Top Tips for Achieving a 7-Star Energy Efficient Home in Perth

Building for 7 Stars: Top Tips and Guidance

Building a home that meets the 7-star rating under the Nationwide House Energy Rating Scheme (NatHERS) doesn't have to be costly or complex. By focusing on smart design choices and material selection, you can achieve a high energy efficiency rating and create a comfortable, sustainable living space.

Home Energy Ratings Made Easy

Understanding NatHERS

The Nationwide House Energy Rating Scheme (NatHERS) provides a flexible framework for assessing the energy efficiency of home designs. As of October 2023, new minimum standards will be introduced across most states and territories in Australia, making it crucial to start with strong design and orientation principles.

Importance of Early Assessment

Engaging a NatHERS assessor early in the design process is essential. Accredited assessors have the training and tools to optimize home designs for energy efficiency. By addressing potential issues early, such as the placement of windows or the choice of materials, you can avoid costly adjustments later on.

Design Elements to Consider

Windows and Glazing

Windows are a critical component of a home's energy performance. Double or triple glazing and appropriate coatings can significantly improve energy efficiency. Custom windows tailored to your climate and specific needs will yield better results than default options.

Zoning and Insulation

Internal zoning, such as adding more doors to create separate areas, helps in better managing heating and cooling. Insulation is equally important—consider increasing the R-value of your wall, floor, and ceiling insulation. Including insulation in areas like under slabs, garages, and internal walls can also improve your home's overall rating.

Practical Tips for Achieving 7 Stars

Colour Choices and Ventilation

The colour of your roof, walls, and window frames can impact your home's thermal performance. Lighter colours reflect more heat, which is beneficial in warmer climates. Additionally, installing ceiling fans in all rooms not only enhances comfort but also improves your NatHERS rating.

Efficient Lighting and Ventilation

Minimizing ceiling penetrations like downlights and opting for continuous ceiling insulation can boost your home's energy efficiency. Consider alternative lighting solutions that allow for better insulation coverage.

Conclusion

Achieving a 7-star energy rating is easier than you might think. By working with a NatHERS assessor from the outset, making informed design choices, and selecting the right materials, you can create an energy-efficient, comfortable, and sustainable home.
