Shahid Beheshti University Advanced Environmental Sciences 3115-7173 12 4 2014 12 22 Comfort Evaluation in Urban Open Spaces Based on Wind Comfort Criteria,Case Study: Isfahan Comfort Evaluation in Urban Open Spaces Based on Wind Comfort Criteria,Case Study: Isfahan 97482 FA Seyed Hamidreza Rozati MSc. Student of Urban Design, Faculty of Architecture and Urbanism, Teacher Training Shahid Rajaee University, Tehran, Iran Abdolhamid Ghanbaran Assistant Professor, Faculty of Architecture and Urbanism, Shahid Rajaee Teacher training University, Tehran, Iran Journal Article 2015 09 12 Wind is one of the climate parameters that architecture and environmental designer have paid attention to itfrom past time till now. In some cases, wind flow in the urban open space is useful and it help to the natural ventilation and it causes improve human comfort and reduce energy consumption. On other hands in some cases wind flow causes reduce human comfort in urban open spaces. So in each climate architectures and other designer can decide how wind flow should control in the urban open spaces according to the wind comfort. In this article we want according to the Isfahan climate dates and statistical calculations and compared with wind comfort criteria, find the mount of the wind comfort criteria in the urban open spaces in Isfahan. So in this study three criteria consist of “Wind Chill Factor”, “Beaufort Factor” and “Penwarden Factor” was used. The resultsof this study shown that wind flow just in the January cans reduce human comfort in open spaces and in the design of these spaces have to reduce the amount of the wind flow in this month. In other hand, in the June, July, August months, if the wind flow increase till 6m/s, the human comfort can improve. Wind flow in other month of year has favorable position and it can make human comfort so it is better that the wind speed keeps in the open space and street in this months.
