Abstract :
At colleges and universities, energy consumption has a large impact on both financial and environmental interests. Academic buildings represent a very high energy consumption percentage compared to industry and transportation due to the need of lighting, equipment, heating, cooling and ventilation. Electric lighting is one area where energy savings are possible at reasonable cost in new buildings as well as in retrofit projects. Adding lighting controls is a simple retrofit option than reduce or turn off the lighting when a space is not in use can save a significant amount of energy. Studies conducted on a university campuses found that adding lighting controls can reduce lighting energy use 10% to 90% or more depending on the use of the space in which the sensors are installed. This study explores the importance of energy savings from occupancy sensors. Two academic buildings of Korça University were analyzed; their building information, energy consumption data and methods to project energy savings have been analyzed. The results show that an automatic control strategy (using occupancy-based controls) could eliminate a significant amount of energy waste in common areas during business hours and also controlling runaway operation after hours and on weekends.
