As the largest envelope of a building、 the exterior wall has great potential in energy-saving design. In the design of passive solar houses、 the outer wall is designed as a heat collector (or heat sink)、 combined with the utilization of solar energy. An air replacement layer is installed on the middle and outer walls to achieve the comprehensive insulation and energy-saving effect of the wall. In order to implement the national energy-saving policy and improve the situation of high heating energy consumption and poor thermal efficiency in residential buildings in severe and cold regions、 it is necessary to save energy through building design and construction measures. The energy-saving design of walls as a maintenance structure is of great significance for the low energy consumption of the entire building. The country has also introduced a series of technical measures related to wall energy conservation to regulate this field P>
