Chris Stafford here,

John, at first I thought why would they be appealing to the State of WA
(Washington)? Then of course, where is there a more soggy damp place
that you can find straw bale houses, if it isn't in Western Washington
(and Oregon). David Riley's group at the University of Washington just
concluded a year of moisture testing on a small heated straw bale shed
with stucco exterior walls and gypsum plaster interior walls. It is my
understanding there was no moisture barrier under the stucco and no
vapor barrier under the plaster.

Before the shed's walls were rendered with stuccoed and plastered the
moisture counts in the bales was about 6%, after rendering the MC was
between 13% and 14%, at 55-57 degees F. The MC has decreased over this
last year.

Typically in Seattle, where the test shed resides, the average rainfall
is between 60 and 70 inches a year and this past year was exceptionally
wet. I saw David yesterday and know the report has not been written yet,
but David may be able to offer more information than I just gave. I'm
forwarding to David your email request for help.

Also don't forget to contact Joanna Karl, who you may have met at the
Int'l S B Conference in California. She has been doing moisture testing
in Portland Oregon.

Good luck, Chris
