ABSTRACT

 

The study was performed at the Technical Services Business Unit of Air Mauritius and comprised of an energy and water audit to help the organization work towards an improved energy efficient framework. The main objectives of the energy and water audit were to indentify and quantify the energy and water flows within the organization together with the identification of the possible energy and water savings measures where losses and inefficiencies were concerned. Results reveal that The technical services department handles an average of 350 maintenance and repairs including checks every month thereby consuming around 176533 KWh of electricity. About 516 KWh of electrical energy is consumed per maintenance and repair. The other type of energy used at the TS department apart from electricity is fuel namely diesel and gasoline whereby diesel is used both for maintenance purposes and ground vehicles. However, maintenance and repairs consume much less diesel unlike ground vehicles. Water is consumed mainly for domestic purposes in the TS department and varied from 8804 m3 to 7984 m3 during the last three years. Areas where energy was being consumed inefficiently were identified. To avoid losses, some energy saving measures were proposed such as using more efficient tube lights and using air conditioning units with the proper cooling loads.
