Intent: 

To expel internally-generated pollutants through an increased supply of outdoor air.

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.

Part 1: Increased Outdoor Air Supply

One of the following is required in all regularly occupied spaces:

a.1 Exceed outdoor air supply rates met in Feature 03, Part 1a by 30%.
b. Follow CIBSE AM10, Section 4, Design Calculations, to predict that room-by-room airflows will provide effective natural ventilation.
