EA Credit 3: Enhanced Commissioning
1 Point
Intent
Begin the commissioning process early during the design process and
execute additional activities after systems
performance verification is completed.
Requirements
Implement, or have a contract in place to implement, the following
additional commissioning process activities
in addition to the requirements of EA Prerequisite 1 and in
accordance with the LEED for New Construction
2.2 Reference Guide:
1. 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, at
a minimum, perform Tasks 2, 3 and 6. Other team members may perform
Tasks 4 and 5.
a. The CxA shall have documented commissioning authority experience
in at least two building projects.
b. The individual serving as the CxA shall be—
i. independent of the work of design and construction;
ii. not an employee of the design firm, though they may be
contracted through them;
iii. not an employee of, or contracted through, a contractor or
construction manager holding construction
contracts; and
iv. (can be) a qualified employee or consultant of the Owner.
c. The CxA shall report results, findings and recommendations
directly to the Owner.
d. This requirement has no deviation for project size.
2. 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
submission.
3. 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.
4. Develop a systems manual that provides future operating staff the
information needed to understand and
optimally operate the commissioned systems.
5. Verify that the requirements for training operating personnel and
building occupants are completed.
6. 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 commissioningrelated
issues.
Potential Technologies & Strategies
Although it is preferable that the CxA be contracted by the Owner,
for the enhanced commissioning credit, the
CxA may also be contracted through the design firms or construction
management firms not holding construction
contracts.
The LEED for New Construction 2.2 Reference Guide provides detailed
guidance on the rigor expected for
following process activities:
- Commissioning design review
- Commissioning submittal review
- Systems manual
