The energy factory

The Umwelt Arena is an exhibition and event platform for products and services for a modern, ecofriendly lifestyle. It is a Plus Energy Building (PlusEnergieBau PEB) as it produces twice its energy demands. The roof has an octagonal plant with 33 different surfaces, differently oriented, and with a slope from 6° to 62°. It almost stretches down to the ground, in the manner of a dome and it is completely covered with PV modules.
