Selection Method of Light Shelf System for Mountainous Residence:A Case Study of Liziba Area
With the influence of complex terrain,mountain buildings generally have the problem of insufficient lighting,and it is common practice to use a lighting improvement system to improve the indoor light environment.In order to explore the selection method of lighting systems for mountainous buildings under different topographic relationships,this paper,with the residential buildings in Liziba district of Chongqing as an example,selected orientation,floor,spacing,height of retaining wall,and length of retaining wall as variables to conduct simulation calculation and data analysis.The results of the orthogonal experiment and Pearson correlation analysis show that the ratio"D/H"of the distance between the lighting surface and the retaining wall to the height of the retaining wall can better reflect the lighting characteristics of each layer in buildings under different topographic environments.Based on this,this paper proposed a set of methods to quickly select suitable shading and daylighting systems for mountain buildings based on"D/H"index,and verified its effects.
