Integrating Shading Systems with Naturally Ventilated Double Skin Facades for Enhancing Thermal Performance in Hotel Buildings of Greater Cairo.

Abstract

The research aimed at evaluating the efficiency of integrating shading devices with naturally ventilated walls on thermal performance and indoor ventilation rates of a generic five stars hotel double room in Greater Cairo. This research is composed of 4 chapters. Chapter 1 and 2 studied theoretically and analytically naturally ventilated walls and shading devices’ working principle, types and how they work in hot arid climates. Also, the parameters of shading devices and naturally ventilated walls were discussed and some parameters were determined to be used in the comparative analysis which took place in chapters 3 and 4. In chapter 3, Cairo’s weather was analyzed and moreover a reference case was modeled and tested using Computational Fluid Dynamics simulations. In chapter 4 the results of three more cases were introduced and compared analytically. Those cases are: naturally ventilated wall case, and two cases of integration of shading devices with naturally ventilated wall one with shading devices near the outer skin and one near the inner skin.
