Building 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. Washington State's new energy performance standards are an important start, but will not be enough to move Seattle's buildings to a clean energy future. OSE is currently drafting a policy framework for legislation to enact an emissions-based BPS for existing commercial and multifamily buildings 20,000 square feet and larger. OSE is conducting an inclusive stakeholder engagement process now through June 2022.
