[GSBN] Can bale buildings be air tight?

[ejgeorge at riseup.net]

Are you suggesting that the true rationale behind Passivhaus's .60  
ACH50 number is that Wolfgang Feist is a Jose Theodore Fan? ;)

With regard to showing where infiltration occurs, the link below is  
for Jacob Deva Rascusin's Energy Performance for Straw Bale Buildings  
paper, including thermal imaging on 7 bale buildings in the Northeast  
US.
Infrared pictures begin on page 40 and a summary of air leakage points  
(& related moisture issues) is on pages 22-23. There's also some  
suggestions for construction techniques and detailing in the  
conclusion section.
