I have been thinking  a lot lately about vernacular architecture and indigenous responses to local climate.  By that I mean how a building and design practice, over time, has found architectural solutions to solve some of the problems posed by heat and cold, sunlight and shadow, aridity and humidity.  Reading through some older posts on my delving into the possibility of trying to define a Colorado vernacular, it strikes me that very few of those examples I identified tackled the issues of heat and solar gain.  That might sound like a recent concern, more one of energy use and sustainability, but a few quick glances at traditional southern architecture reveals design/technological solutions that we have largely forgotten in the age of air-conditioning.
