The cliff dwellings of Mesa Verde are an excellent example of passive solar design utilized by those who came before us.
I first became aware of the synergy of efficiencies within passive solar design on a hiking trip into the desert backcountry. I saw that the southwestern cliff dwellers, the Anasazi, benefited from passive solar design.
Chaco Canyon, located in northwestern New Mexico, is an impressive example of solar oriented design.
Pueblo Bonito shows that much thought and planning went into the design and building of the massive south facing complex.
