Aspern Seestadt

One of Europe’s most innovative and sustainable energy efficiency projects

Vienna is one of Europe’s most popular and fastest-growing capitals – a challenge that the city on the Danube is turning into a virtue. It is employing smart ways to develop new residential spaces; in aspern Seestadt, for example, the technological planning was foregrounded and preceded structural work in selected buildings. The aim of this thoroughly digitalized approach: to prepare the grid for growing numbers of renewable sources and increase both the efficiency and lifespan of buildings. With success: Many smart districts around the world are already utilizing the insights developed in Aspern. By 2030, heat and electricity in the new development, which will be home to 20,000 residents, will come entirely from renewable energy sources.
