In any public building, there are lots of public rooms, such as libraries, computer rooms, lounges, workout rooms, meeting rooms and so on; for these require a simple but effective control system.
For these common rooms there are those that are open (e.g. libraries), and there those that are restricted (e.g. meeting rooms), what simple and effective way is there to manager their energy use?
Often encountered is the problem of the last occupant leaving but both the lights and a/c are left on; which results in much wasted energy and thus becomes the focal point of any energy conservation measure.
During idle periods, such as late nights and holidays, it is desired to have some way to administer them but without having to roam around to operate them.
The ACS can forcibly control the lights during busy periods; at other times, the local controls are authorized and control reverts to th local switches or sensor, the user is then allowed to manually control the lights.
