The maximum energy use intensity in block D is observed in January (Fig. 6). Obviously, space heat and ventilation fans have the highest share among other parameters. Accordingly, the highest level of energy consumption based on energy cost is seen in July and August and based on energy use intensity is seen in January and December. The schematic diagrams of energy consumption for block C and the western lobby are similar.The results show that block D has the lowest energy consumption after optimization. Based on the parameters presented in Table 8, the cost of energy consumption for block C is 13.6 USD/m2/y. This value for both block D and the western lobby is 14.1. Accordingly, the energy use intensity for blocks C, D, and the western lobby would be 126, 119, and 191 kWh/m2/y, respectively (Table 10). The building orientation, in this case, is based on the geographical north. Thus, angle of the building is automatically determined by the software, based on the building form and the project geographic coordinates. The windows ratios to the northern, southern, eastern and western walls are 21%, 23%, 7%, and 8%, respectively. These values are 21%, 21%, 5%, and 10% for block D, and 15, 25, 13, and 14% for the western lobby, respectively. The shades of all windows are considered by default. Therefore, the windows installed on the terraces would use their overhead ceiling as a shade. Other windows installed
