Utilization of classrooms is defined by the student station size, room use in terms of hours, and station/seat
occupancy rate. Spaces can vary by institution or campus, depending upon the existing or desired mix of classroom
capacities, size of the institution, hours of use and types of programs. The station/seat space factor includes an
allowance for students, instructor, internal circulation and 5% service. It can vary by room subtypes and type of
seating, and depends upon the desired mix of room capacities. Architects should take into consideration the
geometry of the room, since form can also impact the capacity of the room rendering a less efficient space
