Energy engineers and constructing managers are becoming increasingly conscious of the benefits of occupancy sensors. First launched more than a decade in the past for security use (which continues to be a peripheral performance profit), occupancy sensors at this time are used to help scale back the mounting prices mirrored within the monthly electric bill. For instance, they can achieve power financial savings of 25 to 50% in virtually any building with only minor modification of the prevailing lighting system. As lighting can symbolize as much as 30% of the annual electric costs of a business constructing, such energy savings are significant and put cash again to the place it belongs--the institutional finances. If the local utility unit worth of energy is greater than eight cents, the payback will usually be less than two years. Occupancy sensors, nonetheless, remain application-sensitive gadgets. Improper positioning and setting could result in performance that fails expectations. In this text, the authors will assessment how occupancy sensors save power, then discuss correct application in order that set up is efficient in addition to power-saving--important when considering the lighting system's intent, which is to offer a high quality setting for people.
