Thermal information is not differentiated in our memory; rather it is retained as a quality, or underlying tone, associated with the whole experience of the place. It contributes to our sense of the particular personality, or spirit, that we identify with that place. In remembering the spirit of a place, we can anticipate that if we return, we will have the same sense of comfort or relaxation as before.
There is an underlying assumption that the best thermal environment never needs to be noticed, and that once an objectively "comfortable" thermal environment has been provided, all of our thermal needs will have been met. The use of all of our extremely sophisticated environmental control systems is directed to this one end—to produce standard comfort zone conditions.
Textbooks on water-system engineering state that supply mains are generally installed on the north side of the street in the Northern Hemisphere and on the south side in the Southern Hemisphere, so that the sun will warm them. In both hemispheres they are supposed to be on the east side of north-south streets, on the premise that the afternoon sun is warmer than the morning sun.
The predicted mean vote (PMV) was developed by Povl Ole Fanger at Kansas State University and the Technical University of Denmark as an empirical fit to the human sensation of thermal comfort. It was later adopted as an ISO standard. It predicts the average vote of a large group of people on the a seven-point thermal sensation scale where:
In the terrific documentary about his work, The Secret Life of Lance Letscher, the collage artist points out that he doesn’t want his file boxes of source material organized too much, that he specifically avoids organizing them, so that he can find unexpected things when he starts searching. “He depends upon that chaos of stuff, of things lying around.”

There are several paragraphs in Murch’s book about the importance of fighting against the touted “features” of digital tools, such as speed. “The real issue with speed,” he says, “Is not just how fast can you go, but where are you going so fast? It doesn’t help to arrive quickly if you wind up in the wrong place.”

If I was simply able to execute a full-text search on my notebooks, and pull up exactly what I was looking for, that’s all I’d find: exactly what I was looking for. And the real art is in finding what I didn’t know I was looking for.
