In hospitals, the issue of energy conservation, indoor climate control, and air conditioning is of particular importance, due to the high complexity and strict considerations in terms of comfort and safety. Hence, energy performance evaluation and energy efficiency measures for hospital departments are more complex compared to other buildings. In this study, the energy system of a hospital has been modeled using Design-Builder software and the results have been validated by the hospital's energy bills. Then, several scenarios have been proposed in order to reduce the energy demand for heating or cooling and improve the efficiency of primary energy systems. The amount of energy conservation in each scenario has been estimated. Ghiasi Hospital, located in the southwest of Tehran, was selected as the case study. Based on the modeling step, the current energy system of the hospital consumes 3.08 GWh of electricity and 4.23 GWh of gas annually. Adding a thermal recovery system can reduce the gas consumption of the system by 30%. On the other hand, improving the lighting system can save 22% in electricity consumption.
