The Energy performance of buildings directive (EPBD) stimulates the use of passive techniques such as ventilative cooling, aiming to reduce the energy needs for heating or cooling, the energy use for lighting and for ventilation and hence improve thermal and visual comfort. Although inclusion of ventilative cooling in the energy calculation is not obligatory, more and more countries enter ventilative cooling in their Energy Performance (EP) regulation (e.g. Austria, Denmark, Switzerland, Belgium , France and Germany [1]). As the energy calculation is mostly monthly, the effect of ventilative cooling is usually assessed in a rather simplified way.
