Colorado Solar Hogan Demonstration

College of Environmental Design, University of Colorado/Boulder, 1987-1990

This Project is a collaboration with Dr. Charles Cambridge

According to an ancient myth, when the Navaho People (Dine) came from their previous world into the present world, the Twin Gods of War went to the sun, who was not yet a Navaho god, to accuse him of being their father. The sun lived in a solar house. He told the Twins to return to the People and tell them that in the future they would all live in houses like this...and the young people would show everyone how to make them.

    The Colorado Solar Hogan Demonstration, with its three hogans. The largest on the left has a traditional hogan at its core, surrounded by another 1200 sf of solar heated space; in the middle is a traditional hogan with a passive solar porch wrapped around the south side; the traditonal stone hogan at the right, has had the south mass walls converted to Trombe walls, using a "homemade" fiberglass material for glazing.

    Nasser Jafar, a native Kuwaiti, a student with a background in big construction in offshore oil platforms, acted as the Project construction supervisor. He got the construction process on track, when it got into difficulties from time to time.

    Wooden structural members for the project were collected from a recent Boulder County forest fire, and then pealed with draw knives by this spirited (and grimy) group of students.

    Students experimented with different ways to construct the traditional cribbed-log domes.
