Towards wind modelling for sustainable building/urban design

Abstract

Abstract In view of climate change and resource depletion the analysis of wind impact on built environment could be used for conscious building/urban design protecting humans against high winds but also taking advantage of wind forces in terms of ventilation of spaces or production of wind-driven energy. There is a strong need of developing the modelling technology that would enable predictive studies in this field. Climate change mitigation and adaptation became the point of departure to introduce the notions of risk/chance analysis that could help to examine the architectural/urban design from the holistic perspective. The need of addressing different parts of wind velocity spectrum is acknowledged. The steps forming the process of design for sustainable wind environment are listed. Both the necessary test activities, and the simulation ones, as well as, the ones leading to the application of risk/chance assessment are discussed. Wind thresholds referring to different aspects, levels and scales of studies should be examined. They constitute the boundary of the uncertain set of expected acceptable solutions. In some cases, probabilistic model of thresholds could be considered. Joint project within the Digital Twin Cities Centre (DTCC) at Chalmers is referenced, where the newly established Vinnova Centre of Competence could offer the platform for the development of new modelling technology.
