Split heating and cooling loads for NCC 2019

In addition to the above Chenath updates, you may be aware the Australian Building Codes Board (ABCB) recently sought feedback on changes to the NCC 2019 that would set maximum heating and cooling load limits for the NatHERS pathway in the NCC. The goal of setting maximum heating and cooling load limits is to improve the performance of new homes in Australia. The NatHERS Administrator is currently working through the implementation of this change and advice on any changes to assessments will be provided to assessors before changes become live. For more information about the work already undertaken on split heating and cooling load limits, have a look at the ABCB report.
