Radford University has implemented many energy conservation measures over the years. Some of these measures are listed below.

Replace Lamps and Ballast	Upgrade lighting to energy efficient lamps and electronic ballast.
Occupancy Sensors	Infared and ultrasonic sensors are used to turn lights off after a set period of time.
Free Cooling	Use of cooling towers and plate heat exchangers to provide cooling without running mechanical cooling equipment.
Ice Storage	Use of ice storage system to use ice for cooling instead of running mechanical cooling equipment
Economizer	Uses outside air for cooling instead of running mechanical cooling equipment.
Steam Driven Condensate Pumps	Uses steam to drive a condensate return pump instead of electricity.
Carbon Dioxide Sensors	Uses CO2 sensors to control the amount of outside air entering a building.
Variable Frequency Drives	Used where motors vary in speed to control pumps, etc. Varying the speed saves electricity.
Improve Insulation	Improve and increase insulation in buildings,on circulating lines and steam lines.
Replace Windows	Replace windows with energy efficient thermopane glass.
Heat Reclaim	Capture heat in exhaust air and transferthe heat back in the space.
Hot Water Reset	Control the temperature of heating water determined by outside air temperature.
Chiller Reset	Control the temperature of cooling water determines by outside air temperature.
Energy Efficient Motors	Replace electric motors with energy efficient motors.
