气凝胶玻璃住宅夏季室内光热环境研究与对策分析

Indoor light thermal environment and strategy analysis of aerogel glassresidential building in summer

以2018年中国国际太阳能十项全能竞赛为例,对某大学设计并建造的气凝胶住宅在方案设计阶段进行模拟,对建筑建成之后的室内温度及照度进行实测研究。结果表明:采用气凝胶玻璃外围护结构比采用木格构外围护结构的建筑能耗低26.06%,但应该采取有效的遮阳措施;采用气凝胶玻璃外围护结构的室内天然光照度大于300 lx,满足相关设计要求。针对此建筑因采用气凝胶玻璃而存在的问题提出改进措施,这对气凝胶玻璃的推广应用以及太阳能建筑的发展具有重要意义。

Taking the aerogel glass residential building designed and constructed in Solar Decathlon China 2018(SDC2018)as an example,this paper simulated the building in the design stage,and measured the indoor temperature and illumination after the building was built.The results show that the energy saving effect of aerogel glass was more significant than that of the wooden lattice envelope with 26.06%less energy consumption,but effective shading measures should be taken in summer.The indoor illumination of the aerogel glass room was greater than 300 lx,which met relevant design requirements.The improvement measures were put forward for the existing problems of this building,which was of great significance for the promotion and application of aerogel glass building.
