Airport Terminal has some unique architectural features, however, there is no design standard for Airport Terminal. In this paper, first, on the basis of researches and field tests, we make the dynamic load simulation using TRNSYS and analyze the characteristics of load of the Airport Terminal. We find the solar radiation has great impact on the building energy consumption. Second, we analyze the impact of sunshade and g-value on solar radiation. We find the L0 (L0=L/H) of southward should less than 0. 5, g-value should not be too small. Through this work, we hope to give a guide to the design of the Airport Terminal.
