Earth Tubes

With the help of Trevor Butler and his company Earth Tubes we will be installing buried earth tubes in Ethel Lane House similar to the ones in the picture.  Over the centuries this “technology” has been used around the world but only recently have designers and engineers begun to revisit these systems.

Our goal is to install the equivalent of 12” diameter duct into a trench around the perimeter of the building.  This trench will simply act as a method of cooling the fresh air supply in the summer or warming it up in the winter.  We will be using 100” of polyethylene Big “O” similar to the material used in perimeter drains.
