Completed in 2016, this award-winning residence in southwest Germany integrates the SunStyle Solar Roof system into elegant modernist architecture by Yonder, generating 30 kWh/m2 and offsetting 59% of the building’s overall energy use with only 110 m2 of overall roof area. Built into a steep hillside overlooking Stuttgart’s lush river valley, Haus B boasts impressivepanoramic views from every level. When Yonder -Architektur und Design joined Haus B owner, architect Stefan Behnisch, to renovate the 1950s residence, beautiful design came second only to sustainability. SunStyle’s solar roof brought the architects one step closer to their vision of a home that generates more electricity than it uses. Aesthetically, the home’s roof features prominently when approached from above, necessitating an innovative design capable of complementing the home’s exterior. Aside from its sleek, finished wooden interior, the home is characterized by its collection of green features, including PV battery storage for evening energy access and geothermal wells for clean heating and cooling. Since the property’s completion in 2016, Behnisch has gone on to incorporate SunStyle into other designs: among them, that of Stuttgart’s own Steiner School. The architect now calls SunStyle his preferred solution for roofs.
