1 Bligh Street achieves world leadership 6 Star Green Star
Mon 29 Mar, 2010 Industry News
1 Bligh Street achieves world leadership 6 Star Green Star and highest rating in Sydney.
Co-owners of 1 Bligh Street DEXUS Property Group, DEXUS Wholesale Property Fund and Cbus Property today announced that the 1 Bligh Street office development in Sydney has been awarded a 6 Star Green Star Office Design v2 Certified rating.
1 Bligh Street has also been awarded the highest Green Star rating score in Sydney/NSW, which includes the maximum allowable five points for innovation in categories such as environmental design initiative and exceeding Green Star benchmarks.
DEXUS CEO, Victor Hoog Antink said “Every aspect of 1 Bligh Street, from Australia’s first high rise double skin facade to the unique full building height naturally ventilated atrium, is designed to optimise sustainability and tenant amenity throughout the 28 level development. As co-owners, we are delighted that our vision to deliver the next generation of sustainable office buildings has been recognised through the achievement of a world leadership 6 Star Green Star rating.”
The double skin faÃ§ade system is a major contributor to the 6 Star Green Star rating and allows the energy consumption of the building to be kept at a minimum, and facilitates the energy performance to be maintained at 5 Stars NABERS Energy levels with a 42% CO2 reduction when compared to a similar sized conventional office tower.
Other innovations which contributed to 1 Bligh Street’s leading score and sustainability credentials include:
the solar cooling system which feeds into the tri-generation system that reduces the strain on the CBD grid infrastructure by a further 25% and provides free cooling for the building
the specially formulated high strength concrete used and the column design which reduces the number of columns, and therefore minimises the amount of concrete used
the first use of a black water recycling in a high rise office building that will save 100,000 litres of drinking water a day, equivalent to an Olympic swimming pool every two weeks
state-of-the-art water efficient fittings, rainwater harvesting and fire system water reuse
all timber and plywood used in the structure is recycled or from FSC accredited sources
90% of all steel used in the project comprises more than 50% recycled content
80% of all PVC type products have been replaced with non PVC materials
Grocon CEO, Daniel Grollo, who is also a founding member of the GBCA, said he was proud that all involved had shown world leadership on this project. “This is a fantastic project in the centre of Sydney and symbolises a new way forward in sustainability features,” he said.
“The use of unique high strength concrete with a lower cement content means there is 5,768 tonnes less of carbon dioxide being released into the atmosphere and to date, we have recycled 37,000 tonnes or 94% of all construction waste produced on the project.”
Green Star is a comprehensive, national, voluntary environmental rating system undertaken by the Green Building Council of Australia (GBCA) that evaluates the environmental design and construction of buildings. The 6 Star Green Star Rating is the highest awarded by the GBCA.
“We congratulate the co-owners DEXUS Property Group, DWPF and Cbus Property for this world class achievement,” says the Chief Executive of the GBCA, Romilly Madew. “Achieving five innovation points (out of five) reflects that 1 Bligh Street is a truly ground-breaking green building. Following DEXUS’s 123 Albert Street in Brisbane receiving a 6 Star Green Star and DEXUS’s/Cbus Property’s pursuit for sustainability throughout their respective portfolios, 1 Bligh Street further confirms the co-owners’ commitment to sustainability and green building innovation.”
When 1 Bligh Street is completed in May 2011 the building will provide a new benchmark for sustainable office space. 1 Bligh will provide the highest levels of tenant amenity including spectacular views in all directions, in particular, the premium northern aspect over Sydney Harbour and Circular Quay.
The unique full height atrium and elliptical shaped floor plates enables 74% of the building to be within 8m of either the faÃ§ade or the atrium, providing large amounts of natural light into the building and spectacular views in all directions. Occupying a premium corporate address in the heart of Australia’s financial capital, 1 Bligh will be a striking new addition to the Sydney skyline.

Info from the architectus website-
The structure delivers consistent large floor plates of up to 1600m2 and achieves 92 per cent efficiency Nett Lettable Area to Floor Space Area.
Forty per cent of office space is within 4.5 metres of the facade with 1000m2 contiguous column-free space creating high potential for office layout flexibility. The elliptical plan is 12 per cent more efficient than a rectangular building in facade to floor area and allows excellent natural light penetration. The 120 metre high central atrium makes dynamic views accessible to all.
1 Bligh St - also known as Space - features a transparent elliptical shape
and double skin façade.

It's our preferred mode of operation and we have a long history of environmentally conscious buildings. It's just what we do.
We've been able to pursue innovative and holistic solutions in terms of the energy, sun shading and thermal comfort. In general we've had a holistic approach to the indoor environment quality.
There's a range of initiatives:
We're still in design, so obviously still working through the project. I guess we've got a very willing client but there's a disconnection between the end user for design purposes and the unspecified tenant that will occupy the building. This has two aspects.
Firstly, there's no ability to plug directly into the environmental aspirations of the would-be tenant when pitching to a wide market. In this case we may be missing opportunities if the actual tenants have very high aspirations.
Secondly, the performance of the design is largely dependent on the fit-out and how the tenants operate the building. Whatever you do in the base building is commendable but it comes down to the commitment of the tenants to achieve the star rating with the fit-out and use of the building. They may use a lot of air conditioning and be a power hungry tenant so it's very important the tenants are also educated. If you are going into a six star building then you want to have a six star fit-out. The building we're currently doing has the potential to be naturally ventilated, but, it is dependent on the fit-out from the tenant. The fit-out they choose could make the building fully air conditioned.
The biggest change has to happen in the property market. A big problem is the way the tenant's representative grade the buildings. Premium building standards require a a comfort band of 22-24 degrees Celsius and this needs to be discussed. It costs a lot of energy to achieve such a narrow band. A more realistic band would be, say, 22-26 degrees Celsius. This would save a lot of energy if the temperature outside is 35 degrees.

Space 1 Bligh
In the heart of Sydney’s traditional financial precinct and with views to Sydney harbour, this Premium-grade office building has been designed by Architectus, in association with Ingenhoven Architects, to combine the best in innovative technology and sustainability.
Space 1 Bligh will offer tenants the next generation in workspace design featuring a naturally ventilated, full-height atrium creating connectivity between floors. Other features include a large, sun-filled forecourt, entry hall and child care centre, a mid-level wintergarden and roof terrace.
The building comprises 42,000 square metres of floor space over 28-storeys with typical floors of about 1,600m2.
Space 1 Bligh has been designed to achieve a 6-star Green Star Rating and a 5-star Australian Building Greenhouse Rating (ABGR).
Contributing to Space 1 Bligh’s green credentials is its distinctive double skin façade design. The transparent facade comprises two layers of glass which are separated by a naturally ventilated cavity. The cavity contains adjustable automatic blinds to shade the internal layer of glass at critical times of the day, dramatically reducing solar heat gain and glare while maintaining harbour views.
Black water recycling, rain water harvesting for irrigation, gas generated energy for cooling, heating and electricity, and roof-mounted solar panels for electricity also contribute to Space 1 Bligh’s environmental rating.
The building is set to create a new benchmark in Australia for sustainable high rise and provide an enduring presence attuned to emerging cultural, social and environmental values.
