Energy Efficiency (H1)
Want to be 'All Over H1' Clause H1 of the New Zealand Building Code, which regulates the energy efficiency of buildings, is undergoing its biggest changes in more than a decade. The first phase of implementation began in 2022, with a further set of requirements beginning from 1st May 2023.
The update to Clause H1 aims to help make new buildings warmer, drier and healthier and therefore reduce the energy and environmental impact needed to heat them. The changes are the biggest energy efficiency updates to the acceptable solutions and verification methods in more than a decade.
The H1 Clause of the Building Code regulates the energy efficiency of the built environment – covering wall, floor and ceiling insulation, as well as the thermal performance of windows and doors. There are major increases in thermal performance requirements across the building envelope, indicated through higher construction R-values for different building elements.
Climate Zones
Previously New Zealand was divided into 3 climate zones - Zones 1 and 2 for most of the North Island and zone 3 for the South Island. Now, there are 6 climate zones across New Zealand, with the insulation requirements tied to these zones
Who is effected ?
The new H1 regulations only affects new construction and existing properties undergoing changes to the external thermal envelope, which will require building consent.
Two Sets Of Requirements
Minimum Insulation requirements differ across three types of buildings; Housing, Small Buildings-under 300m2 and Large Buildings- over 300m2
