Comfort, health, quality and savings

Energy-efficient homes are more than just better for the environment. By including energy efficiency features in your home, you improve the quality of the home and ensure it’s more comfortable to live in.


More comfortable than a standard build

  • More consistent internal temperature; not too hot and not too cold.
  • Not draughty.
  • Quiet.
  • Natural light.

Contributing features

  • Windows: all windows are double glazed allowing for the use of larger windows that let in more light, while helping to keep the internal temperature consistent and reduce noise.
  • Insulation: extra care was taken when insulation was installed to ensure high coverage through the walls and ceiling. Coverage was also validated through an as-built verification assessment.
  • Zoning: a well zoned home and zoned heating and cooling allows you to set comfortable temperatures depending on where you are in the home.
  • Air tightness: this home has a low air permeability rate, meaning it is draught free. This feature has been validated through as built verification checks.

Promoting improved health and well-being

  • Reduced likelihood of mould and mildew.
