Problem statement: Today, the issue of thermal comfort has been raised as one of the important factors in the quality of urban open spaces along with physical factors. Basically, citizens tend to be in spaces where they feel thermally comfortable. Due to the effect of various parameters in urban open spaces that affect the thermal comfort of users and the lack of codified principles in this regard, the creation of such a space in an urban area has become difficult to identify and meet the thermal needs of city designers.
Results: Studies showed that in the open spaces of the urban environment, due to the influence of various factors, absolute thermal comfort conditions can not be achieved throughout the day; Rather, thermal comfort conditions are expected to be provided for certain hours. To improve thermal comfort in urban open spaces, elements such as vegetation, water, proper orientation, type of materials, color, activity rate and coverage rate are important. It is obvious that by using these factors and observing the time of presence in the open space of Rudkenar sidewalk, thermal comfort will be provided in it.
Method: The research is applied-developmental in terms of purpose; And is based on analytical method. In this method, in order to study the microclimate, the software simulation technique (Envi met) has been used as one of the most complete simulation software in the field of urban microclimate, and the values ​​of PMV thermal comfort index (average vote prediction) using simulation in different parts of the route The designed sidewalk that has different conditions and situations has been calculated and the changes of two factors of temperature and radiation and its effect on the thermal comfort of Khorramabad river in Lorestan in summer have been studied.
Conclusion: Finally, it was found that factors such as choice of direction, walking time, sidewalk width, the presence of trees and vegetation, shade and water, as well as some user characteristics such as metabolic rate and activity, coverage rate in terms of thermal comfort in this season of the year Has been impressive.
