Aim of this paper is the analysis of the energy performance of secondary school buildings in North Greece and the investigation of proposals for their energy upgrade. The survey was carried out by monitoring the energy performance of 20 secondary school buildings in the prefecture of Evros in Thrace and by simulating representative school buildings. Energy data both for heating and electricity; together with other information concerning structural details and operational characteristics for a period of 5 years (2001-2005) were collected. The energy data for the secondary schools are presented and compared with data from other regions in Greece. The mean heating energy consumption of secondary school buildings in the prefecture is 70.6 kWh/m2; with insulated buildings performing with 27% less energy consumption than non-insulated buildings. Simulation of representative school buildings in this area suggests that measures for natural lighting; reduction of infiltration losses; controlled ventilation during the winter; shading and natural ventilation during summer and the effective functioning of heating and lighting system are the major priority for the school building stock. Especially in the ‘old school buildings’; this type of interventions are necessary not only for achieving energy efficiency but for obtaining thermal comfort conditions in their interior.
