Evaluation of the energy consumption mechanism based on urban street orientation

Lack of due attention to the orientation of streets and establishment of urban blocks without regard for climatic characteristics and conditions of the environment have an adverse effect on thermal comfort in open urban spaces. Construction of new settlements without taking any study of climatic requirements undermines thermal comfort for pedestrians and other users, especially in cold regions. Considering the conditions of Khorramshahr city and also its specific climate, the study of the subject of energy as well as the explanation of general and structural principles for future changes need to be studied and evaluated in a sustainable manner. For this purpose, microclimate simulation was performed using ENVI-met software. A sample parcel with six different orientations (With a distance of 30 degrees) were simulated in the hottest day and the sultriest day of year. The results suggest that the orientation mode of the passages at 30 degrees from the north is the best mode resulting from the simulation and compared to the higher modes, the micro- climatic conditions are better and more favorable. Orientation of 60-degree passages is also known to be the worst-case scenario. The final result of this section represents the order of priority orientation of the main thoroughfares for the future development of Khorramshahr city. By using the results of this section in order to select and use the optimal orientation for the passages, as well as molds with optimal shape and density, we will definitely see very visible and tangible results in the short, medium and long term and for the next researches, other approaches of evaluation in micro scale can be done.
