Abstract: Among the passive strategies that can improve the thermal comfort in built environments, natural ventilation (NV) is important not only for improving thermal comfort but also for maintaining air quality. In this context, a comfortable thermal environment has a significant impact on learning activities. In studies evaluating thermal comfort and NV quality in indoor environments through computer simulations, it becomes necessary to assume a fixed schedule for window opening. This research aimed to investigate the window operation schedules used in computer simulations of school environments with NV, located in the southern region of Brazil, as well as the influence of the window opening setpoint on the assessment of thermal comfort. For this purpose, a systematic literature review was conducted, which resulted in 23 studies. The results showed that 52.17% of the selected studies considered a setpoint temperature to allow window openings, facilitating NV, with 25 ºC being the most commonly used temperature. In less than 20% of the selected studies, window openings were defined when the operating temperature exceeded the comfort temperature set by the ASHRAE Standard 55 adaptive model. Only 2 of the collected articles collected compared different VN setpoint temperatures in the same model. In these studies, it was indicated that the variation in setpoint led to differences in thermal comfort of less than 2% over an annual period.
