Offutt Air Force Base is one of the most respected and widely recognized military bases in the world, this command center’s mission is to “deter military attack on the United States and its allies, and should deterrence fail, employ forces so as to achieve national objectives.”
Located in Omaha, the Strategic Air Command employs men and women from all four forces (Air Force, Army, Navy and Marines) to preserve peace throughout the world.
1. Client Challenge:
Offutt Air Force Base, dealing with government budget cuts, needed to upgrade their lighting to lower their energy costs. With over 5 million sq. ft. of buildings had some interesting security challenges in accomplishing their energy and lighting needs.
RTS performed an audit of 49 buildings on the base. RTS evaluated vast numbers of variables such as how the space will be used, amount of day-light, load potential, dimming, lamp color, initial cost, and cost to maintain moving forward.
2. Lighting Solution:
Retro-Tech performed a base wide lighting upgrade encompassing over 5,000,000 sq.ft. Prior to engineering a lighting upgrade of this magnitude for a secure military facility, careful consideration was given to two issues at the base that presented potential problems; 1) access was severely limited in certain buildings, and 2) the utility rate at the base is extremely low. Therefore, a unique lighting design was required in order to achieve an acceptable payback. In addition to T8 lamps, electronic ballasts, LED exit signs, and compact fluorescents, over 2,100 HI/LO pulse start metal halide luminaires were installed throughout the base.
Retro-Tech Systems, Inc., in conjunction with a major manufacturer, developed an HID fixture in which the occupancy sensor mounts directly to the fixture. The sensor design considerably reduced the installation time helping to provide an attractive payback. In addition, the 300 watt pulse start metal halide system replaced 400 watt high pressure sodium. With an increased fixture efficiency, the base now receives higher foot-candle readings.
Retro-Tech Systems, Inc. also performed a controls upgrade on the tarmac lighting. RTS installed a single photocell to control the tarmac lighting on seven 100′ poles spaced 200′ apart. This installation will allow easier maintenance for the base.
3. The Results:
The overall results are impressive. The lighting kW and kWh were reduced 54% while improving light levels. The new lighting systems has been standardized which will provide a reduction in long term maintenance costs for the base.
