Queensland’s commitment to sustainable living is reaching new heights with the introduction of a 6-star energy standard for houses and townhouses. As of May 1, 2024, a remarkable 7-star energy standard for homes and units will come into effect. But until then, the mandate is clear: all new houses and townhouses must meet a minimum 6-star energy equivalence rating, emphasising energy-efficient design. In this article, we’ll explore the implications of this standard and why installing solar panels is a smart move for new house builds.
Understanding the 6-Star Energy Standard
The 6-star energy standard isn’t just another regulation; it’s a significant step towards a greener, more comfortable, and cost-effective living environment. This rating is determined by the design of the building’s shell, encompassing elements like the roof, walls, windows, and floors. A house designed to meet this standard is not only more energy-efficient but also provides ongoing savings by reducing the need for artificial cooling and heating.
Achieving the 6-Star Energy Rating
Meeting the 6-star energy rating involves thoughtful design considerations, including:
- Northern Orientation: Ensuring living rooms face north to maximize natural light and warmth.
- Minimising East and West Exposure: Reducing the area of east and west-facing walls and windows to minimise heat gain.
- Natural Ventilation: Incorporating windows and doorways for effective natural ventilation.
- Shading Solutions: Employing wider eaves and awnings to shield against harsh sunlight.
- Insulation: Installing insulation in the roof space and walls for temperature control.
- High-Performance Glazing: Utilising energy-efficient windows.
- Light-Coloured Surfaces: Using light-coloured roofs and walls to reflect heat.
- Ventilation: Providing proper roof space ventilation.
- Moreover, it’s crucial to consider the climate of your location when designing for energy efficiency.
Harnessing Solar Power
While meeting the 6-star energy rating is essential, forward-thinking homeowners are going a step further by embracing solar power. Solar photovoltaic (PV) energy systems are a perfect match for the Queensland sun. Here’s why they make sense:
- Clean, Renewable Energy: Solar panels harness the abundant Queensland sunlight to generate clean, renewable electricity.
- Reduced Energy Bills: By producing your electricity, you can significantly reduce or even eliminate your energy bills.
- Environmentally Friendly: Solar energy reduces greenhouse gas emissions, making your home more environmentally responsible.
- Increased Property Value: Solar-equipped homes are more attractive to buyers and can fetch higher resale values.
Optional Credits for Solar PV Systems
Queensland’s energy standards also offer optional credits for photovoltaic (PV) solar energy systems, which can be applied towards meeting the 6-star minimum standard for houses and townhouses. To qualify for a credit, the solar PV system must have a minimum capacity of 1 kilowatt.
However, it’s important to note that the optional credit for solar PV systems will cease on April 30, 2024, as these systems will be included in the Whole of Home assessment.
The Flexible Path to a 6-Star Home
Achieving a 6-star energy rating is achievable through various pathways. Whether it’s a 6-star building shell rating, combining a 5-star building shell with an outdoor living area, or incorporating a photovoltaic (solar) energy system, there’s flexibility to suit your preferences and budget.
Queensland’s new 6-star energy standard is a significant milestone towards more sustainable living. Embracing solar power not only helps you meet these standards but also ushers in a new era of energy-efficient, cost-effective, and environmentally friendly homes.
