摘要
对办公建筑的天然采光进行了实验研究。首先,从理论和模拟两个角度分析了模型和原型的照度分布相似性,并建立了办公室实验模型;其次,由于天空状态的多变性,提出用天然采光系数替代照度进行实验验证;最后,通过实验测试,分别验证了窗墙比、窗台高和透光率对室内照度分布的影响,分析了产生各种误差的原因,结果表明误差均在可接受范围内。
This paper provides an experimental study on day lighting of office buildings. Firstly, the illuminance distribution similarity of the model and ante type is validated with theoretical and simulating study, based on which the office model is established. Then, daylight factor is put forward to substitute illuminance for experimental analysis. Lastly, the study of the influence of window-to-wall ratio, sill high and transmittance on indoor illuminance distribution is carried out respectively with experimental test, and the reasons of testing difference are analyzed. The results show that the testing difference is acceptable.
