Our point of difference

In the energy compliance market, we try to be the best in quality, fast delivery and of course, we guarantee our service!



We spend more time drilling deeper and iterating potential solutions, to reduce critical construction costs.
We utilise Innovative 3D building modelling tools to achieve the best quality control.
We deliver superior energy reports: illustrated, council-ready and easy to follow.

Service Guarantee

We believe that our service can reduce construction costs and that will far outweigh our service fee. If this is not the case, and the client wishes not to proceed with our report, then we will only charge our 40% deposit.
This is proof of how cost-efficient our performance-based solutions are. You won’t get this guarantee anywhere.

Energy Compliance

Energy Compliance team provides timely and competitively priced energy efficiency rating and compliance reports. We liaise with architects, building surveyors and project managers to:

  • Enable a wider choice of construction and architectural design ideas.
  • Achieve lower construction costs.
  • Reduce ongoing energy costs.
  • Deliver cost-effective, energy-efficient buildings.
  • Improve living comfort.
  • Achieve sustainability targets beyond the minimum code requirements.

While Energy Compliance offers all the usual avenues to satisfy energy compliance to code, we specialize in providing expert energy performance-based solutions (i.e. JV3 and Verification Using Reference Building).


When a client contacts us to obtain a compliance report/certificate for a new building, we will ask about their sustainability target and offer the most cost-effective compliance solutions to the code (i.e. Building Construction Code – BCA section J or Section 3.12)

In cases where compliance is cost-prohibitive, the Energy Compliance team will first discuss the energy options that you may be open to, then we implement all the discussed options, one by one, assisting you to make an informed decision.

The following sample list outlines a range of energy measures that the Energy Compliance team applied to achieve cost-effective compliance that satisfied the client’s energy efficiency targets.
