Description

Acceptable Solution H1/AS2 provides a means of compliance with Building Code Clause H1 Energy Efficiency. 

Clause H1 provides for the efficient use of energy and sets physical conditions for energy performance.

Acceptable Solution H1/AS2 can be used for buildings other than housing with an area of occupied space greater than 300 m².

For all housing, and buildings other than housing with an occupied space less than 300 m², refer to the Acceptable Solution H1/AS1 or Verification Method H1/VM1 as a means to demonstrate compliance or use an alternative means to demonstrate compliance.

Scope

The Acceptable Solution H1/AS2 does not include the use of foil insulation.

This Acceptable Solution does not apply to buildings with curtain walling. For these, use Verification Method H1/VM2 or use an alternative means to demonstrate compliance.

For commercial buildings, the Acceptable Solution H1/AS2 does not include requirements to comply with clause H1.3.6 of the Building Code for the energy efficiency of HVAC systems. For this clause, use Verification Method H1/VM3 or use an alternative means to demonstrate compliance.

Notes/comments

This is the first edition of H1/AS2. However, prior to its release, similar requirements were previously found within H1/AS1. The main changes from the previous version of H1/AS1 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 larger buildings have been combined into Acceptable Solution H1/AS2. 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.
  • Buildings with curtain walling have been excluded from the scope of H1/AS2.
  • Citations of NZS 4218:2009 “Thermal insulation - Housing and small buildings” and NZS 4243.1:2007 “Energy Efficiency – large buildings. Building thermal envelope” have been removed from the document. The relevant content from these standards has been adopted into H1/AS1 and H1/AS2 with permission from Standards New Zealand.
  • The three-zone climate zone map previously found in NZS 4218 and NZS 4243.1 has been updated with a six-zone climate zone map in Appendix C.
  • The minimum R-values previously found in NZS 4218 and NZS 4243.1 have been replaced with new values found in Part 2. Building thermal envelope.
  • References have been revised to include only documents within the scope of H1/AS2 in Appendix A.
  • The definitions page has been revised to include all defined terms used in this document in Appendix B.
  • Requirements for establishing the orientation of a building have been added in Appendix D.
  • A new procedure for calculating the construction R-value of windows, doors, and skylights has been added in Appendix E.
  • Tables with construction R-values of selected slab-on-ground floor scenarios have been added to a new Appendix F.

H1/AS2 (First Edition) will be valid till August 2022, then will be replaced with H1/AS2 (First Edition, Amd 1).
