- Owners and Builders
In line with the 2019 update to the National Construction Code (NCC) there are a number of updates that are planned for the Chenath engine, which improve accuracy of ratings and solve some long-lasting issues with the software. These include:
Guidance on how to use the new zones is currently being developed.
These updates will be accompanied by an updated Technical Note and an updated NatHERS Universal Certificate (which is also being updated based on the recent review that is available here)
An updated software accreditation protocol is also being developed to ensure these updates are rolled out uniformly to all tools.
