摘　　要：为向建筑师构建用于设计初期阶段的建筑性能化设计方法,借助太阳能采暖效率计算方法来探索建筑热性能设计策略。论述了形体设计与建筑性能化设计的关系,提炼出影响建筑太阳能采暖性能的形体要素:高宽比、高长比、南向窗墙比。采用正交试验、动态能耗模拟、数理统计分析得到了基于建筑形体要素的建筑太阳能采暖效率的函数模型,通过实例验证了计算模型的有效性,应用该性能化方法优化了太阳能采暖的建筑形体设计,最后介绍了基于该方法开发的基于建筑信息模型(BIM)的建筑太阳能采暖潜力分析软件。研究探索了建筑设计初步阶段的性能化分析方法,为设计师提供设计策略灵活性和能耗强度变化规律的协同分析方法,完善了建筑绿色性能化设计体系建设。In order to construct the performance-based design method used by architects in the initial stage of design,the design strategy of building thermal performance with the calculation method of solar heating efficiency was explored.Taking the building height-to-width ratio,height-to-length ratio,and south-facing window-to-wall ratio as the building shape elements,the building solar heating potential function based on the building shape elements was obtained through orthogonal experiments,dynamic energy consumption simulation,and mathematical statistical analysis.After graphing the function,it was found that increasing the aspect ratio and the south-facing window-to-wall ratio could increase the solar heating potential of buildings.For the convenience of designers,a BIM-based building solar heating potential analysis software was developed and applied to actual projects.This research explored the performance-based analysis method at the preliminary stage of building design,provided designers with a collaborative analysis method for design strategy flexibility and energy consumption intensity change law,and improved the construction of a green performance-based design system for buildings.
