The buildings and the transport sector are the biggest consumers of energy in the country. Buildings in Greece account for approximately 36% of the total energy consumption and, in 2000-2005, they increased their energy consumption by about 24%, one of the highest increases in Europe.

One of the main reasons why the Greek buildings are particularly intensive is their antiquity and the failure to incorporate modern technology to them, due to lack of relevant legislation in the last 30 years.

Most of these buildings are facing issues such as:

• partial or total lack of insulation,
• obsolete frames (frames / odd windows)
• lack of sun protection of the southern and western facades
• insufficient use of the high solar potential of the country,
• inadequate maintenance of heating / air-conditioning resulting in poor performance.

An important parameter also determines the energy efficiency of a building is the behaviour of the occupants. The lack of information of users-residents regarding the rational use and management of energy, often leads to wasteful behaviours such as installing individual air-conditioning systems without trial, the use of low performance devices, or non-maintenance of the heating system, etc.

In this direction, the Ministry of Environment Energy and Climate Change (Y.P.E.K.A.) by completing the institutional framework for the energy efficiency of buildings progresses, co-funded by the European Union, in a package of economic incentives in order to made energy upgrading interventions in buildings in the domestic sector, through the "Saving at home" program.
