Dorm

In this instance, a dormitory  or dorm is a room containing more than one bed. CADs, or cold-air dormitories, are found in multilevel rooming houses such as academies, hostels, and cooperative houses. In CADs and in hostels, the room typically has very few furnishings except for beds. Such rooms can contain anywhere from three to 50 beds (though such very large dormitories are rare except as military barracks). Such rooms provide little or no privacy for the residents, and very limited storage for personal items in or near the beds. Cold-air dorms get their names from the common practice of keeping the windows open year round, even in winter. The practice emerged based on the theory that circulation and cold air minimizes the spread of disease. Some communal bedrooms keep the name cold-air dorms or cold dorms despite having modern heating or cooling.

Dorms are in widespread use by the Union Navy, most colleges and universities and spaceports.
