Come and visit our 1970’s home that we have been retrofitting to Passive House Principles to be more energy efficient. Air tightness of this home has produced some amazing results, but insulation consistency is also important! Achieving 5ACH@50Pa. Some initiatives we have undertaken include spray foam walls and floor insulation, LED lighting, and retrofitting double-glaze and triple glazed windows. A grid-connected solar system provides a renewable energy source. We monitor our energy and air quality and as our house is well sealed we have forced energy recovery ventilation.  All ducting, gas and evaporative system, has been removed resulting in a ductless, gasless and well sealed home with split system climate control.  HRV ventilation system installed with strategic ventilation implementations in the bathroom and toilet.

Our home includes;

  • 8000 above ground storage
  • 2000pa cost saving estimate
  • Efficient lighting
  • Efficient appliances
  • Energy monitoring
  • Draught proofing
  • Spray Foam floor
  • Water wise plants in garden
  • 2.6 internal and external walls rating
