High-rise or particularly tall buildings can cause strong acceleration of the wind within the urban environment. Consequently, hindering the comfort and safety of pedestrians in public spaces, but also of owners and tenants in private outdoor spaces, such as balconies and (roof) terraces. This in turn affects the usability, value and safety of the building and its surroundings. Wind comfort assessments are becoming a standard part of a good risk analysis to ensure a profitable project and, often, the local governments demand an assessment as part of the building permit application (e.g. NEN8100 in the Netherlands, …. In London, .. etc.).
