OPTIMIZATION OF ENERGY CONSUMPTION IN AN INDUSTRY BY USING EP-OP AND TOPSIS METHOD

Maintenance of good indoor environment condition in buildings requires increased investment and possible higher energy consumption. To reduce the cost of the indoor environment of axes metrology is focused on the relation between investment cost for HVAC equipments as well as decreased energy consumption and improved performance of occupants in office building. For this, EP-OP method is applied to collect the data and then TOPSIS method is applied on the collected data which is the technique for order preference by similarities to ideal solution. To obtain the best possible result in which, the energy consumption cost is reduced without reducing the Illumination Efficacy with fare employee satisfaction. TOPSIS analysis is a practical application to verify the collected data. First the initial data is collected with the help of EP-OP method, and then the data collected is analyzed by TOPSIS analysis. After completion of successful TOPSIS analysis, data processing is being done. By using TOPSIS method, energy consumption cost will be decreased up¬-to Rs. 16000 per year of the present investment on the improvement of the indoor air quality and light illumination without any retrofitting and financial investment.
