Looked through the site and enjoyed the write up in the Lodi Enterprise Community News May 10, 2001 Alternative energy house keeps utility bills at bay Thoughtful plan saves fuel By Elizabeth Campbell http://www.sit.wisc.edu/~hsteinbe/solarhome/lodi_enterprise.html Their LINKS page mentioned Green Builder Look here to learn the principles of passive solar design. www.greenbuilder.com/sourcebook/PassiveSol.html Learned several things about building Passive Solar Guidelines http://www.greenbuilder.com/sourcebook/PassSolGuide1-2.html referencing heating efficiency percentages.
