Solar Form: Self-Shading

Solar architecture takes many forms.  A common form for solar houses, especially prevalent in the 1970s and 80s, included a south-facing sloped glass wall, to collect solar heat.  I trace the history of this type in The Solar House.  In the book I also discuss some ideas about solar aesthetics from that period.

Here's more evidence (not in the book) that solar architecture matured in the 1970s.  Where the opposite environmental need predominated---cooling rather than heating---the inverse formal strategy took hold.  I've collected some examples, where the architectural form is clearly meant to provide self-shading so heat gain would be minimized. 

Note that the self-shading form may be oriented to the south or to the west, depending on the site conditions and the needs of the building.

In a 1963 talk called "Solar Effects on Architecture," Vincent Kling said:
"it is obvious that the esthetics of any building design come as much from a mature, realistic approach to the sun effect as from almost any other single force affecting design concepts. As the architect solves the problem of sun effect, he is putting his stamp and flavor on the architecture."
