Due to the lack of national building regulation regardingthe energy requirements of Directive 2002/91/EC (EPBD) in Greece, Southern countries (Italy, Spain and Portugal) have been selected as index reference because of the similar climatic conditions and location in order to report the stage of Directives implementation (energyperformance calculations and energy rating procedures)for a future enforcement in Greece.Regarding the increasing energy demand in the island of Crete, this paper aims at the estimation of energy saving in buildings for the island of Crete. More precisely, a simulation of an office in the city of Heraklion was implementedusing TRNSYS program. Various energy saving measures were tested and compared to a reference case.
