Solar-powered Dutch home produces all of its own energy with surplus to spare

When Marjo Dashorst and Han Roebers set their sights on designing a sustainable home in Zutphen, a municipality on the east side of the Netherlands, the couple turned to Amsterdam-based practice Attika Architekten to realize their dream. The goal was to develop an energy-efficient home that would not only meet all of its own energy needs through renewable systems but also be capable of producing enough surplus energy to charge an electric car . The resulting project, aptly titled the Energy Plant House, combines solar panels, passive solar strategies and a highly insulating envelope to achieve its energy-plus goals. In contrast to its more traditional, gable-roofed neighbors, the Energy Plant House sports a contemporary, boxy appearance. The three-bedroom home is spread out across two floors: a ground-floor volume clad in sand-lime brick and a partially cantilevered upper volume wrapped in reclaimed 60-year-old Azobé campshedding planks. Reused Stelcon plates anchor the terraces. Large sliding glass doors on the north and south sides of the home create a seamless connection between indoors and out.

Energy production is supplemented with a 8kW heat pump with a closed source at a depth of 180 meters as well as a heat exchanger in the ventilation system. Energy efficiency is optimized with a well-insulated envelope and vegetated roofs. Strategically located windows — from the skylights to the tall east and west windows — flood the interior with natural light despite the northern orientation. Unwanted solar gain from the south end is mitigated with an overhang from the cantilevered upper volume; advanced remote-controlled outdoor awnings have also been installed to shade the residents from harsh sunlight. + Attika Architekten Photography by Kees Hummel Fotografie via Attika Architekten
