Information : Energy Management Plan
The Stafford County Public Schools addressed a costly energy issue in 1989 by installing an energy management system. Previously, heating, ventilation, and air conditioning maintenance requests resulted in an employee being dispatched to the facility to investigate the problem. The employee transit time as well as vehicle expenses were time consuming and extreme. Stafford County also recognized that setbacks on the temperature during times that the building was not in use could save on energy costs.
Barber Coleman, Inc. was selected as the energy management consultant and controls supplier. Since 1989, ten facilities have been connected to the system with four more scheduled to be connected by the third quarter of 1994. The system monitors air temperature, regulates air discharge, and controls the heating, ventilation, and air conditioning system for special school functions. Operations and Maintenance personnel were previously not promptly informed of special functions. Now, the function host sends a facsimile request for the time period that the facility will be in use, and the system is programmed at the Operations and Maintenance facility to control the climate for that period. In the spring of 1994, the Trane Company was selected to provide the energy control system for a new facility under construction.
Problems are investigated at the Operations and Maintenance facility without dispatching personnel to the building. Monthly comparison data is maintained to identify equipment that may need additional maintenance performed, and emergency heating, ventilation, and air conditioning calls have been significantly reduced. The supervisor can also access the system with a personal computer from his home to troubleshoot problems or adjust the system if necessary during weekends, off-hours, or holidays. Personnel can now dedicate more time to preventive maintenance operations on regular 120-day intervals.
