Document Number: DOE/EE-1972
Document Type: Analysis, Determination, Technical Support Document
The most recent edition, the 2018 IECC, was published in August 2017, triggering the DOE review and determination process. In response, DOE and Pacific Northwest National Laboratory (PNNL) conducted a preliminary analysis to determine energy savings for the 2018 IECC residential provisions relative to the previous edition--the 2015 IECC. This report documents the methodology used to conduct the analysis and summarizes the results and findings.
