When an Energy Rating Index (ERI) is used to demonstrate IECC compliance using Section R406, the ERI “shall be determined in accordance with ANSI/RESNET/ICC 301”, which requires the use of ‘approved software rating tools’.

Use the links above to confirm the software tool listed in permit application documents are ‘approved’.

Additionally, for an ERI to be determined in accordance with ANSI/RESNET/ICC 301, “approved inspectors”, “approved testers”, and/or “certified raters” are required and must be approved by ‘approved rating providers’. A link to approved providers is here.

Individuals ‘approved’ for performing energy ratings in accordance with ANSI/RESNET/ICC 301 can be found here.

Accredited rating software tools provide the calculations necessary to produce a home energy rating. The requirements to be an accredited rating software program are defined in Chapter Three of the RESNET HERS Standards.
