The guidelines put forth by ASHRAE provide the basis for acceptable indoor air quality, but not necessarily for best-in-class air quality for buildings. Unusually high building occupancy, a high risk of accidents that might degrade air quality or space capacity to install filtration make exceeding ASHRAE requirements a worthwhile strategy.

This feature requires buildings to design and supply rates of fresh air that are 30 percent higher than typically provided.

Part 1: Increased Fresh Air Supply

The following is required in terms of the rate of fresh air supply to all regularly occupied spaces:

a.1 Exceed ASHRAE fresh air supply rates met in the WELL Ventilation Effectiveness feature by 30%.
