching a 55% peak brake thermal efficiency for the engine plus aftertreatment system. The first step in developing high efficiency clean products has been supported by the DoE co-sponsored HECC program. The objectives of the HECC program are: (1) To design and develop advanced diesel engine architectures capable of achieving US EPA 2010 emission regulations while improving the brake thermal efficiency by 10% compared to the baseline (a state of the art 2007 production diesel engine). (2) To design and develop components and subsystems (fuel systems, air handling, controls, etc) to enable construction and development of multi-cylinder engines. (3) To perform an assessment of the commercial viability of the newly developed engine technology. (4) To specify fuel properties conducive to improvements in emissions, reliability, and fuel efficiency for engines using high-efficiency clean combustion (HECC) technologies. To demonstrate the technology is compatible with B2

Green Building- Efficient Life Cycle  

E-Print Network (OSTI)

Energy saving does not just apply to traffic, production or agriculture. Buildings are also contributing to the climate change. The focus here is on the energy they use and on their CO2 emissions. Each year, Siemens invests more than two billion euros in the appropriate research and development. For customers, this means that Siemens is already providing them with energy efficient solutions that save resources and reduce emissions. Siemens Real Estate (SRE) has taken on the task of ensuring that Siemens AG will become 20 percent more energy efficient by 2011, and it has turned an efficiency program for existing real estate, which has been in existence since 2005, into an integrated green building initiative. This initiative comprises the components “Sustainable Building Design”, “Life Cycle Cost Analysis”, “Green Building Certification” and “Natural Resources Management”. These components are deliberately arranged around the life cycle of the real estate concerned. This allows a different emphasis to be placed on the different questions in each project phase and each phase of a building’s life and for them to be answered in a targeted manner. “Sustainable Building Design” comes into effect during the tasking and preliminary planning phase of a building project; and, by providing a specially developed sustainability manual, it helps with the definition of target values and the drawing up of efficiency strategies for the planning of the building. The manual epitomizes, and sets out clearly, the attitude of SRE to all building-specific sustainability matters. In addition, it is used in the offering of rewards for project competitions. As a result, through a selection of different energy-efficiency measures that have been roughly conceived beforehand, the primary energy consumption can already be restricted in the project definition phase. “Life Cycle Cost Analysis” comes into effect when the blueprint for buildings is being drawn up. Up to now, when components and systems were being chosen, the main focus was usually on the investment costs involved. By using a cost tool developed specifically to meet the needs of the company, SRE will in future be able to estimate the component-specific utilization costs – such as cleaning, maintenance, and the use of energy – at an early planning stage. “Green Building Certification” is used in building projects during the planning and implementation phase, and it thus ensures the quality of the new real estate over the long term. Siemens is implementing the Green Building Program of the European Commission in new building projects and renovation work in EU countries. In all other countries that are not taking part in the EU Green Building Program, SRE uses certification in accordance with LEED (Leadership in Energy and Environmental Design). In the LEED certification, a transparent and easy-to-use catalog of criteria is employed to make an assessment of the use of energy and other aspects of sustainability, such as the selection of the plot of land, the efficient use of water, the quality of air within buildings, and the selection of materials. This ensures that a neutral and independent assessment is made of all new building and large-scale renovation projects. The action program “Natural Resources Management” rounds off the range of measures in the area of existing real estate. The aim of the program is to identify and highlight all latent efficiency potential in existing buildings. This includes, for instance, modernizing the control equipment used for the heating and ventilation systems. This entails replacing electrical power units with more efficient models, and retrofitting fans and pumps with frequency converters. Sixty buildings have now been inspected, and savings of almost eight million Euros have been achieved. The average payback period is less than two years. One example of this is an old Siemens building from the 1970s at the Munich-Perlach site. Through energy optimization, it has been possible to cu

Assessing the efficiency of US electricity markets  

SciTech Connect

The recent California's energy crisis has raised doubts about the benefits of energy deregulation. While it is true that the California electricity market is in turmoil, other electricity markets like the Pennsylvania-New Jersey-Maryland (PJM) are doing fine. This paper assesses the mark of efficiency reached by the electricity markets in California, New York, and PJM. It also compares the degree of efficiency across markets (forward vs. real time) and across time. In terms of market efficiency no significant differences between the California and PJM electricity markets were discovered in the year of California's energy crisis (2000). This research suggests that differences in price behavior between these two markets during 2000 did not arise from differences in efficiency. According to our analysis and measure of efficiency, PJM and California electricity markets are more efficient than the New York market. Also, as these markets become more mature over time, their efficiency goes up. We also found evidence that multi-settlement scheduling system leads to higher efficiency.

