Inquiry

The open section of our distribution center is approximately 540,000 sf and is essentially one large room with open racks, a 37\' high clg and peak occupancy of 76 people (approx. 7100 SF per person). There are 6 identical rooftop heating units and 13 makeup air units, each serving about 90,000 sf. Since the project is pursuing EQc4.1and EQc4.2 there are no presumed contaminate sources in the building materials in this space (concrete slab, precast concrete walls, steel deck and steel racks) and given that this is a completely open distribution center with an active destratification system, we expect absolutely no deviation in the test results in each area. Therefore, we are proposing to test the six zones served by the rooftop units with one test canister in each zone. We believe this strategy is the most fiscally and environmentally responsible one for this project type-an open distribution center. Sampling every 25,000 sf instead of 80,000 sf would waste money that is preferred for other green strategies, and would waste natural resources embodied in the canisters. Please comment on the 90,000 SF testing zone. If higher-than expected contaminant levels are detected in the process, we will flush-out the building and retest. Air quality testing in the remainder of the building including 10,000 SF to 12,000 SF of offices will meet the criteria in the reference manual.
