摘要
本文以北京某超低能耗幼儿园为例研究了自适应照明与活动外遮阳的综合影响。研究中照明设置了2种工况,其一为根据工作作息运行的标准工况,其二为自适应照明系统。活动外遮阳产品形式研究了遮阳卷帘、固定角度的百叶和可根据太阳角度自动调整角度的百叶。结果表明,在所研究的案例建筑中,自适应照明系统的节能贡献比较高,优于活动外遮阳节能贡献。在超低能耗公共建筑遮阳设计中,不应忽视遮阳对照明能耗的影响,而应优先考虑遮阳但不增加照明负荷的遮阳产品形式,并应进行综合节能潜力与投资经济性分析。
This paper took an ultra-low energy consumption kindergarten in Beijing as an example to study the comprehensive impact of adaptive lighting and movable external sunshades.In the study,two working conditions were set for lighting,one is a standard working condition that lighting operates according to a fixed schedule,and the other is an adaptive lighting system.Three types of external movable sunshades were studied,including the roller curtain,fixed-angle louver,and the automatic solar tracker louver.The results indicated that the adaptive lighting system has more energy-saving contribution than the movable external sunshade in the studied case.In the sunshade design of ultra-low energy public buildings,the effect of shading on lighting energy consumption should not be neglected.Priority should be given to the form of shading products that does not increase lighting loads,and energy saving potential and economic analysis should be taken before the scheme is confirmed.
