1 Bligh Street, Sydney – the next generation in sustainable architecture

1 Bligh Street, Ingenhoven Architects + Architectus

With the completion of 1 Blight Street, Ingenhoven Architects + Architectus in collaboration with the Dexus Property Group, have delivered Australia’s highest rated Green Star Building in Sydney.

Winner of the 2012 National Architecture Award, the building is the first high-rise tower to receive the highest six star certificate of the Australian Green Star environmental rating system.

The Building is visually spectacular. Ingenhoven Architects + Architectus have raised the bar defining the direction of future office building, at least for the next decade.

The organic nature of the building is unmistakable. Stepping into the atrium is like stepping into the belly of a whale. The large space is open and ribbed with each level following the perimeter the building. The curves and flow of the floors echo the organic form of an upended whale allowing the imagination to soar all 28 floors/ ribs. The central balconies form the spine and look like vertebrae while the glass lifts shoot up and down like corpuscles in the vascular system.

“The attention to detail and architectural integration of sustainable features has provided Sydney with a world-class commercial building that is setting new standards in sustainable architecture for high-rise buildings.”

The architects have broken with the traditional idea of the office block and removed the core, opened the internal space and allowed continuous views across floors creating a less confined work space. Having done this, it has also flooded the internal spaces with light and created an internal light filled atrium and public space.

There is also the use of intelligent materials such as high transparency glass, and concrete to create the subtle palette of the building interior and exterior, the careful orientation on the site, the use of movable walls and a double skin exterior that all help the natural flow of light.

And did I mention the views that extend across the harbour? These views extend from the core of the building to the outside. There is a constant exchange of internal and external elements.

Behind the visible and more obvious features of the building is its unified composition that marks a significant leap forward in design and planning. Included are the ‘Tri-generation’ heating, cooling and power system that works with the naturally ventilated spaces and the double skin façade (to create shade in the heat of the day and open in the evenings).

The waste water treatment and recycling system can reduce water consumption with an efficiency of up to 90% and has a capability to recycle much more than just the waste water produced within the building, while the computerised management system ensures the building’s consistent and high performance in all areas.

Ingenhoven Architects + Architectus have created an exceptional project. It is more than a building; it has helped build a cultural attitude toward building. It is the next generation of sustainable office design.
