A SOLUTION TO PROBLEMS OF GROWING COLLEGE ENROLLMENTS IS TO INCREASE THE EFFICIENCY OF USE OF EXISTING SPACE TO MAKE ROOM FOR MORE STUDENTS, RATHER THAN TO RESTRICT ENROLLMENTS OR TO CREATE MORE SPACE. PLANNING OF COLLEGE FACILITIES MUST INCLUDE ANALYSIS OF THE PRESENT PLANT, THE INSTRUCTIONAL PROGRAM, THE STUDENT BODY, AND THE FINANCIAL STRUCTURE. ON A WELL PLANNED CAMPUS, FACILITIES ARE ZONED ACCORDING TO FUNCTION. FACILITY UTILIZATION IS A FUNCTION OF THE EXTENT OF SPACE PROVIDED, ROOM-PERIOD UTILIZATION, AND STUDENT STATION UTILIZATION. IMPROVEMENT OF UTILIZATION IS A FUNCTION OF CLASS DISTRIBUTION, LENGTH OF THE WEEK, THE SCHOOL YEAR, CURRICULUM UNITS AND CREDITS, RELATIONSHIP OF CREDITS AND CLASS HOURS, LABORATORY SPACE, FLEXIBILITY OF CLASSROOMS, PROLIFERATION OF COURSES, PROPRIETARY ATTITUDES OF STAFF, AND PRESSURES FOR MORE SPACE. A SPACE UTILIZATION WORKBOOK IS INCLUDED. THIS DOCUMENT IS ALSO AVAILABLE FROM EDUCATIONAL FACILITIES LABORATORIES, 477 MADISON AVENUE, NEW YORK, NEW YORK. (WO)
