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
Manifesto for Agile Software Development
We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.
Deliver early and continuously
Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
Welcome changing requirements
Welcome changing requirements, even late in development. Agile processes harness change for the customer's competitive advantage.
Self-organizing teams
The best architectures, requirements, and designs emerge from self-organizing teams.
Technical excellence and good design
Continuous attention to technical excellence and good design enhances agility.
Agility and sustainability
Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
The amount of work not done
Simplicity—the art of maximizing the amount of work not done—is essential.
The primary measure of progress
Working software is the primary measure of progress.
Build projects around motivated individuals
Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
Deliver working software frequently
Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
Business people and developers
Business people and developers must work together daily throughout the project.
Face-to-face conversations
The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
Reflect, tune, adjust
At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
