In this paper, we describe and evaluate a ventilated BIPV(T) system that could be used in combination with a ventilation heat pump to realise energy efficient dwellings. European regulations are aiming at (near) zeroenergy buildings in the near future. Since a large share of the energy demand in the built environment in continental Europe consists of heat, the combination of both solar heat and solar electricity production in one roof is an interesting option to increase the share of renewable energy. We modeled the ventilated BIPV system and validated the model with a field test. In the field test we also tested the impact of several measures to improve the generation of useful heat, like fins and flow patterns. The BIPVT/ventilation heat pump concept consists of: a prefab building integrated PV element that includes insulation and a modified ventilation heat pump. Traditionally, a ventilation heat pump uses the source heat from the ventilation air of a dwelling. The heated air under the PV panels could potentially supply a larger share of the source heat that would be required to supply the full heat demand for space heating and domestic hot water.
