AND/OR | |
Option 2. Continuous Indoor Air Monitoring | 1 |
Option 1. Preoccupancy Air Testing (1–2 points)
After construction ends and before occupancy, but under ventilation conditions typical for occupancy, conduct baseline IAQ testing. Retail projects may conduct the testing within 14 days of occupancy. The number of measurements should be specified according to Table 1 and taken in respective locations of the building.
Table 1. Number of measurements required for preoccupancy air testing
| Total occupied floor area, sq. ft (sq. m.) | Number of measurements |
|---|---|
| ≤ 5,000 (500) | 1 |
| > 5,000 (500) and ≤ 15,000 (1,500) | 2 |
| > 15,000 (1,500) and ≤ 25,000 (2,500) | 3 |
| > 25,000 (2,500) and ≤ 200,000 (20,000) | 4 plus one additional measurement per each 25,000 sq. ft. (2,500 sq. m.) above 25,000 sq. ft. |
