Earth Bermed Homes with Passive Annual Heat Storage

	This earth berm house uses earth tubes to provide fresh air all year round that comes in warm in the winter and cool in the summer.
A manifold is used to tie the four inch pipes into a much larger pipe for entry into earth bermed homes.
	The entire ventilation system is powered by natural convection that is driven by the heat stored in the ground around earth berm houses.
