This dissertation was written as a part of the MSc in Energy Building Design at the International Hellenic University. The residential building stock is constantly growing on a global level. The majority of the European building stock has no or minimal energy related codes. Buildings are responsible for 40% of final energy consumption. Most of the European buildings will remain in use by 2050, so the need for energy refurbishment is necessary. In the first part of this study, a general perspective of the European and Greek building stock is presented. Greek building typology is different than the one in Europe, architecturally and at its building’s characteristics. The programs which fund the retrofitting measures both at Europe and Greece are also presented at this part. In the second part, a case study of retrofitting a typical polykatoikia in climatic zone C in Greece is presented. The state of the art and its findings on retrofitting measures, as well as an economic analysis, are presented. I would like to thank my Professors in International Hellenic University Ms. Ifigeneia Theodoridou and Mr. Agis Papadopoulos, for their constant help and guidance throughout the dissertation period.
