Abstract

Urbanization can lead to changes in urban morphology that alter the urban thermal environment and energy demand. Improving urban ventilation can alleviate the urban heat island effect and reduce urban energy demand. We categorized the ventilation conditions of 31 major cities in China into four levels based on the frontal area index and presented the natural ventilation effects for cities in five different climate zones. We found that the land surface temperature varies between 0.029 and 5.357 °C in areas under the same climate background. Improving ventilation can directly or indirectly contribute to reductions in urban energy consumption. The energy demand in well-ventilated areas can be reduced by up to 6.704%. The largest reduction in urban energy demand was achieved by improving ventilation within the temperate continental climate zone.
