ENERGY AUDIT FOR ROORKEE UNIVERSITY CAMPUS

Abstract

Energy conservation may be defined as more efficient or effective use of energy. For efficient use of energy at any industry, university or organisation, energy management programs are planned. Energy Audit or Energy Survey is done and it is found that where we can save the energy or use alternate energy (renewable and clean). At University of Roorkee (UOR), it is proposed to utilize Solar energy and Biomass energy for conventional energies like electric / LPG etc. Solar energy can be used for heating domestic water for residences, hostels and messes, whereas Biomass energy is converted to biogas and will be used as a fuel for cooking in messes, houses etc.Computer programs are made to know the energy distribution (present and proposed) at UOR and is represented on pie chart and bar chart. Computer programs for calculating the solar radiation intensity at Roorkee, for evaluating the capital recovery factor(CRF) and for finding the present worth of net life cycle saving are also made. After studying the collected data and making estimation it is found that near about 90% of energy is being used as electricity and L.P.G. in UOR campus. So main emphasis is given to reduce their percentage and to use solar energy and biogas energy as a substitute for electricity and L.P.G.. Two types of biogas plants, which are based upon mess waste and biomass waste (leaves, grass etc.), are suggested to be installed on the campus. Similarly three types of solar water heaters of different capacities are also suggested to be installed on the campus. By installing 6 biogas plants (3 of each type) and 146 solar water heaters (43 one-storey water heaters, 100 two-storey water heaters and 3 large capacity water heaters), on an average, 45cylinders of L.P.G. and more than 96 MWh of electricity will be saved per month. Net reduction in electrical energy is approx. 8.2% and that in L.P.G. is approx. 0.7% The present worth of net life cycle saving will be more than Rs. 26.45 lakh. So, we see that by installing the proposed project, we save not only energy but a large amount of money also. LI
