Advanced and Robust Analysis of Wind Effects
Advanced and Robust Analysis of Wind Effects
We are pleased to announce that Windtech’s Head office in Sydney was selected this month among 4 finalists for the NSW Export Awards. At about the same time, Windtech Consultants was also selected as a finalist for the Master Builders Association Export Awards. These awards are a testament to Windtech’s enviable reputation around the world, which was built on decades of research and development to enable us to deliver the most advanced instrumentation and analysis techniques for the study of wind effects on large structures. This combined with our high level of service makes us an obvious choice when there is a need to carry out a wind tunnel study to measure the wind effects on tall buildings and large structures.
Over the past couple of years the number of skyscrapers being built in Australia and New Zealand have comfortably doubled. Today’s most ambitious designs are bigger, taller and because of that they need to deal with the wind environment a mile or so above ground. The latest building designs also seem to be thinner in an effort to save space but the thinner the building is the more efficiently it has to deal with strong gusts of wind without affecting the people inside. This is why it becomes important for designs or concepts to be put through a thorough wind tunnel test to test every aspect of its durability.

At Wind Tech we use the load response correlation which was originally devised by Dr Michael Kasperski and Dr John Holmes to study wind loads on today’s long span roof structures. This is a state of the art approach used to study the overall effect that wind has on structures like these. Projects like the Nanjing Stadium which was the center of attraction at the China Games of 2005 was investigated by Wind Tech to ensure that it could bear the required wind loads. For more dynamic structures, Windtech can also determine the effect of the resonant response.

Skyscrapers have become the most common structures in big cities like Melbourne and Sydney. Some of the largest skyscrapers work as landmarks with larger ones being planned over the next few years. However, cities like Sydney are known to be windy even at particularly calm days down below. High rise constriction workers will tell you that the wind above even during summer can be chilly and very powerful, so it’s obvious that the wind effects the building too. However, as engineers continue to push the boundaries of what is possible the effect of wind on a structure becomes more important which is why wind tunnel testing is so crucial.

Windtech prides itself in the loyalty, capability and commitment of its entire staff and is delighted to announce the promotion of four of its senior engineers to the level of Associate Director.
Aaron Lefcovitch
Aaron is the Regional Manager for Asia and is based at our Singapore office. He has the prime responsibility of providing support in the field of Wind Engineering to clients throughout the Asian Region. Aaron studied Aeronautical Engineering at the University of Sydney (Hons. I), Aaron has extensive experience in the various facets of Wind Engineering and has worked on a significant number of low and high rise developments in South-East Asia, as well as in various cities throughout Australia and the Middle East. His extensive experience covers various desktop studies including for Masterplans. Aaron also has expertise in the study of solar glare impacts.
Adam Brownett
Adam has been responsible for the management of our internal quality control system and has extensive experience in the study of façade cladding pressures, wind-induced structural loads and building accelerations as well as various types of environmental studies. Adam has also undertaken numerous desktop wind and solar light assessments, including daylighting. Since joiningWindtech in 2004, Adam has worked on over 1000 high-rise tower and large span roof projects throughout Australia, Asia and the Middle East including Master Plan studies. Adam graduated in Aeronautical Engineering from the University of Sydney (Hons I).
Kevin Peddie
Kevin has demonstrated innovation in the formulation of treatment strategies for pedestrian wind environment impacts, remediation of wind entry, stack effects and wind-noise. Kevin has a particular interest in natural ventilation modelling, and leads Windtech’s research and development in this field and has presented at a number of international conferences in this area. Kevin has undertaken various masterplan studies and has also been an adjudicator for design juries to assess performance of alternative designs with regards to wind effects, natural ventilation and solar light effects. Kevin has a Masters and Bachelor of Engineering – Aeronautical (Hons I).
Dr. Nicholas Truong
Nick manages Windtech’s research and development team and has substantial experience in the various aspects of wind engineering both in terms of desktop and tunnel studies, having undertaken numerous such studies since joining Windtech in May, 2008. Nick graduated from the University of Queensland with Bachelor of Engineering (Mechanical and Space) (Hons I) and from MagdalenCollege, University of Oxford with a DPhil (PhD) in Mechanical and Medical Engineering. Subsequently, he was a research fellow and part-time lecturer at the University of New South Wales studying fluid-structure interactions.
