Cob: How standards have changed.

Thanks for the link.  Looks like the wright house might be generously rated 
at 3 for the walls, 2 for the big plate-glass windows (ones in the living 
room at least might face south, not the ones in the master bedroom), a 
little under one for the small, some openable, some not, windows on the 
street (probably close onto north) side.