Energy Efficiency Revitalization  

E-Print Network (OSTI)

To set the tone for my remarks I will start by saying- today, energy efficiency is a tough sell. In General Motors, our plant engineering people, faced with headcount deductions, budget cuts, and capital spending constraints are up to their “you know what” in alligators. It’s a real challenge to try to keep a manufacturing or assembly plant running under the present circumstances. In today’s atmosphere energy efficiency is just not a priority item demanding immediate action. Perhaps by this time you may have noticed I have not yet used the word conservation. This was a deliberate move. In General Motors, we are dropping the word conservation, which has developed a connotation of freezing in the dark and has been badly misunderstood over the years. We are opting for a more descriptive term- energy efficiency. As a matter of fact my title now is Manager-Energy Efficiency rather than Manager- Energy Conservation. We hope the use of the term energy efficiency will be more indicative of our endeavors and more in step with productivity and competitiveness. The business of saving money through increased energy efficiency needs all the help it can get. In fact, in our opinion, energy cost savings must become one of the before mentioned alligators. Or at least, a good sized burr in our collective saddles. Now don’t get me wrong. I am not advocating being a nasty old ogre in regard to energy efficiency. By the way, ogre is defined as a dreaded person or object. Acting as an ogre will get you absolutely nothing but a lot of criticism and rebuff. What I am advocating is doing everything possible to keep energy efficiency in the lineup of important things our people must do to properly fulfill their jobs. It almost has to become second nature to our business such as quality and safety. That’s a big order and how do you do it? I certainly don’t have all the answers to that question, but I will recount what we are attempting to do at GM in regard to energy efficiency. I do this with the hope that you may build on our experience and perhaps arrive at some new and original approach for our particular program.

Efficient Efficient Data Transfer Protocols for Big Data Brian Tierney ∗ , Ezra Kissel † , Martin Swany † , Eric Pouyoul ∗ ∗ Lawrence Berkeley National Laboratory, Berkeley, CA 94270 † School of Informatics and Computing, Indiana University, Bloomington, IN 47405 Abstract-Data set sizes are growing exponentially, so it is important to use data movement protocols that are the most efficient available. Most data movement tools today rely on TCP over sockets, which limits flows to around 20Gbps on today's hardware. RDMA over Converged Ethernet (RoCE) is a promising new technology for high-performance network data movement with minimal CPU impact over circuit-based infrastructures. We compare the performance of TCP, UDP, UDT, and RoCE over high latency 10Gbps and 40Gbps network paths, and show that RoCE-based data transfers can fill a 40Gbps path using much less CPU than other protocols.

Energy Efficiency and Commercial-Mortgage Valuation ?  

E-Print Network (OSTI)

Energy efficiency is key to the future of the U.S. economy, and commercial buildings are among the largest users of energy. However, existing loan underwriting practices provide no incentive for building owners to make their buildings more energy efficient. In this paper, we develop a commercial-mortgage valuation, or underwriting, strategy that accounts for the energy risk of individual office buildings, this energy risk being a function of both the relative energy efficiency of the building and the characteristics of its location. Our method extends standard underwriting practices, which account for the expected dynamics of interest rates and office building prices over time, by including the expected dynamics of the electricity and gas prices as well as quantity dynamics appropriate to the location of the building. This allows lenders to explicitly take into account the effect of energy use and various alternative efficiency measures when underwriting commercial mortgages.

Membranes Improve Insulation Efficiency  

E-Print Network (OSTI)

It has been determined from extensive tests involving test models and home attics that loose fill and fiber batt insulation does not function as expected by the industry. The reason for this deficiency is current test methods do not accurately predict the magnitude of air infiltration into fiber insulation as used in home attics, radiant heat infiltration into the insulation during summer, or radiant heat loss through the insulation during winter conditions. The use of (1) moisture permeable membranes over the insulation, and (2) layered membranes between fiber batts to form closed cells in the insulation both dramatically improve the efficiency of the fiber insulation. The efficiency of this insulation will be improved to an even greater degree if these membranes reflect radiant heat as well as reduce convection air currents. Extensive tests have also been conducted which show that if moisture permeable membranes are used over fiber insulation, the moisture content of the insulation will be reduced.

