Abstract: In this work, the potential of the increase in exergy and energy efficiency of the Greek construction and Food, Drink and Tobacco (FDT) industries has been examined using energy and exergy analysis methodology. These two industries play a vital role towards sustainable development of the country. The continuous increase in energy use in these two industries during the years 1971–2000 shows that both remain steadily in an ascendant orbit. The aim was to analyse and compare the energy use and exergy consumption in the Greek construction and FDT industries to gain insights into each sector|s efficiency of energy use.

Keywords: energy efficiency; exergy efficiency; exergy analysis; construction industry; FDT industry; Greece; food drink and tobacco; sustainable development; sustainability.
