Abstract: This paper mainly focused on a method against building daylighting design, emphasized on the dayligting analysis under the regional daylight climate and the comparisons between design schemes utilized the parametric model, the procedures ensured an optimized design scheme would be generated. A given Guangzhou based building project was selected as the example to discuss the improvements that shading facilities should bring to the interior daylight environment, the design progress could concluded as: To achieve an optimized daylight environment, an effective comparisons between design schemes were conducted using the parametric building model, finally, a daylighting design scheme was generated meanwhile preserved the functionality of shading. According to the previous study, all the daylighting simulations related works in this paper was conducted under the representative sky model (CSRS) which could represent the local daylight climate.

Key words: daylight, shading, representative sky, parametric model

摘要： 文章阐述了一种建筑采光设计方法，重点强调了在地域性光气候条件下的采光分析以及利用参数化模型进行采光方案的比对，以上过程保证了优化方案的获得。文中以位于广州市的某给定的建筑项目为例探讨了建筑侧窗遮阳构件可能给室内采光带来的改善，设计过程可概括为：以优化的自然光环境的优化为目标，利用参数化模型技术对于方案进行了高效的择优，最终得出了兼顾遮阳效果的采光设计方案。基于课题组前提的研究成果，文章涉及的采光模拟工作均在可反映广州地区地域性光气候特征的典型天空亮度模型（CSRS）的基础上进行。
