Reconsidering the Egyptian building code with regard to street widths and their impact on the daylight quality inside residential spaces

This paper presents recommended considerations in Egyptian building code 119 of 2008 (officially the Unified Building Law no. 119 of the year 2008) for achieving optimum day lighting in residential spaces by comparative analysis methodology of the Egyptian building code with the Indian and Californian building codes. The paper identifies the shortcomings and the gaps in the Egyptian code regarding natural lighting which does not consider the influence of land planning elements on the quality of interior daylighting e.g. different street widths surrounding the building and their relationship to the building height.
