The Effect of Various Types of Building Roof Materials on the Cooling Load

Building information modeling took great interest in recent years in the world in terms of the design simulation of the buildings and chooses the best design. Therefore, roof insulation is one of the most important strategies to reduce the electricity consumption in the building which leading cost savings and reduce the emission of gases that pollute the environment directly. This study aimed to evaluate the effect of various types of building roof materials on the cooling load. This study involved in selecting a particular building type (factory building) and the effect of the cooling load by using a various metal deck roofing with and without insulation. The cooling load requirement for the building was calculated by using Auto desk Revit software. The results indicated that roof insulation is one of the most important strategies to reduce the cooling load and enhanced the electricity consumption in the building. The twenty percent reduction in the space cooling leading cost savings and reduce the emission of gases that pollute the environment directly. The study proved that polystyrene foam better than polyurethane foam and polyethylene, where the rate to reduce the cooling loads higher by about 9 % from polyurethane foam and 17 % from polyethylene.
