Areas less than five percent of footprint for footprints over 100,000 square feet. 1613.3 Daylight Zone Control: All daylghted zones, AS defined in Chapter 2, both under ororhesd glazing and adjacent to vertical glazing. shall be provided with Individual controls, or daylight or occupant -sensing automatic controls, which control the lights independent of general area lighting. Contiguous daylight zones adjacent to vertical glazing are allowed to be controlled by a single controlling device provided that they do not include zones facing more than two adjacent care -real orientations (I A. north, east south, west). Daylight zones under overhead glazing more than 15 feet from the perimeter shish he controlled separately from daylight zones adjacent to vertical glazing. EXCEPTION: Daylight spaces enclosed by walls or ceiling height partitions and containing 2 or fewer light fixtures are not required to have a separate switch for general area fighting. 1513.4 Display, Exhibition, and Specialty Lighting Controls: All display, exhibition, or specialty lighting shall be controlled Independently of general area lighting. 1513.6 Automatic Shut -Off Controls, Exterior.
