Introduction: One of the most important issues in the design of educational buildings, especially schools, is providing thermal comfort for students in classrooms. If the design is correct, in addition to providing the thermal comfort needed by the students, we will reduce the energy consumption in these buildings. The purpose of the research: analysis of the thermal behavior in the school buildings of Rasht city, in order to identify the damages and problems in the buildings built by the General Department of Renovation, Development and Equipping of Schools in Gilan Province. Research Methodology: In this research, an attempt has been made to simulate one of the schools in the temperate and humid climate of Rasht city in the accurate design builder software, and with the powerful engine of Energy Plus, the thermal behavior in this school has been tried in order to investigate and generalize it to other schools in the climate. Let's analyze the moderate and humid city of Rasht Geographical scope of the research: This research was conducted in the temperate and humid climate of Gilan province, Rasht city. Results: After the simulation, it was determined that the location of the air intake and exhaust windows was suitable according to the CFD analysis and the building had good natural ventilation throughout the year. Also, the results show that the wall 23%, lighting 21%, glass 20% and equipment 17% respectively include the most energy loss in this building. Analyzing the heat loss in the coldest month of the year in the studied school, graph 5- but it is facing a big difference with the energy loss in the warm month of the year. In the coldest month of the year, the external wall 48%, glass 26% and the roof 20% of energy loss account for the most energy loss in this building.
