Environmental thermal conditions around us have a significant effect on the efficiency of people who use these open spaces especially on university campuses where many students from different cities spend their most of time. This paper focuses on the comparative study of the effects of the sky view factor (SVF) on mean radiant temperature (Tmrt) and the thermal indices derived from these parameters in two different universities in Tehran: IUST and University of Amir-Kabir , Thermal comfort of these campuses have the different condition due to their different level of shaded open spaces. Physiological equivalent temperature (PET) is calculated via Rayman for thermal comfort assessment in spring and summer 2015. Subsequently, it determined that by decreasing SVF to 0.4, Tmrt will decrease to 3.04°C. These changes of Tmrt effect on PETs reduction. PET comparison in two campuses illustrates that in an average of PET, there is 0.86°C difference between two campuses in the hottest month of the year (July). IUST campus is 1.39°C cooler on the PET scale. In conclusion, increasing shaded spaces by increasing green spaces and trees can create cooler campuses. Integrated design of shaded open spaces with their architectural forms is recommended as a design strategy to the designers to create a responsive environment in terms of thermal comfort. By this means cooler campuses are more prone to be used by students and their activities.
