Answer: C

Explanation:

According to the LEED Reference Guide for Building Design and Construction1, the Indoor Environmental Quality Credit, Indoor Air Quality Assessment, Option 1. Flush-Out requires the project to perform a building flush-out by supplying a total air volume of 14,000 cubic feet of outdoor air per square foot of gross floor area while maintaining an internal temperature of at least 60°F and no higher than 80°F and relative humidity no higher than 60%. The gross floor area of the building is 1,000 ft2 and the ceiling height is 10 ft, so the required volume of supply air for the entire building flush-out is:

14,000 ft3/sf x 1,000 sf = 14,000,000 ft3
