Educational buildings in Iran , normally have short walls with large scale space and roof. Large scale roof as an external exposure part to sunlight or regions climate ,it can have a major role in receiving or wasting energy. Sunlight radiating on the roof is a key for absorbing heat in hot regions based on warmth intensity and time length lead to the warmer top floor and more expenses for cooling up the building. In this article ,the “cool roof” as a solution for controlling the roof heat absorbing and school’s roof refinements in hot regions also are included. This case study includes : representing the various cool roofs , its advantages and disadvantages in different regions and studying the of cool roof covering in schools all around the world. In addition , by evaluation the advantages and disadvantages of the cool roof covering in school buildings based on the construction condition , rebuilding condition and maintenance and relating expenses. The optimal and affordable cool roof suitable for Iran’s schools are recommended.
