Description

Verification Method H1/VM1 provides a means of compliance with Building Code Clause H1 Energy Efficiency.

Verification Method H1/VM1 applies to:

  • a) housing; and
  • b) other buildings with a floor area of occupied space no greater than 300 m², that are communal residential, communal non-residential (assembly care only) and commercial buildings.

For buildings that do not meet these characteristics, refer to the Acceptable Solution H1/AS2 or Verification Method H1/VM2 as a means to demonstrate compliance or use an alternative means to demonstrate compliance.

Scope

The Verification Method H1/VM1 does not include:

  • the use of foil insulation,
  • requirements to comply with Building Code clauses H.1.3.1(b), H1.3.4, H1.3.5 or H1.3.6. For these clauses, use an alternative means to demonstrate compliance.

Notes/comments

This Verification Method is the fifth edition of H1/VM1. The main changes from the previous version are:

  • The scope of H1/VM1 has been reduced to cover only housing and buildings less than 300 m². Requirements
    applicable for large buildings have been combined into the new Verification Method H1/VM2. To reflect the new scope of the documents and the new document layout, a new introduction and scope has been provided in Part 1. General.
  • Citation of NZS 4218: 2009 has been removed from the document. The relevant content from this standard has been adopted into H1/AS1 with permission from Standards New Zealand.
  • The three-zone climate zone map previously found in NZS 4218 has been updated with a six-zone climate zone map in Appendix C.
  • The minimum R-values previously found in NZS 4218 are replaced with new values and new text in Part 2. Building thermal envelope.
  • References have been revised to include only documents within the scope of H1/AS1 and have been amended to include the most recent versions of NZS 4246 and ALF in Appendix A.
  • Additional references have been added to include BS EN 673, ISO 10077-1 and -2, ISO 10211, ISO 10456, ISO 12631, ISO 13370, and ISO 13789 in Appendix A.
  • The definitions page has been revised to include all defined terms used in this document in Appendix B.
  • The computer modelling method for determining the building energy use has been provided in Appendix D.
  • A new procedure for calculating the construction R-value of slab-on-ground floors has been added in Appendix F.

H1/VM1 (Fifth Edition) will be valid till August 2022, then will be replaced with H1/VM1 (Fifth Edition, Amd 1).
