Lean is green
Save on construction costs, spend more on sustainable design.
That was Calibre and JCY Architects’ aim when collaborating on the Jervis Rise apartment complex, which won UDIA Western Australia’s Affordable Development Award in Perth this week.
As civil and structural engineer for the project, Calibre played a critical role in minimising construction costs. The savings meant the developers, BGC Development and Access Housing Australia, winners of the UDIA award, could redirect funds towards JCY’s solar-passive design.
“Calibre worked with JCY Architects from an early stage to find cost-savings to help ordinary people enjoy the kind of sustainable design you see in new luxury homes,” said Nick Pike, assistant project manager of urban development.
Calibre worked with architects to develop supports and structures that were just as effective as those in preliminary designs, but more economical.
Calibre also engineered the above-ground space, including utilising the landscaping design, to cope with more stormwater. This minimised the need for below-ground storage and thereby reduced costs for earthworks and drainage infrastructure.
Apartments in the 51-unit, three-storey building cost between $280,000 and $379,000. They are a high-quality, affordable alternative to detached housing in the growth suburb of Baldivis, located about 10 kilometres southeast of Rockingham, Western Australia.
Judges for the UDIA award commended the “simple, well-planned design” and its “impressive attention to detail”. The building achieved a six-star rating and is low-maintenance, meaning lower strata fees.
The judges applauded Jervis Rise’s optimal solar orientation and good cross-ventilation — features that would make apartments affordable in the long-term by cutting running costs.
Apartments are angled to capture winter sun, minimise summer sun and allow owners to control airflow effectively — three features that combine to dramatically reduce energy use for heating and cooling.
Included in the range of apartments are accessible homes for people with disabilities. Access Housing is retaining 12 of the apartments, including the accessible apartments, for affordable rental properties.
“It’s a fantastic project socially and environmentally,” said Mr Pike. “Construction cost savings have contributed to a greener building — and ultimately more money in residents’ pockets.”
