This research aims to analyze the impact of humidity on educational institutions, focusing on the selection of appropriate building materials based on the institution's geographical location. It also seeks to improve the design of educational buildings to mitigate the effects of humidity, particularly in coastal areas. The study employs a descriptive-analytical approach, analyzing the impact of humidity on educational buildings over different time periods and collecting data from institutions regarding building deterioration. The results show that humidity negatively affects the lifespan of buildings, especially during winter and in coastal regions, and exacerbates health problems such as respiratory illnesses. The research recommends improving building design, using moisture-resistant materials, and enhancing ventilation systems. It also suggests implementing regular maintenance, encouraging research into moisture-resistant technologies, and developing building standards specific to educational institutions.
