The aim is to conduct an energy audit to know the energy consumption of Murtala Muhammed International Airport. It is discovered that the airport is made up of two components which are Airside and the Landside. The Airside comprises of Airfield lighting system in which the central runway and taxiway lighting system is made of Halogen fitting. Moreover the Landside component consist of the terminal building where all the lighting fittings installed are mostly fluorescent fittings and that of ground access includes external illumination are made halide, flood light and pressure intensity lamp ranging from 250W to 400W per fitting. If the energy consumption of the existing lighting system in and around the terminal building are replaced to LED fittings and energy efficient chiller that is easy to control and operate should be installed in the terminal building to replace the package unit ranging from 2PH, 10tones and 30 tones all having a total power output of 9MW with chiller unit of 2.8MW. Therefore, 6.2MW would have been saved. It will be more advantageous and will provide some level of relief on the load consumption with significant cost saving made in terms of bill payment to the electricity provider. The energy audit was centered on three major components which include the lighting system, HVAC systems, electric motors, Fault Statistics and Recovery Time, Feeder peak load & Feeder base load. Energy inspections were carried out facility by facilities across this airport so as to develop as strategic energy management plan for this airport. In conclusion recommendations were made on how to reduce energy consumption, also renewable energy should be incorporated into the airport power system so as to reduce carbon emission at point of generation.
