AND/OR
Option 2. Continuous Indoor Air Monitoring (1 point)
Provide indoor air monitors for all of the following parameters:
-
Carbon dioxide (CO2)
-
Particulate matter (PM2.5)
-
Total volatile organic compounds (TVOC)
-
Temperature
-
Relative humidity
Monitors must be building grade or better and located between 3 and 6 feet (1–2 meters) above the floor.
REQUIREMENTS EXPLAINED
This credit helps the project gain a better understanding of their indoor air.
