Maximum engergy efficiency
In addition, with larger glazed surfaces, solar radiation produces more energy to passively heat the building.
Images of buildings taken with a thermal imaging camera, shown here using the example of a pre- and post-renovation with new window façades, visibly demonstrate the potential energy savings.
The definitive variable for the energetic calculation of window and façade constructions is the U-value (Uf for the window frames, Ug for the glazing, Uw for the entire window element). The U-value is the measure of thermal penetration via a construction element and is given in W/m²K.
The lower the U-value, the better, as less heat is conducted via the construction element. With a Uw-value of less than 0.8 W/m2K, WICONA products even meet the requirements for passive housing.
