suggestions for hot attics:

1. a positive pressure solution (i.e. fan blows into attic and out a
vent,
rather than sucking air out and RADON in)

Agree with that. Attic venting shold be independent of the house unless you
are taling a whole house fan. OTOH, I'm not convinced radon is the threat
some make it out to be.


2. even better is a white roof, studies have shown that a white colored
roof
is 7 times as efficient for eliminating attic heat than any vent, fan, or
turbine system

Makes a lot of sense in hot climates, but in the winter, it is not a savings
here.
