The calculation of regularly occupied space can be fine-tuned as decisions for “fixed” (attached to a wall) counters with overhead cabinets and equipment are integrated into the design. The square footage where the cabinets and equipment are located is not considered occupiable space, and therefore is not included as part of the view or the daylight calculation. For example, if an office is 500 ft2 in total, but fixed counters and cabinets occupy 100 ft2, the regularly occupied space of the room is only 400 ft2.
