Intent

To further 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.

Requirements

Option 1. Enhanced commissioning (4 points)
Projects must complete the following commissioning process (CxP) activities for mechanical, electrical, domestic hot water, and renewable energy systems and assemblies in accordance with ASHRAE Guideline 0–2005 and ASHRAE Guideline 1.1–2007 for HVAC&R systems, as they relate to energy, water, indoor environmental quality, and durability.
  • Review contractor submittals.
  • Include systems manual requirements in construction documents.
  • Include operator and occupant training requirements in construction documents.
  • Verify systems manual updates and delivery.
  • Verify operator and occupant training delivery and effectiveness.
  • Verify seasonal testing.
  • Review building operations 10 months after substantial completion.
  • Develop an on-going commissioning plan.

OR

Option 2. Monitoring-based commissioning (5 points)
Achieve Option 1. Develop monitoring-based procedures and identify points to be measured and evaluated to assess performance of energy- and water-consuming systems. Include the procedures and measurement points in the commissioning plan. Address the following:
  • roles and responsibilities;
  • measurement requirements (meters, points, metering systems, data access);
  • the points to be tracked, with frequency and duration for trend monitoring;
  • the limits of acceptable values for tracked points and metered values (where appropriate, predictive algorithms may be used to compare ideal values with actual values);
  • the elements used to evaluate performance, including conflict between systems, out-of-sequence operation of systems components, and energy and water usage profiles;
  • an action plan for identifying and correcting operational errors and deficiencies;
  • training to prevent errors;
  • planning for repairs needed to maintain performance;
  • the frequency of analyses in the first year of occupancy (at least quarterly);
Update the systems manual with any modifications or new settings, and give the reason for any modifications from the original design. See all forum discussions about this credit »

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.

Reference Guide Correction
Description of change:
EA Prerequisite Fundamental Commissioning and Verification: STEP-BY-STEP GUIDANCE:
In Step 3. Engage Commissioning Authority, replace the third bullet with the following text:
"The CxA will lead, review, and oversee the Cx process for all systems to be commissioned, including both Fundamental and Enhanced commissioning activities if Enhanced Commissioning is pursued (see Further Explanation, Systems to Be Commissioned)."

After the end of Step 3. add the following text:
"Exception: For projects pursuing Enhanced Commissioning Option 2, envelope commissioning, the building envelope commissioning agent (BeCxA) may be completely independent of the lead CxA, and oversight of envelope commissioning activities by the lead CxA is not required as long as the BeCxA meets all of the enhanced commissioning credit requirements for the Commissioning Authority relative to the envelope systems that will be commissioned.

The use of the phrase “lead, review and oversee” defines a high level of participation while providing some flexibility for fitting the process to the project.

Therefore, at a minimum, the lead commissioning agent should be participating in ALL commissioning activities including BOTH fundamental and enhanced commissioning activities. The exact level of leading, reviewing, and overseeing can vary based on individual project scenarios. However, for enhanced commissioning, the entity selected as the lead CxA must complete the following tasks at a minimum:

Fundamental commissioning tasks to be performed by lead CxA:
• Review owner’s project requirements and basis of design during the early design phase.
• Conduct commissioning design review prior to mid-construction documents
• Confirm incorporation of Cx requirements into construction documents.
• Develop or approve construction checklists.
• Develop or approve system test procedures.
• Witness at least a portion of the mechanical, electrical, plumbing, and (if applicable) renewable system functional testing that verifies installation and performance of commissioned systems. Refer to ASHRAE Guideline 0 for additional guidance.
• Review an issues log throughout the Cx process. If the CxA does not directly update the log, the CxA must approve all updates to the log on a continuous basis.
• Report findings directly to the owner throughout the process.
• Develop or approve the summary commissioning report.

Enhanced Commissioning Tasks to be performed by lead CxA:
• Review contractor submittals applicable to systems being commissioned.
• Develop or approve systems manual updates and delivery.n
• Verify operator and occupant training delivery and effectiveness.
• Perform seasonal testing.
• Develop or approve an ongoing commissioning plan.
• Develop or approve a monitoring-based commissioning plan.
• Review building operation within 10 months after substantial completion.

EA Credit Enhanced Commissioning: FURTHER EXPLANATION: Choosing an Appropriate CxA:
Replace the first two bullets with the following text:
• Multiple team members from different companies may collaborate to complete the commissioning scope of work. However, one CxA must lead, review, oversee, and coordinate all activities and deliverables provided by the commissioning team.
• The members of the commissioning team can be employees of the same company or employees of separate firms, provided they all meet the basic requirements for the task to which they are assigned.

In BD+C, add the following new bullet at the bottom of the list:
• For projects pursuing Option 2, envelope commissioning, the building envelope commissioning agent (BeCxA) may be completely independent of the lead CxA, and oversight of envelope commissioning activities by the lead CxA is not required. However, in this case, the BeCxA must meet all credit requirements for the Commissioning authority. Specifically:
o The BeCxA must have documented envelope commissioning process experience on at least two building projects with a similar scope of work.
o The BeCxA may be a qualified employee of the owner, an independent consultant, or a disinterested subcontractor of the design team.


Update 7/2/18: The paragraph that reads "Exception: For projects pursuing Enhanced Commissioning Option 2, envelope commissioning, the building envelope commissioning agent (BeCxA) may be completely independent of the lead CxA, and oversight of envelope commissioning activities by the lead CxA is not required as long as the BeCxA meets all of the enhanced commissioning credit requirements for the Commissioning Authority relative to the envelope systems that will be commissioned", above, is only applicable to BD+C projects.

LEED Interpretation
Inquiry:

The LEED Rating system requirements for Fundamental Commissioning include a note regarding Enhanced Commissioning: “Project teams that intend to pursue EA Credit Enhanced Commissioning should note a difference in the CxA qualifications: for the credit, the CxA may not be an employee of the design or construction firm nor a subcontractor to the construction firm.” The v4 Reference guide for Enhanced Commissioning also says: one CxA must oversee and coordinate all activities and deliverables provided by the commissioning team.”

What specific responsibilities does “oversee and coordinate” entail in a case where more than one CxA from separate companies are engaged to complete commissioning tasks?

Ruling:

The use of the phrase “oversee and coordinate” defines a high level of participation while providing some flexibility for fitting the process to the project.

Therefore, at a minimum, the lead commissioning agent should be participating in ALL commissioning activities including BOTH fundamental and enhanced commissioning activities. The exact level of leading, reviewing, and overseeing can vary based on individual project scenarios.
