A contractor will conduct a phased flush out of a building. The office building is 75,000 SF. What volume of air is required for flush out before occupancy begins for Indoor Environmental Quality Credit, Construction Indoor Air Quality Management Plan-Before Occupancy?
A: 1,050,000,000 cubic feet
B: 262,500,000 cubic feet
C: 225,000,000 cubic feet
D: 787,500,000 cubic feet

参考答案: B

本题解释:
Reference: Indoor Environmental Quality Credit, Construction Indoor Air Quality Management Plan-Befo

For a phased occupancy the credit requires 3,500 cubic feet of air needed per square foot of building area before occupants can move and and the rest of the flush out continues untill each SF has had 14,000 cubic feet of air pass through.

75,000SF X 3,500 = 262,500,000 cubic feet needed before the occupancy can begin under this phased flush out plan.

Note that \'during construction\' can be confused with \'pre-occupancy\' because there are no occupants in the building. However these two terms describe different periods of time in construction as considered in the LEED rating system.
