Building Better Homes: The benefits of a 7-Star Energy Rating.
Energy-efficient homes aren’t just environmentally friendly—they’re also more comfortable to live in and can significantly lower your heating and cooling costs. In Victoria, the minimum energy efficiency standard for new homes has been raised from 6 to 7 stars as rated by NatHERS (The Nationwide House Energy Rating Scheme). Starting from May 1 2024 all new homes must meet the new 7-Star energy rating under the amended National Construction Code 2022 (NCC 2022).
How is a 7-Star Energy rating achieved in your new home?
Achieving a 7-star energy rating involves integrating multiple energy-saving features that work together to enhance your home’s overall performance.
Why should I install solar panels for my home?
Installing solar panels on your home allows you to generate your own renewable energy, reducing dependence on the grid and saving money on your utility bills for years to come.
Enhanced Insulation
Homes with a 7-star rating feature superior insulation in the walls, ceilings, and floors. This creates a well-regulated indoor environment, minimising the need for extra heating or cooling.
High-Performance Windows and Doors
Double-glazed windows, insulated frames, and special glass coatings enhance energy efficiency by addressing the areas where homes typically lose heat or allow it to enter.
Energy-Efficient Appliances
In a 7-star-rated home, appliances are designed to use minimal energy without sacrificing performance. From air conditioners to refrigerators, these appliances ensure your home runs smoothly and efficiently.
Water-Saving Fixtures
Energy efficiency isn’t limited to power usage. Water-saving fixtures, such as low-flow taps and showerheads, help cut down water consumption, contributing to overall resource efficiency.
Key Benefits of NCC 2022 and a 7-Star Energy Rating
The National Construction Code 2022 is the minimum standard ensuring all buildings in Australia are safe, accessible, sustainable and durable. The introduction of the updated 7-Star Energy Rating in Victoria is an essential requirement to meet the livable housing design amendments.
Lower Energy Costs
The higher energy efficiency standard reduces the amount of energy required for heating, cooling, and lighting. Over time, this leads to lower energy bills and significant savings.
Improved Year-Round Comfort
Enhanced insulation and air sealing create a stable indoor temperature, keeping your home warmer in winter and cooler in summer, making it a more pleasant place to live.
Reduced Greenhouse Gas Emissions
Victoria has set climate goals, including reducing emissions by 45–50% by 2030 and achieving net-zero emissions by 2050. Residential buildings contribute 11% of Australia’s emissions, and improving home efficiency can help meet these targets while reducing your own energy bills.
