Simulation of indoor thermal energy cycle in green building VR design based on BIM and computer virtual vision

With the increasing awareness of global climate change and environmental protection, the design concept of green buildings is gradually being valued. This study aims to explore the application of indoor thermal energy cycling based on Building Information Modeling (BIM) and Virtual Reality (VR) technology in green building design, with a focus on analyzing the impact of thermal cycling processes on energy conservation and thermal comfort. This article summarizes relevant work, clarifies the carbon footprint calculation method for green buildings, including carbon source analysis in the design and operation processes, constructs a detailed thermal energy cycle model, and elaborates on the basic principles of solar thermal storage systems. By utilizing BIM technology, this article has achieved virtual design and simulation of green buildings and explored the optimization effect of indoor thermal cycling. The research results indicate that appropriate thermal cycle design can significantly improve indoor thermal comfort and, through effective calculation of comfort zones, achieve quantitative evaluation of energy-saving quality. Through VR design simulation, users can intuitively feel the thermal comfort performance of building design and its contribution to the environment, thereby promoting the realization of green buildings in practice. This article emphasizes the importance of optimizing indoor thermal energy cycle for green building design and points out future research directions that will help further enhance the sustainability and environmental friendliness of buildings.
