Wind Impact Assessment

Most medium to large scale developments require wind analyses that address comfort within amenities and surrounding adjacent land. For some, a desktop assessment may be sufficient. However, to meet criteria set by relevant authorities and to pursue the highest level of accuracy, testing in the wind tunnel is ideal. Especially if a development has any of the following:

  • A unique shape
  • Unpredictable wind exposures
  • Complex flow scenarios and wind loads
  • Predicted flow conditions that are well in excess of the recommended criteria.

Comfortable and safe conditions

For many of us, the wind conditions around a building are only noticeable when they’re unfavourable. Combining state-of-the-art technology with some of Australia’s best engineering minds, Vipac’s wind tunnel tests can help you understand the wind environment under a wide range of conditions and directions.

Wind tunnel testing enables an optimisation of shapes, surfaces, and protrusions with two major benefits; enhancing safety and comfort, and maximising design. Other capabilities include:

  • Quickly verifying the effectiveness of design modifications for wind control are
  • Polar plotting results from single-point data
  • Detailed information on wind speeds at all locations around the development
  • Flow visualisation and omni-directional wind speed sensor measurements.

Design guidance

After testing is complete, our wind engineers present the final report and work closely with the design teams to explain the wind effects and interactions observed. We interpret the data and help these teams incorporate the observations back into their designs — thereby maximising value. One notable example was on Lilli Apartments in Melbourne, where Vipac’s advice led to natural ventilation of the interior spaces, reducing the reliance on air-conditioning and reducing occupants’ energy bills.

Our team of experienced wind engineers can determine what assessment is relevant to your development and deliver comprehensive reports to facilitate planning approval. We work hand-in-hand with the design team to suggest controls and treatments that maintain the intent of the architect’s objectives.
