The recently released DOE proposal for home energy ratings is getting closer to what's needed.
As I mentioned last month, the LEED system falls short of usefulness, and the best rating should be in dollars. The DOE system is in dollars, all right, but they are unfortunately using savings, not cost. Home size and "average energy cost of a home without upgrades" needs to GO AWAY. Give us a standardized yearly energy cost for this house, period. It's much simpler, and ultimately much more useful for everyone.
