Wind prevails, particularly in Gothenburg. The wind shapes trees and bushes along the barren west coast, where people built their shelters and structures to meet the forces of the wind. Today, wind engineering is an emerging discipline that increasingly contributes to the design of our built environment from the envelope of skyscrapers to the public spaces of our cities. In architecture streamlining expressed the heroic ethos of the 1930’s echoing the sweeping advances in aviation of the age. Now, we must build our environment with a minimal footprint and deal with the consequences of climatic change.
Thus, a smart aerodynamic cross section of a tower can replace tons of structural steel – in a world where severe storm events occur with rising frequency. At the same time, wind powers more and more of our energy consumption while expanding our awareness of the complex phenomena that steer the convoluted relationships between the forces in the atmosphere and the structures of our built environment.
These days, the Gothenburg Karlatornet (Karla Tower) gradually grows into the sky to become the tallest building in Scandinavia. Designed and engineered by SOM and VBK along with a large team of collaborating companies the tower deals with the increasing forces of wind in its high elevation. To overcome the effects of the wind new knowledge is provided from aeroelastic modelling of load bearing structures to aerodynamic design of leeward and comfortable urban spaces.
The webinar will address the advances in the research of wind design and engineering and practical application in the built environment by leading practitioners and researchers contributing within the field.
