Climate & Energy in Mount Gambier
Climate zone 26 in Mount Gambier features cold wet winters with regular heavy frosts, cool springs and autumns, and warm but generally moderate summers. The Southern Ocean influence brings consistent rainfall throughout the cooler months and occasional cold snaps. Heating is the primary energy demand, with homes requiring effective insulation, high-performance glazing, and good draught sealing to maintain comfortable indoor temperatures during the long cold season. Northern solar access is critical for passive heating, as clear winter days provide valuable solar warmth that thermal mass can store for overnight release. The relatively moderate summer temperatures mean cooling demand is low, though climate change is increasing the frequency of warm summer days.
NatHERS Requirements
New homes in Mount Gambier must achieve the 7-star NatHERS minimum under NCC 2022 energy provisions adopted in South Australia from 1 October 2024. Zone 26 assessments heavily weight heating performance, evaluating insulation R-values, glazing thermal performance, draught sealing, and solar access. The Whole-of-Home assessment considers the efficiency of heating systems, which are critical given the cold climate and represent a major component of residential energy use in the region.
