Pollutant emission and dispersion can also be simulated in order to predict both the environmental impact of emissions emanating from buildings and the effect of air pollution on the air quality inside the building. Applications of building Aerodynamics simulation with Computational Fluid Dynamics (CFD) to Architecture, Engineering and Construction (AEC) design include:
- Wind load calculation
- Pedestrian wind comfort and safety studies
- Site planning
- Outdoor air quality assessment
Les Docks – Wind of comfort and safety
Simulation of airflow around buildings
Pedestrian wind comfort and safety
High-rise building aerodynamics
CFD analysis of complex fluid dynamic interaction of high-rise buildings
Twisted high-rise building aerodynamic design (ongoing)
The Council on Tall Buildings and Urban Habitat (CTBUH) defines a twisting building as one that progressively rotates its floor plates or its facade as it gains height. The aim of this project is to study the wind flow structures around a twisted high-rise building and the impact of design choices on it. Results from numerical simulations will be compared to those obtained for a non-twisted overlapped building that will be used as a reference.
Mesh generation for building Aerodynamics: challenges, best practices and lessons learned
Wind comfort and safety on a building terrace (France, confidential location)
Computational fluid dynamics is a powerful tool to investigate how wind affects particular areas of a building, such as terraces, balconies, passages, courtyards, in order to guarantee the appropriate level of comfort and safety. Engineers’ expertise is fundamental to identify the architectural elements which can have a significant role in the analysis of the airflow around and inside these areas. On the basis of accurate CFD results, BuildWind engineers are able to suggest innovative or convenient solutions to mitigate possible fluid dynamic issues.
