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

You can almost tell which software they were designed in
Tatiana von Preussen, cofounder of London practice vPPR Architects, says that certain software comes with constraints that encourage a particular style:
“Something I’ve noticed with new buildings is that you can almost tell which software they were designed in. For instance, if you take Revit, it’s very hard to freely create non-orthogonal, non-linear geometries, and it’s very easy to create repetitive elements, so it lends itself to a particular way of building.”
Conversational drawing
A skilled draughtsman guides design conversations by selecting and emphasizing details in a way that computer programmes cannot. Ron Slade, author of Sketching for Engineers and Architects and a structural director at WSP in London, calls it “conversational drawing”. He notes how botany field guides are always based on detailed drawings rather than photographs — as much for what they leave out as for what they show. “Extraneous material that might exist in a photograph is eliminated. It may be important to pick out and illustrate particular areas and leave other parts in sketchy or broad outline.”
The effort heuristic
Psychologists have noted that people tend to place greater artistic value on images when they can see the work that has gone into them — a tendency known as the “effort heuristic”. They are also more likely to connect emotionally with the work if they can detect the human hand, says Goldsmiths’ Chamberlain. “There’s an argument that if we see a brush stroke, we almost recreate it, and that’s part of the connection we feel with the artist — you can feel the intention.”
Perhaps to capitalize on this, some architects now show presentation drawings that look hand-drawn but are actually generated entirely by computer. “It’s totally fake,” says Brillhart. “They just take a computer image into Photoshop and put filters over it to make it look like it’s drawn by hand. It’s kind of amusing — instead of just sitting down and drawing for an hour, they spend eight hours making it look like a hand drawing.”
Tablets have caught up
But in the past couple of years, Brennan believes that tablets have caught up, with apps such as Apple’s ProCreate and Morpholio’s Trace becoming far more responsive to the user’s marks. “Tablets didn’t used to have that immediate response, from brain to eye to hand to pen to paper. A half-second delay has a huge impact on how you think — it causes you to stumble. But now that lag’s gone, it’s almost the same as drawing with pen on paper. You don’t need to engage with the airbrushes or other features — just use it in its purest form.” The stylus, too, far more convincingly apes a manual pen: “You’re able to tune it to almost replicate your favourite pen — and it doesn’t run out of ink.
Chetwood is an iPad devotee, using it to produce fantastical urban artworks as well as architecture. Far from hindering the drawing process, he believes tablets will give rise to a new era of creative drawing. “A lot of people say technology and computers are taking away the true art of drawing. That’s rubbish, it releases sketching. You can move so much quicker and change things much more quickly, and it keeps a record of what you’re doing. The control is just brilliant.” The polished glass surface is the only flaw, but textured acetates applied to the screen can make it feel more like paper.
