Description
The newly released 6th edition of the BRANZ House insulation guide will allow designers to quickly evaluate the effect of varying construction parameters. It will be useful to demonstrate compliance under the new H1, as well as exploring options for higher performance.
Introduction of the 5th edition updates of the New Zealand Building Code clause H1 Energy efficiency H1/AS1 and H1/VM1 has expanded the tools required to work within these frameworks.
At BRANZ, one large task to support this change has been updating the BRANZ House insulation guide (HIG) to the 6th edition. All previous versions can no longer be used for compliance from 3 November 2022.
