Exergy indicators in the building environment
The objective of this work is the application of the exergy analysis to the building sector and the introduction of suitable exergy indicators. The indicators are tools which are representative of the system under study and provide reliability over time, information to policy makers and awareness of potential environmental problems arising from human activities. The application of the exergy analysis of a new office building's life cycle in Greece constitutes a big part of this work. A hypothetical case involving the application of renewable energy sources in a range of 10–50% of the overall exergy needs is examined.
