Approved equivalent standards Projects may use IECC 2021 [34] in lieu of ASHRAE Standard 90.1-2019 and IECC 2024 [35] in lieu of ASHRAE Standard 90.1-2022 . Projects that use IECC instead of ASHRAE must still comply with all additional LEED ID+C rating system requirements.

Selecting the CxP As buildings and systems become more complex and as the systems required for Cx expand beyond traditional mechanical equipment, many CxPs will consist of a team instead of an individual person. Therefore, either an entity or an individual can act as the CxP. For projects that use a CxP entity, designating a single person as the Cx project lead or manager ensures consistency in documentation and quality control of the process.

Minimum qualifications The CxP must have direct commissioning experience from the design phase through the construction phase for at least two projects with equal or larger scope and complexity. The previous experience should address projects of similar types and size range, similar types and capacities of HVAC and SWH equipment, and controls with similar complexity.

Experience documented for a CxP entity must reflect the team performing the commissioning work for the project.

Eligible entities Per ASHRAE Standard 90.1-2019, Section 4.2.5.2 , the CxP must be completely independent from the design or construction team. Consider the following when selecting a CxP:

  • The CxP can be a third-party entity not currently contracted for any design or construction aspects of the project.

  • The CxP can be employed by the owner, provided that the entity meets the CxP minimum qualifications.

  • If the CxP is employed by any company that has direct influence on the design and construction, the commissioning plan must clearly address any potential conflicts of interest and demonstrate that the CxP acts and operates solely on the behalf of the owner, reports directly to the owner, and works entirely independently from the design and construction team.

  • The CxP can be employed by the company performing the design or construction of the project; however, they must be a completely independent member of the design team,
