In the light of the Greek Law 3661/2008 on the “Energy Performance of Buildings”, Greek financial organizations have already established a special lending program with the issuance of “green” consumer loans to individual applicants for buying or installing renewable energy systems for self consumption, energy efficient equipment or other energy saving applications in buildings i.e. improvement of the buildings’ insulation cover. Within the framework of a general improvement of buildings set out by the abovementioned law, a significant part of the Greek banking market decided to support and finance the purchase or construction of real estate of a better energetic category than the minimum standards, as well as the energetic improvement of existing residences, by offering reduced interest rates to loans issued for this purpose.
