The result displays that in the saving - energy building , the solar energy entering the room is far bigger than the heat load of the room . during the building design , should think about how to use the charge character of the pcm wallboard to utilize effectively this solar to reduce heating energy in the winter 结果表明在节能住宅建筑的南向房间,白天进入室内的太阳热量远远大于室内的热负荷,在建筑设计中可以考虑利用相变墙体的蓄热性能以更加有效的利用这部分热量,从而达到降低冬季采暖的能耗的目的。
Based on development background of building saving - energy technique of china , this paper introduces the newly research achievements on building saving - energy abroad , especially in the technique fields of the saving - energy design , the saving - energy material , the saving - energy equipment , the recycle of heat , waste heat and regeneration resources , and the saving - energy assessment 本文以中国城镇建筑节能技术发展为背景，从建筑物设计节能技术、建筑设备节能技术、热回收与废热及可再生能源利用技术、节能评价等方面，较系统介绍了国外建筑节能领域最新研究进展。
