An energy audit determines where, when, why and how energy is used in a facility, and to identify opportunities to improve efficiency. Energy audits are a powerful tool for identifying operating and equipment improvements that will save energy, reduce energy costs, and lead to better efficiency. Energy audit is also known as ‘Energy Assessment’. The present study intends to review energy audit and efficiency of a complex building and identified the ways of reducing waste of energy in a complex building. This research provides an overview on energy audit which comprises of energy audit team, types of energy phase and classifications of energy audit, then energy use index. The paper also focuses on past works of energy audit on hospital buildings, academics building and other buildings. Finally, the results reveal that air-conditioners consume more energy followed by office equipment and then lighting. It was also found that energy wastage was as a result of higher energy consuming equipment and its usage during unoccupied hours.
