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.
    1. The CxA shall have documented commissioning authority experience in at least two building projects.
    2. The individual serving as the CxA shall be—
      1. independent of the work of design and construction;
      2. not an employee of the design firm, though they may be contracted through them;
      3. not an employee of, or contracted through, a contractor or construction manager holding construction contracts; and
      4. (can be) a qualified employee or consultant of the Owner.
    3. The CxA shall report results, findings and recommendations directly to the Owner.
    4. 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.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.
