Described separately from the U.S. DOE Multifamily Residential Energy Efficiency Field Study, this report is a simultaneous study of building air tightness occurred using several of the main study buildings and additional sites that met the building type criteria. Overall, 26 sites were evaluated this way using semi-automated testing equipment (blower doors).
Final report of the U.S. DOE Multifamily Residential Energy Efficiency Field Study to validate the impact of building energy codes in low-rise multifamily buildings and identify opportunities for increased energy that can be addressed through workforce education & training programs. Results include both characteristics summaries (by state) and an analysis of the opportunities associated with increased code compliance on building energy use in the different climate zones. As well, the process of collecting and processing building data so that these estimates can be prepared is described in detail, with the intent that others could employ this process in future studies. This report also includes a market research component that describes interviews with key actors in the multifamily sector (building designers, developers, and builders) that focuses on various aspects of the code, including specific code details relevant to code education and training, and overall energy performance.

Presentation slides from the 2019 National Energy Codes Conference that provided an overview of the U.S. Department of Energy Building Energy Codes residential field study Phase III data collection and findings.
A research project in the state of Tennessee identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code. The study was initiated in September 2017 and continued through July 2018. Analysis of the data has led to a better understanding of the energy features present in homes and indicates over $2.5 million in potential annual savings to Tennessee homeowners that could result from increased code compliance.
A research project in the state of Oregon identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code. The study was initiated in November 2019; data collection began in November 2019 and continued through February 2020. Analysis of the data has led to a better understanding of the energy features present in homes and identified over $600,000 in potential annual savings to Oregon homeowners that could result from increased compliance with the 2017 Oregon Residential Specialty Code (2017 ORSC).
A research project in the Commonwealth of Virginia identified opportunities to reduce homeowner utility bills in residential single-family new construction by increasing compliance with the state energy code. The study was initiated in August 2017 and continued through May 2018. During this period, research teams visited 138 homes during various stages of construction, resulting in a substantial data set based on observations made directly in the field.
This is the data collected for states using DOE's Residential Field Study Methodology, but not part of DOE's Residential Field Study. Data is currently available for ID, IL, MO, MT, NE, VA, and WV but additional data will be added as other states use the methodology.
This guide provides information for anyone dealing with a lighting energy code or standard. It provides background and development information to help readers understand the basis for requirements and their intent. The guide also provides detailed explanations of the major types of requirements such that users can more effectively design to meet compliance while applying the most flexibility possible.
This guide provides an aid that will make it easier to apply the heating, ventilation, and air conditioning (HVAC) control requirements found in building energy codes and addresses requirements defined by 2009 and 2012 editions of the International Energy Conservation Code (IECC) and ASHRAE Standard 90.1-2007 and ASHRAE Standard 90.1-2010.
This guide includes practical plan review and inspection resources, including the U.S. Department of Energy Building Energy Codes Program's REScheck™ and COMcheck™ quick reference guides, case studies, and sample inspection checklists; as well as excerpts from International Code Council's commentaries, workbooks, and code companion materials.
This collection also includes many other helpful items and points to further resources available on the web. Residential and commercial building officials can easily add state and local guidance in order to use this binder as a one-stop resource to support compliance in the field.
This guide is a resource for understanding the air leakage requirements in the 2012 IECC and suggestions on how these measures can be met. It also provides information from Building America’s Air Sealing Guide, best Practices and case studies on homes that are currently meeting the provisions. The 2012 IECC and a few International Residential Code requirements are referenced throughout the guide.
The Nebraska Energy Office (NEO) commissioned Britt/Makela Group, Inc. (BMG) to assess compliance with the commercial provisions of the 2009 International Energy Conservation Code (IECC). The goals of the project were to:
- Assess compliance rates for projects that represented typical commercial construction in Nebraska
- Collect information on energy code compliance issues that could be used to establish a framework for future energy code implementation programs in the state.
This report provides the results and methodologies for the 2010-2011 Iowa Energy Code Pilot Study that was conducted by the Iowa Department of Public Safety, division of State Fire Marshal, State Building Code Bureau. This study was funded by the U.S. Department of Energy with support from Pacific Northwest National Laboratories – Building Energy Codes Project and the Midwest Energy Efficiency Alliance (MEEA). Preliminary work on the study began in May of 2010. A contract with MEEA was signed in October 2010 with work commencing on the study in January 2011. The primary goal of the study was to determine the rate of compliance with the 2009 International Energy Conservation Code throughout the state of Iowa. Secondary goals of the study were to determine average energy code inspection durations, provide training to local code officials and builders participating in the study, and to determine areas of improvement.
The goals of this study were threefold: 1) Provide feedback to the BECP on the implementation of the BECP protocol 2) Develop a preliminary pattern/range of the existing compliance rates of newly constructed residential dwellings and commercial buildings based on jurisdictions in Illinois that have adopted the building energy codes and 3) Identify areas where home performance and codes training and education activities could be improved or refocused. Measurements of a small sample set (10) of commercial buildings were also taken. Due to the insignificance sample size, a commercial compliance rate is not reported here.
Project Goal: Assess and record energy code compliance of buildings currently under construction, following the U.S. Department of Energy (DOE) processes, in compliance with the American Recovery and Reinvestment Act of 2009 (ARRA), and identify procedural changes in code enforcement and training needed to improve compliance rates.
This study was conducted to estimate as-built energy use characteristics for homes that were not part of the Energy Efficiency Fund New Construction Program (RNC) as a baseline for the RNC Program. Resulting information will be applied to estimation of the net effects of the RNC Program on efficiency improvements. Additionally, these results are used to establish preliminary estimates of User Defined Reference Home (UDRH) inputs to be used as baseline characteristics against which construction within the RNC Program can be compared. Findings are based on the results of on-site inspections, including Home Energy Rating System (HERS) ratings, of 69 homes that were not part of the RNC program, were completed from November 2009 through July 2011, and whose owners agreed to have their home inspected.
Summary of the findings of the 2003 Residential New Construction Baseline Study conducted by Itron, Inc. under Pacific Gas & Electric (PG&E) management.1 KEMA-Xenergy conducted the on-site surveys. The RNC baseline study investigates energy efficiency in newly constructed single family homes throughout California. The study’s primary purpose is to provide information to residential new construction (RNC) program managers across the state, thereby allowing them to assess and address the effect of recent energy code changes on these programs.
From August 1997 to September 1999, one hundred new Arkansas homes were evaluated in two areas in the state where there was significant building activity in order to determine the energy performance of current building practices. One of the positive findings was that homes are now being built significantly tighter than a few years ago. Homes built in the early to in.id 1990's were experiencing an average of 0.5 natural air changes per hour (NACH), an acceptable level considered normal for new construction Only 24 homes in this evaluation had leakage rates exceeding 0.4 NACH; the majority of homes (58 percent) had leakage rates of 0.35 and under.
This report explains the methodology used to develop version 4.6.5 of the REScheck software in order to support compliance determination for IECC editions 2009, 2012, 2015, and 2018.
