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