Dark roofs produce hot attics. Too many corners increases surface area & heat transfer. Zero energy is NOT just adding PVs on a poorly-designed conventional house. It involves a wholistic approach.
Energy conservation is three quarters of TRUE zero enrgy design, especially "off the grid," with no power company connection at all. The fact that this builder is TRYING to learn zero energy concepts means they are on the right path, but still in the "novice" category.
