I am working on a new Cancer Center in St. Louis, MO. We are pursuing the envelope commissioning credits and have a question regarding the requirements:

The requirements in LEED v4 for envelop Cx are unclear on prescribed testing requirements.  Our OPR & BOD for the project indicate testing requirements on the mock-up (including air infiltration/exfiltration, water infiltration, and structural testing in accordance with ASTM standards) as well as in-place water infiltration testing on the final installation and frequent installation inspections of the curtain wall, air barriers, and roof.  Are there any other prescribed testing activities that are required beyond what we planned, or would our testing plan suffice so long as it meets the code standards indicated in the credit?

Any assistance to help clarify would be greatly appreciated. We want to make sure we are taking the appropriate steps to achieve the credits while being good stewards or our clients budget. 

Thank you!
