    The Effect of Occupancy and Environmental Physical Variables on Classrooms’ Natural Ventilation: A Path Modeling Approach by Rogério Duarte, António Moret Rodrigues, Fernando Pimentel, Maria da Glória Gomes

    Published 2024-12-01
    “…In spite of the statistical significance of the path model as a whole and its detailed causal relationships (direct, indirect, and feedback), only 58% of classroom ventilation variance is explained by the selected input variables. Because naturally ventilated classrooms depend significantly on occupants’ interactions with the built environment, i.e., opening/closing windows and blinds, extending path modeling to include additional personal and context-related drivers of occupants’ behavior would allow for further insights into the complex multi-domain topic of natural classroom ventilation.…”
