NatHERS software tool providers must ensure the accuracy, consistency and credibility of their tools.
Tools are accredited by the Nationwide House Energy Rating Scheme (NatHERS) and are built on a framework of technical requirements. These requirements cover everything from how data is entered and modelled to how results are validated against the benchmark tool.
Software providers must follow clearly defined protocols, calculation methods, climate data rules and software update processes to maintain accreditation.
This section brings together Nationwide House Energy Rating Scheme (NatHERS) specifications and technical information, guidance on software development, integration as well as training and support resources.
