Abstract :Many design parameters influence the energy demand of buildings. While research on building energy performance typically emphasizes physical design parameters and the technical characteristics of buildings, the behavior, actions, duration, and intensity of use by occupants are also critical factors impacting energy performance. Buildings should be constructed with functions aligned to the intended actions within spaces, ensuring user needs are considered during the design process. In this study, the variation in building energy performance was analyzed based on 9 different building functions and 3 climate types. Building energy models were developed using the BIM-BES methodology, and energy simulations were conducted using DesignBuilder software. The simulation results were analyzed through graphs, and energy performance characteristics were compared. Regression analyses were performed in Excel to explore the linear relationship between energy performance and occupant-related parameters, while correlation matrices were prepared and analyzed in Python. The findings revealed energy differences exceeding 80% due to variations in climate parameters and building functions. These results emphasize the critical importance of location-specific design and the integration of user needs during the design phase. This study highlights the necessity of user-centered approaches to improve building energy performance, supported by numerical data.
