The Town Center parking deck had 138 high pressure sodium light fixtures and 52 florescent fixtures. High pressure sodium light fixtures are giant users of electricity and they burned 24 hours a day, 7 days a week. None of the fixtures were equipped with daylight sensors.
We called John Coleman, sustainability coordinator for the City of Fayetteville. He put us in touch with local “green” builder Butch Coger of Custom Home and Commercial Electronics for options. We asked him to perform an electrical energy audit to determine the cost and energy savings that could be obtained if the high pressure sodium light fixtures and fluorescent fixtures were replaced with LED lighting. The study confirmed that significant savings could be obtained. Original estimates were that payoff would be 2.49 years for the replacement of 144 low bay metal halide luminaries and would save the Town Center $150,000 over 50,000 hours. Payoff for the fluorescent fixtures would be 4.52 years with savings of $6,715 over 50K.
Custom Homes & Commercial Electronics was awarded the bid by the Fayetteville Advertising & Promotion Commission to install Infinilux lighting. Cost of the turnkey upgrade was $115,481.51
The environmental impact of the reduced emissions generation from the LED lighting should result in the following savings in 5.71 years:
- Save 102,141 gallons of gasoline.
- Take 562 cars off of the road.
- Plant 230 acres of trees.
