Dr Niall O’Sullivan has 10 years experience in CFD and environmental studies, a PhD in fluid-structure interaction using a combination of CFD and full-scale measurements and a Masters degree in Mechanical Engineering, where he studied wind tunnel design.

Prior to joining Windtech, Niall led CFD for environmental design, sustainability and mechanical engineering at a global architectural firm, working on numerous noteworthy projects and running countless simulations in the built environment.

Since January 2018, Niall has combined this extensive experience with Windtech’s wind tunnel data and has developed the Windtech methodology to further the accuracy and reliability of pedestrian comfort studies, natural ventilation modelling, thermal comfort modelling, thermal stack effect and double skin façade performance modelling, to name a few.

With CFD fast becoming the technology of choice for a growing number and range of projects it is now more important than ever that the right expertise is employed. Niall not only stays up to date with the latest in the industry, but also leads the way: he is on the committee for BS8579 (guide to design for balconies and terraces) and presents at international conferences as lead author.
