These analyses evaluate the cost-effectiveness of the prescriptive path of the 2018 edition of the International Energy Conservation Code (IECC), relative to the 2015 IECC with amendments for all 50 states and the District of Columbia. The analysis covers one- and two-family dwelling units, townhouses, and low-rise multifamily residential buildings covered by the residential provisions of the 2018 IECC.

The most recent edition, the 2021 IECC, was published on January 29, 2021, triggering the DOE review and determination process2. DOE and Pacific Northwest National Laboratory (PNNL) conducted a technical analysis to determine energy savings for the 2021 IECC residential provisions relative to the previous edition, the 2018 IECC (ICC 2017). This report documents the methodology used to conduct the analysis and summarizes the results.

To meet the statutory requirement, DOE conducted an analysis to quantify the expected energy savings associated with Standard 90.1-2019. This report documents the methodology used to conduct the analysis. Based on the analysis, DOE has preliminarily determined that the 2019 edition of the ANSI/ASHRAE/IES Standard 90.1 would improve overall energy efficiency in buildings subject to the code (compared to the 2016 edition of Standard 90.1).

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.

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).

This report summarizes technical analysis conducted by Pacific Northwest National Laboratory (PNNL), assessing expected end-use energy consumption in commercial buildings, based on recent editions of the model energy code for the commercial sector, ANSI/ASHRAE/IES Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings. An accompanying spreadsheet is available containing detailed end use data results from the Progress Indicator analysis.

This spreadsheet contains detailed end use data results from the Progress Indicator analysis of ASHRAE Standard 90.1-2016 conducted by PNNL.

The BC3 data, as referenced in the methodology for conducting national and custom state-level analyses, was originally available as a web-based database, but has now been archived and made available as a spreadsheet. This spreadsheet represents the complete contents of the BC3 database.
