Vipac’s Wind facilities include computational fluid mechanics and two boundary layer wind tunnels where we conduct scale model tests on proposed developments.
We examine:
• Wind conditions for public comfort in outdoor areasWind tunnel testing of scale models is used to determine wind-induced facade cladding pressure loads. This is recommended for larger developments and those with unusual form or wind exposure to avoid under or over-design based on wind loads determined by standardised analytical methods. Without scale model wind tunnel testing, wind loads cannot be estimated accurately due to the randomness inherent in turbulent flows. Conservative load estimates can lead to significantly higher structural costs by requiring glazing, cladding and associated supporting structures to be of thicker gauge than necessary. Conversely, less rigorous load estimates may lead to structural failure.
