We are about to break ground on a 2400 square foot subterranean Passive Annual Heat Storage house. Davis Caves will do the construction. Your advice in the past was helpful. We'll let you know how things go.
Thanks for joining www.AGreenerIndiana.com. We have nearly 1500 businesses, groups and individuals who are sharing knowledge and ideas to make Indiana a little bit greener!
I think you will find some good resources who may be able to share some of their experiences. Join and post to the Greener Construction techniques group. If you plan on documenting your home elsewhere like a blog or something, I can RSS feed it right into the group.
A lot of people are interested in doing these kinds of things....ron owns a passive annual heat storage home.
