CREPR — Reduce operating costs & realize the full value of your real estate assets. A Comprehensive Real Estate Performance Review (CREPR) is a systematic review of real estate at a given location to identify the assets, liabilities and risks of each location in terms of energy use, occupant health and welfare and environmental impact. The areas evaluated include the site (including natural and man-made systems and features,) occupied and utility buildings and structures and the operational procedures used for operation and maintenance of the location.
