Indoor air quality is paramount for the health and well-being of individuals, especially in enclosed spaces like office buildings, schools, hospitals, homes where people spend a significant amount time. Ensuring good indoor not only essential reducing symptoms such as headaches, eye respiratory irritation, fatigue, difficulty concentration, but it also key component sustainable building practices aimed at promoting long-term environmental balance. This study aims to explore impact microclimate fungal microbiota on cognitive performance occupants university classroom, which part cultural heritage building. The research delves into various microclimatic parameters, including temperature, relative humidity, CO2, volatile organic compounds, O2, particulate matters (PM2.5 PM10), understand their influence development manifestation associated with Sick Building Syndrome. Over course year-long investigation, microbiological samples were collected, revealing presence 19 species, Cladosporium, Alternaria, Aureobasidium being most prevalent genera. These species found thrive an environment characterized by inadequate ventilation, posing potential risks occupants, allergic reactions infections. Microclimatic parameter values mean temperature 22.9 °C humidity 38.5% indicated moderate conditions proliferation, occasional high levels PM2.5 CO2 periods poor quality, negatively influencing comfort occupants. questionnaires completed 190 students showed that 51.5% reported 44.2% frequent sneezing, 43.7% severe linking these increased PM2.5. novelty lies integrated approach assessment educational building, highlighting need improved ventilation management enhance performance, while emphasizing balances occupant preservation heritage.
