Thank you for the comment. If you happen to know the number of the study rooms you were in which felt too hot, please let us know those details. We can work better with campus Facilities if we know the specific location. You probably wish to shut the door, but it is always an option to keep a study room door open and this may help with the airflow. If the room has shades, draw them down. Also, we have fans at the service desk for checkout if you want to try that in the meantime. We will check the rooms and areas and speak with Facilities. Thank you for reporting your experience and this issue.
