Building Code changes affecting new homes
The Ministry of Business, Innovation and Employment (MBIE) has introduced 6 new climate zones (see map on right) which now means new homes can be better designed and built based on the climate they're in.
The new Building Code changes are expected to reduce the energy to heat and cool new homes by 40%. The changes for residential insulation are as follows:

These building code changes impact significantly on new builds. We have products and solutions that can help you, or we can help your architect/ designer with our H1 Calculations to help ensure you comply with the new regulations.
The insulation requirements for existing homes remain unchanged.
The desire for warmer, drier healthier homes is reflected in these changes, as the longer term energy costs savings and increased health benefits will be substantial. Higher insulation R values not only increases energy efficiency in building but also improves the health, comfort and wellbeing of the occupants. These changes are also likely to achieve cost savings to the health system because of reduced hospital admissions and GP visits.
The effective date of the new acceptable solutions and verification methods was 29th November 2021 with a transition period of one year ending 3rd of November 2022. You can read more about the Building Code changes on the MBIE site here.
