[Greenbuilding] Barra system

[Keith Winston]

The second link you provide is for the Kachadorian book. I don't 
particularly care for it, but I also noticed the seeming parallel with 
the Barra system (I don't know details of Barra to know if they're the 
same). I do have two copies I'd be happy to sell however. Oh, I mean, 
gee it's an excellent book, worth a fortune... Seriously though, it has 
some interesting things in it. However, as I've noted before, I think 
any system that has your house air flowing through an uncleanable and 
uninspectable is flawed.

Warmly, Keith
