With Australia continuing its journey towards greater energy efficiency, the recent updates to the National Construction Code (NCC 2022) bring significant changes that impact how homes are designed and built. Builders and homeowners must now meet a 7-star energy rating under the Nationwide House Energy Rating Scheme (NatHERS).
Let’s explore the key changes to NCC 2022, what they mean for homeowners, and how the required 7-star energy rating can be met through Aluplast uPVC windows from Premier Windows.
What’s Changing in Australia’s Energy Efficiency Standards?
The NCC 2022 introduces several significant changes designed to boost energy efficiency in new homes. They are part of Australia’s broader initiative to reduce greenhouse gas emissions and promote sustainable building practices nationwide. Let’s break down the key points:
When And Where Will These Changes Take Affect?
Builders have until mid-2024 to fully comply with these new standards, allowing time to adapt. The NCC also recognises that Australia’s diverse climate zones require tailored energy efficiency standards, so exact regulations will vary depending on the location of your home.
What This Means for Western Australia
In Western Australia, these updated energy standards mean builders and homeowners must adjust their construction approaches. The state’s diverse climate—from the hot, dry north to the more temperate south—brings unique challenges:
Designing for Local Conditions:
Homes in different parts of WA must account for local climate conditions. In Perth, homes should focus on reducing heat gain during the scorching summer months while retaining warmth in the winter.
Achieving the 7-Star Energy Rating:
To meet the 7-star energy rating, builders must incorporate enhanced insulation, energy-efficient windows, and thoughtful construction techniques, ensuring homes maintain thermal efficiency and reduce energy usage year-round.
Ensuring Whole-of-Home Energy Efficiency:
The new standards also require builders and homeowners to use energy-efficient appliances—such as heating, cooling, and water systems—that comply with energy consumption guidelines.
Enhanced Energy Efficiency with Premier Double Glazing: Meeting NCC 2022 7-Star Standards
At Premier, our double-glazed glass options offer a significant upgrade in performance compared to single-glazing without Low-E coatings, making them ideal for homes aiming to meet the new NCC 2022 7-star energy rating.
| Metric | Standard Glass | Premier Double Glazing | Saving |
|---|---|---|---|
| VLT | 85 | 74 | 13% |
| U-Value | 74 | 1.41 | 76% |
| SHGC | 0.77 | 0.38 | 30% |
* VLT = Visible Light Transmission
* SHGC =Solar Heat Transmitted
* U Value = Internal Heat Retention
Performance is based on 5+12+5 double glazing with Low-E coated glass, which comes standard in all Premier windows and doors.
Glass Efficiency Metrics
For instance, our standard clear double-glazing boasts a U-value of 1.41, providing much better insulation than single-glazing, which typically has a U-value of around 5.8. This results in less heat loss through windows, keeping your home warmer in winter and cooler in summer.
In addition to better insulation, our glass options have SHGC (Solar Heat Gain Coefficient) values between 0.38 and 0.54. SHGC measures how much solar heat passes through the glass—lower values mean reduced heat gain, which is especially useful in warmer climates, ensuring your home stays comfortable all year round.
Another essential metric is VLT (Visible Light Transmission), which refers to the percentage of natural light that passes through the glass. Our options range from 46% to 74% VLT, allowing you to choose how much natural light enters your space while controlling heat gain and energy efficiency.
In Summary
The new NCC 2022 energy efficiency standards represent a significant step forward in sustainable building practices. Energy-efficient windows help you comply with these regulations, lead to long-term savings, and enhance your home’s comfort.
By choosing uPVC double-glazing from Premier Windows, you’ll meet these new requirements and enjoy the many long-term benefits of superior window technology.
