Based on data obtained in earlier phases of a comprehensive planning study, this report presents--(1) the development of a space projection model responsive to unique institutional requirements, and (2) a forecast of the aggregate academic space needs of higher education in Indiana for a given future enrollment level. The scope of the study and a general outline of the projection model are presented, followed by detailed descriptions of the development of the model and space requirement factors for each functional space category. Specific assumptions and limitations for each category are noted, together with a sample calculation for a hypothetical institution. The calculations for all space categories are summarized at the end of the model development section. The total projected requirements and the kinds and amounts of additional space needed are discussed, briefly analyzed, and summarized by school grouping and space type. (FS)
