Can I be sure that my Passive House will ‘work’?

Absolutely. But it is essential that your project has been properly designed in PHPP, supported by a Certified Passive House Designer or Certifier and then well-executed on-site by Certified Passive House Tradespersons. There are over 80,000 Passive Houses of all building types throughout the world, providing very high levels of comfort in various climates. The ‘Lucky Country’ of Australia is easy by comparison!
