Some facts about some of the Certified Passive Houses Harley Builders have built in Christchurch.

  • The average house has a air leakage of 6 – 10 air changes an hour. We have achieved up to 0.35 air changes per hour.
  • With a low air change level Passive houses are able to maintain a temperature of 20 – 25 degrees Celsius.
  • Low utility bills – due to low levels of power used throughout the passive homes and the combination of solar panels and an inverter. Some have also been able to sell power back to the grid.
  • Robust and vigorous testing – for a house to become a certified Passive House the building must pass Passive house testing. (e.g. Blower door test).
  • Sealed triple glazed windows and doors – Stop air leaks, highly insulated and noise proof.
