The cost of the building envelope is generally increased to only 3% -6% of the total investment, and the energy is saved by 20% -40%. By improving the thermal performance of the building envelope structure, the outdoor heat can be reduced to be transmitted into the room in summer, and the loss of the indoor heat can be reduced in winter, so that the thermal environment of the building is improved, and the cold and heat consumption of the building is reduced. Firstly, the thermal performance of each component of the building envelope is improved, and the thermal performance is generally realized by changing the thermal performance of the component materials, such as a thermal diode wall (a low-cost thin thermal diode only allows one-way heat transfer and can generate a heat insulation effect) newly developed by the european union and glass with the thermal performance dynamically changing with seasons. And then, selecting an envelope combination optimization design method according to the local climate, the geographical position and the orientation of the building by taking the calculation result of the building energy consumption software DOE-2.0 as guidance. And finally, evaluating the technical and economic feasibility of each part and combination of the building envelope to determine the building envelope which is feasible, economic and reasonable in technology.
