Energy efficient ventilation for NZEB in Mediterranean countries

In the definition of the nZEB, the use of only one requirement is misleading. Different requirements are combined to a coherent assessment of an nZEB and to fit the definition given by the EPBD (2010/31 /EU) in article 2. In this presentation, we focus on the first requirement reflecting the performance of the building envelope characterised by the energy needs for heating and cooling.
