When a new school facility opens, most of the staff and students are eager to get inside quickly and check out the new surroundings and all the cool stuff that will make their days of teaching and learning more comfortable and enjoyable. In their excitement, they are unlikely to pay much attention to what every one of them has to pass through to get to their destination: the doors into the school. In a well-designed school, administrators and designers have given a lot of thought to doors--the ones that let people in and out of the building, as well as the ones that separate spaces inside the facility. In deciding what kind of doors will be installed, schools and universities have to consider who will be coming in and out of them; how much control they want over those comings and goings; what level of monitoring is necessary and desirable for each entryway; what amount of technology can be included to assist that monitoring; how much wear and tear the doors are expected to endure from a constant flow of students and staff; how much protection they are expected to provide from fires, hurricanes, tornados or external contaminants; and when and how they can be locked or unlocked. They also should look nice. This article offers tips compiled by the National Clearinghouse for Educational Facilities (NCEF) that can help facilities managers choose the right kind of doors.
