Turn Compliance into Value: What Washington Property Owners Should Know about the Clean Buildings Performance Standard

For owners of commercial buildings 20,000 square feet and larger in Washington State, the Clean Buildings Performance Standard (CBPS) represents more than a regulatory requirement—it is a strategic opportunity. By improving energy performance, owners can increase asset value, lower operating costs, and reduce long-term risk in a market that increasingly prioritizes sustainability and operational efficiency. Compliance is not simply about filing reports; it involves benchmarking, planning, performance evaluation, and targeted investment in measures that create lasting financial and operational benefits.

 Which Buildings Must Comply?

The CBPS applies to existing commercial and multifamily buildings 20,000 sf and above, categorized into two compliance tiers:

• Tier 1 covered buildings reporting schedule:

• June 1, 2026 – More than 220,000 sq. ft.
• June 1, 2027 – More than 90,000 sq. ft. but less than 220,001 sq. ft.
• June 1, 2028 – More than 50,000 sq. ft. but less than 90,001 sq. ft.

• Tier 2 covered buildings reporting schedule:
  • July 1, 2027: More than 20,000 sq. ft. but less than 50,001 sq. ft. and all multifamily residential buildings more than 20,000 sq. ft.

Owners of any property within these size ranges should begin preparing now, as compliance planning and energy improvements often require multi-year timelines.

Key Compliance Requirements of Clean Buildings Performance Standard

To meet the CBPS, building owners must complete several core actions designed to improve energy efficiency and maintain performance over time:

1. Benchmark Energy Use
   Buildings must track and report annual energy consumption using tools such as ENERGY STAR Portfolio Manager, establishing a performance baseline and enabling year-over-year evaluation.
2. Develop an Energy Management Plan (EMP)
   An EMP outlines a building’s long-term energy strategy, including performance goals, operational policies, and roles/responsibilities for ongoing implementation.
3. Implement an Operations & Maintenance (O&M) Program
   Proper O&M ensures that major building systems—from HVAC to lighting to controls—perform efficiently and consistently, preventing energy waste and increasing equipment longevity.
   • Tier 1 buildings must implement O&M Programs 12 months prior to the mandatory compliance date
4. Meet Energy Use Intensity (EUI) Targets or Follow an Investment Pathway (Tier 1 Only)
   Tier 1 buildings must either:
   • Achieve a site-specific EUI target, or
   • Pursue compliance through an Investment Criteria pathway, consisting of an ASHRAE Level 2 energy audit, life-cycle cost analysis, and implement all cost-effective measures as defined by state criteria. This allows owners some flexibility in meeting compliance requirements.
5. Build Your Team

CBPS requires a Qualified Person to oversee and verify several components (EMP, O&M, EUIt calculations, Investment Criteria). Qualifications include Proefssional Eengineers, Certified Energy Managers, Certified Commissioning Professionals, etc. A Qualified Person must prepare and/or sign off on:

• The Energy Management Plan
• O&M Program
• EUIt target analysis
• Investment Criteria documentation
• Performance reporting

Deadlines and Reporting Cycle of Clean Buildings Performance Standard

After initial compliance, buildings must re-report every five years to verify sustained performance, showing 12 consecutive months of compliant energy data within the two-year window prior to the deadline. Missing deadlines can result in financial penalties, which makes proactive preparation essential.

Penalties of WA CBPS

Noncompliance with Washington’s Clean Buildings Performance Standard can result in significant fines:

Tier 1 Buildings

• Up to $5,000 for missing required documentation (EMP, O&M, EUIt analysis, Investment Criteria, or reporting).
• Additional penalties up to $1.00–$1.50 per square foot for failing to meet required energy performance targets.
• EMP and O&M must be implemented 12 months before the compliance deadline; failure to do so can trigger fines.

Tier 2 Buildings

• Penalties up to $0.30 per square foot for missing or late EMP/O&M documentation.
• Benchmarking failures may result in additional fines.

 Ongoing Enforcement

Penalties may accrue monthly until compliance is achieved, and Commerce may require corrective action plans for persistent violations.

Support, Incentives, and Technical Assistance

Washington State offers technical support programs, training resources, and incentive funding, particularly for early compliance or energy upgrades. These opportunities can significantly offset audit, planning, or capital improvement costs.

Turning Compliance Into Value

Approached strategically, CBPS compliance can:

• Reduce utility costs through lower energy consumption
• Improve tenant comfort and retention
• Increase asset marketability and valuation
• Extend the life of building systems
• Prepare properties for future carbon-reduction policies and market expectations
