Sustainability: Cherokee County (N.C.) School District
Energy bills were consuming 25 percent of the district's budget five years ago. To address this challenge, the department instituted an energy-conservation program and energy-infrastructure conversions focused on lighting-replacement projects. All T12 lamps were replaced with T8 or T5 lamps. Every gymnasium with mercury-halogen lights now has T5 instant on/off fixtures. Every incandescent bulb was replaced with an LED lamp. One lighting experiment involved converting the smallest school to LEDs. The project achieved a cost avoidance of 39.83 percent for one month. The district's total cost avoidance from the projects is about $1.3 million.
