[Strawbale] [Greenbuilding] Blower Door test set-up

[Shawna Henderson]

Chris,

I would suggest calling around to defunct EnerGuide for Houses  
evaluators. There's probably a few units out there that could be  
bought for a reasonable price.

The portability of these units is always a challenge, and I would  
look for one that has an adjustable lightweight metal frame and a  
door 'skin', sets up kinda like a tent wall. The older models, which  
were made of sliding panels of plywood are killer on the back.

If you could find a set of magnahelic gauges, you could possibly make  
a frame system, but sheesh, to make it airtight is a challenge.

Also, if you are intending to use this for any validation work (ie,  
for EnerGuide for Houses type programs), they are going to want to  
see a recognized, standard blower door kit. Indeed, if you're using  
it for any research programs, they are all going to want to see a  
standard apparatus.

The most common on is from the Minneapolis Blower Door Company. They  
run $3 to 5k US new.

Using them is relatively easy, once you've got the door set up. If  
you like I can run you through the process. I've done it about a  
bazillion times...
