摘　　要：自然采光是建筑的一项关键绿色性能指标,然而关于自然采光在建筑进深方向上衰减的相关研究相对稀缺,为建筑设计师提供的设计参考有限。以福建省建筑科学研究院总部大楼工程项目为例,运用ECOTECT软件进行自然采光模拟,并使用JTG01照度计进行实地检测,通过比对模拟与检测结果的差异来论证采光模拟的可信度;在建筑平面布局不变的情况下,基于不同可见光透射比的透明围护构件和不同可见光反射比的建筑内饰面,构建多种模拟工况,模拟得出了不同工况下大开间大进深房间的自然采光的平均采光系数分布,并分析自然采光与围护结构可见光透射比、内饰面可见光反射比的关系及采光系数的衰减与房间进深的关系,为建筑平面设计提供较为直观的参考。Natural daylighting is an important green performance indicator of buildings.However,there are relatively few related studies on the attenuation of natural daylighting in the depth direction of buildings,so there are limited reference for architects.Taking the headquarters building project of Fujian Academy of Building Research as an example,this paper conducts natural daylighting simulation using ECOTECT software and conducts field detection using JTG01 illuminance meter.The credibility of the daylighting simulation is demonstrated by comparing the differences between the simulation and detection results.Under the condition of unchanged building plane layout,different simulation working conditions are constructed based on transparent envelope components with different visible light transmittance and building interior surfaces with different visible light reflectance.The average daylighting coefficient distribution of large-span and large-depth rooms under different working conditions is simulated,and the relationship between natural daylighting and the visible light transmittance of the envelope structure,the visible light reflectance of the interior surface,and the relationship between the attenuation of the daylight factor and the room depth are analyzed,providing a more intuitive reference for building plane design.
