WASHINGTON STATE CLEAN BUILDINGS PERFORMANCE STANDARD (CBPS)

WA Dept of Commerce

In 2019 the Clean Buildings bill was signed into law, expanded in 2022, and augmented in 2023. The objective is to lower costs and pollution from fossil fuel consumption in the state’s existing covered buildings, multifamily buildings, and campus district energy systems.

What Buildings are Affected by the CBPS?

Tier 1:

Tier 1 covered buildings (formerly known as covered commercial building) are buildings, where the sum of nonresidential, hotel, motel and dormitory floor area exceeds 50,000 gross square feet, excluding the parking garage area. Mandatory compliance and reporting for Tier 1 covered buildings begins June 2026 for buildings greater than 220,000 sq ft.

Tier 2:  

Tier 2 buildings are buildings where the sum of multifamily residential, nonresidential, hotel, motel and dormitory floor areas exceeds 20,000 gross square feet, but does not exceed 50,000 gross square feet, excluding the parking garage area. Tier 2 covered buildings also include multifamily residential buildings where floor areas are equal to or exceed 50,000 gross square feet, excluding the parking garage area.

What are the requirements?

Tier 1:

  • Benchmark by measuring and tracking energy use in a building over time.
  • Implement an operations and maintenance (O&M) program in accordance with the standard.
  • Create an energy management plan (EMP).
  • Tier 1 covered buildings must also meet an energy performance metric by either:
    • Meeting an energy use intensity target (EUIt). This metric represents a site-based energy use intensity (EUI) average for similar building types, and does not represent achieving “net-zero” or other green building certifications;
    • Utilizing the “investment criteria” pathway. This compliance route includes performing an energy audit and implementing all cost-effective efficiency measures (EEM).
