Award: R-House
Developed by the design team as a simple folded surface, the form of the R-House can be seen as a (literal) twist on the traditional gabled roof: The architects set the gable askew and tucked small front and back porches beneath it. Energy-efficient features are integrated into the house's design. Ample windows with triple-pane, double-low-E glazing on the south face optimize solar gain, while external shading and an operable skylight aid passive cooling. Heating demand is met entirely by warming the required fresh air supply. The house's compact form enhances its energy performance, which meets Germany's stringent Passivhaus standard.
