Detroit Public Schools Energy Manager Emile Lauzzana is tasked with finding any and all ways to cut the energy usage across one of America’s largest public school districts — one that includes 50,000 students, more than 100 schools and a dozen support facilities. Cutting costs is the name of the game for the cash-strapped district, which operates a utilities budget of $18 million (which goes toward electricity, natural gas, steam, water and sewer service). Lauzzana has now implemented the “Go Green Challenge,” an energy-saving behavioral program aimed at raising energy awareness and driving cost savings through various eco-minded projects. “What we are providing is a structure for participation in sustainability,” Lauzzana explains. “This is something that people have wanted for a long time in the district. People are just really excited about it.”
