Verification Method H1/VM1

Verification Method H1/VM1 is a part of the New Zealand Building Code. It provides a performance-based alternative to meeting the requirements of Clause H1, which specifies the minimum energy efficiency standards that buildings in New Zealand must meet.

Verification Method H1/VM1 allows building designers to use alternative solutions and designs to meet the performance requirements of Clause H1, provided that they can demonstrate that the proposed design will achieve equivalent or better energy efficiency outcomes.

It sets out a process for verifying compliance with the energy efficiency requirements of the Building Code via energy modelling. By providing a performance-based alternative to the prescriptive requirements of Clause H1, Verification Method H1/VM1 allows for greater flexibility and innovation in building design while ensuring that buildings meet minimum energy efficiency standards and contribute to the overall sustainability of New Zealand's built environment.
