Building Emissions Performance Standards

Building performance standards (BPS) are energy or emissions targets that existing buildings must meet over time to improve energy efficiency and reduce climate impacts. While Washington State's energy performance standards are an important start, they will not be enough to meet Seattle's climate goals and a move to a cleaner energy future. With extensive stakeholder engagement in 2022 and on-going development in 2023, OSE is drafting legislation to enact a Building Emissions Performance Standard (BEPS) policy for existing commercial and multifamily buildings larger than 20,000 square feet. Seattle's BEPS policy is projected to reduce building emissions 27% by 2050, making it the most impactful climate action Seattle can take now.
