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:
Sentences and words do not exist by themselves, but have natural, inevitable, unavoidable interactions with their surrounding spaces, words, and other sentences. Sentences are not independent of their spatial context, and interactions can create meanings and harms. Sentences survive content-indifferent and content-hostile spacings, but surviving is not thriving. Text space should not be owned and governed by generic productions grids, which make for convenient production but inconvenient meaning. Space can and should be content-responsive, actively contributing to meaning – forever practices in poetry, maps, math, computer code, comics, theater/movie scrips, posters. Subtle visual spacing differentiates and clarifies sentences, and meaning becomes more consequential, memorable, retrievable.
