In terms of "green" home construction, where do you get the most bang
for your buck in terms of energy efficiency? Pointers to any online
resources would also be appreciated.
Thanks.

cellulose insulation. generally cheaper than fiberglass and much much
better.

Thanks Steve, I'll check it out.

Sorry, styrofoam or equivalent is a better idea, in prefabricated
panels or subassemblies, R-30 walls and R-50 roof. Try to catch This
Old House somewhere---they are doing one of these buildings, although
it is a ridiculously large monster.
My personal experience with peripheral-insulated slab construction
makes me quite fond of it, although some people like basements. Does a
nice job of air conditioning, and smoothes out rapid ups and downs of
outside temp.
Also, some kind of heat pump.

Thanks, I'll try to check that out. Here in NC, we have a "healthy
built home" certification that provides guidelines for defining their
standards, and there is a whole section on insulation that calls for
"rigid insulation", but the rest is greek to me.
"Rigid insulation installed as a thermal break at the slab edge
(R5, 6" minimum, vertically installed)."
http://www.healthybuilthomes.org/docs/HBH_Statewide_Checklist.pdf
On the one hand, I should probably not micro-manage and just trust
that the standards that are in place are good ones, but I'm just
trying to define some "must haves" for homes that may not meet the HBH
standards, and to address the variances within the standards.
For example, some certified homes have bamboo floors while others have
concrete floors with radiant floor heat. All have heat pumps and dual-
flush toilets and some solar-assisted heating.
Haven't seen any basements, but most houses in the South don't have
basements.
