建筑防热与室外热环境理论研究

This project has studied the theory of building shape design for solar heat control and evaluation of outdoor thermal environment，as well as ecology thermal effect of green space. An optimum method of building shape design for solar heat control is proposed. The calculate result shows that more than 20% direct solar radiation on the external surface of building can be decreased by the optimum method. Combination the optimum method with traditional technique for solar heat control and environment design，energy used for cooling can be decreased and thermal environment around building can be improved. Based on PMV-index which is used to evaluate indoor thermal comfortable, a thermal index is proposed to evaluate outdoor thermal comfortable. This thermal index with Wet Bubble Globe Temperature index (WBGT) can be used to evaluate outdoor thermal environment for all cases. Ecology thermal effect of green space on urban environment has been studied and some news are obtained in this project.

面对夏季空调能耗巨增、室外热环境污染日益严重的状况，本项目以可持续发展的观点研究绿色建筑防热设计理论。研究内容为：1.建筑方案的防热设计理论；2.外墙反射隔热与室外热环境设计理论。通过房屋规划、建筑技术、环境规划的有机结合，有组织地把照射到建筑外表面的太阳辐射热引向生态系统的良性循环中化解，达到节能和改善室内、外热环境的目的。
