Energy efficiency at buildings
Buildings and transportation are the most energy-consuming sectors in Greece. Buildings in Greece account for approximately 36% of the total energy consumption, while, during the years 2000-2005, relevant energy consumption increased by approximately 24%, one of the highest increases in Europe.
One of the main reasons why Greek buildings consume so much energy is that they are old and have no built-in state-of-the art technology, due to the lack of relevant legislation over the last 30 years.
Most of these buildings have problems relating to:
- partial or total lack of heat insulation;
- outdated technology windows/doors (frames/single glazing);
- lack of sun protection on southern and western sides;
- inadequate use of Greece’s high solar potential;
- inadequate maintenance of heating / air conditioning systems, resulting in poor performance.
Another important factor affecting building’s energy performance is tenant behavior. Users-tenants, who lack information about the rational use and management of energy, often tend to waste energy, e.g. by installing individual air conditioning systems without a relevant study, using low efficiency appliances, not performing maintenance of heating systems, etc.
Within this context, the Ministry of the Environment, Energy and Climate Change (YPEKA), having completed the legal framework on buildings’ energy efficiency, has developed a set of financial incentives, with co-financing from the European Union, for the implementation of energy efficiency upgrading interventions in residential buildings, via the “Energy Efficiency at Household Buildings” Program.
