700 Bourke Street

Case Studies

700 Bourke Street

In collaboration with client CBUS Property, tenant National Australia Bank (NAB) and architect Woods Bagot, Multiplex incorporated a number of innovations in the construction of 700 Bourke Street to build a better workplace for its occupants and the environment.

The building uses one of Australia’s largest chilled beam systems for climate control. Other sustainable features include blackwater recycling, rainwater harvesting, and rooftop-mounted solar panels.

Multiplex carried the focus on sustainability through to the construction, with up to 30% of the concrete used in the building’s structure recycled; sustainable recycled timber flooring and joinery used; recycled formwork used from previous projects, and over 80% of construction waste materials generated by the project recycled.

Now home to 6,000 NAB employees, 700 Bourke Street achieved a six-star Green Star rating and was named Australia’s top performing workplace in 2015.

The survey carried out by Sydney University and the University of Technology found that the building topped nine out of 13 Indoor Environmental Quality (IEQ) indicators: spatial comfort, individual space, indoor air quality, visual comfort, building image, productivity, work area comfort, building satisfaction, and health and maintenance.
