Towards Health and Comfort: Architectural Design and Indoor Air Quality in Naturally Ventilated Classrooms
The maintenance of adequate indoor environmental quality is crucial for the health and performance of building occupants. In educational buildings, particular attention should be given to air quality due to high occupancy levels and the significant impact that a conducive learning environment can have on a student’s lifelong achievements. Existing literature suggests that design strategies can influence air quality by promoting ventilation and air circulation. However, in Brazil, this field of study remains relatively unexplored. Therefore, the aim of this paper is to examine the relationship between architectural features of higher education classrooms and their indoor air quality. To accomplish this, a comprehensive database comprising architectural characteristics of 527 classrooms from a public university that utilizes natural ventilation as the primary air conditioning mode was compiled. The focus was placed on factors that could potentially affect indoor air quality, such as the window-to-wall ratio, the presence of cross ventilation, and occupancy density. The number of air changes per hour was calculated for a representative classroom with and without cross-ventilation, and the results were compared to recommended air renovation rates found in the literature. The findings revealed that only 12% of the database consisted of classrooms with cross-ventilation design in naturally ventilated settings. Moreover, the calculated air renovation rates for cross-ventilated classrooms were 3.8 times higher than those for single-sided ventilated classrooms. Given the limited research on this topic in Brazil, this study aims to contribute to the ongoing discussion and raise awareness about the significance of air quality in academic environments and its correlation with architectural design.
