The paper used thermal environment simulation software used for design solar greenhouse to predict the indoor thermal environment of 12 kinds of solar greenhouse walls of different types under weather conditions of Shouguang, Beijing and Kezhou.The heat storage capacity of various typical north walls were analyzed and advantages and disadvantages were assessed with heat released at night and indoor air temperature as indicators.Heat storage capacity of Shandong soil wall was the best.Heat release at night increased significantly as the thickness increased from 1.5 m to 3.0m, but only gradually from 3.0 m to 5.0 m;however indoor air temperature difference between different constructions was not large.The best heat preservation and storage capability of Beijings composite walls was achieved in construction of 400 mm aerated concrete masonry and 100 mm polystyrene and 200 mm aerated concrete masonry on the outside.Heat preservation and storage capability was the best with 250 mm Gobi crushed stone concrete and 1500 mm Gobi sandy soil stacks from the inside out, and the cost was reduced by utilizing local materials in Xinjiang.Different regions should choose building materials which have good heat preservation and storage capability in light of local conditions to design reasonable structures.
