Public Drawing – Above the Wind Basin

  • Waldlabor
  • Within the Waldlabor forest, wind is scattered and diffused, slowed by thick trunks with deep roots anchoring trees and plants firmly into the soil.
  • Where the forest meets the Holderbach, the air descends along the steep riverbank to gather along the watercourse in its natural cycle, forming a colder, humid atmosphere. Emerging from the shelter of the woods, one crosses the Tobelholzbrücke, where this natural climate unfolds upon pausing.
  • Beneath the bridge, the soughing airflow narrows and gains speed before continuing downstream toward Affoltern, contributing to a better air quality as it reaches the more rigid city in the distance.
