Mirvac Osprey Waters Sustainable Demonstration Home & Sales Office
The Osprey Waters Sustainable Demonstration Home & Sales Office is an example of Mirvac’s progress towards their mission of having net positive environmental impacts by 2030. Designed by architect Sid Thoo, the project showcases exemplary performance and inspires future residents of the Osprey Waters masterplanned community, nested along the banks of pristine Peel Inlet.
This project demonstrate Mirvac’s aim for design excellence beyond NCC compliance, and includes improvement strategies such as dematerialisation for the building materials and renewable energy (solar PV for electricity and solar thermal for hot water).
High quality design differentiates this project from surrounding residences and extends the lifespan to 55 years by reducing redevelopment pressure in the near future. Higher design life means that all initial impacts are diluted over a longer period of time therefore improving the performance on a per year basis.
Materials and Construction
Optimised construction time (total of 16 weeks) resulted in less impacts from trade staff transportation to site. A careful selection of materials guaranteed higher thermal performance and durability, and lower maintenance requirements. Materials list included:
- Structural Insulated Panels (SIPs),
- Weathertex cladding,
- Light-coloured Bluescope Colorbond Roofing,
- Polar Double-Glazed Windows
- Polished concrete floors
The project was designed for reduced energy demand and included high thermal performance rating of 7 stars with ceiling fans as the cooling method, high efficiency LED lighting and solar hot water system with gas boost. After all energy efficiency measures were implemented, a large solar PV system of 5kW was installed.
Throughout the year, the house generates more electricity than it uses, therefore a net positive operational carbon performance. A total 107% operational savings compared to the benchmark.
