Effect of sides and back distances between buildings on the quantity of energy impact on building mass in urban fabric in Iraqi housing projects

This paper deals with the effect of inter-house distances in new cities on the thermal comfort inside houses, as well as the effect of increasing such distances on energy waste and the increase of dependency on air-conditioning and artificial aids. In this paper comparison has been done between the quantity of energy impact on separated houses and energy quantity impact of the same mass in urban fabric (-for housing projects having similar houses). The study has been carried out for case of attaching from three sides and for detached houses with inter-house distances between 2-8 meters. Results have been give for two cases, the first when streets are without trees and the second- when streets are planted with trees. The results were obtained by using computer program designed especially for this research. And is designed to be connected to Auto cAD (13) program.
