The IAQ4EDU project validated natural ventilation models for educational buildings

The IAQ4EDU project validated natural ventilation models for educational buildings. This work provide the basis for the developed window operational guide for school teachers. The article has been now published in the top-indexed journal Building and Environment (JCR-Q1, Impact Factor: 7.1), is entitled "Validating single-sided natural ventilation models for educational buildings". The PhD student Sen Miao conducted the research under the supervision of Prof. Marta Gangolells, principal investigator of the IAQ4EDU project, and Prof. Blanca Tejedor.

To maintain good indoor air quality in schools, it is often necessary to apply single-sided natural ventilation models using urban weather stations, since the local weather station is not available for most schools. However, the field study that validated the ventilation models with full-scale experiments in classrooms is very limited. Therefore, this study validated 6 existing single-sided ventilation models based on two field measurement campaigns conducted in naturally ventilated educational buildings, including the Warren & Parkins (1977 & 1985), De Gids & Phaff (1982), Larsen & Heiselberg (2008), Caciolo (2013), Tang (2016), and EN16798-7 (2017) models. The study also analyzed the cause of model prediction errors with respect to building characteristics such as weather station distance, building location, room floor, and incident wind direction. The results of this study provide the basis for the developed window operational guide for school teachers.
