Evaluating the impact of shading devices, glazing systems, and building orientation on the energy consumption in educational spaces

This paper focused on the impact of the external shading devices, the optimal orientation, and the installation of Low-E glazing ‎systems on the energy requirements in a typical elementary school building for the hot-dry climate of Shiraz, a city located in the south of Iran. The study aimed to evaluate the effect of the parameters in the optimal design in terms of their thermal performance, in addition, to specify the parameter with the greatest outcome on the energy consumption decline of a prototype school in Shiraz. The results indicated that the modified de-sign can significantly reduce the annual energy loads of the school building up to ). Also, a comparative analysis among the three mentioned items showed that the shading device is more effective than the other two, which use simple horizontal and vertical shading devices in the northern and southern faces in order to decrease about 20% of the energy consumption
