As a case study, energy analysis application of a hotel business in private sector

Abstract

In our study, a detailed energy study was carried out in a hotel business, which is a commercial building, energy saving potential was determined, measures that could be taken to increase energy efficiency and reduce energy consumption costs were determined and recommendations were presented. As a result of the measurements of the hot water installation line with the thermal camera, heat losses in the valves and flanges were observed and insulation was recommended. When the investment determined for insulation is made, it is calculated that there will be a decrease of approximately 17% in the annual energy consumption for the water installation. After heating, booster and fire pump motors with efficiency class EFF2 were replaced with IE4 efficiency motors, it is seen there is a 6.9% increase in motor efficiency. As a result of replacing the IE1 class engine used in the cooling system with an IE4 class engine, the engine efficiency is expected to increase by 6.2%. As a result of the replacement of halogen bulbs in the business with LED luminaires, the annual total electricity savings were calculated as approximately 19158.12 kW/year.
