Abstract

Despite growing design demand, there has been little research on the design of shading devices for the outdoor environment. Heat-related illnesses are becoming a more pressing issue as temperatures rise due to climate change. Seeking shade is one effective way for humans to protect themselves. Blocking sun radiation is the main goal of shading. One of the most effective cooling strategies, found in nature, is the tree fractal strategy used to optimize shading. Similarly, Girih patterns are fractal in geometry. The purpose of this paper is to design a shading device based on the Girih fractal geometry inspired by tree concepts. Then employ the Islamic Girih fractal geometric patterns through their repeated units in a contemporary design with advanced tools. Thus, achieving significant contrast of solids and shapes against light and shade in contemporary designs. Two models of the same structure and different density were designed, then their shading data were evaluated and compared. This was done by using field measurements to estimate the impact of each shading strategy on thermal comfort during sunny days. The study is conducted in Cairo Egypt and the major goal is to improve users' thermal comfort as well as reflect on local social identity and distinctiveness.
