Very helpful. I will study it all further.<BR>

They talk about this issue with straw and other types of wall systems and go into considerable detail. I would get in touch with them and see what they have to say. <BR>

Hi Martin, <BR>
Without going back to the details, I could be mistaken, but it seems that a study by Ken Haggard a while back addressed this or similar properties. I found reference in a GSBN email from '07- see below. Is this the same metric?<BR>

There is that chapter from Ken Haggard and Polly Cooper on Natural<BR>
Conditioning in the book Alternative Construction where they look at<BR>
this. I was looking at it just recently for some curriculum development.<BR>

someone toss out some similar observations about thermal storage, that on a<BR>
diurnal cycle, plaster is activated to a depth of about 2-3 inches<BR>
(5cm -7.5cm). I have always figured that the exceptional thermal<BR>
performance of<BR>
straw bale buildings is not due solely to the high R-value. The broad<BR>
thermal mass of the plastered walls, readily available to indoor air for<BR>
heat exchange, modulates temperatures like my pink Cadillac modulates bumps<BR>
in the road.<BR>
<BR>
Does anyone know of research and measurements of short and medium thermal<BR>
storage in walls?<BR>
