An introduction to wind climate assessment on urban area

The quantification of the complex wind dynamic around high-rise buildings can answer questions concerning life quality, security and the development of the surrounding area.

Wind tunnel, pedestrian comfort and digital simulations

Never before have architects and engineers had a chance to be so creative when designing a new building. Economical and technical advances have allowed them to build unimaginable shapes and forms. Designing buildings is a complex business, influenced by many different aspects. And we are here to say: aerodynamics must be one of them!

That’s because shape, size, orientation and vicinity of a building can alternate the wind flow in a favorable or unfavorable manner for pedestrians. Increased wind speed can create a dangerous environment for the elderly or infants, but reduced wind speed can also lead to insufficient exchange of air.

That’s where the wind study comes to picture. The quantification of the complex wind dynamic around high-rise buildings can answer questions concerning life quality, security and the development of the surrounding area.

So understanding and optimizing the design according to aerodynamic concepts is the key to create a safe and comfortable urban environment. When was the last time you’ve listened to what the wind has to say about your design?

Traditionally, in building engineering, physical wind tunnel experiments have been used to measure the wind speed. But thanks to technology and advances in computational power digital simulation has emerged as an important tool in enhancing our understanding of fluid motion and offers the potential to serve as decision support in urban planning.

Wind simulations can provide detailed information of the fluid flow which is difficult to measure by experiments, and it offers the possibility for large-scale studies and sensitivity analysis.

Are digital simulations replacing physical facilities? At Ingrid Cloud we believe digital simulations are expanding the usage of numerical simulations and making it more accessible and efficient. Physical facilities are important for some projects and usually during validation phase. Digital simulations are faster and can be used in a bigger range of cases.

That said, let’s see to a real example of how a wind climate assessment can guide architects and engineers from the very early design phase?
