According to European Union’s (EU) latest release, countries within Europe are only 2% and 4% regarding the final and primary energy consumption targets respectively, far from the 20% energy efficiency targets posed by the 2012/27/EU Directive. Regarding buildings sector, the stipulations of the recent revision of the Energy Performance of Buildings Directive (2018/844/EU), aim to enhance the efforts for decarbonization of the national building stocks of the State Members by 2050.In Greece, tertiary sector buildings are responsible for the 12% of the final energy consumption, with the majority of them have been constructed before 1980, consuming a large amount of energy and presenting a low performance in terms of energy efficiency, providing, therefore, a great potential for energy saving interventions.This Master Thesis studies the potential energy saving of 4 different types of tertiary sector buildings in order to benchmark energy savings, financial and environmental efficient results. Benchmarking included the study of a 15 buildings complex Resort and Spa Hotel in Lasithi, a bioclimatic architecture Office building in Athens, a Leisure and Sports center in Chania and a Pediatric and Maternity Clinic in Athens. The methodology approach based on the standardization tool developed within the framework of TRUST EPC South initiative, funded by the EU.Several energy saving interventions were investigated for each case, according to energy audits findings, simulation results and owners’ preferences. Results showed a potential consumed energy saving from 62,7% to 8,3% of total consumption for a payback period from 3,1 to 6,6 years. The investment cost per kWh saved for all included cases from 0,01€/kWh to 0,13 €/kWh, highlighting the most efficient measures in terms of energy and financing. The corresponding investment cost per kg of CO2eq saved was varied from 0,007€/kgCO2eq to 0,14€/kgCO2eq for the examined measures of all cases, identifying the measure achieving the higher decarbonization purchasing the less amount of money.
