To support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability.
Commissioning Process Scope
Complete the following commissioning
) process activities for mechanical, electrical, plumbing, and renewable energy
systems and assemblies, in accordance with ASHRAE Guideline 0-2013 and ASHRAE Guideline 1.1–2007 for HVAC&R Systems, as they relate to energy, water, indoor environmental quality, and durability.
- Develop the OPR.
- Develop a BOD.
The commissioning authority
) must do the following:
- Review the OPR, BOD, and project design.
- Develop and implement a Cx plan.
- Confirm incorporation of Cx requirements into the construction documents.
- Develop construction checklists.
- Develop a system test procedure.
- Verify system test execution.
- Maintain an issues and benefits log throughout the Cx process.
- Prepare a final Cx process report.
- Document all findings and recommendations and report directly to the owner throughout the process.
Requirements for exterior enclosures are limited to inclusion in the owner’s project requirements (OPR
) and basis of design
), as well as the review of the OPR
and project design. ASTM
E2947-16: Standard Guide for Building Enclosure Commissioning provides additional guidance.
The review of the exterior enclosure
design may be performed by a qualified independent member of the design or construction team (or an employee of that firm) who is not directly responsible for design of the building enclosure
for the project.
Commissioning Authority Qualifications
By the end of the design development phase, engage a commissioning authority
with the following qualifications.
- The CxA must have documented commissioning process experience on at least two building projects with a similar scope of work. The experience must extend from early design phase through at least 10 months of occupancy;
- The CxA may be a qualified employee of the owner, an independent consultant, or an employee of the design or construction firm who is not part of the project’s design or construction team, or a disinterested subcontractor of the design or construction team.
- For projects smaller than 20,000 square feet (1 860 square meters), the CxA may be a qualified member of the design or construction team. In all cases, the CxA must report his or her findings directly to the owner.
Current Facilities Requirements and Operations and Maintenance Plan
Prepare and maintain a current facilities requirements
and operations and maintenance plan
that contains the information necessary to operate the building efficiently. The plan must include the following:
- a sequence of operations for the building;
- the building occupancy schedule;
- equipment run-time schedules;
- setpoints for all HVAC equipment;
- set lighting levels throughout the building;
- minimum outside air requirements;
- any changes in schedules or setpoints for different seasons, days of the week, and times of day;
- a systems narrative describing the mechanical and electrical systems and equipment;
- a preventive maintenance plan for building equipment described in the systems narrative; and
- a commissioning program that includes periodic commissioning requirements, ongoing commissioning tasks, and continuous tasks for critical facilities.
Interior Design and Construction projects are responsible for completing the above tasks for all systems and equipment included in their scope, including items furnished by the base building
, but modified or relocated as part of tenant fit-out. Information such as sequences of operations, schedules, equipment setpoints, and outside air requirements for tenant equipment and spaces must be coordinated with base building
