Hemp Passive Haus 1st Blower testing

James B. the client (and also the builder) is on track to achieve passive Haus Certification. For several weeks he was taping and sealing the dwelling.

Today Gavin O Se from Greenbuild, Gorey, Co. Wexford did the preliminary door blower testing to see how the build is performing to date.


Gavin also used a thermal anemometer. The air speed is measured at the access points, allowing for comparisons and for the leaks to be prioritised by severity.

He did spot checks around all windows. Gearoid from Optiwin windows was on hand if adjustments were needed.
The preliminary pressure result in under 0.8h-1 at 50Pa. And this is without outside plaster work!

The 0.6h-1 at 50Pa for a Passive Haus should be achievable.

Well done James (with hat).
