FAQs about EAp1 :

Our project is considering LEED after construction has begun. Can we meet the EAp1 requirements and thus be eligible for LEED certification?

Can the CxA be a member of the design or construction team?

What type of certification is the CxA required to have?

The commissioning process turned up a few issues with the commissioned systems that should be corrected. Do we have to correct these issues and include documentation of that as part of our LEED documentation?

Can the CxA be contracted through the general contractor if the owner requires a single contract for the project?

For a building with individual systems per unit, does every single system need to be commissioned?

What kinds of projects must the CxA demonstrate experience on?

What level of authority does the CxA have towards correcting inaccurate or erroneous construction?

Envelope Review for Fundamental Cx

Has anybody seen any more clarity on what level of design review is expected / required for the building envelope?  We can't find much in the way of explanation or detailed guidance on this.  There is a big difference between a member of the same arch firm or GC looking over some things vs. a specialist envelope firm, and the range in reviews could be from a few hours to dozens of hours of high level engineering work.

Anybody seen or have an example that has been approved by USGBC?  It appears you are not even required to actually submit the review, but just check the box that you did the review.

Based on a recent Reviewer's rqmts for an old LEED job, they want evidence of Training & Preventive Maint. for BE. However, rqmts for v4.1 BE Cx appear less stringent and more practical for this aspect. I'm likely to upgrade my v4 to 4.1 because of this pending further investigation.

The lack of scope for this fundamental review of the envelope has also vexed me. At this point, I would have little to give guidance to a client on what this should include. I know what I feel would be valuable, so that is what I am planning on saying...if asked.

We have to keep in mind that LEED provides a basic framework, but relies on other standards to fully establish requirements.  One standard referenced is ASTM E2813-18 Standard Practice for Building Enclosure Commissioning for example.
