High Performance Site Office at Wetherill Park

Multiplex has long understood the impact high performance buildings can have on its occupants – from commercial buildings that boost staff productivity to hospitals that assist patients to heal.

With up to 80 per cent of its workforce primarily based onsite, Multiplex saw an opportunity to apply its knowledge of high performance buildings to site offices.

Multiplex’s first high performance site office was established at the Stockland Wetherill Park project, with the onus put on Site and Project Managers to determine how high performance principles could be best applied to their project.

Flexibility and collaboration were identified as key requirements, so their site office was designed to provide individual and team zones as well as quiet and private zones with WIFI technology throughout. High importance was also placed on features including access to nature, views and daylight, thermal comfort, temperature and ventilation and occupant control.

BOSSA – Australia’s first standardised and independent post-occupancy evaluation system for offices – was used to test the impact of the new site offices. The survey showed:

  • 82 per cent regarded their productivity as being positively influenced by the new environment
  • 88 per cent also indicated their health was positively influenced by the environmental changes
  • 83 per cent were satisfied with the comfort levels.

Using its findings, Multiplex has developed a High Performance Site Shed guide which has been awarded an Innovation Point by the Green Building Council of Australia.

“We were really pleased though perhaps not surprised by the positive results. We know the impact smart design can have on people in terms of productivity in offices, wellbeing in hospitals and learning in schools. With 80 per cent of our workforce based onsite we wanted to apply this thinking to site offices,” said Dennis Else, Executive Director Sustainability, Health and Safety at Multiplex.
