The present study aims at determining the conditions of climate comfort using Rayman software. In this research,the current status of high-rise building in Janbaz Street of Mashhad and analysis of daily climate data in 2015 including temperature,saturated steam pressure,relative humidity and wind speed is investigated where such data are obtained from the Meteorological Organization of Khorasan Razavi Province. The research method is descriptive — analytical and filed observations as well as site visit were used to collect the data. In view of the population size with 102 subjects selected by random sampling method,the climate characteristics are analysed and climate comfort is estimated and analysed by Rayman software.
