天然采光影响因素分析与照明节能

A Study on Factors Affecting Building Daylighting and Analysis of Lighting Energy Savings

目前 ,国内天然采光的研究还局限于美学角度的考虑和定性分析 ,缺乏定量的计算和研究。本文利用RADIANCE软件 ,模拟计算了几个特性参数如窗墙比、窗台高、透光率、窗形等在进深方向对室内天然光分布的影响 ,并分析了天然采光所带来的照明节能状况。

At present, study on daylighting is only limited to the field of aesthetics and qualitative analysis instead of quantitative calculation and simulation in China. This paper provides a simulation on the effect of window to wall ratio(WWR), sill and transmittance and window configuration to indoor daylight distribution with the usage of radiance, and analyzes the lighting energy savings caused by daylighting.;
