Real Estate Development and Paragliding

In our line of work we frequently deal with interactions between wind, the built environment and all the things in between: from shopkeepers that want their awnings to stay were they are supposed to, over cyclists that have a hard time driving through gusty wind to freezing pedestrians in train stations. In a first for us, we looked into the interaction between a real estate project developed by Wood Partners and pilot safety around the flight park of the Utah Hang Gliding and Paragliding Association (UHGPGA).

UHGPGA was concerned that the real estate development project would adversely affect wind conditions, especially at their main landing site, right next to the development area. Wood Partners on the other hand went out of their way to ensure that their project integrates well into the community and not only respects the history of the area as a flight park but is actively designed in a way that allows pilots to enjoy their hobby safely after building the project. The influence of landscape architecure on wind / turbulence is the critical design parameter - just the job for Rheologic!

Some members of UHGPGA with an engineering background provided excellent on-site wind information up to and including long-term wind measurements directly in the flight park, which allows us to tune our simulation to the exact wind conditions in the area (velocity, direction, gusts, surface roughness, …) for a high-fidelity representation of the wind situation.

The detailed wind and turbulence assessment for various wind directions, building configurations etc. - all of which are also available in an interactive 3D model in the browser (performant hardware needed, allow some loading time) - formed a basis for the stakeholders to discuss the best options in this participative planning process.

We are glad that our work could contribute to this participative urban planning process and would like to express our thanks to everyone involved for the engaging discussions, improvement proposals and all their energy and time that went into this!
