No strangers, only friends we haven't met. Today we got a delightful letter from our friend Dustin. He has a great blog. In said great blog, I found this:
"The passive solar residence is a project architecture student and engineer Rich Michal led as part of the Master of Architecture program at the University of Arizona's College of Architecture, Planning, and Landscape Architecture. The home is born out of the realization that, in 2002, no good examples of passive solar design were available in the sustainable and New Urbanist Community of Civano, in southeast Tucson, Arizona—even among the community’s custom, high thermal mass homes."
Later in the article:
"A common misconception regarding thermal mass is that the outside or exterior face is the important face for thermal storage. In fact, it is the interior or inside four to six inches of the thermal mass that provides the most thermal storage. For this reason all of the interior thermal mass is left exposed or un-insulated
The exterior face of the rammed earth walls, on the other hand, were not insulated so that the aesthetic quality of the natural rammed earth walls could remain exposed. The slight energy savings associated with insulating these 2-foot-thick walls would not justify the amount of resources that would have to be expended—nor would it look as good"
