5 things about wind simulations a real estate developer has to know

1. Being in harmony with wind can save you millions

Wind simulations and wind tunnel experiments can give architects and structural engineers crucial insights to their concept. That’s why it’s best do to them at the earliest stage of the design process. For the Chinese skyscraper, Shanghai Towers, for example, optimizing the design from a rectangular to a twisted shape reduced wind loads by 24% saving $58 million worth of building material.

2. If outdoor safety is a must, wind comfort analysis is a must, too

High-rise buildings act like funnels, squeezing large volume or air into smaller spaces, causing the wind to accelerate on ground level. This Downwash Effect can be dangerous for pedestrians. In 2011, 120 km/h wind gusts around the Bridgewater Place Tower in Leeds, UK, blew a truck on top of a sidewalk killing a pedestrian. With so many accurate and affordable wind simulations solutions available today, wind studies in urban projects are no longer ‘optional.’

3. Wind Simulations are way more affordable than you think

Ingrid Cloud automated process applies geometrical heuristics to create an initial mesh, which is then refined only where necessary. This is a unique Ingrid Cloud feature! Guided by a posteriori error estimation in wind load prediction, the adaptive algorithm constructs local error indicators that decide what cells in the mesh must be refined to optimize the mesh.

This is the final result of a wind simulation produced with Ingrid Cloud software. The model shows Niigata City, in Japan.

4. Bad wind performance will affect the ROI of your development

The return from the real estate investment is based on the price the owner can charge for the rent. If shop or restaurant owners begin to lose customers and revenue due to low levels of pedestrian comfort, the demand for the commercial real estate will drop, so will the rent price, and the overall value of the property. There are examples of urban wind comfort failures in almost every big city. They often go unnoticed. When a business property is not performing well, hardly anyone checks if the pedestrian wind comfort may be the reason.

5 . Wind Simulations are not only “a skyscraper thing”

The majority of new buildings being built today are between 35 to 100 meters tall. Those structures cause a significant impact on the urban microclimate. High rise buildings shape the outdoor comfort all over the world, making a significant impact on solar radiation and wind speeds.
