Successfully retrofitting aging K-12 schools using energy conservation measures (ECM) that can improve the physical plant and reduce energy consumption are explored. Topics explore how certain ECM measures can benefit educational facilities, why retrofitting begun sooner rather than later is important, how to finance the retrofit program, and the phases retrofit programs have in common. Contracting strategies for school districts that choose not to use Energy Savings Companies (companies providing design, construction, and financing with a guaranteed construction cost and energy savings component) are also examined, as well as the pros and cons of both strategies.
