Energy Audit of an Existing Building: Cooling Load Approach

Divya Jain ^[3]

Abstract: This project has been carried to perform energy audit in an office building in order to find out the energy saving measures. The objective of this project is to obtain information about the building cooling systems, lighting systems and finally to find minimal cost and building measures that can be implemented to reduce energy consumption of that building with a set of improvements of the lighting system and an extensive use of day lighting strategies. One building has been chosen for this project and a detailed energy audit has been conducted in the building with the permission from the building management. Finally there are few energy saving measures recommended for this building and the energy consumption has been found to decrease after implementing those measures in the building. The effect of significant building parameters like orientation, window glass shade type, wall insulation, roof type and floor type can be easily investigated. Effect of all these parameters have been investigated for a typical building block to arrive at an intelligent decision. Various calculations of cooling land for existing building which comes out be 404.182 KW. After that modifications have been suggested with regard to insulation provision, reduction of quantity of air-conditioners and using double glazed glass on window panes. Cooling load calculations after modifications have been done comes out to be 247.557KW thereby saving about 38.75 % of total cooling load. The objectives of the project are a) To achieve energy savings. b) To provide a high quality internal environment. c) To provide recommendations to reduce the monthly electricity bills.
