Prefabricated building technology delivers surprising sustainability benefits.
Over the past three years, we have been working with a prefabricated panel building methodology called Velocity. Developed by Mirvac and CSR, this has enabled us to cut construction times drastically on homes built within the masterplanned community business, and increase safety and efficiency along the way.
While we were aware of the improved quality and time savings Velocity delivers, we were curious to see how it stacked up in terms of carbon intensity. So this year, we conducted an LCA on a typical three-bedroom home at our Brighton Lakes project in New South Wales, comparing the Velocity wall technology to traditional building methods. This involved an assessment of all of the components and the assembly requirements for the house, at every stage of the home’s life cycle.
This was largely due to a major reduction in raw materials and waste generated by traditional construction methods on-site. The study also showed that a house built using prefabricated wall panels requires less water and transport.
Initial results also allowed us to identify some opportunities to improve Velocity even further, for example, reducing the use of cement and zinc-coated products.
Of course, the advantages of prefabrication don’t stop there. The reduction in manual handling required also provides a safer working environment for our employees and contractors, something that’s of paramount importance to us. And with 54 Velocity homes completed to date and a further 120 to complete over the project’s lifetime, we believe that the benefits of using a prefabricated panel system will just keep getting better.
