Indoor thermal energy optimization and 3D visualization based on ambient light sensing in the protection of historical architectural landscapes

While preserving cultural heritage, historic buildings also face the challenge of modern comfort and energy efficiency. Thermal energy optimization of indoor environment is an important means to improve living comfort and reduce energy consumption. Especially when protecting historical buildings, it is necessary to analyze how to carry out effective thermal energy management without affecting their appearance and structure. This paper discusses the optimization strategy of indoor thermal energy based on ambient light sensing technology, combined with 3D visualization to achieve the balance between energy conservation and comfort in historic buildings. Through the dynamic monitoring and analysis of indoor thermal environment, a feasible solution is provided for the protection and utilization of historical buildings. In this study, ambient light sensors were deployed in a historical building to monitor indoor light, temperature and humidity in real time. Through data collection and analysis, the main factors affecting indoor thermal environment are identified. 3D visualization technology is used to visualize the indoor heat energy distribution, and specific optimization suggestions are put forward. The research shows that the application of ambient light sensor significantly improves the monitoring accuracy of indoor heat energy, and the implementation of optimization measures reduces the indoor temperature fluctuation and energy consumption. The 3D visualization visually shows the thermal energy changes before and after optimization, providing a basis for managers to make decisions. Combined with 3D visualization technology, it not only enhances the comprehensibility of data, but also provides innovative ideas for the protection and rational use of historical buildings.
