Description

The Verification Method H1/VM2 provides a means of compliance with Building Code Clause H1 Energy Efficiency.

The Verification Method H1/VM2 applies to communal residential, communal non-residential (assembly care only) and commercial buildings with a floor 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 demonstrate compliance.

  • The method for determining the thermal resistance of framed walls has been revised and the wall R-value in the reference building has also been reduced.
  • The application of minimum construction R-values of heated ceilings, heated walls and heated floors has been clarified.
  • The method for determining the areas of roofs, walls and floors now requires the overall internal dimensions to be used.
  • References have been revised.
  • Definitions have been revised.
  • The verification method now refers to the Building Product Specifications for determining the thermal resistance of insulation materials, and reference to AS/NZS 4859.1 has been removed.
