Our project is a 6 story office building, 250,000 sq feet. It is underconstruction. The owner wishes to 'resurrect' a PV covered parking structure that was in DD when it was taken off the table.

RE: Renewable energy systems must be installed and commissioned prior to project occupancy.

I have found 'no' other information concerning' this stipulation other than the "Renewable Energy Production' v2 form. 

Question: Does anyone have any experience or knowledge how we can install and commission this system post-occupancy? The owner will have permitted drawings with a contract for Cx in hand for submission.
