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:
No kind of shape, no kind of design or kind of picture or other work of art can be beautiful. No kind of color is beautiful. Beauty comes always from the singularity of things. Two things which happen to be closely similar in size, color, insurance value, smell, weight, or shape, may both seem equally beautiful. It is not therefore to be deduced that, say, a smell of turpentine is a necessary prerequisite of beauty; and nor is the fact that the two things' shapes are measurably within a millimeter of each other. They might still be as different as chalk and cheese: they might differ hugely in surface quality so that one lived and the other was dead. One judges a man by what he is, by his individuality, his idiosyncrasy; not by his measurable properties or measurable behavior or by the shape of his nose or the description in his passport. So with a work of art.
