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

This book was released on 2014 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the lack of data on the United States' housing stock has been one of the primary barriers to market penetration of residential energy efficiency retrofits. Without knowledge of the homes and customers to reach, outreach has been untargeted and inefficient. As such, a study was performed to determine whether the potential for residential energy efficiency retrofit could be determined in the absence of utility data. The first phase of the research investigated the best pre-retrofit gas consumption metric to predict post-retrofit savings. Energy intensity (weather normalized total gas consumption per square foot) was chosen from four distinct metrics as the best corollary to energy savings. The second phase attempted to predict the pre-usage metric from phase one using only home characteristics and demographics, and the most predictive variables were determined. Data mining techniques were then explored to predict retrofit candidacy using energy intensity as a proxy. After showing that this was difficult to predict even when utility data was available, the progression to the third phase was reconsidered but explored. The models did not perform as expected for three reasons: 1) the marketing variables were not clean/accurate enough 2) the marketing variables did not explain enough of the variance in energy intensity and, 3) the connection between energy intensity and retrofit candidacy was not sufficiently well defined. While a definitive model of retrofit candidacy in the absence of utility data was not found, the research completed offers: 1) a mechanism by which to connect retrofit savings data to homes that have not yet undergone retrofit 2) an in-depth look at using publicly available variables to predict home energy consumption and, 3) a detailed examination of the connection between retrofit potential and raw gas utility data.

Download or read book Group Home Energy Efficiency Retrofit for 30 Energy Savings Washington D C written by and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy efficiency retrofits (EERs) face many challenges on the path to scalability. Limited budgets, cost effectiveness, risk factors, and accessibility impact the type and the extent of measures that can be implemented feasibly to achieve energy savings goals. Group home retrofits can face additional challenges than those in single family homes - such as reduced access (occupant-in-place restrictions) and lack of incentives for occupant behavioral change. This project studies the specification, implementation, and energy savings from an EER in a group home, with an energy savings goal of 30%. This short term test report chronicles the retrofit measures specified, their projected cost-effectiveness using building energy simulations, and the short term test results that were used to characterize pre-retrofit and post-retrofit conditions. Additionally, the final report for the project will include analysis of pre- and post-retrofit performance data on whole building energy use, and an assessment of the energy impact of occupant interface with the building (i.e., window operation). Ultimately, the study's results will be used to identify cost effective EER measures that can be implemented in group homes, given constraints that are characteristic of these buildings. Results will also point towards opportunities for future energy savings.

Book excerpt: Expanding on previous research by PARR, this study compares measure packages installed during 800 Illinois Home Performance with ENERGY STAR® (IHP) residential retrofits to those recommended as cost-optimal by Building Energy Optimization (BEopt) modeling software. In previous research, cost-optimal measure packages were identified for 15 Chicagoland single family housing archetypes, called housing groups. In the present study, 800 IHP homes are first matched to one of these 15 housing groups, and then the average measures being installed in each housing group are modeled using BEopt to estimate energy savings. For most housing groups, the differences between recommended and installed measure packages is substantial. By comparing actual IHP retrofit measures to BEopt-recommended cost-optimal measures, missed savings opportunities are identified in some housing groups; also, valuable information is obtained regarding housing groups where IHP achieves greater savings than BEopt-modeled, cost-optimal recommendations.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This report assesses the potential national benefits of retrofitting U.S. single-family homes with state-of-the-art GSHP systems at various penetration rates. The benefits considered include energy savings, reduced summer electrical peak demand, consumer utility bill savings, and reduced carbon dioxide (CO2) emissions. The assessment relies heavily on energy consumption and other data obtained from the Residential Energy Consumption Survey conducted by the U.S. Department of Energy s Energy Information Administration. It also considers relative differences in energy consumption between a state-of-the-art GSHP system and existing residential space-heating, space-cooling, and water-heating (SH SC WH) systems, which were determined with a well-established energy analysis program for residential SH SC WH systems. The impacts of various climate and geological conditions, as well as the efficiency and market share of existing residential SH SC WH systems, have been taken into account in the assessment.
