Economic potential of energy conservation in a five star hotel

Abstract

Economic potential of energy conservation in a five star hotel was established. The selected site was the Hotel Lanka Oberoi, Colombo. The electrical energy demand and the thermal energy demand of the hotel were assessed using the results of an energy audit carried out in the Hotel by the Energy Conservation Fund (ECF). It was found that there are several energy conservation opportunities (ECOs) for the Hotel.// Economic analysis was carried out for the six ECOs of VAV Systems, Low-e Glass Systems, Day lighting Control Systems, Energy Efficient Lighting Systems, Indoor Temperature Set Up and Thermal Energy Storage Systems.// It showed that all the six ECOs are feasible with favorable economic parameters. Nevertheless there are merits and demerits among each of these ECOs and the sewer discussed with reference to each ECOs. Among the ECOs, VAV Systems and Energy Efficient Lighting Systems have the most favorable economic parameters with a payback period of 0.6 years and 0.2 years respectively.
