Integrated into our NatHERS rating process

When you get a NatHERS rating from Powerhaus Engineering, we include a customised Powerhaus dashboard built from your exact energy model. That means:

  • No extra spreadsheets
  • No confused clients
  • No need to wait on assessor feedback for every tweak
  • No approvals process panic
  • No extra fee (included in Designer packages and above)

You get a NatHERS rating and the ability to explore what it means, and how to get the most from it.

  • Powerhaus home optimisation session for high performance home design showing computer screen and hands operating controls.
  • Two Powerhaus employees running an optimisation session to help design a high performance home.

“This is the missing piece of the puzzle — it translates the design decisions into bang-for-buck.”

Where the Powerhaus app fits in your process

Step 1

Design onboarding

Share information about the building’s details and design vision so we can tailor our approach to your project.

Step 2

Preliminary star rating

We model your design’s thermal performance to provide an initial rating estimate, using NatHERS software.

Step 3

Optimise with data

Use the Powerhaus app to test different design choices and reach your optimal star energy rating.

Only available with the Powerhaus app

Step 4

Detailed consult

We guide you through compliance requirements while you focus on your creative goals.

Step 5

Fast certification

Once your design is finalised, we provide a NatHERS certificate for quick compliance.

Get Started

Have some questions?

Each state has different requirements for getting your home certified.

If you want to get your new build or renovation certified, meeting the requirements as early as possible in your plans will avoid costly revisions and wasted time down the track. Request a quote to get started with your home certification or give us a call to discuss your needs.

We have a range of packages to suit the needs of each project, tailored to the size and complexity of the project. Send us your project details and we will provide an obligation-free quote.

The minimum required energy ratings are changing around Australia. The new National Construction Code (NCC 2022) requires new houses to reach 7 stars energy efficiency. Each state will adopt this change at different times – read our summary of NCC 2022 adoption dates.

Your house energy rating measures how comfortable your house is and how much added heating and cooling it will need throughout the year to remain comfortable. The higher your star rating, the more sustainable, comfortable and bill-free your home will be.

That’s what we’re here for. We’ll identify all the options available to you to increase your house energy rating and reach the minimum required 6 stars, 7 stars, or your desired level of performance. 

In fact, we built Australia’s first home energy efficiency design app that makes reaching your house energy rating as simple as possible

We’d be surprised if they didn’t. That’s why we incorporate one round of changes into our quote. Further changes and updates are prioritised to help you get your approvals finalised as quickly as possible.

Houses built now will likely be around for another 50-100 years. By creating a high-rating house, you’re creating a long-lasting asset for the future. In addition, buildings with a high house energy rating can:


– Decrease energy bills and increase energy resilience
– Meet most of their energy needs through solar (and get off fossil fuels)
– Have better indoor air quality
– Remain healthy and mould-free
– Increase living comfort and resistance to extreme fire or rainfall

Yes! We love to help people build high-rating and high-performing homes. Our service for new homes includes access to our innovative energy efficiency design app, so you can identify the best ways to improve your design and house energy rating. 

“The less efficient a building, the greater the temperature difference between your skin and the temperatures of the walls, windows, doors, floors and ceilings. It is the temperature differences between you and the building which causes discomfort.” – Robert Bean

Generally, if your house is reaching around 7.5 to 8 stars, you will need very little heating and cooling to be comfortable. If comfort is important to you, we recommend reading how we can help make home’s more comfortable and resilient.
