1 Space Planning & Management Description Employ current understanding of potential of building stock (through undertaking building condition assessment and developing new standards for space management and scheduling) and use this as the basis for revising the campus master plan. Objective is to increase space and building use efficiency to limit the need for new construction. If growth rates experienced between 1980 and 2010 continue, CWRU is projected to add approximately 3.6 million new gross square footage by If this growth was limited, the capital costs, operating expenses and associated energy expenses would be avoided Assumptions Time Frame Years 1-10 Next Steps Draft specific Space Planning & Management policy that outlines discrete steps and processes that need to be put into place to enable this abatement opportunity.
