A house that produces so much energy that you can also charge your car with it. That was the goal of Marjo Dashorst and Han Roebers in the realization of their new home in Zutphen, the Netherlands. An 8 kW heat pump with a closed source at a depth of 180 meters, a heat exchanger in the ventilation system, and 32 solar panels with an installed capacity of 9.6 kW are the most important installations that prove this to be true.
Sustainability has also been a leading factor in architectural design. Both for the spatial organization and for the detailing. The house is very well insulated all around (RC 7 m²K/W) and provided with vegetation roofs. Advanced remote-controlled outdoor awnings have also been installed, and skylights provide daylight in the darkest spots. And in the double-height living room, high windows facing East and West provide daylight all day, despite the Northern orientation.
An overhang on the South façade provides the kitchen with shade in summer. The expressive wooden facades are made from 60 years old re-used Azobé campshedding. The varying widths of the elements and the beautiful patina gives the houses an equally touchable and tough character.
The wooden facade, the sand-lime brick structure, and the terraces of re-used Stelcon plates make the house not only sustainable, but also largely circular.
