Junghans presents on energy optimization for award-winning 2226
Lars Junghans, Assistant Professor of Architecture, presented his energy optimization plan for the award-winning office building 2226 during the February 12-13, 2015 Vienna Congress on Sustainable Building. The presentation, titled “Sustainability and resiliency of the 2226 Building in Lustenau. What can we learn for the future?” discussed the considerable investment and operating costs of HVAC services and how simpler solutions, like those implemented in 2226, can show a way how qualities passive houses are famous for could be achieved with less bulky building services.
Office building 2226 in Lustenau, Austria was designed by Baumschlager Eberle in 2013 and has been praised for its modern energy optimization systems having no cooling, no heating. 2226 has also been shortlisted for the 2015 Mies van der Rohe Prize and won a 2015 German Design Award in the category of Excellent Communications Design – Architecture and Urban Space. The German Design Award jury added, "In this instance it is not the design that is the focus of attention, but the attitude. For this building blazes new trails, having no heating or cooling system. Yet the concept is based on a revolutionary new idea. Thanks to a sophisticated ventilation system controlled via sensors, 2226 utilizes the natural energy emissions of its occupants, equipment and lighting. The architecture was carefully adapted to ensure this flow of energy. The result is a well-conceived and perfectly proportioned building measuring 24 x 24 x 24 meters that is warm and comfortable all year round. The name 2226 refers to temperatures between 22 and 26 °C, which are accepted worldwide as being comfortable. A consistent solution executed at a high technical level and a self-confident statement for sustainability."
