the result of a collaboration between stuttgart-based practice behnisch architekten and pohl architekten from erfurt, germany, the ‘speedskating stadium iznell – max aicher arena’ has received an award for the best sport building of the year from the world architecture festival. similar to a cloud, an undulating white canopy has been placed upon an existing venue to upgrade the facility for this year’s world single distant speed skating championships. accommodating 7,000 spectators, the space offers a flexible internal program to host international competitions and training. measuring 200 meters long and 90 meters wide, the clear-span high-performance roof is supported at the outer edge producing a column-free interior.

the form provides energy and economical benefits with a ‘low-E’ membrane which has been stretched between the timber and steel trusses to reflect the cold thermal radiation of the ice back down to the surface of the track maintaining a low temperature. the translucent material also diffuses natural daylight which enters from a series of seventeen north-facing skylights.

a continuous band of perimeter windows provides vistas of the bavarian alps while passersby may also see the activity occurring inside. technical plants and changing rooms are placed below the arena while existing ancillary buildings for administrative offices, workshops and storage were renovated to optimize sustainability.
