Air flush

Air flush


To remediate construction-related indoor air contamination.

An air flush must be conducted throughout the entire building, including all tenant spaces where construction has taken place within the last year.

This feature allows for a pre-occupancy air flush, or a combined option with a short pre-occupancy and longer post-occupancy air flush option.

Projects which can only conduct a air flush post-occupancy, may submit an Alternative Adherence Path (AAP) for review.
