Is it true (I know that there are people around here who would know)
that straw bale construction instantly warrants an F or G rating,
because although it's actually quite well insulated it's not an option
for the type of construction and so falls through to the worst
possible assumption.

Surely it's not hard for the software to allow user defineable wall types -
with specified U-values?

Certainly the little EPC software I've seen in
action not only assumed that the user was probably an innumerate
idiot,

Oh - yes that explains it - can't expect much from a "new career" failed

but refused to work in any way smarter than a multi-choice
idiotic way, even when they did have an understanding of U, R & K.

Our own place is 120 years old, so obviously scores (and deserves) a
Z. I just wonder why we had to pay so much money for someone to have a
laptop tell us this self-evident fact. Was it so that we could also
have the recomendation to install low-energy lights and a windmill,
with no advice at all as to the relative capital costs or likely
benefits of each.

Because, once the powers that be have attached their sticky fingers onto a
random mantra, they don't (or are incapable) of considering the "bigger
picture" or "thinking outside the box", which is odd as that's all some of
them ever seem to prattle on about. Most of our politicians actually love
their little box and would have a heart attack if you removed them from it
and threw them into reality.
