The Lighting/BAS Convergence, Cont’d.
For most buildings, it will be a question not of if, but when.
- Occupancy/Vacancy Control.Turning off lights when space is not occupied. This can be achieved through the use of motion sen-sors, time clocks, or from a BAS schedule. Generally, private offices, classrooms, conference rooms, etc. will get occupancy or vacancy sensors, while public areas and open offices ideally will be scheduled from the BAS in coordination with HVAC.
- Daylight Harvesting. Adjusting light levels when daylight is available.
- Bi-Level Switching. The ability to control lighting using either dimming or several levels to allow the occupant to adjust light levels to their needs.
- Exterior Lighting. Bringing exterior lights and signs off during the day as well as at other selected times.
- Special Areas. Control of special areas including classrooms, conference rooms, lecture halls, and boardrooms. This often includes integrated control of lights, blinds, AV equipment, etc.
