This paper studies the shape design strategy of underground atriums in cold regions based on climate adaptability. From the perspective of climate adaptability, by controlling the shape design parameters of the atrium, and taking the light and thermal performance of the underground atrium as the optimization goal, the light and heat performance simulation and multi-objective optimization are constructed. Method, analyzing the effect relationship of various shape parameters on the light and heat environment and exploring the shape scheme of the underground atrium suitable for cold regions. And it is hoped that architects can take into account the quality of the light and heat environment of the underground atrium in architectural design and use space adjustment to improve the awareness of the quality of the light and heat environment of the underground atrium. The simulation results show that the annual PMV thermal comfort time percentage is 20.47%, the heat radiation difference RAD in summer and winter is 21.17 kw center dot w/m2, and the average percentage of natural lighting is 67.41%.
