The European Energy Performance of Buildings Directive (EPBD) requires a certain Energy Performance Assessment (EPA) to be conducted for each building, to obtain an Energy Performance Certificate. For this purpose several software tools have been developed enabling theaudit and assess of either residential, or tertiary buildings and the calculation of the energy need sand energy consumption in line with EPBD. In practice, however, significant differences between the calculated results and measurements are usually recorded, especially for the electrical consumption, since most of the EPA tools calculate only part of the electric energy consumption in a building. Scope of the paper is to present field measurements for the electrical consumption for different buildings in a University Campus in Greece. The recorded data are analyzed and compared for a specific building with the corresponding obtained by an EPA software. Differences between the two approaches are discussed, while interesting remarks are made concerning the electrical load profiles of University buildings and the rational use of lighting and air-conditioning systems during non-working hours. From the analysis of the results proper electric consumption control strategies of the electrical loads can be proposed, utilizing intelligent control systems.
