Every occupant in a building creates demand for lighting, ventilation, thermal comfort, and electrical power. Lighting, heating, and cooling unoccupied spaces is a huge source of energy waste in buildings, and many studies have shown that building occupancy profiles have a significant impact on building energy use and operational controls.
Closer alignment of occupancy patterns to building equipment schedules can be an effective low-cost/no-cost energy efficiency strategy leading to more intelligent control of buildings, a better balance between occupant comfort and energy savings, and lower utility bills. This includes, but is not limited to, HVAC temperature set points, lighting schedules, and economizer schedules.
