I can’t seem to find the Heating and Cooling loads for Zone 65 at Cargo NSW. The NatHERS list has n/a for that zone?
The ABCB Standard NatHERS heating and cooling load limits document clause 2.1 Limitations, indicates that the limits do not apply in NT, NSW, TAS, parts of QLD and WA. Accordingly n/a appears against those climate zones. In NSW the BASIX provisions apply.
