This publication acquaints the prospective marketplace with the potential and underlying logic of the Integrated Utility System (IUS) concept. This system holds promise for educational and medical institutions seeking to reduce their energy costs. The generic IUS concept is described and how it can be incorporated into existing heating and generating equipment to obtain increased system efficiency through heat recovery and recycling is discussed. Two studies are described to illustrate the positive impact of IUS, especially over the long term. The multiplicity of subsystems available to suit the individual needs of institutions is also covered in this total energy systems document. (MR)
