Hi Everyone,

Can someone clarify what is the extent of envelope design review by a Commissioning Authority (CxA)

1) Fundamental Commissioning

2) Enhanced Commissioning

3) if Envelope Commissioning Credits are taken.

I am confused with the LEED statement for fundamental Cx as per the guide -

Requirements for exterior enclosures are limited to inclusion in the owner’s project requirements (OPR) and 
basis of design (BOD), as well as the review of the OPR, BOD and project design. NIBS Guideline 3-2012 for Exterior 
Enclosures provides additional guidance. 
 · Develop the OPR.
 · Develop a BOD

Is the envelope design review for every LEED v4 project mandatory.
