heat
Winter is by far the oldest of the seasons
...and we feel warm because it is cold out-of-doors.
Retained as a quality
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.
Two thermal archetypes
The hearth, a refuge of dry warmth from a cold world, and the oasis, a preserve of coolness and moisture in a desert wilderness.
The notion of a thermal optimum persists
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.
Warmed by the afternoon sun
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.
Predicted Mean Vote
A DefinitionThe 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:
- +3 = hot
- +2 = warm
- +1 = slightly warm
- 0 = neutral
- -1 = slightly cool
- -2 = cool
- -3 = cold
A lightbulb is not an idea
With conventional placeholders, such as words, we can describe patterns for a large number of situations. On the other hand it is easy to fool yourself (and others) with words, since you can avoid to be specific. Any business meeting can confirm this.
When you draw something you are forced to be specific — and honest.
Our illustration of an “idea” from above is unconventional in the sense that it conveys specific original thoughts of what an idea is. It adds value to the words.
And that is the catch: The drawing must be unconventional to support the conventional words. We have to make sure not to use “words in disguise”. Take a common illustration for “idea” for example, which haunts flip charts all over the world: the lightbulb.
The lightbulb image works on a purely symbolic level, it only replaces the word “idea”. This image of a household item contains no original thought about what an idea is. While symbols like these work well as international replacements for words or icons to indicate a light switch for instance, they convey no nutritional value as illustrations — they are empty.
