Planning On Building Energy Efficient?

Then this place would perhaps be a good way to start - http://www.builditsolar.com/Projects/SolarHomes/plansps.htm

This website from "Build it Solar" provides a thorough list of American and Canadian builders and home plans dedicated to energy-efficiency, and especially in terms of using solar power as a main source of energy. In addition, some more alternative builders are shown, e.g. adobe home builders.

The array of builders providing energy-efficient homes are ever-increasing, which is definitely a sign for a positive market change, with increasing demand leading to increased supply.
