InSite with Dahlsens brings you practical pathways to compliance with Energy Lab
Brian Haines discusses the significant changes in energy efficiency standards for NCC 2022, focusing on achieving a seven-star rating. He explains the new heating and cooling load metrics, the impact of climate zones, and practical tips for builders to navigate these updates effectively while ensuring compliance with the new regulations.

The key changes in NCC 2022 in NSW are:
Introduction of new thermal comfort index requirements best fit for the NatHERS pathway.
Increased stringency in heating and cooling load metrics, with the addition of a total load metric that aligns with the seven-star rating.
A new total load requiremnet in NSW for compliance which directly corresponds to a seven-star rating on the revised NatHERS Star bands.
The adjustment of capped heating and cooling loads with special carve outs for NatHERS climate zones 9, 10 and 11 only.
The impact of climate zones has been intensified, with a closer alignment to microclimates, affecting the assessment results significantly based on location.
The cap on total load standard now limits the house design to a maximum of 7 stars, requiring specific attention to design, orientation, window performance, and insulation.
A new emphasis on the importance of window specifications, particularly U-values and solar heat gain coefficients, to achieve compliance.
There are new requirements for thermal decoupling of slabs, improved reflective roof cavities, and attention to the thermal impact of elements like skylights and cladding.
The software and assessment methods have been upgraded, with new tools available for more accurate evaluations and compliance checks.
These changes aim to raise the energy performance standards while encouraging better design practices and comprehensive assessments to meet the new regulations.
