Energy efficiency is not just a trend but a necessity to protect the only planet we call home. With increasing energy costs and growing environmental concerns, achieving a 7 star energy rating for your home is a significant step towards sustainability. This rating ensures that your home is highly efficient in terms of energy consumption, leading to lower utility bills and a reduced carbon footprint.
In this blog, we will explore what a 7 star energy rating entails, the requirements to achieve it, and how double glazed windows and doors from Windows Tech can play a pivotal role in meeting these standards.
What is 7 Star Energy Rating?
In the pursuit of sustainable living, energy efficiency in homes has become a paramount concern. The 7 star energy rating is a benchmark that signifies a high level of energy efficiency in residential buildings. This rating is part of the Nationwide House Energy Rating Scheme (NatHERS) in Australia, which assesses the thermal performance of homes. A 7 star energy rating indicates that a house requires significantly less energy for heating and cooling compared to lower-rated homes, leading to reduced greenhouse gas emissions and lower energy bills.

What are the 7 Star Energy Rating Requirements?
Now that you know what a 7 star energy rating is, it’s time to answer the question “How do I achieve a 7 star energy rating house?”
This involves meeting several stringent requirements, like combining thoughtful design, high-quality materials, and energy-efficient technologies. Let’s take a deeper dive into these aspects below:
- Design and Orientation: Collaborate with architects and designers who specialise in energy-efficient homes. Ensure the house is oriented to maximise natural light and ventilation.
- Thermal Performance: The building’s design must minimise heat loss in winter and heat gain in summer. This involves using materials and construction techniques that enhance insulation.
- Building Envelope: The building envelope, including walls, roofs, windows, and doors, should be designed to prevent unwanted heat transfer. Be sure to seal any gaps or cracks in the building envelope to prevent air leakage.
- Glazing: High-performance glazing, such as double glazed windows and doors, is essential to reduce heat exchange. These are highly effective in preventing heat loss during winter and reducing heat gain in summer.
- Shading: Effective shading solutions like eaves, awnings, and pergolas to block summer sun while allowing winter sun to penetrate and warm the interior.
- Insulation: Opt for adequate and high-quality insulation in walls, ceilings, roofs, and floors to maintain a stable and more comfortable indoor temperature.
- Renewable energy: Installing rooftop solar panels to support energy usage.
- Energy-Efficient Appliances: Choose energy-efficient heating, cooling, and lighting systems. Be on the lookout for the Energy Star seal when shopping for appliances.

When Does 7 Star Energy Rating Start?
Back in 2022, an agreement was made to increase minimum energy efficiency building standards for new homes in Victoria. This was a leap from 6 to 7 stars to meet the changes to the National Construction Code 2022.
The implementation of the 7 star energy rating standard is a progressive step towards achieving Australia’s sustainability goals. Updated energy efficiency standards for new homes have a mandatory commencement date in Victoria of 1 May 2024. This initiative is part of the broader strategy to reduce energy consumption and greenhouse gas emissions in the residential sector.
To encourage people even more to walk down this more sustainable 7 star energy rating road, Victoria provides attractive rebates to registered builders and land developers to design and build 7 star NatHERS rated homes.
There are also rebates available to reduce the upfront cost of installing solar panels, solar hot water, and solar batteries. On top of that, there are incentives and interest-free loans for solar panels for existing homes and homes under construction.
How Windows Tech’s Double Glazed Windows and Doors Help Achieve a 7 Star Energy Rating
Windows Tech, a leading provider of high-performance windows and doors in Melbourne, plays a crucial role in helping homeowners achieve a 7 star energy rating.
Here’s how our double glazed windows and doors contribute to energy efficiency:
- Superior Insulation: Double glazed windows and doors consist of two glass panes separated by a layer of air or inert gas. This design significantly reduces heat transfer, keeping your home warmer in winter and cooler in summer.
- Reduced Energy Consumption: By minimising the need for artificial heating and cooling, double glazed windows and doors help reduce energy consumption, leading to lower energy bills.
- Enhanced Comfort: These windows and doors provide a more comfortable indoor environment by maintaining a stable temperature and reducing drafts.
- Noise Reduction: Double glazing also offers the added benefit of noise reduction, creating a quieter and more serene living space.
- Durability and Security: Windows Tech’s products are designed for durability and security, providing long-term value and peace of mind.
Investing in Windows Tech’s double glazed windows and doors is a smart choice for homeowners aiming to meet the 7 star energy rating requirements. Not only do these products enhance the thermal performance of your home, but they also contribute to a more sustainable and cost-effective living environment.
