to begin the commissioning process early during the design process
and execute additional activities after systems performance
verification is completed.
Prior to the start of the construction documents phase, designate
an independent Commissioning Authority (CxA) to lead, review, and
oversee the completion of all commissioning process activities. The
CxA shall conduct, at a minimum, one commissioning design review of
the Owner's Project Requirements (OPR), Basis of Design (BOD), and
design documents prior to mid-construction documents phase and
back-check the review comments in the subsequent design
The CxA shall review contractor submittals applicable to systems
being commissioned for compliance with the OPR and BOD. This review
shall be concurrent with A/E reviews and submitted to the design
team and the Owner.
Develop a systems manual that provides future operating staff the
information needed to understand and optimally operate the
commissioned systems. Verify that the requirements for training
operating personnel and building occupants are completed.
Assure the involvement by the CxA in reviewing building operation
within 10 months after substantial completion with O&M staff
and occupants. Include a plan for resolution of outstanding
- Commissioning agent should coordinate and organize regularly
scheduled meetings with the contractors and subcontractors
- Incorporate the commissioning agent's milestones into the
- The commissioning MUST be contracted prior to 50% CDs.
- Some requirements for this credit occur just prior to
substantial completion. Note that LEED requires that documentation
is "readily available" prior to submittal.
- When a Commissioning Authority reviews key submittals for
compliance with the specifications and design intent, the whole
project team benefits by getting an extra set of eyes to look at
the details of equipment and control integration at a very early
phase of the project. These reviews can help to integrate the
equipment suppliers and control vendors prior to equipment being
ordered, which facilitates on-site integration and keeps
"head-scratching" to a minimum.
- Project teams should be aware of the credit synergies with EAp1
when scoping and bidding this credit.
- Check for more favorable terms of professional liability
- Consider including an ongoing training component to strengthen
the training beyond the commissioning prerequisite. This should be
integrated in the IAQ Management Plan.
- Include an IAQ Management Plan as part of the Facility
Maintenance and Commissioning Plans.
- 52% of all California LEED Certified projects achieved this
credit under LEED v2.1.
