In the past two years, the Northwest Energy Efficiency Alliance (NEEA) has collaborated with the U.S. Department of Energy and Pacific Northwest National Laboratory to complete residential energy code field studies in all four states in the northwest region, including Idaho, Montana, Oregon and Washington. These research studies and the resulting empirical data provide market-based evidence and understanding of how the various state codes affect new home construction and related energy performance. The speakers, key members of the field teams, will share their experiences, observations and lessons learned from their time onsite and interactions with builders and local building departments. The variation of code structures among these four states also provide insight—through tested experiences—on how DOE’s field study methodology can be tailored to state codes as well as for the upcoming 2021 IECC.
This was the eleventh event in the 2020 Building Energy Code Webinar Series.
