Our Capability Statement

Designing and developing energy efficient structures has taken priority in planning efforts over the past several years.

Per the National Construction Code, new structures and add-ons to existing buildings must achieve at least a minimum 6 star energy rating on the NatHERS scale.


Benefits of Achieving a 6 Star Rating and Higher

However, while a 6 star rating is the minimum, the scale goes all the way up to 10 stars — representing an exceptionally well-designed property that can remain comfortable year-round.

Increasing the star rating of a property or design you plan to can have measurable impacts on annual electricity costs.

Additionally, such an improvement can lead to an overall reduction in the property's carbon footprint. Together, these improvements allow Australia to push forward as a leader in sustainability which is indeed, a positive outcome.

Achieving these ratings takes care and planning, however undertaking a thorough NatHERS assessment in Brisbane is key to both reaching the desired 6 star rating and creating the possibility for additional improvements. An improvement of even just one extra star can contribute to clear savings over just one year of operation.

At Certified Energy, we field a team of university-trained professionals to make a careful assessment of your design. Through extensive state of the art computer modelling, we can identify areas of improvement while opening the door to ways for increasing the value of your properties and promoting a healthier environment in which to live.

Understanding your NatHERS assessment in Melbourne

It is important to recognise that a NatHERS report does not evaluate the appliances or actual consumption of energy within the dwelling. Instead, this is a theoretical modelling of the way homes respond to seasonal changes in outdoor temperatures.

These thermal fluctuations can cause increased power draw as occupants seek comfort by heating and cooling the space. A 0-star rated home showcases very poor insulation from the outside. On the other end of the spectrum, a 10-star property robustly resists interior temperature changes no matter the outside conditions. Thus a 6 star rating is comfortably average.

Your assessor examines many aspects to each room to create an accurate digital picture of the space and its thermal conditions. By examining the plans your architects created, we can see where to make improvements for efficiency, be it altering or adding windows or changing the layout of the interior. All these options and more will be in your complete report.
