AN INTEGRATED EVALUATION METHOD FOR ENERGY SUPPLY SYSTEM

The introduction of sustainable energy systems is strongly associated to what choices real estate owners make among different energy supply system options. This paper reviews briefly the evaluation criteria and methods of energy Supply system, from technical, economical, environmental and social aspects. A new methodology for the integrated evaluation of the energy supply system's feasibility is presented, which adopts the grey relational analysis method. As an example, three energy supply systems to provide cooling, heating and power to users are synthetically evaluated and compared in multi-criteria. The weights, used in multi-criteria evaluation, is discussed and suggested. The results prove that the grey relational analysis is an effective tool for decision making compared to single criteria evaluation.
