Abstract: This Study aims to decrease energy consumption resulted from thermal comfort demand in single façade residential buildings. Depending on changing two main parameters, namely, street canyon ratio (H/W) and skylight height, a validated computational fluid dynamic (CFD) steadystate K epsilon turbulence model has been performed for the main eight orientations (N,NE,E,SE,S,SW,W,NW). This process resulted in a tool which can be used as a decision framework for improving indoor thermal comfort taking into account the energy consumption. Cairo city has been used as a case study as it is considered one of the top densely populated cities in the world. So, adjacent buildings with one façade are widely spread. Hence, these buildings' inward rooms are lit and ventilated using open skylights. Street canyons with high ratios (H/W) are existed. Consequently, high amounts of energy consumption are spent in indoor thermal comfort and air quality.