McKane Journal Energy Policy Volume 57 Start Page 318 Date Published 06/2013 Publisher Lawrence Berkeley National Laboratory Keywords industrial energy efficiency, industrial energy efficiency barriers, steam system efficiency Abstract Steam systems consume approximately one third of energy applied at U.S. industrial facilities. To reduce energy consumption, steam system energy assessments have been conducted on a wide range of industry types over the course of five years through the Energy Savings Assessment (ESA) program administered by the U.S. Department of Energy (U.S. DOE). ESA energy assessments result in energy efficiency measure recommendations that are given potential energy and energy cost savings and potential implementation cost values. Saving and cost metrics that measure the impact recommended measures will have at facilities, described as percentages of facility baseline energy and energy cost, are developed from ESA data and used in analyses. Developed savings and cost metrics are examined along with implementation and rejection rates of recommended steam system energy efficiency measures. Based on analyses, implementation of steam system energy efficiency measures is driven primarily by cost metrics: payback period and measure implementation cost as a percentage of facility baseline energy cost (implementation cost percentage). Stated reasons for rejecting recommended measures are primarily based upon economic concerns. Additionally, implementation rates of measures are not only functions of savings and cost metrics, but time as well.

Energy-efficient pipelines  

E-Print Network (OSTI)

We discuss the design of energy-efficient pipelines for asynchronous VLSI architectures. To maximize throughput in asynchronous pipelines it is often necessary to insert buffer stages, increasing the energy overhead. Instead of optimizing pipelines for minimum energy or maximum throughput, we consider a joint energy-time metric of the form ? ?,where?is the energy per operation and ? is the time per operation. We show that pipelines optimized for the ? ? energy-time metric may need fewer buffer stages and we give bounds when such stages can be removed. We present several common asynchronous pipeline structures and their energy-time optimized solutions. 1.

SciTech Connect

Most of us probably are not aware of all that's going on to improve the efficiency of energy usage in vehicles, residential climate control, manufacturing, and power management. The bulk of the energy consumption in the US during 2000 was apportioned as 34% for residential and commercial uses, 36.5% for industrial uses, and 26% for transportation. Automobiles in particular are the focus of intense energy conservation efforts. Only a surprising 25% of the fuel consumed by an automobile is converted to useful shalf work. The rest goes to the exhaust gases, coolant, friction and wear.

Method for assessing in-service motor efficiency and in-service motor/load efficiency  

DOE Patents (OSTI)

A method and apparatus for assessing the efficiency of an in-service motor. The operating characteristics of the in-service motor are remotely measured. The operating characteristics are then applied to an equivalent circuit for electrical motors. Finally the equivalent circuit is evaluated to determine the performance characteristics of said in-service motor. Based upon the evaluation an individual is able to determine the rotor speed, power output, efficiency, and toque of the in-service motor. Additionally, an individual is able to confirm the calculations by comparing measured values with values obtained as a result of the motor equivalent circuit evaluation.

The cost of steam has become a very real part of Product cost. U.S. Industry strives to become more fuel efficient, while increasing productivity. At the same time it must adhere to stringent emission regulations. The plant manager is faced with a bewildering number of avenues to explore to achieve efficiency improvements through the use of the widest conceivable array of products. These range from simple fuel additives to highly sophisticated Computer Programs. Each has merit. This paper recognizes that only a small percentage of plant managers have an in-depth understanding of combustion processes and presents simple yet factual measurements for the determination of boiler combustion, operating and maintenance efficiencies.

HIGH EFFICIENCY SYNGAS GENERATION  

DOE Green Energy (OSTI)

This project investigated an efficient and low cost method of auto-thermally reforming natural gas to hydrogen and carbon monoxide. Reforming is the highest cost step in producing products such as methanol and Fisher Tropsch liquids (i.e., gas to liquids); and reducing the cost of reforming is the key to reducing the cost of these products. Steam reforming is expensive because of the high cost of the high nickel alloy reforming tubes (i.e., indirectly fired reforming tubes). Conventional auto-thermal or Partial Oxidation (POX) reforming minimizes the size and cost of the reformers and provides a near optimum mixture of CO and hydrogen. However POX requires pure oxygen, which consumes power and significantly increases the cost to reforming. Our high efficiency process extracts oxygen from low-pressure air with novel oxygen sorbent and transfers the oxygen to a nickel-catalyzed reformer. The syngas is generated at process pressure (typically 20 to 40 bar) without nitrogen dilution and has a 1CO to 2H{sub 2} ratio that is near optimum for the subsequent production of Fisher-Tropsch liquid to liquids and other chemicals (i.e., Gas to Liquids, GTL). Our high process efficiency comes from the way we transfer the oxygen into the reformer. All of the components of the process, except for the oxygen sorbent, are commonly used in commercial practice. A process based on a longlived, regenerable, oxygen transfer sorbent could substantially reduce the cost of natural gas reforming to syngas. Lower cost syngas (CO + 2H{sub 2}) that is the feedstock for GTL would reduce the cost of GTL and for other commercial applications (e.g., methanol, other organic chemicals). The vast gas resources of Alaska's North Slope (ANS) offer more than 22 Tcf of gas and GTL production in this application alone, and could account for as much as 300,000 to 700,000 bpd for 20 to 30+ years. We developed a new sorbent, which is an essential part of the High Efficiency Oxygen Process (HOP). We tested the sorbent and observed that it has both a good oxygen capacity and operates as a highly effective reforming catalyst. We conducted a long duration tests of the sorbent (1,500 hours of continuous operation in the HOP cycle). Although the sorbent lost some oxygen capacity with cycling, the sorbent oxygen capacity stabilized after 1,000 hours and remained constant to the end of the test, 1,500 hour. The activity of the catalyst to reform methane to a hydrogen and carbon monoxide mixture was unchanged through the oxidation/reduction cycling. Our cost and performance analyses indicated a significant reduction in the cost of GTL production when using the HOP process integrated into a GTL plant.

