BIM to BEM Transition for Optimizing Envelope Design Selection to Enhance Building Energy Efficiency and Cost-Effectiveness

Abstract

This article focuses on developing an energy simulation model through Building Information Modeling (BIM) and Building Energy Modeling (BEM)to optimize energy in building design in Vietnam. Reducing the energy consumption in buildings will help reduce operating costs, impact the environment, and increase the efficiency of buildings. However, there is limited research on buildings with complex structures and configurations, detailed surface design, and envelope construction, especially in simulating details through BIM. The author proposes converting from BIM to BEM to simulate energy in buildings and optimize the factors related to building construction in the envelope design of the building. These factors include wall cladding materials, mirror materials, the window ratio on the walls, and other details. This study has effectively created an energy model for a public building, allowing for the calculation of the Energy Intensity Index (EUI) and annual energy costs for various scenarios. By altering factors associated with the design and construction process, the system has the potential to decrease both energy intensity and usage costs for the building. The study results will help designers and building managers improve and enhance energy efficiency in building projects.

“…Insight also suggests optimizations in both window design (to improve and take advantage of sunlight and natural light) and in the use of electronic devices to take advantage of low electricity consumption in terms of schedules and the natural lighting of the building spaces. In addition to using photovoltaic panels, the program suggests the orientation and number of devices for the building's consumption as developed [51]. The above is suitable for optimizing the model and conducting comparative studies between different developments and their uses.…”

“…The above is suitable for optimizing the model and conducting comparative studies between different developments and their uses. However, for this study, only the energy consumption of the models is necessary for subsequent analysis derived from the materials used, which was also developed by [51,52].…”

“…This collaborative method increases efficiency, minimizes errors, and improves project outcomes in budget management, adherence to timelines, and quality assurance. According to [13], BIM usage also enables project teams to explore various design options through simulations and analysis. This empowers them to identify optimized solutions that align with project goals and minimize potential risks.…”
