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 façade 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 façade 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.

1 Bligh Street – Sydney’s first high rise office tower to incorporate blackwater technology

1 Bligh Street – Sydney’s first high rise office tower to incorporate blackwater technology
DEXUS and co-owners DWPF and Cbus Property announced that NSW Water Minister, Phil Costa today awarded the first combined private network and retailer’s water recycling licence to the 1 Bligh St development, making it Sydney CBD’s first high rise commercial office tower to incorporate blackwater recycling technology.
Minister Costa said construction is under way on a recycled treatment plant in the basement of the new development to treat waste water for use in the building’s toilets and cooling towers.
“This licence is the first of its kind to be granted to a Sydney high rise and will save 100,000 litres of precious drinking water a day,” Minister Costa said.
“This licence, granted under the Water Industry Competition Act 2006 is part of a NSW Government strategy to secure Sydney’s drinking water by attracting private investment in recycled water projects.”
Under the project:
- Wastewater is mined from the nearby sewer main and the base building
- Wastewater will then be treated to the highest standards approved by NSW Health at the recycled water plant in the basement
- Water is then distributed around the building for non-drinking purposes, with 75,000 litres used for cooling towers and 25,000 litres will be used for flushing toilets.
“Recycling is an important part of our Metropolitan Water Plan to secure Sydney’s drinking supplies, along with key initiatives including desalination, water efficiency, and dam upgrades,” Minister Costa said.
“It is vital we attract private investment into water recycling to ensure we meet our target of recycling 12 per cent of Sydney’s water needs by 2015.
“This project will reduce the volume of wastewater being pumped to Bondi and entering the ocean.”
The 1 Bligh Street development is co-owned by DEXUS, DEXUS Wholesale Property Fund and Cbus, and being built by Grocon. Aquacell will build and operate the recycled water infrastructure.
Aquacell CEO Colin Fisher said the granting of the licence is an important part of a sustainable future for NSW. “Recycled water schemes like this will ease pressure on water, energy and land as our population increases – this legislation ensures ongoing management is robust and a level playing field is achieved. Only organisations that meet the highest standards can be issued a licence which streamlines the approval process for future schemes. We are really honoured to be the first company to be granted the licence.
We plan to add other sites in NSW to our licence, which will open the way for developers to access private sewer and recycled water schemes where they are urgently needed.”
DEXUS CEO, Victor Hoog Antink said: “Consistent with the co-owners commitment to sustainability. 1 Bligh Street has been designed to be the next generation in high performing sustainable office space, incorporating world leading technology and design innovation. We are delighted to be announcing today another key milestone in 1 Bligh Street’s development with the awarding of the new blackwater recycling licence; a first for Sydney and the first high rise office building in the CBD to incorporate this leading technology”.
Grocon CEO, Daniel Grollo said the company’s core value of sustainability was being embraced with the incorporation of blackwater sewer mining on 1 Bligh St. “Water is a precious resource and its preservation is being achieved through the use of this system. This system provides 100% recycled water for toilet flushing, as well as 90% of cooling tower makeup water – thus demand on the water infrastructure is drastically minimised. It has been great to work with DEXUS/Cbus Property and Aquacell on this initiative.”
NSW Minister Costa said the 1 Bligh St development will be opened in May 2011.
“We have some of the largest recycled water projects in Australia under construction or online across greater Sydney and we are on track toward the Metropolitan Water Plan target of producing 70 billion litres a year by 2015,” Minister Costa said.
“Water efficient devices such as taps, showerheads and washing machines, and Water Wise Rules will help save up to 24 per cent of Sydney’s water needs by 2015.
Metropolitan Water Plan key initiatives include:
- $119 million on deep water storage from Sydney’s dams providing up to an extra 10 per cent, providing Sydney with 6 months supply in extreme drought;
- $30.5 million has been spent on recycled water projects across greater Sydney towards the target of providing 12 per cent savings by 2015;
- $1.9 billion on the Desalination Plant to provide up to 15 per cent; and
- $26 million on almost 1 million rebates and offers helping to save up to 24 per cent by 2015 along with educational campaigns and our new Water Wise Rules.

Greetings all.
HERE IS A WAY TO SAVE ENERGY
We are associated with bringing into Australia a Swiss designed product by company Fostac international. This product will reduce your buildings energy consumption, or increase solar energy output by a guaranteed 15% to 25% and a claim of up to 40%.
The priciple of operation is to “reorganise” the electromagnetic field produced around a conductor and secondly it increases the efficiency of the electron flow
In your ‘state of the art’ building, this may not only just be a perfect fit, but a real coup d’etat for your design team if it proved suitable, so if you you would like to investigate this product, give me an hour of your time, and we can discuss in greater detail.
