[photo credit: Vincent Kessler]A three dimensional sundial house? You can find it at 10 rue du Diebach, Cosswiller near Strasbourg in the countryside of Alsace in France. Eric Wasser has created the "Heliodome", a tilted circular building aligned with the earth's polar axis that is a far cry from the old Buckminister Fuller "Bucky Domes".
The house has a glassed southern exposure to allow sunlight during the winter, but from the equatorial belt forward the house has a nearly conventional roof providing shade during the summer. As Wasser explains on his website, "The passive solar house is an architectural volume, a Heliodome, determined by the diurnal and annual trajectory of the sun."
