The IAQ4EDU project has developed a new method to estimate CO₂ generation rates in schools with natural ventilation

The IAQ4EDU project has developed a method to estimate CO₂ generation rates among students in schools with natural ventilation. The results have been published in the journal "Building and Environment" (JCR-Q1, Impact Factor: 7.4) in April 2024, titled "Estimation of children’s CO₂ generation rates in naturally ventilated educational buildings." This study was conducted by Ph.D. candidate Juan Tugores, under the supervision of Dr. Marcel Macarulla and Dr. Marta Gangolells, the principal investigator of the IAQ4EDU project.

Currently, regulations establish fixed values for CO₂ generation rates based on factors such as sex, age, body mass, and activity level. Estimating these rates accurately in real environments is a significant challenge. This article develops a model for estimating CO₂ generation rates in real environments, using grey models, using in-situ measured data (such as CO₂ concentration, classroom occupancy, and door and window openings), and accounting for variability in student activity patterns and inherent changes in natural ventilation.

The RC network of the deterministic function of the model
