Experience

Tony has 30 years’ combined experience as both researcher and consultant in wind engineering including 26years with Windtech Consultants since its establishment in 1991. His postgraduate studies were on the subject of Reliability of Wind Tunnel Simulations. His research experience includes a sensitivity study of the various parameters that affect wind tunnel results and has published a number of papers on this subject. Prior to this Tony had researched the interference effect of neighbouring buildings on wind-induced vibration of tall/ slender buildings.

Tony Rofail has undertaken and supervised over 2,500 wind engineering studies including wind tunnel investigations for various high-rise buildings, large roof and stadium building projects around the world, including many landmark projects.  Over the past 15years, Tony has developed innovative techniques in the study of the dynamic response of tall buildings that exhibit complex modal behaviour as well as the effect of rigid structural linkages between tall buildings

Tony is also able to provide unique innovative solutions to complex wind environment problems that do not adversely impact the architecture. Tony also has significant experience in the design and modelling of natural ventilation, wind noise, air quality, solar reflectivity, wind loads on façade elements, wind loads on ventilated facades, interference excitation of all buildings, design and commissioning of dampers for tall buildings and has presented at many conferences on these topics. Tony has assisted in legal cases as well as in the development of planning controls for a number of local government bodies.


 

AARON LEFCOVITCH –DIRECTOR


Qualifications and Professional Memberships

  • E. (hons) Aeronautical Engineering (University of Sydney)

Experience

Aaron has over 10years’ of combined professional engineering experience comprising of 1 year in the aerospace industry as a structural engineer and more than 9years’ in wind engineering.

At Windtech, Aaron spent a number of years in the Sydney office as a project engineer before being promoted as manager of the Singapore office in 2010, to provide support to the Asia and MENA regions.

During his tenure he has demonstrated an ability to develop and strengthen the capabilities of core staff while leading and growing the business globally from a technical and operational point of view. He has either lead and/or assisted in the delivery of more than 500 projects across the board spectrum of technical services that the company provides, including wind induced structural loads studies, façade cladding pressure studies, pedestrian wind comfort studies and solar glare impact studies.

Aaron has taken a particular interest in solar glare analysis techniques and has developed software that can simulate glare impacts of buildings and structures on pedestrians, drivers and occupants of neighbouring buildings. This software has the capability to quickly and accurately assess glare impact from complex building forms as well as assist in formulating mitigation strategies for potential glare impacts during the early design stage.

In addition to being involved on projects from a technical perspective, Aaron has had extensive experience in providing support to Windtech’s clients across Asia and the MENA regions.


 

ADAM BROWNETT –DIRECTOR

Qualifications and Professional Memberships

  • E. Aeronautical Engineering (Hons) (University of Sydney)
  • Member, Australasian Wind Engineering Society (AWES)

Experience

Adam is responsible for running the Projects team for Windtech globally and is an Associate Director of Windtech Consultants. He graduated in Aeronautical Engineering from the University of Sydney (Hons) and has over 12 years of consulting and wind tunnel testing experience.

Adam has extensive experience in wind tunnel testing for high-rise towers to determine the wind-induced structural loads and building motion effects. The analysis includes accounting for the effect of wind-load transfer associated with complex and linked-building structures, including multi-core developments. Furthermore, Adam has undertaken numerous wind tunnel studies to determine the design loads for the façade cladding of large building projects, as well as determining the level of pedestrian amenity due to wind affects in critical outdoor areas.

In addition to high-rise towers, Adam has also worked on determining the wind-induced loads on long-span roof structures such as stadiums, aircraft hangars, warehouses, and concert halls. This includes the complex load transfer interaction of the roof structure to further optimise the design of the project, and fatigue life analysis of critical elements under cyclical wind loading stress.

In addition, Adam is actively involved with the design of Tuned Liquid Damper systems to mitigate excessive wind-induced building motion in high-rise towers. This includes the development of complex damper systems where space constraints are limited within the structure. He is also involved with the detailed design and testing of large scale models of damper systems used to verify and optimise the damper performance prior to detailed design and installation within the project.

Adam has also carried out numerous solar studies of proposed and existing developments to assess the amount of potential visible glare from the façade. This also includes determining the amount of solar access and natural daylighting available within a building for commercial areas and dwellings overshadowed by surrounding built forms.


 

DR NICHOLAS TRUONG –DIRECTOR

Qualifications and Professional Memberships

  • PhD(Oxford), B.E.(Univ of Qld)
  • Corporate Member, Engineers Australia (MIEAust)
  • Member, Australasian Wind Engineering Society (AWES)

Appointments

  • Standards Australia Committee BD6-002 Wind Actions on Structures.
  • AWES Committee for the Wind Loading Handbook

Experience

Dr Nicholas Truong is a professional engineer with over 15 years of consulting, research and development experience in the field of fluid dynamics and wind engineering. Prior to joining Windtech in 2008, Dr Nicholas Truong was a research fellow and part-time lecturer at the University of New South Wales studying fluid-structure interactions and continues to supervise research students in the area of fluid mechanics from time to time. His research experience includes the experimental testing of gas and liquid flows, the design of experimental and testing equipment and the numerical analysis of large data sets.

Nicholas’ particular interest and experience is in the use of wind tunnel testing to study and design the response of unusual structures under wind loading, as well as in the field of air and liquid fluid-structure interaction mechanics. He is also responsible for Windtech’s ongoing innovation, research and development program to maintain Windtech’s position as a global leader in the field of wind engineering.

Nicholas has undertaken and supervised wind engineering studies including wind tunnel investigations for various high-rise buildings, large-span roof structures, stadiums, statues and masts around the world. These include numerous landmark developments. Nicholas is also a leader in the testing and analysis of wind loading and aerodynamic stability of bridges, including cable-stayed, arched, pedestrian and suspension bridge designs. This includes the initial design analysis during the concept design phase to assess aerodynamic stability. He also oversees the development and testing of static and aero-elastic bridge testing to determine the aerodynamic performance of the bridge.

Wind climate analysis is a critical aspect in the accurate analysis of wind loading on any structure. Nicholas also leads the climate analysis group at Windtech, who provide detailed analyses of wind speed and directional probabilities as well as seasonal variations in the case of thermal comfort studies. His analysis includes both micro and macro climate analysis.
