In order to improve the air pollution caused by farmers’ treatment of crop by-products in the cold north, the energy saving and thermal insulation properties of improved straw brick buildings are studied. Firstly, the main process of building a house with straw brick and improved straw brick made of straw stalk is introduced, and a thermal performance calculation model based on the heat exchange principle of the wall is built. Then, the thermal load performance test parameters of ordinary brick and improved straw brick are introduced. Finally, the thermal load calculation results of ordinary brick and improved straw brick are compared and analyzed. The results show that in terms of economic efficiency, compared with ordinary brick, straw brick house not only has a wide range of sources but also has simple process of production, so it has a better economic efficiency; in terms of environmental protection, the production of straw brick houses, compared with ordinary bricks, will not emit emissions and is an environmentally friendly raw material; in terms of energy consumption, the insulation of straw brick can well regulate the indoor and outdoor environment and effectively reduce the heat loss. This study provides a good theoretical basis for popularizing the use of improved straw bricks.
