Description

Acceptable Solution H1/AS1 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.

This document applies to:

  • a) housing; and
  • b) other buildings with a floor area of occupied space no greater than 300 m².

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

This Acceptable Solution 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/VM1 or use an alternative means to demonstrate compliance.

Notes/comments

The main changes from the unamended version of the fifth edition of H1/AS1 are:

  • Alternate thermal resistance requirements have been added to the Schedule method and Calculation method. These are only permitted to be used for housing, where building consent applications are submitted before 1 May 2023. For roofs, walls and floors these alternate construction R-values are equivalent to the requirements of the previous fourth edition of H1/AS1.
  • An additional option for determining the construction R-value of concrete slab-on-ground floors has been added to Appendix F, which is only permitted to be used for housing, where building consent applications are submitted before 1 May 2023. This additional option is consistent with the previous fourth edition of H1/AS1.
  • Throughout the document some obvious errors in the text, formatting and cross-references have been corrected, and minor text clarifications with minor to no impact have been made.
