摘要：

An energy-efficient design can be achieved mainly through accurate design of built -environment forms. This paper aims to investigate the effects of urban block forms on natural ventilation patterns in the Sanayee neighborhood in Tehran, thereby potentially having air pollution, using computational fluid dynamics (CFD) analysis. The wind pressure and speed indicators were measured by ANSYS Fluent software, using standard k-epsilon model. The results showed that two factors with the most effect on wind pressure difference were urban block height and widths of adjunct roads. As a result, natural ventilation and consequently energy consumption were affected. (C) 2017 The Authors. Published by Elsevier Ltd.
