On an inspection visit of our hostel for deaf students, a team from the Ministry of Social Affairs didn’t like that there was no ceiling above the dorm rooms but rather open space up to the metal roof twenty feet above. From my understanding, that design allows the hot air to rise well above the living area and also keeps the hot roof above the humans. They wanted a suspended ceiling, though, so now they are getting one. It will be interesting to learn from the students, when they return, if the rooms are now hotter or cooler.
