A new type of temporary building with a mouth-shaped layout was proposed to improve the current situation of excessive energy consumption in temporary buildings in alpine regions.Taking Lhasa region as an example,the degree of influence of three different layouts on the building load are simulated and analyzed with DeST dynamically,to find out the optimal design of temporary buildings adapted to the alpine climate.It was concluded that the new mouth-shaped building layout with sun heated shed had greater advantages in energy saving and can make the room load distribution in the building more uniform and improve thermal comfort.In addition,through the analysis of the thermal parameters of the building envelope with the mouth-shaped layout,it was found that the optimal thickness of the roof insulation layer of the dormitory was 160 mm,the optimal thickness of the ground insulation layer was 150 mm,and the optimal insulation layer of the building exterior wall was 110 mm.Further simulating the effect of aspect ratio on loads in mouth-shaped layout,it was found that the cumulative annual heat load of the building decreased significantly as the aspect ratio increased.
