Methodology for Evaluating Cost-Effectiveness of Residential Energy Code Changes
Document Number: PNNL-21294 Rev 1 | Document Type: Analysis, Cost-effectiveness | Publication Date:

DOE supports the development of the International Code Council’s (ICC) International Energy Conservation Code (IECC), the national model code adopted by or forming the basis of residential energy codes promulgated by a majority of U.S. states, as well as other voluntary building energy codes. DOE performs a cost-effectiveness analysis of proposed modifications to the codes as part of that support and also performs an analysis of cost-effectiveness of new code versions.1 This document represents the methodology DOE uses in performing such analyses.

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.
