BEST COMMERCIAL PROJECT (PRIVATE)
Located in Detroit’s historic Corktown neighborhood, the IBEW Local 58 serves 4,700 members throughout Southeast Michigan. After deciding to commit to energy efficiency, the headquarters of IBEW Local 58 quickly took its place as the largest net-zero energy center in the state of Michigan. To get there, it took an incredible effort from dozens of Michigan businesses—as well as more than 500 LED lights; 600 solar panels; energy-efficient windows and doors; a structural insulated panel system; and much more. Through this project, the headquarters increased its ENERGY STAR® rating from 37 to an impressive 95, ranking them in the 95th percentile of buildings in similar climates. The building also reduced energy use by 76 percent, and IBEW Local 58 expects to lower their annual electric bill by an incredible $56,957.
IBEW Local 58 is making zero net energy happen at its Detroit headquarters
Originally constructed in 1964, the retrofitted union hall features a 600-solar panel array and solar DC-to-AC power inverters, geothermal grid, environmentally-friendly heating and cooling system, more than 500 LED lights, energy efficient windows and doors, synthetic rubber roofing system, and structurally insulated panel and Vaproshield water resistance barrier systems for walls. There's also a virtual energy monitoring system that keeps lights off when people aren't around.
