Commercial building owners throughout Washington State will be required to reduce greenhouse gas emissions in the face of the Clean Buildings Performance Standard (CBPS) and subsequent expansion bill of 2022. The bill requires owners of existing buildings to conform to state-mandated specific energy performance targets that must be met by designated deadlines. The goal is to enhance building efficiency, lower operational costs, and contribute to the state’s broader environmental objectives. 

For building owners and facility managers, maintaining CBPS compliance and reporting deadlines can mean avoiding fines, earning incentives, reducing operating costs and downtime, and supporting long-term sustainability and building performance goals. 



Who does the WA CBPS impact and what is the compliance reporting schedule?

Owners of existing buildings that are 20,000 sq. ft. and larger need to benchmark their energy consumption, create an energy management plan (EMP), and an operations and maintenance (O&M) plan. 

Buildings are categorized into two main categories referred to as Tier 1 and Tier 2.

Tier 1 and Tier 2 building compliance reporting deadlines

  • Tier 1 building compliance deadlines are as soon as June 1, 2026, for buildings with more than 220,000 square feet. Campuses can get an exemption from their Tier 1 target if the university implements a decarbonization plan. 
  • Tier 2 buildings must report on benchmarking, energy management plans, and operations and maintenance programs by July 1, 2027.

CBPS Early Adopter incentives

The same Clean Buildings Law that requires all covered commercial buildings in Washington to comply with CBPS created an Early Adopter Incentive (EAI) Program that provides incentives to building owners who demonstrate early compliance.

Reference the Tier 1 EAI Guidebook and Tier 2 EAI Guidebook to determine if your building may be eligible to receive incentive funding.

Penalties for failing to comply

Tier I and II buildings that fail to comply with the mandated reporting schedule will be subject to fines. The Tier I penalty is up to $5,000 + $1.50/sq. ft. at each compliance cycle. The Tier II penalty is $0.30/sq. ft. at each compliance cycle.

How do I make sure my building(s) meets the WA CBPS requirements?

WA CBPS Compliance Process

Navigating the new limits introduced as part of CBPS can be overwhelming and stressful for building owners. Each journey toward compliance may look different but rest assured, the right collaborator will meet you at any point. 

The CBPS mandate requires 6 basic steps:

  • Conduct a comprehensive assessment of the building’s current energy performance, identifying areas of inefficiency.
  • Create a detailed energy management plan that outlines strategies for reducing energy consumption and helping to improve efficiency. 
  • Develop an O&M program to ensure ongoing maintenance and operational practices align with energy-saving goals and compliance.

*Often must be completed 12 months before reporting.

  • Implement the identified energy efficiency projects and upgrades, while meeting related incentive program requirements.
  • If the EUI target is met, proceed to Step 6.
  •  Complete the project by confirmingall upgrades and changes are fully operational.
  • Conduct measurement and verification to assess the effectiveness of the improvements, helping to support expected energy performance outcomes and comply with WA CBPS.
  • Document the results and make any necessary adjustments to maintain compliance. 
  • Repeat Step 4 every 5 years. 
  • Install recommended energy efficiency improvements and controls upgrades to help reduce EUI or GHGs. 
  • Measures may include HVAC retrofits, controls optimization, heat pump installations, or envelope improvements.  
  • Demonstrate ongoing compliance through annual reporting and data tracking. 
  • Maintain performance to avoid penalties or loss of incentive eligibility. 

How does Seattle Building Emissions Performance Standard (BEPS) differ from CBPS compliance?

In December 2023, Seattle signed the Building Emissions Performance Standard (BEPS) policy that requires existing nonresidential and multifamily buildings greater than 20,000 sq. ft. to comply with emissions reduction requirements. This is consistent with buildings required to comply with WA CBPS.

Seattle BEPS compliments CBPS with energy efficiency, however BEPS specifically targets building emission reduction – aiming for a 27% reduction in Seattle building emissions by 2050. The first compliance interval takes place from 2027-2030, in which owners will have to verify their current energy and emissions performance, and develop plans to start meeting decarbonization targets. 

Reference the Seattle Office of Sustainability & Environment Guide to Seattle BEPS for additional information on performance targets and penalties for noncompliance. 

Trane® is ready to collaborate with you and help you navigate a journey towards CBPS compliance.

Where do I begin?

Understanding the specific requirements of the WA standards is crucial. Therefore, reviewing the guidelines and setting clear, achievable goals is essential. Engaging with experienced energy consultants can help provide valuable insights and recommendations tailored to your building’s needs.
