7 Star Energy Efficiency Guide for QLD

Window and Door Specification for 7 Stars

Your Guide to Meeting 7 Star Energy Ratings in Queensland

 

Under the NCC 2022 Energy Efficiency Provisions, all new homes and building permits issued in Queensland from May 1st, 2024, need to meet a minimum energy efficiency rating of 7 stars. Here we’ll help you understand how your windows and doors can assist you to achieve this, regardless of whether you’re building or renovating.

 

 

Climate Zones in QLD

Climate Zones in QLD

The Queensland coastal region (climate zone 2) is primarily a cooling climate, so it is most important that your Windows and Doors have a low Solar Heat Gain Coefficient (SHGC), as you want to prevent the heat from the sun from entering your house.

At the same time, climate zone 2 experiences mild winters, so having windows with a lower U Value is equally important. A lower U Value contributes to energy efficiency by minimising heat loss and reducing the need for heating in cooler seasons. In turn, this lowers energy consumption and associated heating costs.

 

 

 

 

Achieving greater performance with Stegbar

 

 

 

Energy efficiency exists on a scale, with cost and design preferences changing what you might choose for your home. Our Residential and Alumiere ranges are offering sufficiently low Solar Heat Gain Co-efficient (SHGC) coverage with single glazing in order to achieve 7 star performance, without the cost of a
double glazed solution.


The below shows our good, better, best offering.

RESIDENTIAL SINGLE GLAZED LOW-E

Take the first step into energy efficiency glazing by adding a Low-E coating to your glass. Low-E glass allows light to pass through while it reflects heat.

RESIDENTIAL SINGLE GLAZED LOW-E NEUTRAL

A better upgrade from Single Glazed Clear Low-E, this glass is coated in thin layers of metallic oxide when manufactured, which reflects radiant heat helping to
maintain a cooler interior.

RESIDENTIAL SINGLE GLAZED LOW-E GREY

Perfect for the Queensland climate and a step up in performance from Single Glazed Low-E Neutral, adding the grey tone to your selection will provide improved solar control and thermal insulation. Not only increasing your
thermal comfort, but also helping to reduce the fading of your furniture, carpet and other interior surfaces

RESIDENTIAL DOUBLE GLAZED LOW-E SOFT COAT GREY

Double glazing with Low-E, applied to the inside of the Grey toned glass, provides a significant improvement in the U value helping to retain heat in cooler months, and SHGC helping to prevent the heat from the sun entering your house in the warmer months.
