震前北川县居住建筑室内冬季阴冷潮湿、夏季闷热,室内热环境亟待改善。在灾后重建过程中,从建筑本体入手,通过改善围护结构热性能达到被动式调节室温的目的。基于当地实际情况,设定了合理的室内热环境改善目标及评价指标,通过模拟优化的方式得到了围护结构合理的热性能改善方案。 Before the earthquake, the indoor and outdoor buildings in Beichuan County were cold and humid in winter and hot in summer, and the indoor thermal environment should be improved urgently. In the process of post-disaster reconstruction, starting from the building body, the purpose of passive regulation of room temperature can be achieved by improving the thermal performance of the envelope. Based on the actual conditions in the area, a reasonable indoor thermal environment improvement target and evaluation index are set. The reasonable thermal performance improvement plan of the enclosure structure is obtained through the simulation and optimization.
