The scope of this project covered the improvement of energy conversion chains on a community scale, using an exergy basis as the primary indicator. The method of exergy analysis has been found to provide the most accurate and insightful assessment of the thermodynamic features for any process, as well as offering a clear and quantitative indication of both the irreversibilities and the degree of correspondence between the resources used and the end-use energy flows.

It focused on both theoretical and methodological tools, as well as on modelling and on practical implementation aspects. Rather than attempting to to produce another sophisticated modelling, the scope evaluated the practical application of low-exergy approaches on a community scale. In that way project has contributed to technological development, the understanding of system synergies and how to overcome existing implementation barriers.
