Branham Electric: Wainwright Industries
Branham Electric was recognized for its work on the energy efficient lighting retrofit contract for two Wainwright Industries' St. Louis area facilities in August 2013.
The first building, located in Wentzville, Missouri, was a 500,000-square-foot manufacturing and warehouse facility with existing lighting averaging 20 foot candle. The retrofit boosted the lighting parametric to an average of 50 foot candle. This project involved replacing hundreds of metal halide fixtures and industrial strip fixtures with high-performance florescent fixtures.
The lighting system required extensive electrical work, including rewire and removal. Branham Electric supplied and installed 34 new 277V branch circuits. Wainwright also required that 50 percent of the entire facility's lighting b powered by a back-up generator.
In this portion of the project, the new lighting system's annual kWh savings is 1,256,062 kWh and an annual electrical savings of $99,406. There was also EPA-certified recycling of all existing light fixtures, lamps, and ballast to further add to the green nature of the project.
The second building, located in Fenton, Missouri, was a 433,622-square-foot warehouse. This building also had an average of 20 foot candle lighting that was upgraded to an energy-efficient system with a 50 foot candle average. In addition to hundreds of fixtures being replaced, all new Fbay fixtures included infrared motion-controlled occupancy sensors to enable Wainwright to receive additional energy savings.
The savings on the Fenton warehouse was 147,878 kWh annually and $11,683 in electrical savings annually. Branham Electric was able to secure a larger cash incentive rebate from Ameren Missouri for Wainwright as well.
Branham Electric has the added challenge of scheduling this project around a 24/7, five-day-a-week schedule at the Wentzville facility. Branham Electric mapped their processes around the production floor to coordinate the work. Branham Electric also needed to avoid creating debris in automated work areas. Modular connectors and protection covers were used to solve this challenge.
