Abstract

An experimental study has been carried out to investigate how much energy may be saved through the use of thermal insulation in the walls and roofs of buildings, experimental tests were done to show percentage of saving energy in walls and roofs. The experimental result shows that the maximum energy saving for the walls when using Rockwool as insulation is75.1% but when using of extruding polystyrene (XPS), it is 73.9%. Similarly, for the roof the results are 66.6% and 61.1% respectively. A theoretical method based on annual energy saving using Degree-Day Method, has been employed for Erbil city. The percentage of energy saving using Rockwool, in case of walls is 77.9% for heating, and it is 78% for cooling. In the similar manner the percentage of energy saving for Erbil city is 77.3% for heating, and cooling when using xps, in case of walls but for the roofs the percentage of energy saving is 80.5%  for heating  and cooling when using rock wool and 80.1% when using XPS.
