I plan to build a passive solar, earth berm home

captaintrz | Posted in Green Building Techniques on

I’m having trouble finding out how big (diameter) and length of the earth tube to ventilate a 1500 square foot home.

The home is open design with concrete floors and walls, with exterior insulated.

    Steve provided a link to an article by Joe Lstiburek about an earth tube failure. There are plenty of other failure stories out there -- so pay attention to these caution flags.

    Here's a link to a recent GBA article on the topic: Do Earth Tubes Make Any Sense?
