Discussion on applying trombe wall technology for wall conservation and energy saving in modern historic buildings

摘要

Previous studies on modern historic buildings protection have been mainly conducted from the view of building history, culture and aesthetic, but rarely focus on the green building technology and energy-saving. With the increasingly serious crises of environment and energy, it is valuable to research how to carry out ecological protection to effectively reduce energy consumption in modern buildings while ensuring the authenticity and readability of building heritage information. This article describes a new technical scheme to apply Trombe wall technology for wall conservation in modern historic buildings. The feasibility, key construction technologies and operating conditions in different seasons were demonstrated by an actual case in Beijing. Key findings show that the technical scheme not only protects the skin texture of the wall but also makes full use of passive solar energy. Energy consumption simulation results show that saving energy in winter is significant. Compared with the original building, the total energy consumption of the building that adopted the technical scheme was reduced by 10.77%, the heating energy consumption was reduced by 21.86%, and the cooling energy consumption was reduced by 1.02%. The research findings provide new inspiration and reference for studies on the protection of modern historic buildings, and serve as a technical reference for architects.
