In order to explore the problems existing in building energy saving of autoclaved aerated concrete block,the thermal performance of autoclaved aerated concrete block wall is studied by AIRPAK software in this paper.Through modeling research on the ash joint of B04 autoclaved aerated concrete block wall with different thickness of 300 mm,the change of heat transfer co-efficient of autoclaved aerated concrete block wall with different ash joint thickness and the influence of ash joint on heat transfer coefficient of wall with 25 mm and 50 mm graphite polystyrene board pasted on the outside of wall are discussed.The results show that when the thickness of the ash joint is 8-15 mm,the increase ratio of the heat transfer coefficient of the wall is 15.152％～31.313％,and the influence of the ash joint on the heat transfer of the wall cannot be ignored in the calculation of building thermal engineering.;With the increase of the thickness of the insulation layer,the influence of the ash joint on the heat transfer coefficient decreases gradually,but it can not be ignored;When the thickness of insulation layer is 25 mm and 50 mm,the increase ratio of heat transfer coefficient is 6.584％～15.265％and 4.231％～21.154％.
