Review: Low-Cost, Energy-Efficient Shelter for the Owner and Builder

old school book on ways to save energy, and live a life that uses less energy. it's a bit dated, so... i can think of a few things off the top of my head that should probably be updated.... however, for a $2 used book, it was worth it. ÍèÒ¹¤ÇÒÁ¤Ô´àË繩ºÑºàµçÁ
