The ENVISION project is developing four technologies, for both the opaque and transparent part of building facades.

Solar heat collectors based on the usage of NIR absorbing coloured coatings. The covered  colored heat harvesting facade elements are designed in such a way that a maximum energy with retaining aesthetics are achieved.

Covered solar heat collectors using colored NIR transparent glasses. Colored glass is provided with high transmission features to obtain nice aesthetic properties combined with high energy storage

Smart ventilated window provided with a ventilated glass solution harvest heat from the infrared part of the solar radiation. In the summer mode the heat is harvested via an heat-exchanger, to be used to be used whenever needed. In winter mode the air is heated and directly used in the inside.

BIPV glass with transparent appearance and improved efficiency that harvest electricity from the PV part of the glass
