Many homes called Passive House aren't actually certified. Real certification requires PHPP modeling, a blower-door test, and authorized sign-off. Before buying or building, ask whether your project will be PHPP-modeled and who will certify it.

How do you know if a Passive House is actually registered? There's been a big rise in talk around Passive House homes lately, which is great in theory. The problem? The term gets thrown around a bit too loosely, and a lot of people don't realize that not every house called a Passive House has actually gone through certification. There's no restriction stopping a builder from using the term, but unless the home has been properly designed, modeled in the Passive House Planning Package, or PHPP, and tested against the standard, it's not a certified Passive House. It's a bit like calling a backyard veggie patch organic because you didn't spray it this week. You might be on the right track, but it's not the same thing. So if you're considering building to that level, just ask, has the home been modeled in the PHPP? Will it be blower door tested? Who's signing off the certification? At Enduro, we've built certified Passive House homes, and we're upfront about whether that's what's being delivered or if we're just borrowing principles for a lower-spec outcome. Because if you're going to build to this standard, it's worth making sure you're actually getting it. Want to build with more clarity from day one?
