Inzell Speed Skating Stadium - Behnisch Architekten

Great example of an energy-efficient ice hockey / speed skating facility: Inzell Speed Skating Stadium.

Incorporating the skylights and other daylighting strategies without affecting the conditions of the ice—direct heat would soften the surface and slow down skaters—also presented a challenge to the project team. The group solved the facade problem with a roof overhang that provides shading from outside the glass facade, which also has a sunscreen printed directly on the glass with a gradient effect to diffuse whatever light is coming through. For the skylights, "We used advanced 3-D simulations to shape and position each [skylight] opening," says Leupold. The modeling resulted in 17 north-oriented skylights positioned to allow natural light into the arena without directly hitting the ice. These crescent-shaped portholes with ETFE glazing protrude up to 20 feet beyond the roof's surface. From above, they look like gills slit into the sleek white roof surface, formed by a re...
