NCC 2019 Section J

23 MARCH 2020

As of the 1st of May 2020, the new National Construction Code (NCC) 2019 Section J requirements come into regulatory effect with the end of the twelve-month ‘discretionary’ transition period. This revision of Section J introduces a number of enhanced thermal envelope energy efficiency requirements which will influence architectural design. Previously accepted solutions, systems and approaches may no longer be compliant.

To assist our clients in understanding these changes, specifically the impact on architectural design, Lucid has prepared a series of concise and informative technical notes. These distil the changes down to what specifically relates to your designs.
