Effectiveness of Energy Retrofit on Energy Consumption and Occupants' Comfort: Case of Shahid Beheshti University Dorimitories

In addition to the building properties effect on energy consumption, it is important to consider occupant’s energy behavior and their interaction with building systems in energy calculations. According to studies, energy retrofit regardless of considering this factor, has a lower effect on reducing the energy consumption. This study investigates the impact of energy retrofit in two (retrofitted and non-retrofitted) university dormitories, on occupants’ comfort and the buildings’ energy consumption. Research methodology is based on filed studies and dynamic simulations. The results of filed studies showed that, the implemented improvements have minor effects on occupant’s comfort inside the building. Simulations also indicates that despite of 63% reduction of energy consumption in the new building, discomfort hours have increased 9.5%, compared to the other studied case.
