The facility doesn’t have any switches for the lighting. The common area lighting and individual room lighting are 100% occupancy sensor controlled and also operate LUX based meaning the lights turn-on only when there is insufficient lighting in that area. The work areas and the conference & training room lights are operated using touch panels installed in respective areas as per specific needs. A minimum selected lighting in the work area is switched-on automatically by the building automation system based on a schedule which takes care of the lighting needs in respective areas. Additional lighting can be switched-on using the touch panel only for a defined time (example: 30 to 150 minutes maximum) after which the lights turn-off automatically or when the floor becomes empty which is detected using the access control system integration. This prevents energy wastage due to people forgetting to switch-off the lights when they leave that area.
Multiple lux sensors combined with occupancy/motion sensors available today in the market have been tested by SIERRA and it was found not working satisfactorily since LUX adjustment is analog and difficult to change when needed without the help of a technician. This facility uses a few common LUX sensors (minimizing costs) and managers using individual cabins use the eFACiLiTY® Smart Building App to calibrate their individual preferences making it very much user friendly. The users have an option to override the settings as and when required using their smart phones to switch-on the lighting manually.
The facility uses 100% mercury free lighting, 100% of the normally used lighting is completely automated and has achieved a phenomenal 80% better light power density over ASHRAE standards. The building also meets the light pollution reduction requirements for green buildings.
There are touch-panels installed in the main areas of the building using which the occupants can control the lighting and air-conditioning if they have the required privileges. While switching-on such equipment, the system forces them to select the time in minutes to switch-on the device to ensure that it is not permanently left on leading to wastage of energy.
