Designed by C. F. Møller Architects in cooperation with Moe & Brødsgaard, Cenergia, Phillips, Schüco, Erik Juul and Vogt landscape, the Housing+ is a passive housing that supports on-site renewable energy generation. Located around Aalborg waterfront in Denmark, the pilot-project features a long sloping elevation, which provides a plane for a 1200 m2 solar array to produce the 104.400 kwh of electricity (annually) to power 60 housing units without external resources. The sustainable housing uses the fjord to power heat pumps, while a highly insulated water-tank (W 3 x H 12 m) is integrated to store the solar energy. Apart from solar array and heat pump, the housing project also integrates 4 vertical low-noise wind turbines that generate energy to recharge electric cars. Moreover, the slope shelters a public gazebo and cafe for community gatherings.
