In this study, standard EnergyPlus Weather (EPW) climate data were utilized over a 14-year period (2009 to 2023). The research methodology was based on the parametric analysis of hourly climate data in accordance with ASHRAE Standard 55 and the utilization of the Predicted Mean Vote (PMV) model for thermal comfort assessment. Meteorological parameters (air temperature, soil temperature, dew point temperature, humidity, wind speed and direction, and solar radiation) were analyzed using Climate Consultant software, and the results were presented in the form of bar, line, and scatter plots. The results indicated that the climate of Sanandaj, with its hot summers and cold winters, necessitates specific strategies in architectural design. The cold months of the year (January, February, November, and December) require heating systems, while the hot months (July and August) require cooling systems. Additionally, the months of March, April, and October, with the highest wind speeds, have the potential for natural ventilation. Based on the research findings, strategies such as the use of high thermal mass materials, passive solar systems, proper insulation, night ventilation, and adjustable shading devices are proposed. These strategies can help optimize energy consumption and provide thermal comfort for residents in the mountainous climate of Sanandaj.
