The passive priority can be achieved by building form derived from the simulation and analysis of wind environment,improvement of the building envelope insulation and the dehumidification of fresh air,the use of solar energy. The full life cycle utilization can be accomplished by the combination of exhibition and residents' leisure activities, and the integration with local cultural tradition, thereby improving energy efficiency and the utilization of the building.展开更多
