Window Energy Rating Scheme (WERS)

The Window Energy Rating Scheme (WERS) provides a scientifically-based, fair and credible rating system for the assessment of window products for their energy efficiency performance. WERS is accredited by the Australian Fenestration Rating Council (AFRC) and adheres to AFRC protocols and procedures for the rating of windows and glazed doors. Energy Ratings provided by WERS are third party certified to the AFRC requirements, compliant with the National Construction Code (NCC), and able to be used to meet Regulatory requirements.

WERS is available to members only and provides exclusive information, benefits and tools with regard to all areas of window energy ratings. The resources include compliance certificates which can be generated to provide validity of a product to clients. Other information can also be accessed which would provide more insight on technical areas as well as Regulatory requirements.

WERS offers:

  • A service to all members for uncertified 'What-If Scenario' (WIS) energy ratings.
  • The evaluation of the combined Existing WERS rated Framing Systems (excluding generic windows) with any glass option from the International Glazing Database (IGDB).
  • WERS provides members the ability to research the performance values of different glazing options in their framing systems before having them fully simulated.

The WERS WIS results are uncertified and will need to be fully audited before they can be used to prove compliance to the NCC. To have a WERS WIS conducted, fill out the WERS What-If-Scenario Request Form with relevant information on framing systems and glazing types. Please note that if you wish to have a WIS conducted on a proprietary framing system not owned by your company you must seek approval from the proprietary system owner.

The results from a WIS are uncertified and unable to be used for compliance until they have been fully audited and accredited to AFRC protocols and procedures. WERS can arrange certification on a cost recovery basis as detailed below.

WERS Complaint Handling Procedure

For WERS to maintain a high level of service to its members the Complaint Handling Procedure document highlights the response, timeline and reports to be followed in the case of a member, non‐member, consumer or other agency identifying a possible problem within the results displayed on the certified products directory listed by WERS.   It is important that each member reads and understands the process that needs to be followed when an error is noted within the certified product listings. There are a number of different actions that can be taken in order to investigate, resolve or remove any erroneous product ratings.
