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’ve noticed a recent trend on the web — or at least, on the parts of it I’ve visited. Maybe you’ve noticed it too.
Here’s what happens: you’re on a website, and one of these little prompts pops up...[to] let you know that there’s an app, and that the website you’re on...well, it’s not quite the app, is it?
...Sometimes, the website wants me to install the app — no, it needs me to install the app. It’s like a paywall, but for apps. An appwall.
In recent years, these prompts have gotten more prominent, and occasionally impassable. And I think that trend’s interesting. Why would a company promote a native app over their perfectly usable website?
It feels like a glimpse into that company’s design priorities. And it’s possibly providing us with insight into the business value they place on the open web — a medium that’s meant to be accessible everywhere, on any screen, on any device.
And it really does feel like these glimpses are becoming more common.
