15. Increased ventilation
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.
The following is required in terms of the rate of outdoor air supply to all regularly occupied spaces:
