Building energy systems and the use of energy in an institution, (The University of Canterbury's Ilam campus) are .investigated in this report. The existing installed systems are analysed and alternative "State of the Art" building energy systems are investigated. While technical and economic factors are the main criteria by which these systems are judged, commercial acceptability in New Zealand has also been a major concern. Section 1 details existing campus building energy systems. Section 2 examines the following alternative systems: 1. Peak Shaving of electrical demand peaks, is compared with energy cost savings from electrical load reductions. 2. Provision of both heat and electricity needs for the campus by combined Heat and Power (CHP) plant. A CHP plant analysis spreadsheet was developed to help determine the performance of the plant under the varying simultaneous heat and electrical loads on the campus. 3. Alternative air conditioning systems are examined including, centralised district cooling schemes, evaporative cooling, and cold thermal storage. 4. Conversion of the existing steam heating system to hot water operation.
