Explanatory information

There are two Deemed-to-Satisfy pathways for complying with the energy efficiency Performance Requirements:

  • Option 1 Energy Rating — applying Specification 42 to achieve the heating and cooling loads, net equivalent energy usage, and other energy saving features such as thermal breaks, compensation for a loss of ceiling insulation, floor edge insulation and building sealing.
  • Option 2 Elemental Provisions — using Section 13 of the ABCB Housing Provisions to satisfy all the detailed provisions including building fabric, external glazing, building sealing, ceiling fans, whole-of-home energy usage and services.
