This research was designed to assess the potential energy savings from the use of lighting occupancy sensor management in Hanford Site amenities. The ultimate results of the research provide useful information for assessing the fee-effective use of occupancy sensor lighting management. The outcomes also embody an evaluation of the full potential financial savings from the appliance of sensors throughout the entire site. The study concerned putting sensor test equipment in a number of office areas in eight buildings which can be part of the Hanford contractor facilities. Additional testing was performed to evaluate the effects of timer sensitivity changes on potential lighting power savings. The results of this check indicated that as much as 100% additional wasted-mild power could be saved by using timer sensitivity settings as little as 2.5 min, which is lower than standard manufacturing unit settings of often 10 to 20 min. The evaluation signifies that financial savings from lighting operations are affected by the work function and number of occupants in occupied spaces. The availability of daylight in a constructing area does not seem to have any noticeable aggregate effect on the amount of wasted-mild hours in occupied or unoccupied areas. An evaluation of the full potential financial savings for all the Hanford Sitemore » included life-cycle costing that adopted the federally accepted methodology. The life-cycle price evaluation was performed for a set of potential lighting wattages throughout the constructing spaces and occupant types identified from the initial evaluation. Below current conditions, the potential financial savings is estimated to be $525,812/yr at an preliminary price of $976,824.
