aSchedules for occupancy, lighting, receptacle, HVAC system, and service hot water are from ASHRAE Standard 90.1-1989 and addendums, except that 5 percent emergency lighting has been added for all off hours. Elevator schedules, except for restaurants, are from the U.S. Department of Energy Standard Evaluation Techniques except changed to 0 percent when occupancy is 0 percent. These values may be used only if actual schedules are not known. |
bLighting profiles are modified to reflect the requirement for occupancy sensors in Section C405.2. |
