Assessment of innovative ventilation in the framework of the EPBD—A probabilistic approach: RESHYVENT project

The market uptake of innovative, energy efficient concepts in the building sector is to a large extent influenced by the stimuli found in building regulations. The Energy Performance of Buildings Directive (EPBD) makes the application of an EPB regulation mandatory for new buildings and for major renovations. If one is obliged to make an assessment of buildings in terms of energy performance, it is clear that one should be able to assess all kinds of building designs and of technologies. However, the EPB regulations (present or under development) clearly not cover all possible technologies. Among the technologies that are typically not covered by the standard procedures are innovative ventilation concepts, e.g. hybrid ventilation in dwellings. This paper wants to highlight the need for the development of a coherent approach, based on a mixture of European measures and national actions.
