dc.description.abstractOver the years, the need for energy efficient building is on the increase as the current practice of building trends consumes a lot of energy. Buildings such as hotels consume a lot of electricity in providing comfort to the occupants through mechanical cooling. The most effective way of reducing cooling load is by reducing the solar heat gained by the building. External shading device are efficient in reducing cooling load when properly designed. The study aims to improve cooling efficiency by assessing shading device strategies with different variables. The variables that are considered in this are the horizontal shading device on the north and south orientation, the distance of shading device from wall and angle of shading device in the area of study in the hot -dry climate.The based case was modeled in Autodesk Revit and simulated using the Autodesk simulation Computational Fluid Dynamics (CFD). Autodesk simulation CFD assess for natural ventilation using indicators such as Predicted Mean Vote (PMV), Percentage Persons Dissatisfaction (PPD) and temperature. The result for the based cased model was +2.4(warm) of the PMV, 78% of PPD and the temperature of 32.01°C. While the concrete shading device at an angle of 70° with no distance from the wall on the north and south proved more comfortable over the other shading device strategies with a PMV of +0.2 (slightly neutral) and a PPD of 15% which is satisfactory, with a temperature of 27.01°C. In conclusion, the study discourages the use of 90° angle shading device with 200mm from wall with a PMV of +2.4 and a PPD of 80%, which has high discomfort level in the space. The 70° with no distance from the wall has shown significant improvement of natural ventilation and a 5°C reduction in temperature.en_US
