Windtech are proud to be have provided the wind engineering and other services for all categories that involve tall buildings:

  • Australian Development of the Year (5 Martin Place Sydney by Dexus/CBus)
  • Best Office Development (5 Martin Place Sydney by Dexus/CBus)
  • Best Residential Development (Era Chatswood by Mirvac)
  • Best Mixed-Use Development (Pacific Bondi Beach by Rebel Property Group/Capit.el Group)
  • Best Sustainable Development – Existing Building (5 Martin Place Sydney by Dexus/CBus)

Windtech undertook a range of wind engineering studies for the development at 5 Martin Place. During the planning approval phase a study of pedestrian comfort was completed which included the wind conditions of the elevated terrace of the 10th floor as well as a study of the solar light reflectivity impact of the new façade of this development. This was followed by wind tunnel studies of the wind loads on the structure and cladding. This structure is particularly sensitive to the wind loads due to the fact that a significant portion of the base of the tower cantilevers over the existing heritage podium building. A wind entry study was also undertaken for the main lobby entries as well as an assessment of wind-noise and design wind loads acting on the artwork attached to the external facade.

The Era Apartments development located at 7 Railway St, Chatswood, is the final stage of the Pacific Place development by Mirvac. Windtech provided the wind engineering services for all the towers within this development precinct.

Windtech undertook a comprehensive pedestrian wind environment study for all the outdoor areas associated with the entire Pacific Place precinct as well as all outdoor areas within and around the Era Apartments development, including the various balconies. Windtech worked closely with the design team at Mirvac to ensure that all wind mitigation measures also contribute to an improved aesthetic for the affected outdoor areas and public spaces. Mitigation measures for the north-western balconies also improved thermal comfort performance off the adjacent apartments. Windtech also modelled and advised regarding the natural ventilation performance for all the apartments as well as the design wind loads on the structure and facade. The potential for wind entry at the main entrance as well as wind noise and lift pressurisation within this apartment tower was also modelled and appropriate mitigation measures were incorporated into the design. Windtech also assessed and advised on solar access to the apartments, shadows as well as solar light reflectivity impacts.

Pacific Bondi Beach is located directly opposite Bondi Beach and is exposed to both the prevailing southerly and north-easterly winds. This development is a conversion of the Swiss Grand Hotel Suites into residential apartments and incorporates an additional above the original building envelope. Windtech advised regarding wind entry as well as the design wind pressures for the extension.
