Hospitals are known to be one of the largest energy consumers as they continuously provide healthcare services to the community on a daily basis. This thesis reports a case study carried in one of the public hospitals in Malaysia - Hospital Kajang, as an effort to gather and disseminate more information regarding energy efficiency opportunities in hospitals which will benefit the hospital management as well as the public. The study was carried out via walk-through audit and desktop analysis, followed by a detailed energy audit to identify the electrical energy consumption pattern, factors that affect the energy usage and end-use energy analysis based on different categories namely air conditioning and mechanical ventilation system, lighting system, medical equipment, IT equipment and peripherals and other electrical equipment. Malaysian Standard MS 1525:2019 was used in this study for evaluating the indoor environment quality as well as lighting to ensure energy efficiency will not affect these requirements. From the study, it was found that the largest electrical energy end-user in Hospital Kajang is the air conditioning and mechanical ventilation system, which consumes approximately 78% of the total electrical energy. The building energy index calculation revealed that the hospital building has an index of 302.32 kWh/m2/year for the year 2019 which is significantly higher than the benchmark value of 200 kWh/m2/year for office buildings. A number of energy efficiency measures were proposed to reduce energy consumption in Hospital Kajang, together with their respective economic analysis.
