Washington Clean Building Performance
Don’t Just Comply. Capitalize.
The State of Washington's Clean Buildings Performance Standard (CBPS) requires owners of large and medium-sized buildings to meet specific energy performance targets, and report the results to the state. This law is a key part of Washington's plan to reduce energy consumption and achieve its climate goals.
Currently, the largest commercial buildings (Tier 1) are approaching their first major compliance deadlines. The law is also expanding to cover smaller commercial and all multifamily buildings over 20,000 square feet (Tier 2).
Current Deadlines
The first compliance deadline for the largest commercial buildings, those over 220,000 square feet, is June 1, 2026. Deadlines for other Tier 1 buildings are staggered in 2027 and 2028.
For Tier 2 buildings (commercial and multifamily 20,001 - 50,000 sq. ft.), the compliance and reporting deadline is July 1, 2027.
Unlike simple benchmarking laws, Washington's standard requires buildings to meet specific Energy Use Intensity targets (EUIt). Buildings that don't meet their target must follow an "Investment Criteria" pathway, which involves energy audits and implementing cost-effective retrofits. This makes strategic planning your immediate, top priority to ensure compliance and avoid significant penalties.
