# Ventilation Strategies to Ensure Thermal Comfort for Users in School Buildings: A Critical Review
## 3 Results  
Several studies focus on different ventilation strategies to ensure thermal comfort in school buildings. Table 3 summarizes these studies, adding insight on the type of ventilation studied and the key aspects of the main selected articles (year of execution, location and climate, type of building, and season of the year when tests and measurements are carried out). \begin{table}
