One Energy Team – Best Value

Fast, insightful and guaranteed solutions

Energy compliance is perfectly positioned to handle any sustainability request.

We work with architects, developers’ design teams and Councils across Australia to obtain compliance, minimise construction costs and

maximize comfort levels.

We illustrate our energy reports for ease of understanding.


We perform more iterations to reduce your construction costs.
We illustrate added insulation for ease of design and construction communication.
We use realistic design assumptions to better resemble actual building performance and save construction costs.
We use 3D building modelling tools used to achieve the best quality control.


Quick Turnaround

Quotations – Same business day of inquiry.
Deemed to Satisfy (DTS) reports – Within 1-2 business days.
Energy Rating – Within 2-3 business days.
Performance Solutions – (JV3 & Reference Building method) – 1 to 2 weeks.


If we can’t reduce your construction cost by more than our fee, we’ll only charge 25% of our full fee.


Every day we assist architects and project managers to COST EFFECTIVELY comply with Section J of the National Construction Code.

If we cannot reduce your construction costs by more than our fee, we will only charge 25% of our full fee – that’s how confident we are!


Approximately 80-90% of a typical residential building’s energy demand is thermal related (i.e. heating and cooling), so it’s critically important to obtain a professional energy assessment. We offer cost-effective energy efficiency measures allowing you to comply to the code while conserving energy.

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!


Everyone claims to be cost-effective. We provide a Service Guarantee:

We believe that our service can reduce construction costs and that the cost-saving will far outweigh our service fee. GeoFlow guarantees that our energy assessment service will reduce the building construction cost more than the value of GeoFlow’s 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 the best proof of how cost-efficient our performance-based solutions are. You won’t get this guarantee anywhere else.

  • Quotations – Same business day of enquiry.
  • Deemed to Satisfy (DTS) reports – Within 1-2 business days.
  • Energy Rating – Within 2-3 business days.
  • Performance-based solutions – (JV3 and Reference Building method) – 1 to 2 weeks.

We spend more time drilling deeper and iterating potential solutions, to reduce critical construction costs.

We spend more time to use realistic design assumptions in our modelling so that the results more closely resemble real-life building performance and save construction costs.

We utilise Innovative 3D building modelling tools to achieve the best quality control.

We deliver superior energy reports:  Building plans are marked-up to show the proposed changes, saving the architect and/or builder considerable time.  Amended cross-section drawings are provided for each effected type of wall, roof and floor.

GeoFlow 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 materials 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 GeoFlow 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 method.  Compliance to Building Construction Code – BCA section J or Section 3.12 can be achieved

In cases where compliance is cost-prohibitive, GeoFlow will first discuss the energy options that you may be open to, and we can implement all the options, one by one, to assist you to make an informed decision.

The following sample list outlines a range of energy measures that Geoflow applies to achieve a cost-effective compliance that satisfies the client’s energy efficiency targets
