At present, building energy consumption in my country accounts for about 1/3 of the total energy consumption. According to the latest data from the National Development and Reform Commission's energy projects, the energy consumption per unit area in my country is about 4-5 times that of developed countries for external walls and 2. 5 times, and the comfort is far less than that of others. The task of building energy conservation and emission reduction is still very arduous in our country, and there is still a lot of room for development. Although my country currently has increased requirements in terms of energy conservation and emission reduction, comfort is still ignored.

Hydrothermal sintering method (wet sintering method) does not destroy the inherent micro-pore structure of the soil, but can produce the required new micro-pores, so that the material has better thermal insulation and humidity control effects. This study simulates the thermal insulation and humidity control characteristics of cave soil, uses basic materials such as loess for hydrothermal curing synthesis, and prepares new intelligent air-conditioning building materials through the research and modification of the humidity control properties and formaldehyde adsorption properties of the hydrothermal curing materials.
