Performance
A Passivhaus works because a few fundamentals work together, and because we measure the result instead of assuming it. Here is what makes the difference.
A sealed envelope stops draughts and uncontrolled heat loss. We blower-door test every home with our own equipment to prove it.
A consistent thermal blanket around the whole home, with no gaps.
Detailing that stops heat escaping through the structure itself.
Thermally broken and airtight, so the weakest part of most houses becomes one of the strongest.
Fresh, filtered air around the clock, with the warmth pulled back out of the air on its way out.
We measure the finished home to check it performs the way the model said it would.
