The primary purpose of Energy Audit is to reduce the energy costs and improve the energy efficiency. In this comprehensive study, various factors such as energy consumption trends, connected loads, and energy layout were meticulously analyzed through a detailed audit conducted at Govt. Model Engineering College in Kochi. Furthermore, a cost benefit analysis was performed, giving insightful recommendations on more efficient approaches to reduce energy consumption and associated costs. Identification of the other issues at college which were causing the decline in energy efficiency was a key outcome of this study. The data and information collected from this study is documented.
