Inquiry

This credit requires that MERV 13 filters be installed during construction and after construction is complete. Our mix-use project includes window mounted PTAC (Package Terminal Air Conditioner) units for the Residential portion and several water cooled air handling units for the first floor grocery store. There are no MERV 13 filters made that would fit the PTAC units, so we propose to seal all openings on the PTACs with tape and plastic and not use them until after all work is substantially complete, all dust-generating activities are finished, the building is cleaned and the punch list has been completed, similar to a recent CIR. The grocery store water cooled air handling units would be unable to operate properly with the pressure drop created by the MERV 13 filters, as confirmed by the Mechanical Engineer of Record, so we propose to install MERV 11 filters instead. We propose that our strategy meets the intent of IEQ 3.1 and should qualify for the credit.
