摘　　要：良好的采光设计策略需同时考虑对光环境和建筑能耗的影响,而以图书馆阅览空间为代表,具有较高采光需求的功能空间则往往面临采光与能耗的权衡难题,寒冷地区因需兼顾采暖制冷更甚。与此同时,当代公共建筑的自身立面形态设计加剧了这一问题的复杂性。以西安地区图书馆南向阅览空间为原型,利用DesignBuilder软件对寒冷地区不同外立面形态变化阅览空间的采光和能耗影响进行了综合模拟分析。结合图示相关性分析,统计光热性能结果,并基于优化阅览空间采光效果同时控制建筑能耗增加的综合目标,提出了窗墙协同变化类型的外立面优化设计建议。结果表明,针对阅览空间外立面形态设计,考虑竖向形态变化设计时可选择旋转角适中偏小(0°~15°)的竖向旋转式;考虑水平向形态变化设计时可选择旋转角较小(0°~5°)的整体偏转式或旋转角设置较为灵活(-25°~5°、15°~20°)的单元偏转式。A good daylighting design strategy needs to consider both the influence on the daylight environment and building energy consumption.The functional space with higher daylighting requirements represented by the library reading space often faces the balance between daylighting and energy consumption,and it is more difficult in cold climate area because it also needs to consider heating and cooling.Meanwhile,the design of contemporary public buildings’facade forms aggravates the complexity of this problem.Taking the southward reading space of the library in Xi’an as the prototype,the DesignBuilder is applied to comprehensively simulate and analyze the influence of daylighting and energy consumption on the reading space of different facades in cold climate area.Combined with the analysis of correlation by the photograph and make statistics on the results of daylight and energy performance,the comprehensive objective of optimizing the daylighting effect of reading space and controlling the increase of building energy consumption,the optimization design of facade with windows and wall collaborative change type was proposed.The results show that for the design of the facade of the reading space,when considering the change of vertical shape,the vertical rotation form with moderate or small rotation angle(0°~15°)can be selected.While considering the horizontal morphological changes,the entire rotation form with small rotation angle(0°~5°)or the unit rotation form with flexible rotation angle(-25°~5°or 15°~20°)can be selected.
