An agreement between Johnson Controls and a Maryland school district provided financing for the initial capital expenditure to upgrade and control the heating, ventilating, and air conditioning equipment at a high school and guaranteed savings during the 5-year contract. (MLF)

Energy management systems are designed to monitor and control energy consumption. A variety of these systems is described. (MLF)

Computer-based building management systems can cut the energy costs of heating, ventilating, and air conditioning (HVAC) systems in school buildings. Administrators are advised on how to choose the best system. (MLF)

Advises administrators how to develop an energy master plan and how to reduce the usage of heating, ventilating, and air conditioning (HVAC) systems by means of a time clock, thermostat, and a scheduled preventive maintenance program. (MLF)

The installation of proper control systems is estimated as saving up to 25 percent of the energy used in schools. Other potential energy-saving areas are transmission (heat loss or gain through walls, especially ceilings); internal load (heat from students, lights, and machinery); ventilation; and equipment maintenance.

A microcomputer, when interfaced with appropriate sensing and control devices, can be used as an energy management processor to manage a building's environmental system. (Author)
