if desired. Calculate ASEnet1000,250 for each regularly occupied space. ASE is only calculated on a room-by-room basis.
Regularly occupied spaces with ASEnet(1000,250h) greater than 20%
Based on IES’s experience to date and analysis of the study data, an ASEnet of 20% or higher is a level of concern. For spaces where ASEnet exceeds 20%, projects must work with the designer to consider architectural methods to reduce the risk of sunlight penetration or consider the use of an automated daylight management system in as many window areas necessary to guarantee that it can avoid excessive occurrence of direct sunlight within the space.
Auditoriums
- Auditoriums may be excluded from the daylight requirements.
