Blower Door Test Round 2

Posted on: October 29th, 2015 by Barley Store

Efficiency Matrix were integral to testing the 5×4 Project for air tightness.

We were aiming to hit standards developed in Europe by Passive house. One of these tests involved a Blower Door Test – stay tuned for the results!

Geothermal is hot to trot

The Geothermal system has finally been completely installed!
What began long ago with drilling holes into an empty worksite, has finally had the finishing connections put in and is blowing both hot and cold air throughout the house via the modest ducting and vents!

Rayson RTK is working with our 5×4 Team to construct the important ducting system.
These ducting pipes will allow the building to circulate air, working to keep the air fresh whilst still maintaining a stable temperature in every room.

This particular product is called RAYFLO, and is easily customizable to suit our unique design.

It’s no use trying to create an airtight home if you don’t know how airtight it actually is!
To help us find out how we had gone as far as making our building airtight, John from Efficiency Matrix came round to conduct a Blower Door Test.

Part of the test is wrapping or covering the obvious places where the air would be leaking – so all the windows and doors. (more…)

The process of air-tightening the building has begun!
On top of the external layer of Spaceloft insulation sits the Pro Clima, the exterior airtight layer as advised by Passive House Australia.
This was boarded roughly in place, and then taped at all the edges and joins to create an airtight wrap around the whole building.

Not surprisingly, the windows proved to be the tricky parts, although it was very important that we had a completely airtight building so as to utilise both the geothermal heat as well as the heat recovery system from Passive House. (more…)
