THE IMPACT OF RESIDENTIAL BUILDING’S DESIGN ON THE ENERGY CONSUMPTION IN HOT DESERT CLIMATE (BAGHDAD CITY AS AN EXAMPLE)

Residential Buildings are responsible for a large portion of energy consumption in cities. The study of The Impact of Residential Building's Design on the energy consumption in hot desert climate requires careful examination and evaluating the validity of the commonly known assumptions and for quantifying the effects of building design on energy consumption. This research problem is the effect of residential building design on the energy consumption in hot Deseret climate for Baghdad city as an example. In this study several options for residential building forms, area, number of stories, and walls materials were selected for the assessment of energy consumption. Software simulation was to estimate an energy performance model for assessing various energy conservation measures pertinent to the building design. Percentage change was calculated and compared accordingly for each case. Results demonstrate that shapes with less surface area achieved better results. Also for wall materials the reduction reached to 50% for Thermostone wall for the same building form and area. The area of building and number of stories contributes on energy consumption too. Building with less area provides better results. Also buildings with two stories provide total energy consumption for average square meter less than on story building
