Norbert, I think that the interesting question about the 200 cu yd of concrete
is, what is the embodied energy, and how does it compare with the annual
operating energy of the building. Is it one year's worth or fifty? That would
put it in perspective for me.

I'm not advocating huge amounts of concrete or underground bldg, but it is
clear that the concrete displaces other materials and finishes, and if the
underground constrcution is done correctly, then a huge portion of the building
skin should never need maintenance or repair.
