The Result
The Princes Terraces was officially opened in November 2017. The residences will use 50 percent less energy and potable water than a typical townhouse. The homes will also generate 55 per cent less greenhouse gas emissions compared to a standard home. Over the construction of the project, 230 local trades and suppliers supported the build. The handover process included continuous modelling and tuning of the Green Star criteria to ensure all systems performed as anticipated.
As a result, the ZEGO Insulated Concrete Walls were determined to have twice the thermal resistance of a standard brick wall, with an R Value of 4.0-5.07 with the average NatHERS rating of the dwelling is 7.2 Stars. Acoustic testing has also been undertaken as part of the Green Star “As Built” rating. This exemplar project also demonstrated that “Sustainability doesn’t mean costly” when building. It was idenitified that as a guide applying Green Star added approximately 6 per cent additional cost overall.