Efficient Graffiti Image Retrieval  

Science Conference Proceedings (OSTI)

Research of graffiti character recognition and retrieval, as a branch of traditional optical character recognition (OCR), has started to gain attention in recent years. We have investigated the special challenge of the graffiti image retrieval problem and propose a series of novel techniques to overcome the challenges. The proposed bounding box framework locates the character components in the graffiti images to construct meaningful character strings and conduct image-wise and semantic-wise retrieval on the strings rather than the entire image. Using real world data provided by the law enforcement community to the Pacific Northwest National Laboratory, we show that the proposed framework outperforms the traditional image retrieval framework with better retrieval results and improved computational efficiency.

Energy Efficiency and Pollution Prevention: Industrial Efficiency Strategies  

E-Print Network (OSTI)

For many years, efforts to promote energy efficiency and pollution prevention (P2) traveled on separate, parallel paths. Most energy efficiency proponents considered only energy savings aspects of their projects and most P2 proponents did not include energy as a pollution source. More and more, however, the synergies between energy efficiency and P2 have become more apparent. Energy efficiency projects often have non-energy P2 benefits and P2 projects often save energy. Expanding projects to consider both energy efficiency and P2 enhances the financial viability of these types of projects because they allow businesses to minimize costs by using resources more efficiently. This paper discusses case studies of projects and companies that have successfully combined energy efficiency and pollution prevention technologies and strategies to enhance the environment, productivity and the bottom line.

As a result, in 2000 the PSB established Efficiency Vermont and a funding mechanism to support it. The funding mechanism, which varies by utility, is based on factors unique to each utility's service territory and is reviewed periodically and adjusted as necessary by the PSB.* It should be noted that Burlington Electric Department is not required to fund Efficiency Vermont;

High Efficiency Steam Electrolyzer  

SciTech Connect

A novel steam electrolyzer has been developed. In conventional electrolyzers, oxygen produced from electrolysis is usually released in the air stream. In their novel design, natural gas is used to replace air in order to reduce the chemical potential difference across the electrolyzer, thus minimizing the electrical consumption. The oxygen from the electrolysis is consumed in either a total oxidation or a partial oxidation reaction with natural gas. Experiments performed on single cells shown a voltage reduction as much as 1 V when compared to conventional electrolyzers. Using thin film materials and high performance cathode and anode, electrolysis could be done at temperatures as low as 700 C with electrolytic current as high as 1 A/cm{sup 2} at a voltage of 0.5 V only. The 700 C operating temperature is favorable to the total oxidation of natural gas while minimizing the need for steam that is otherwise necessary to avoid carbon deposition. A novel tubular electrolyzer stack has been developed. The system was designed to produce hydrogen at high pressures, taking advantage of the simplicity and high efficiency of the electrochemical compressors. A complete fabrication process was developed for making electrolyzer tubes with thin film coatings. A 100 W stack is being built.

Solar efficient structure  

Science Conference Proceedings (OSTI)

A solar efficient structure is disclosed which comprises a central chase positioned vertically within the structure and connected in fluid communication with a duct network positioned in thermal contact with the ground and with the attic of the structure. A fan is provided for circulating air through a perforated attic duct, through the various rooms of the structure, and through the duct network and the chase. In one embodiment, the fan is reversible so as to circulate the air in one direction, or in the other direction. When operating in the heating mode, the ground acts as a heat source to heat the air circulating through the duct network. Conversely, when operating in the cooling mode, the ground acts as a heat sink to cool the airflow circulating therethrough. A dehumidifier, and a heating or cooling means is provided for assisting in the conditioning of the circulating airflow. In one embodiment, the heating means comprises a greenhouse room which permits ultraviolet radiation to enter and heat the air contained therein, and a damper means for controlling the flow rate of the air circulating through the greenhouse room. The structure is fully insulated and includes a vent skin positioned about the exterior walls and the roof thereof. A method is disclosed for insulating the roof line with loose insulation.
