Greece

Low or Zero Energy buildings are becoming increasingly popular and the use of passive-house principles are providing a solid foundation for achieving energy consumption targets and good indoor quality. However, this design methodology has been well received in central and northern Europe than in south and the Mediterranean, where people are used to houses that are open to the external environment. This habit is in contrast to the basic principles of the good airtightness, the energy efficiency and the achievement of a good Indoor Air Quality.

According to researchers, climate change is inevitable in the 21st century. As far as Greece is concerned, this climate change will be related to an increase in ambient surface temperature and to a decrease in annual precipitation. On the other hand wind patterns will not change significantly. Also, no significant changes are expected for global solar radiation. Regional climate models related to Greece show low uncertainties. The climate of Greece is typical Mediterranean with wet, cool winters and hot, dry summers.
