Become a professional House Energy Rating Assessor

About Energy Assessors

NatHERS Accredited Assessors are professionally recognised energy assessors who are qualified in conducting house energy ratings using NatHERS Accredited Software.

In detail…

Nationwide House Energy Rating Scheme (NatHERS)  Star Ratings are conducted by professionals using purpose-built software  for a number of purposes, including:

  • To meet the mandatory energy efficiency requirements for homes and major renovations based on the National Construction Code
  • To advise home owners, architects and builders on the energy efficiency of various house designs
  • To advise prospective home buyers on the thermal performance of a home they are interested in buying

As a NatHERS Accredited Assessor, you will join the hundreds of other energy raters across Australia who are recognised as professionals in their field. You will also receive support to ensure that your home energy ratings are conducted in a reliable and consistent way.

You will provide essential skills such as:

  • thermal resistance and capacitance of building materials
  • window glazing values
  • occupancy patterns (including internal heat loads, typical occupancy times and occupancy behaviour)
  • window coverings (which are standardised for all ratings, noting they are likely to change of the life of the building)
  • different types of zones in the house and whether they are conditioned/unconditioned
  • thermostat settings (temperatures at which artificial heating/cooling is no longer required to achieve thermal comfort, noting this varies depending on climate zone)
  • local climate and weather (including temperature, humidity, wind and sun)
  • shadowing/overshadowing by adjacent buildings and features
  • size of the building being assessed (noting smaller buildings generally have a larger wall surface area than bigger buildings)

The Nationwide House Energy Rating Scheme (NatHERS) provides homes with a star rating out of ten based on an estimate of a home’s potential (heating and cooling) energy use. By providing a ‘measuring tape’ for energy efficiency, NatHERS helps to make Australian homes more comfortable for their inhabitants and help residents to save on energy bills through smarter design choices. Often good design can reduce the amount of energy needed to keep a home comfortable with no or little additional construction cost.

NatHERS is administered by the Department of the Environment and Energy on behalf of the states and territories.

NatHERS promotes the benefits of increasing thermal performance of homes, as this can often be achieved with no or little additional construction cost. Through its inclusion in the National Construction Code, NatHERS is used by state and territory governments to reduce the greenhouse gas impacts of residential buildings.

Requirements for Accreditation

How to become a professional NatHERS accredited House Energy Rating Assessor.

In detail…

To become and maintain accreditation as an accredited House Energy Rating Assessor  you must;

  • apply to become a member of an Assessor Accrediting Organisation (AAO).
  • have successfully completed the Certificate IV in NatHERS assessment (CPP41212) or Certificate IV in Home Energy Efficiency and Sustainability (CPP41119)
  • notify the AAO of any current or previous accreditation with another AAO
  • nominate to the AAO the software tools you will use
  • agree to be subject to a Quality Assurance (QA) review within their first 12 months of accreditation
  • agree that you will comply with AAOs Assessor Code of Ethical Practice
  • complete at least 12 CPD points in each year of accreditation, where one point equals at least one hour of time spent undertaking the CPD
  • maintain professional indemnity insurance commensurate with the volume and scope of the work they undertake
  • agree to conduct assessments in accordance with the latest NatHERS Technical Note, in compliance with your jurisdiction’s application of the NCC and using the NatHERS Universal Certificate
  • agree that you will conduct your Assessments in a way which ensures the health and safety of yourself, and others, so far as reasonably practicable and which complies with all relevant workplace health and safety laws in the Jurisdictions in which you operate.

In detail…

New entrants into the industry must now obtain a Certificate IV in Home Energy Efficiency and Sustainability qualification (CPP41119). Course details can be found by searching for the Certificate IV in Home Energy Efficiency and Sustainability or  “CPP41119” on the MySkills website.

The Certificate IV has a national focus, as it is recognised under the Australian Qualifications Framework, allowing assessors to work anywhere across Australia. Training organisations are able to deliver the course through the Vocational Education and Training system.

The current training providers in Australia offering Certificate IV in Home Energy Efficiency and Sustainability qualification (CPP41119) training to become an accredited NatHERS assessor are.

Accredited Software

The rating software tools accredited under the Nationwide House Energy Rating Scheme (NatHERS) are AccuRate, BERS Pro and FirstRate5.

In detail…

NatHERS house ratings use computer simulations to determine the potential thermal comfort of Australian homes on a scale of zero to 10 stars. The more stars, the less likely the occupants will need cooling or heating to stay comfortable.

There are four software tools accredited under NatHERS, each with different user interfaces and functions. If you are completing energy ratings in accordance with NatHERS methods, you will need to decide which tool best meets your needs.

Obtaining a NatHERS rating at the required star level is specified in the National Construction Code (NCC) (link is external) as one of the ways of demonstrating compliance with the energy efficiency (thermal performance) requirements for new houses and apartments.

There are currently four software tools accredited for use under NatHERS:

AccuRate v2.4.3.21

BERS Pro v4.4.0.2 (3.21)

FirstRate5 v5.3.0 (3.21)

HERO v1.1
