Shading Effects on Reducing Annual Cooling Loads in Tehran Climate

چکیده مقاله

Buildings in Iran require large amounts of energy both for cooling and heating. This article has outlined the factors of shading louvers influencing cooling loads. With this in mind, a study is done on the thermal performance of a louver shading on office building in Tehran by simulation and different factors of shading models for windows was incorporated in our simple model. With the goal of achieving reduction of solar gain in summer; annual cooling and heating loads analysis has been done. In these simulations different factors are variable; these factors are louver’s material, number, angel, vertical space, depth and overlap. It was found that at first different factors has been studied to determine the most important factor of such systems in the Tehran region of Iran and secondly tried to decrease cooling loads in summer by decreasing solar gains.
