SWISSPACER Ultimate warm edge spacer bars are fitted throughout the triple glazing in a house in Alsace, France, declared by architectural and planning firm KMO to be ‘Europassive’.
KMO owner Vincent Kempf said that he wanted to develop and focus on existing certified Passivhaus standards: “We wanted to combine the most demanding energy efficient criteria with the latest innovations. This applied to all construction aspects of the building, living comfort, as well as ensuring protection of the surrounding environment with a strong visual appearance.”
The north and east sides of the property have only a few window openings, but the south side is almost completely glazed, allowing for sunlight to come into the interior during the winter for warmth.
The glass façade consists of triple-glazed insulating glass with a U-value of 0.5 W/m2K and a light transmittance of 61%. In summer, external solar protection prevents overheating of the interior. Manual ventilation is possible only through the doors – all windows in the property as well as the façade have fixed glazing.
