Attention Tier 1 Building Owners: Don't wait until 2027. Compliance requires 12 months of verified data prior to filing. Your deadline to start your Energy Management Plan is June 1, 2026. Let’s get started!

Washington Clean Building Performance Standard

Don’t Just Comply. Capitalize.

WA CBPS Compliance Requirements by Tier

The Washington State Clean Buildings Performance Standard (CBPS) requires owners to actively manage energy performance. It applies to both Tier 1 (Large) and Tier 2 (Medium) buildings, but the obligations differ significantly.

Currently, Tier 1 buildings are approaching major compliance deadlines, while the law has expanded to cover smaller commercial and all multifamily buildings over 20,000 square feet (Tier 2).

⚠ More Than Just Reporting

Unlike simple benchmarking laws, Washington requires operational excellence. Every covered building must implement an Energy Management Plan (EMP) and an Operations & Maintenance (O&M) Program.

Tier 1 Buildings

Performance Mandate

Commercial Buildings > 50,000 SF

Required Actions
  • Benchmark Energy Consumption
  • Implement O&M Program
  • Energy Management Plan
  • Meet Energy Target (EUIt)
If Target Is Missed
Investment Criteria Required.
You must perform a Level 2 Energy Audit and implement all cost-effective retrofits to achieve compliance.
Tier 2 Buildings

Reporting & Management

20,000 - 50,000 SF & Multifamily

Required Actions
  • Benchmark Energy Consumption
  • Implement O&M Program
  • Energy Management Plan
  • Meet Energy Target (EUIt)
If Target Is Missed
No Penalty for Performance.
Compliance is based on reporting and management plans. You are not required to retrofit if you miss the target.
Early Adopter Incentive
Base Rate (Commercial) $0.30/sf
Enhanced (Multifamily) $0.75/sf

WA Clean Buildings FAQ

Common questions on CBPS costs, timelines, and requirements.

We believe in fair, transparent pricing. Unlike competitors who charge massive flat fees, we quote based on expected hourly effort so you only pay for the work your building actually needs.

For a typical commercial building, developing a fully compliant Energy Management Plan (EMP) and O&M Program typically ranges from $4,000 – $8,000. For a Tier 2 building, the costs are often more than fully offset by available incentives, leaving you with funds in your pocket.

If your building requires an energy audit, we provide competitive proposals based on actual site conditions. Typically, this ranges from $0.25 - $0.50/sf for an ASHRAE Level 2 audit.
Timelines vary by building size, but we recommend starting early to avoid bottlenecks as deadlines approach.
  • EMP & O&M Development: Can be completed in as fast as 2 months.
  • Energy Audit: Typically takes 3 months to complete site visits, analysis, and reporting.
  • State Review: Once submitted, the CBPS review process often takes 4-8 weeks or longer.
The EMP is a mandatory document required by Section 5 of the standard. It is not just a report; it is a "living document" that defines how your building tracks energy, who is responsible for maintenance, and how staff are trained.

Crucial Detail: This plan must be created and implemented 12 months before your reporting date. We develop this custom plan for you to ensure it meets all state requirements.
It is not enough to simply repair things when they break. The standard requires a documented Operations & Maintenance (O&M) Program that follows ASHRAE Standard 100 (Section 6).

This includes creating maintenance logs for HVAC, lighting, and domestic hot water systems, and verifying they are operating efficiently.

How we help: We don't just write the plan; we can provide the required staff training and annual oversight to ensure your team is filling out the logs correctly and staying compliant year after year.
Yes. The State has funded an Early Adopter Incentive program to encourage early compliance.

  • Base Rate: $0.30 per sq. ft.
  • Enhanced Rate: $0.75 per sq. ft. (Multifamily/High-Performance)

These funds are limited and first-come, first-served. We can help you assess your eligibility and apply before the funds run out.
You will not necessarily be fined. If you cannot meet the EUIt target operationally, you must follow the "Investment Criteria" pathway.

This involves performing an ASHRAE Level 2 Energy Audit to identify energy-saving measures. If the measures are not cost-effective (do not pay for themselves over the life of the equipment), you may be exempt from implementing them while still achieving compliance.
