Inquiry

We request further clarification of the EQc1 credit requirements as they apply to multi-family and mixed-use projects. Our project is a 247-unit condominium building with an underground parking garage. We intend to follow the residential compliance path discussed in the 9/3/2004 CIR. 1) We will provide CO2 monitoring in the high-occupancy spaces (fitness center, conference room, swimming pool and social room), which will be wired to the Building Management System (BMS). 2) We intend to provide CO monitoring, as described in the CIR; in the parking garage, boiler rooms, and in each dwelling unit. 3) We also intend to implement a yearly monitoring system to test for IAQ contaminants. Please clarify the compliance path as it applies to parts 2 and 3: 2) CO monitoring is not required for commercial projects to capture the EAc1 credit. Please confirm if CO monitoring of the parking garage and boiler rooms, which are base-building/common-use spaces as opposed to dwelling units, is required for multi-family and mixed-use projects. 3) The 9/20/2004 ruling states that the measurement of the chemicals listed in the 9/3/2004 inquiry is not required. Please clarify precisely what indoor air contaminants must be tested and the accepted thresholds for each contaminant in order to capture the credit.
