The intent of this prerequisite is to ensure building's energy related systems are installed, calibrated and perform according to the owner's project requirements, basis of design, and construction documents.

Requirements for Certification:

Designate an individual as the Commissioning Authority (CxA) to lead, review and oversee the completion of the commissioning process activities.

The Owner shall document the Owner's Project Requirements. The design team shall develop the Basis of Design. The CxA shall review these documents for clarity and completeness. The Owner and design team shall be responsible for updates to their respective documents.

Develop and incorporate commissioning requirements into the construction documents. Develop and implement a commissioning plan.

Verify the installation and performance of the systems to be commissioned. Complete a summary commissioning report.

Successful Strategies:

  • Commissioning agent should coordinate and organize regularly scheduled meetings with the contractors and subcontractors on-site.
  • Incorporate the commissioning agent's milestones into the project schedule.


Helpful Hints:

  1. The commissioning agent should be contracted early in the design process, ideally during schematic design or design development stages.
  2. The scope of work for this prerequisite offers synergies and potential cost savings for the additional commissioning activities in credit EAc3 and measurement and verification activities in credit EAc5.
  3. The commissioning agent must be independent of the design and construction team for projects over 50,000 square feet, although they may be employees of the firms providing those services.
  4. See requirements of Cal/OSHA Minimum building Ventilation Standard, Title 8, Section 5142. http://www.dir.ca.gov/title8/5142.html


Historical Data (updated June 2006):

  • Building commissioning is a prerequisite for LEED certification and must be met.
