Task Force discusses updates to fossil fuel free building codes by 2031

The SBCC WSEC-R TAG Meeting held on May 30, 2025, spotlighted critical discussions surrounding energy efficiency standards and fossil fuel-free building goals in Washington. A key focus was the upcoming 2031 mandate for constructing increasingly energy-efficient homes, with an ambitious target of achieving zero fossil fuel greenhouse gas emissions.

During the meeting, participants debated the implications of the current energy credit table, noting that some rows contained zeros or not applicable values, which could limit compliance options. Dwayne highlighted that this reduction could simplify the compliance process, suggesting that fewer efficiency measures might be needed to meet the new standards.

Deepa emphasized the importance of incremental energy efficiency gains leading up to the 2031 deadline, advocating for continuous improvements in building codes to align with the state's broader environmental goals. The discussion also touched on the role of the Pacific Northwest National Laboratory (PNNL) in modeling and adjusting credit values to ensure they reflect current energy performance standards.

As the meeting progressed, participants considered forming a work group to further refine these proposals, indicating a collaborative approach to addressing the challenges ahead. The dialogue underscored a commitment to evolving building codes that not only meet regulatory requirements but also contribute to a sustainable future.

The outcomes of this meeting could significantly influence Washington's energy landscape, as stakeholders work towards ambitious targets that aim to reduce reliance on fossil fuels and enhance energy efficiency in the coming years.
