The Results

High-Performance Energy Outcomes

The building attained a remarkable 6 Star NABERS Energy rating—the highest possible level and the first apartment building in Western Australia to achieve this milestone at the time. This accomplishment was based on a blend of grid and rooftop solar-generated electricity.

Water Efficiency

In addition, the building secured a 5 Star NABERS Water rating, showcasing its commitment to efficient fixtures and responsible water usage.

Significant Cost Savings

Residents benefit from reduced energy costs compared to the standard grid supply, with potential savings of up to 30% annually.

Resilience

The system's black start capability ensures that the building can operate off-grid during power outages, enhancing its resilience.
