Our team decided to perform air quality testing before occupancy on a recently completed building. We have had some question over which method is required for tVOC testing and for what compounds.

Our project has 4 garage levels. There are 3-4 elevator lobbies on each level. The lobbies are small and receive OA from RTUs serving the offices above.

I am working on a project that has multiple AHUs serving different types of spaces and we also have several large mechanical and electrical rooms.
