杭州市武林广场地下空间采光分析

Daylight Analysis of Underground Space of Wulin Square in Hangzhou

地下空间的物理环境是当前建筑物理环境的主要研究对象之一。以杭州武林广场地下空间开发为例,重点分析设计思路与物理环境之间的契合点。选取武林广场地下空间开发的局部空间作为研究对象,以光环境效果为研究内容,分析下沉广场为地下空间引入的天然光效果,同时也为下沉广场等改善物理环境的设计手法提供设计依据。研究表明下沉广场不仅使自然光从上至下得到了延续,而且不同节气、天空模型对室内的光照度以及亮度分布有不同的反映。这为改善地下商业空间的光环境、提高人体舒适度创造了有利条件。同时,为地下空间与物理环境的良好结合提供一定的指导作用。

Physical environment of underground space is currently one of the main objects in the field of building physical environment.In this paper,Wulin square underground space of Hangzhou was used as the meeting point of design idea and physical environment.The part of underground space in Wulin squarewas seen as major object,and the role of daylight introduced to underground is analyzed.The purpose of this research is to know about the effect of daylight in the underground space,then provide the design evidence for many physical measures like sunken square.The conclusion shows that Sunken square not only makes the daylight pour from the top to the bottom continuously,but also different Solar Term and Sky Model can result in various illuminance and luminance distribution.Then it makes the beneficial condition for lighting environment and personal comfort improvement of underground space.Meanwhile,better combination between the underground space and physical environment can be inspired.
