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:
A woodworker works along the grain of the wood to prevent splinter. A butcher slices across to the muscle fiber to improve tenderness. A sailor trims the sail to balance the lift and drag from the wind. When we respect the material, the material pays us back in convenience, safety, and efficiency.
Good web design requires the same understanding of and respect for the materials. And that material is the browser, along with its semantic HTML, default styles, and standard behaviors. But the wide use of design software such as Figma, Sketch, and AdobeXD has trivialized the nuances of such material into “canvases” or “artboards” of pre-defined sizes. The convenient styling and manipulation of pixels and objects have disguised the hierarchy of the DOM, the constraints of the device, and the personal preferences and browser setting from real users. Dishonest tools encourage dishonest design.
