When last we posted on the Green Conscience blog, our discussion turned to sustainable, energy-efficient housing concepts collectively referred to as passive house standards. This week, I'd like to address an even more radical type of sustainable housing that takes passive standards to the next level. Known as Earthships, these structures provide the closest thing to a fully autonomous, off-the-grid existence as you can get.
Earthships are constructed to take advantage of available natural resources in the immediate vicinity, particularly in the form of solar energy. The buildings are often horseshoe-shaped and oriented to maximize natural lighting and heat-gain from the sun. Interior climate is regulated by thermal mass walls, constructed from earth-rammed tires, in keeping with the ethos of using primarily reclaimed materials.
Hi! I'm Karen Totino, owner of Green Conscience Home. I'd love to hear your thoughts on any of our posts, so comment away! One of my goals is to get the community discussing some of these eco topics, and hopefully help each other out!
