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.
