Smart architecture: Using numerical modeling to calculate the danger of channeled wind on an urban development 

The Challenge

Engineering innovation and smart architecture has led to an exciting urban environment optimized for the needs of pedestrians and cyclists. Narrower access ways are possible, which also allows more efficient use of space as architects seek to go higher. A risk of these designs is that the wind can be channeled in a way that is potentially dangerous for both pedestrians and cyclists. The customer in this project wanted to ensure that this risk was minimized.

 

The Solution

Element generated a Computational Fluid Dynamics (CFD) model of the development and surrounding environment. A numerical modelling method, CFD allowed the accurate prediction of wind flow patterns between buildings, taking as input the local wind rose of prevailing winds, the development geometry and the surrounding geometry to provide an accurate atmospheric boundary layer at the inlet to the development. Variations in temperature and weather that occur during the year were also taken into account.

Using Computational Fluid Dynamics (CFD) in Architectural Planning

 

The Result

The model outputs enabled the team to generate a risk plot showing the likelihood of dangerous conditions occurring at every location in the development during the year. Some small changes to the design were recommended to mitigate this risk, and the end result was judged acceptable by the planning authorities.
