Frequently Asked Questions

 A NatHERS energy rating assesses the thermal performance of a home and provides a star rating from 0 to 10 stars. The assessment considers factors such as the building design, orientation, insulation, glazing, construction materials and shading to estimate the heating and cooling energy needed to maintain comfortable indoor conditions.


New homes generally need to demonstrate compliance with applicable energy-efficiency requirements as part of the building approval process. Depending on your state or territory and project type, this may involve a NatHERS assessment, Whole of Home assessment or another approved compliance pathway. Our assessors can review your project and advise on the appropriate assessment.


A 7-star NatHERS rating indicates a high level of thermal performance, meaning the home requires less energy for heating and cooling than a lower-rated home in the same climate. Under NCC 2022, new homes are generally required to achieve a minimum 7-star NatHERS thermal performance rating, subject to the requirements applying in each state or territory.


Achieving 7 stars depends on the overall design rather than one individual feature. Orientation, insulation, window size and performance, shading, building materials, thermal mass and air movement can all influence the final rating. If your initial design does not achieve the required rating, our assessors can identify practical changes that may improve its thermal performance.


Turnaround time depends on the size and complexity of the project and whether all required documentation has been provided. We understand that energy assessments are often required to keep building approvals and projects moving, so we aim to provide a fast and responsive assessment service. Contact us with your plans and project details and we can provide an estimated turnaround time.


The cost of a NatHERS assessment depends on factors such as the size and complexity of the building, the number of dwellings and the documentation available. We offer competitive pricing and can provide a quote after reviewing your project plans and assessment requirements.


For most NatHERS assessments, we will need architectural drawings containing sufficient information about the building design and construction. Based on NatHERS technical notes the minimum design documentations required are:

  • Site Plan
  • Floor Plan(s)
  • Elevations
  • Sections
  • Construction Material details
  • Electrical schedule
  • Window, Skylight, and Door Schedule
  • Appliances, Solar panel, Battery and Pool specifications

 Additional information may be requested depending on the project.


Yes. If the initial assessment does not achieve the required rating, we can review the design and identify areas where thermal performance may be improved. Depending on the project, this could include changes to insulation, glazing, shading, window specifications or other building elements.


Energy-efficiency requirements for extensions and renovations vary depending on the project and the state or territory in which the property is located. Different compliance pathways may also be available. Contact us with your plans and project location and we can help determine the assessment services applicable to your project.


A NatHERS Whole of Home assessment considers the energy performance of major household systems in addition to the home's thermal performance. This can include heating and cooling, hot water, lighting, appliances, solar PV and batteries where applicable, providing a broader assessment of the home's overall energy performance.


BASIX applies to certain residential developments in New South Wales, including new homes and particular alterations and additions. The requirements depend on the type and scope of development. We can review your project and assist with the BASIX assessment and certification process where applicable.


Ideally, contact us during the design stage rather than waiting until the project is ready for approval. Assessing the building earlier provides more opportunity to improve its thermal performance and incorporate necessary changes before the design is finalised.


We provide energy efficiency and NatHERS assessment services across Australia. We are based in Canberra and have extensive experience with ACT requirements, with our accredited assessors also holding ACT Building Assessor licences. For projects in other states and territories, we provide our services in accordance with the relevant accreditation, documentation and regulatory requirements applicable to each location.


Simply send us your project plans, project location and a brief description of what you require. We can review the information, confirm the appropriate assessment service, provide a quote and let you know what additional documentation may be needed.
