ASSESSMENT OF ENERGY PERFORMANCE BASED ON ENERGY AUDIT OF A HOTEL USING EXERGY APPROACH

This study presents an analytic assessment method of energy consumption processes that was developed to apply to the energy management systems of hotels. This method has based directly on an exergetic approach and examined energy and environmental performances using energy and exergy analysis with the pre-energy audit. The energy efficiency performance of the hotel was considered for uninsulated (Case I) and insulated (Case II) conditions. The results of the analysis show that energy consumption losses are related to not only the structural features of the buildings but also the operational management of the hotels. Also, the specific energy consumption of Case II is 43,08% higher than the Case I. Exergetic efficiency for insulated and uninsulated conditions were found as 27.31% and16.26%, respectively. At the end of the study, some recommendations on effective energy management and the applications of a hotel were revealed.
