This project by HASSELL has done more than achieve a 5 Star Green Star accreditation; it has raised the bar for public buildings.
Located directly above the underground railway station in the heart of Perth’s CBD, the design of one40william was founded over five principals: workplace, public realm, climate, context and the environment.
Not made to be apparent in the look and feel of the building, one40william’s main focus was on sustainability, principal of HASSELL, Dirk Collins, told BPN.
“The sustainability is a basic part of the design. It’s built into it. It’s integrated, and it’s a part of the building fabric,” says Collins.
“So, the sustainability was a core aspect of it. Not to build a building and put a layer of fancy bells and whistles over the top. It was innate,” he says.
Recycled materials used throughout the project include steel which was used for concrete reinforcement, and post-consumer reused timber for the formwork, flooring and wall finishes and external pergola structures.
During construction a recycled waste management plan was implemented which included minimising PVC content by 30 per cent, using 100 per cent post consumer content for 60 per cent of building steel, and creating dedicated construction waste sorting and recycling procedures. The judges say one40william represents a new type of public building, one that manages the demands of the public realm at lower levels and a private office building above.
“The built form shows articulate planning to utilise passive design responses such as self-shading and the maximisation of the use of natural light to its users,” the judges comment.
