    • Tier 1 reporting schedule

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

    The Clean Buildings Performance Standard is mandatory for Tier 1 covered buildings located in the state of Washington. A Tier 1 covered building is a building 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.

    • Federal buildings and buildings owned by federally recognized tribes are not required to comply with the standard.
    • For Tier 2 covered buildings requirements, see the Tier 2 compliance webpage.

    Tier 1 compliance requirements

    • 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 meet an energy performance metric by either:
      1. 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;
      2. Utilizing the “investment criteria” pathway. This compliance route includes performing an energy audit and implementing all cost-effective efficiency measures (EEM).

    If the building meets at least one of the exemption criteria listed in RCW 19.27A.210(7)(c) (Section Z4.1 of the standard), building owners can apply for compliance through exemption up to three years prior to their scheduled mandatory compliance date.

    • Tier 1 buildings over 220,000 sq. ft. can apply for an exemption beginning on June 1, 2023.
    • Tier 1 buildings over 90,000 sq. ft. can apply for an exemption beginning on June 1, 2024.
    • Tier 1 buildings over 50,000 square feet can apply for exemption beginning on June 1, 2025.

    Applications for exemption shall be submitted to Commerce no later than 180 days prior to the mandatory compliance date. Aggregate gross floor area with nonexempt space greater than 20,000 square feet may be required to comply with Tier 2 covered building requirements.

    Approved certificates of exemption are only valid for the compliance review cycle for which they were applied. Within six months before the compliance date, building owners who have received exemption approval must certify that the building still meets the eligibility qualifications for the exemption and that there have been no material changes to qualifying conditions. Commerce will provide a one-page declaration for exempted building owners to sign.

    A list of acceptable exemption application supporting documentation can be found in:

    The application for exemptions can be found through the Clean Buildings Portal. See the CBPS Compliance Portal page for more information on how to access the Portal.

    This is a process-oriented standard with long lead times to help keep compliance costs down. It is most cost-effective to start the compliance process as early as possible.

    The Clean Buildings Portal is where you will submit compliance documentation and can apply for the Early Adopter Incentive Program. Building owners and authorized representatives may create a profile in the state’s Clean Building Portal. See the CBPS Compliance Portal page for more information on how to access the Portal.

    • Establish your building performance metric by benchmarking the building.
    • Create an account with the Energy Star Portfolio Manager (ESPM).
    • Contact your utility provider(s) to integrate your building into ESPM. Understand your utility providers’ role in compliance.
      • Utilities are required to provide energy consumption data to building owners upon request. Large utilities (greater than 25,000 customers) are required to provide this data using ESPM’s automated upload protocol. Smaller utilities are to provide the data to building owners in an Excel document, meeting Energy Star Portfolio Manager specifications (see RCW 19.27a.170).

    Benchmarking will help to determine which compliance path to pursue:

    1. EUIt path: Meeting an energy use intensity target (EUIt). This metric represents a site-based EUI average for similar building types, and does not represent achieving “net-zero” or other green building certifications;
      • To report compliance using the EUIt compliance path, establish the weather normalized energy use intensity (WNEUI) for each building in ESPM. Within the Portal, create the energy use intensity target (EUIt) for the building in accordance with Annex Z, Section Z6.2. For assistance on how to determine your building’s EUIt, refer to the guidance document How to Determine Energy Use Intensity Target (EUIt) and within the standard Table 7-2a Building Activity Site Energy Targets and Table 7-4 Building Activity Type Definitions Table.
    2. Investment Criteria: Utilizing the “investment criteria” pathway, with or without a measured energy use intensity (EUI). This compliance route includes performing an energy audit and implementing all cost-effective efficiency measures.
      • Buildings unable to develop an energy use intensity target (EUIt) cannot use the EUIt compliance path. Instead, they shall use the Investment Criteria compliance path, pursue compliance in accordance with the investment criteria performance metric, and are not required to create an ESPM account.

    Develop and implement the Energy Management Plan (EMP) and associated Operations and Maintenance Program (O&M) for each building as outlined in Sections 5 and 6 of the Clean Building Performance Standard. This step can happen concurrently with benchmarking.

    The EMP and O&M program are mandatory requirements for all covered buildings. Implementation of these requirements can begin at any time. The O&M program requirements must be implemented 12 months prior to the mandatory compliance date. There are no required templates. A current EMP and O&M program, which are in compliance with the Clean Building Performance Standard, may be used. In addition, the Energy Management Plan Reporting Tool (PDF) and the Operations and Maintenance Reporting Tool (PDF) must be attached to the successful early compliance applications.

    Tip: Designate an energy manager and identify your qualified person. A qualified person requires specific expertise and certification. Select this link for defined roles and responsibilities (PDF).

    Use the EMP template and the O&M Program Development Tool to help get you started. The use of the template and tool are not required. You are welcome to use other templates or existing documents that meet the requirements of the CBPS.

    The EMP template acts as a framework for building energy management planning in relation to the requirements of the CBPS. This optional resource can be used by building owners, authorized representatives, energy managers, or qualified persons to guide the creation of the energy management plan for Tier 1 or Tier 2 covered buildings. An EMP outlines an organization’s goals for their building’s energy performance, tracks actual energy use of the building, reports historical energy use intensity (EUI) metrics compared to the building’s energy use intensity target (EUIt), and incorporates O&M protocols to ensure the building is operating as efficiently as possible.

    The O&M Program Development Tool was developed to assist building owners with documenting and tracking a building’s equipment and system inventory and maintenance tasks associated with their equipment. This excel-based tool allows building personnel to track common equipment types and tasks as well as create their own customizable equipment and maintenance requirements. Watch the simple or detailed tutorial on how to navigate the tool:

    The building owner of a Tier 1 covered building must report compliance with the standard to Commerce in accordance with the initial compliance schedule and every five years thereafter.

    Need more time to comply?

    Conditional compliance is a temporary compliance method that can be applied to avoid the penalty if the EUIt or Investment Criteria will not be met by the scheduled compliance date. See Annex Z4 for more details. Application for conditional compliance must be submitted a minimum of 180 days prior to the scheduled compliance date. 

    Commerce is authorized to impose administrative penalties upon building owners who fail to submit documentation demonstrating compliance. Failure to submit appropriate documentation by the scheduled reporting date will result in progressive penalties by legal notice.
