Abstract

In the present paper, the potential of the Greek building sector is examined using the energy and exergy analysis methodology. The building sector can play a crucial role in the efforts towards sustainable development. The building sector plays a significant role in the Greek economy as it engages more than 310,000 employees and 32,500 engineers (2003). The building sector has been one of the most rapidly developing sectors of the Greek economy in the last few years. The construction sector contributes significantly to the gross national product in 2005 (10%), notably higher when compared to 1997 (6.4%). Continuously increased energy consumption in the construction sector over the past 40 years (1961&-2001) shows that this industry remains steadily in the ascendant. The aim of the present study is to analyse the energy and exergy utilisation in the Greek building sector in order to gain awareness of the sector's efficiency.
