Energy Audit and Management of a College

Abstract

Educational Institutions are the major contributors to energy intensive operations in India. Energy cost is one of the problems in the institute’s budget. Electricity consumption can be reduced with targeted efforts and by using various energy management methods. Resultant energy saving provides a venue for the reinvestment in the educational institute itself. This paper presents an energy audit of the college site (Amal Jyothi College of Engineering, Kottayam). The review begins by gathering data of all the feeders in the college and the past record of electricity bills. This data is then inspected to realize how much energy is used. The load curve of each feeder in the college along with the power consumption data was obtained. From the above data we noticed that some buildings consume more energy. So, we mainly concentrated on these buildings that are RB (Resource Block), STP (Sewage Treatment Plant), Laundry and Kitchen. The data are obtained using some devices such as power quality and energy analyzer, clamp meter and lux meter. Power quality analyzer technology tracks numerous electrical parameters which include voltage, current, frequency, peak demand, harmonic distortion etc. Lux meter is used to measure the lumens and clamp meter is used to measure the power respectively. After analyses of this readings, we have suggested some of the energy and demand side management that can be implemented in each of this buildings so that energy consumption can be reduced to a minimum level. Time of working of all the buildings was also analyzed along with the data.
