Brief: A group of mixed-use buildings designed on the 2226 principle and so without air conditioning technology is created for Aspern Seestadt, a new and developing Vienna neighbourhood combining sustainability, quality of life and economic dynamism. Realisation: The project offers a location-specific take on the urban design concepts underlying Aspern, its spatially precise transitions revealing the over-arching block structure. The group is open to the surrounding urban space but closed to major traffic routes, while in formal terms the blocks take their cue from the wider urban design.
Features: The space between load-bearing exterior walls and access cores is highly flexible. 2226 buildings offer temperatures of between 22 and 26º C all year round without air conditioning technology. The energy-self-sufficient cooling system in the ROBIN buildings is triggered only when temperatures spike. The 2226 principle relies on the basic tools of architecture – high thermal storage capacity, well-proportioned spaces and window- to-wall ratios – and the 2226 Operating System, which uses ventilation panels to control temperature and air quality. Alongside its energy efficiency, the group’s timeless beauty and durability further enhance its sustainability credentials.
