重庆地区绿色建筑导光管天然采光节能量研究——以龙兴生态城为例

Study on Energy Saving Amount of Natural Lighting by Lighting Pipe of Green Buildings in Chongqing

天然采光技术在绿色建筑中应用逐步扩大,应用于不同场所时,其节能效果不一。该文基于《建筑采光设计标准》提供的重庆地区导光管天然采光节能量核算方法,量化重庆地区办公室及地下车库的绿色建筑天然采光节能量。并基于重庆某地区绿色二星级项目,在设计中采用软件模拟分析技术优化地下车库导光设计,并对地下车库采用天然导光系统的天然采光节能量进行了分析,得出了以下结论:在重庆地区地下车库建筑中,可按8m×8m的间距设计直接采光导光管(Φ530),每平米导光管每年节约电能为1985.2k Wh。

Natural lighting technology is increasingly adopted in green buildings, and it has varied energy saving effects when adopted in different places. Based on the calculation method for energy saving amount of natural lighting pipe in Chongqing from Standard of Daylighting Design of Buildings, the energy saving amount of natural lighting of the green buildings like office buildings and underground garage in Chongqing is quantified. Simulation anal-ysis technique is applied in the lighting design optimization for the underground garage of a two-stared project in Chongqing to study the energy saving amount of natural lighting system of the underground garage. The study shows that spacing of 8＆#215;8m can be referenced in lighting pipe（？530）design in garage buildings in Chongqing, with yearly electric energy of 1985.2kWh saved of the lighting pipe each square meter.
