| Abstract :- The object of this paper is to find the relationship between slop angle, orientation for inclination roofs which used in frame building (steel & concrete) in Baghdad city. (Latitude 33.3º North), and it's effect on the solar heat gain value which transferred through that roofs and it's effect on the electrical power consumption for summer cooling purpose. The researcher is build (1 x 1 x 1)m frame building sample, it’s roof is rotated horizontally eight times and is made by two parts, first part is called frontal part (it’s slop angle would vary from 5° to 45°), the second part is called rear part (it’s slop angle would vary from 90° to 5°). Finally , the researcher was found the relationship between that angles will be taken the following form : If frontal angle less than 20°, the minimum electrical energy was occur at North , North East and North-West, when rear angle is 20°, while , for East, West and East-South was occur at 10°, the another orientation at 5°. If frontal angle equal to 20°, the minimum electrical energy for cooling was occur at 5° rear angle for all orientation. If frontal angle more than 20°, the minimum electrical energy was occur for North & East North at 20° rear angle, while, for South orientation at 5°, while the other orientation was occur at 10° rear angle. And also, can notice that the roofs 20° frontal angle & 10° rear angle is consuming lowest energy for cooling with all orientation . | ||
