I don't know anything about such a system, but what is not mentioned is
of fair concern. Climate is one thing, local conditions and slope of
property another. As for the system you describe, I would want the
engineer to define the requirements for ventillating your wall system -
how much air movement required, what equipment and what will that cost
to operate. With what you describe it seems almost overkill for the
walls and not much about the floor when the 100 year rains come. I
would want to think about a sump pump for a finished basement, and water
damage doesn't necessarilly come from the outside. What about a broken
pipe?

The mention of moisture migrating upward to the sill plate puzzled me;
concrete is never totally dry as I understand, so how wet could the sill
plate get unless flooded?

Exterior drainiage is a major consideration in wet basements, so review
of grade, soil and downspouts in order? Any discussion of waterproofing
outside of basement wall, or has that been done?
