Notes/comments

This is the fifth edition of the Acceptable Solution H1/AS1. The main changes from the previous version are:

  • The scope of H1/AS1 has been reduced to cover only housing, and buildings other than housing less than 300 m². Requirements applicable to buildings other than housing over 300 m² have been combined into the new Acceptable Solution H1/AS2. 
  • Buildings with curtain walling have been excluded from the scope of H1/AS1.
  • 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.
  • Requirements for artificial lighting have been removed from H1/AS1 as these now apply to buildings outside of the new scope of H1/AS1.
  • 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.
  • The definitions page has been revised to include all defined terms used in this document in Appendix B.

H1/AS1 (Fifth Edition) will be valid till August 2022, then will be replaced with H1/AS1 (Fifth Edition, Amd 1).
