NatHERS Principles for ratings in regulation mode: the existing Software Technical Notes have a new addendum.
NatHERS Software Technical Notes
The following NatHERS Software Technical Notes are designed to be living documents to ensure consistent thermal performance assessments of drawing sets for new residential buildings and major additions to existing residential buildings when using NatHERS software for regulatory purposes. These documents will be updated from time to time, and it is the responsibility of assessors to ensure they are using the current version. It is planned that both documents will be revised before the end of 2013.
The Technical Notes (including addendums) are to be used by all assessors accredited under the Nationwide House Energy Rating Scheme, unless other state or territory regulatory obligations apply. Where there is an inconsistency between a regulatory requirement for carrying out a thermal performance assessment or preparing a house energy rating, the regulatory requirement prevails to the extent of the inconsistency.
These research documents have been produced without web accessibility conditions.
