Abstract
The air quality in educational spaces has a significant impact on the health and performance of students and instructors. Indoor and outdoor air pollution can lead to respiratory problems, reduced concentration, and an increase in illnesses. Due to the complexity and diversity of pollutant sources in these spaces, achieving complete air quality improvement through a single therapeutic technology is challenging. This study explores innovative strategies for pollutant absorption in the design of educational spaces, specifically aimed at reducing indoor and outdoor air pollutants.The research method involves data collection from scientific and research sources and a review of the existing literature on the use of absorbents and pollutant absorption systems. This study evaluates two main approaches: the use of external absorbents in building facades to control pollutants from external sources and the use of internal absorbents to reduce indoor pollutants.The results show that air filtration systems and absorbent coatings in building facades can effectively reduce external pollutants such as PM2.5, PM10, and VOCs. Additionally, the use of nanomaterial-based absorbents in indoor spaces is particularly effective in reducing indoor pollutants such as CO2 and formaldehyde. These materials, due to their photocatalytic properties, significantly enhance pollutant absorption when exposed to sunlight.Furthermore, the study concludes that attention to proper orientation and natural light penetration in the design of educational spaces can increase the efficiency of these materials and pollutant absorption systems. The use of these materials could pave the way for sustainable architecture and the use of passive ventilation systems that are free of pollutants in the future.
