GIA offer High Resolution CFD Wind Analysis, providing a faster more flexible and potentially more accurate approach
With greater density in cities and buildings becoming taller to help meet targets for our growing population, microclimate assessments are an essential part of planning process.
GIA and VU.CITY working with Wirth Research, are providing Wind Microclimate Assessments, using Computational Fluid Dynamics (CFD) analysis to test and identify wind flows quickly and cost effectivly.
Skyscraper-affected airflow is a relatively new phenomenon in cities like London, Manchester and Leeds, which were historically mainly low-rise. But as anyone who has ever walked near a very tall building in the middle of a city on a windy day will have noticed the wind is often much more intense around the base of the tower.
Accelerated wind near skyscrapers is caused by the “downdraft effect”. This happens where the air hits a building and with nowhere else to go, is pushed up, down and around the sides. The air forced downwards increases wind speed at street level. And, if several towers stand near each other, there is an effect known as “channelling”, a wind acceleration created by air having to be squeezed through a narrow space.
CFD modelling provides highly detailed, fast analysis of existing and proposed conditions. This combination easily highlights any potential issues and provides commercial and innovative mitigation solutions saving clients considerable time and money
Wind Microclimate Assessments
We offer Wind Microclimate packages suitable for project stages covering early concept development through to planning sign off.
We make urban habitats more comfortable and de-risk the planning process through application of high resolution CFD modelling early in the design and planning process. Greater understanding of the urban habitat, earlier, allows the creation of more effective solutions developed in tune with the building.
CFD predict a buildings local airflow, and quickly highlights any areas of pedestrian or vehicular danger or discomfort. Making this analysis part of the design process, rather than an afterthought, we enable our clients to have greater control on their urban developments.
Our wind microclimate modelling can be scaled up to master planning levels and beyond, without jeopardising model resolution or results accuracy.
High performance computing infrastructure and highly developed CFD processes and methods provide accurate results in short turnaround times.
Modelling early on in the design process allows our clients to de-risk their planning by highlighting any potential issues providing commercial and innovative mitigation solutions for development
Wind Loads and Cladding Pressures
Wind loading and cladding pressure analysis using CFD leads to more aerodynamically efficient buildings, and provides reductions in building cost through reduced wind loading.
As with our microclimate analysis, we provide various levels of analysis to cover the project lifecycle, from concept development through to pre-building sign off.
