Abstract :In this study, a simplified equation to estimate the space cooling load was developed as a function of solar time by taking into account the properties and the plan of the building on the base of the basic equations of heat transfer, thermodynamics and solar engineering. Therefore, tedious look-up tables were eliminated. This method enables to find out the effect of the thermal capacity of a building, the shades, thermal and optical properties, orientations and dimensions of the building on the cooling loads, besides the peak cooling load with the exact time. The shaded areas on the four walls are calculated as a function of solar time. The effect of three types of prevalent shading on the peak cooling load and the daily cooling energy demand are calculated and demonstrated for all orientations of the building. The height of neighboring buildings, the width of the roads around the building, the extension of roof overhang and the open double roof are also taken into consideration.
Keywords : Cooling load, Solar radiation, Glazing, Shading, Orientation and absorbance
