Grocon has been awarded a 6 Star Green Star – As Built v3 rating for its restoration of the heritage Legion House.

The building was constructed by the YWCA in 1902 and operated as a women’s hostel and outreach service for 60 years. Today, it is a five-storey A Grade commercial office space.

The building is part of Grocon’s high-profile Liberty Place development, and the first refurb designed to meet the Australian Sustainable Built Environment Council’s definition of a zero carbon building.

Key to this is the inclusion of gasification system that will use recycled woodchips from approved recyclers and recycled paper sourced onsite from the tenants within ANZ Tower, enabling the building to run independently from the power grid.

As previously mentioned in The Fifth Estate, there had been hurdles with the gasification technology, though a Grocon source said a new system would soon be operational.

Other sustainability technology that helped snag the 6 Star rating include vacuum toilets, timber from recycled sources or sustainably managed forests, the re-use of recycled bricks from demolished areas, and a high thermal performing curtain wall facade.

A Grocon statement said the sustainability outcomes were due to the spirit of collaboration amongst key stakeholders, including the City of Sydney, architects fjmt, engineers Umow Lai, investors GPT Group, ISPT and LaSalle, and long-term tenant St James Ethics Centre.

“Legion House stands today as our second zero carbon building, and is another example of how we can tackle the pressing issue of reducing carbon emissions in the construction industry,” Grocon chief executive Caroline Vinney said.

“It is a testament to the high calibre project team, and their vision to achieve lasting outcomes, that the 6 Star Green Star rating was achieved.”
