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:
I’m finding that many people not only have lowered their standards with regard to the user interface, but more and more often when I bring up the subject, they seem to consider it a somewhat secondary aspect, something that’s only good for ‘geek talk’. The same kind of amused reaction laymen have to wine or coffee connoisseurs when they describe flavours and characteristics using specific lingo. Something that makes sense only to wine or coffee geeks but has little to no meaning or impact for the regular person.
The problem is that if an increasing number of people start viewing user interface design as an afterthought, or something that isn’t fundamental to the design of a product or experience — it’s all just ‘geek talk’ — then there is a reduced incentive to care about it on the part of the maker of the product.
