H1 Energy Efficiency Requirements

JOINERY SUPPLIES THROUGH GREENZ: EXCEEDING THE H1 BUILDING CODE REQUIREMENTS
The Ministry of Business, Innovation and Employment (MBIE) for New Zealand, Aotearoa, has announced an imminent update to the Building Code compliance regulations set to be implemented in November 2023. One of the documents impacted by this revision is the H1/VM1 Acceptable Solutions and Verification Methods For New Zealand Building Code Clause H1 Energy Efficiency. This is a pivotal document that delineates the verification process for the building thermal envelope across various constructions.

The upcoming H1/VM1 modifications represent a transition period in the construction sector. GREENZ is here to turn this transitional phase into an opportunity for all our clients. By prioritising energy efficiency, quality, and cost-effectiveness, we ensure our partners always remain ahead of the curve. Choose Greenz for a seamless, future-proof building experience.

H1/VM1: What’s Changing?

  • Enhanced methods to bolster the energy efficiency of building envelopes.
  • Minimum insulation/R-values and new thermal resistance determination methods.
  • The modifications have been curated to minimize the need for drastic design changes, especially for windows.
  • While the fabrication of windows will evolve, installation remains unchanged.

R-values Updates

Original R-values currently register at 0.367. The new mandates modify these values to:

  • Zones 1-4: 0.460
  • Zones 5-6: 0.50

With an R-value of 0.66, GREENZ products substantially exceed the new minimum requirement of 0.460.
