Introduction The European Directive on the energy performance of buildings (EPBD) encourages the European Union member states to approve energy policies that promote the implementation of very low and even close to zero energy buildings. Keywords: Naturally-ventilated PV Double-skin façade BIPVġ. It was found that the cooling needs are marginally higher for all locations considered, whereas the impact of the façade on the heating needs is weak as these needs are already low for these all locations. Coupling of the system to a simulated building was achieved with the aid of TRNSYS, and this combined system was evaluated in terms of heating and cooling needs for a range of French climates.

Validation of the model was undertaken using experimental data from a full scale prototype system installed in Toulouse, France as part of the RESSOURCES project (ANR-PREBAT2007). For a given set of meteorological conditions, the surface and air temperatures, mass flow rate and PV power output are obtained by solving a system of thermal and aerodynamic balance equations.
The model describes the active envelop in terms of a simplified geometry, and includes parameters such as density of PV cells, relative coverage of degree of transparency/opaque surfaces, and the ratio of height/width of the double-skin. A simplified physical model of the system is proposed for the summer operating configuration, which is more challenging from a numerical perspective. Such an arrangement exploits the heat transfer between cavity air, the PV façade and the primary wall of the building for the purpose of PV cooling in summer (with natural convection) and heat recovery in winter (mechanical ventilation). This paper addresses the simulation of a partially transparency, ventilated PV facade integrated into the envelope of an energy efficient building.
