Q2 2025 Codes, Standards and New Construction Newsletter

This quarter, the Northwest Energy Efficiency Alliance (NEEA) staff continued to champion the role of building codes and standards in helping to make homes and appliances more affordable for consumers. Drawing on recent data and analysis, the team recommended updates to building codes in Washington, Oregon, and the International Energy Code (IECC), which is the reference code for Idaho and Montana. Staff also supported code-related discussions in Idaho and Montana as those states consider next steps for their building codes. At the federal level, while the U.S. Department of Energy (U.S. DOE) proposed nearly two dozen changes to existing standards, NEEA submitted comments underscoring the consumer benefits of each standard—benefits supported by both U.S. DOE’s analysis and NEEA’s own data.

To support the construction industry ahead of the busy summer season, NEEA also delivered successful training sessions for builders and code officials in three of the four Northwest states (ID, MT, WA). These trainings remain a cornerstone of NEEA’s efforts to ensure successful and effective code implementation across the region.
