Energy Code Field Studies: Low-Rise Multifamily Air Leakage Testing
Document Type: Field Study, Reports and Studies | Publication Date:

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).
 

Residential Building Energy Efficiency Field Studies: Low-Rise Multifamily
Document Type: Field Study, Reports and Studies | Publication Date:

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.

Tennessee Residential Energy Code Field Study
Document Number: PNNL-31125 | Document Type: Field Study, State-specific | Publication Date:

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.

Oregon Residential Energy Code Field Study
Document Number: PNNL-30006 | Document Type: Field Study, Reports and Studies, State-specific | Publication Date:

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).

Virginia Residential Energy Code Field Study
Document Number: PNNL-29036 | Document Type: Field Study, Reports and Studies, State-specific | Publication Date:

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.
