There are still some bugs to work out, such as giving passive solar and thermal mass its proper due (trombe walls are still seen as windows and heat loss) and my own
personal pet peeve is that the
reference house
assumes 13 SEER air conditioning.
I also want to state that I have always
assumed distributing fan art is legal, even if I did use copyrighted assets as
references and even if they are trademarked (I see it everywhere in drawings, etc., so long as I don't use it for profit or any other
personal gain...?)
