Thermal Delight in Architecture
The Cinderella of architecture
Two thermal archetypes
Sonorisms III
Anasazi dwellings
Migration within buildings
Fascination with control
The notion of a thermal optimum persists
A simple pleasure that comes from just using it
Their opposites close at hand
Substitutes for the thermal experience
The totality of its sensory stimulation
We need an object for our affections

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.
Thermal aediculae
The inglenook, the gazebo, and the porch swing also have strong definitions of their spaces. They are each a bit like a little house set off for a special thermal purpose. They might be termed "thermal aediculae". Although the term aedicula is most often used in conjunction with a sacred or ceremonial little house, it can also be used to describe any diminutive structure used to mark a place as special.
Summerson contends that there is a basic human "fascination of the minitature shelter." Perhaps this is because the aedicula intensifies ones experience of the place by working someone like a caricature. By reducing some things in scale, it exaggerates the importance of other things, most especially the size of a person in relation to the space.
At a uniformly comfortable termperature
In America our tendency has been to get away from thermal conditions as a determinant of behavior. Instead, we have used our technology to keep entire living and working complexes at a uniformly comfortable temperature. As a result, our spatial habits have become diffused, and activities that were once localized by thermal conditions have spread out over a whole house or building. We forget, unless a system breaks down, that such wide-ranging use of space is extremely dependent upon the available heating and cooling equipment.
For their own concealed passion
Sharing the experience of a pleasant thermal setting may add an extra bonus to courtship. The gentle and cooling breeze of the southern porch swing provided a happy excuse for a couple to sit quietly together. A more technological version might be seen in the type of car that the teenagers of the 1950s considered ideal for a hot date—the convertible. Slightly more erotic, perhaps, were the atrium and green houses that were favorite settings for romance in Victorian England. The lovers could get lost among the leaves of the exotic tropical plants and possibly mistake the hot, humid atmosphere for their own concealed passion.
The kairo
The Japanese have notoriously unheatable houses. They have traditionally preferred to design their houses to be cool and airy in summer and then to get by in the winter with localized ways to heat the body. Smallest of all means is the kairo, a little case carried around in pockets or between layers of clothes that contains a warm charcoal ember.
The ritualized use of a place
The association of comfort with people and place are reinforced by the ritualized use of a place. Using a place at a set time and in a specific manner creates a constancy as dependable as the place itself. It establishes, in time and behavior, a definition of place as strong as any architectural spatial definition, such as an aedicula, might be. Ritualized use can do more than reinforce the affection for a place. Through ritual, a place becomes an essential element in the customs of a people.
Functionalism can be a kind of religion
We are not now inclined to regard modern heating and cooling systems as representative of a spiritual realm. The physical principles involved in their operation are thoroughly understood; there is no mystery about them. They are simply functional, designed according to straightforward engineering practice to serve their intended function as efficiently and conveniently as possible.
And yet functionalism itself can be a kind of religion.
...From the fifties and sixties we have inherited numerous heating and cooling systems created within an ethos of universal convenience. Machines to maintain our thermal comfort were conceived of as mechanical servants, providing for our every need while, like an English butler, remaining as unobtrusive as possible.
Protected, yet tuned in
Karen Terry's house in Sante Fe, designed by architect David Wright, is perhaps one of the most compelling passive designs.
Stepping down its hillside site in four tiers, it nestles low into the ground. Thick adobe sidewalls create a strong sense of shelter and its banks of windows look resolutely to the sun. The image is very much of a house attuned to sun and earth.
Rather than providing the convenience of a constant indoor temperature regulated by a thermostat, a passively solar-heated house may go through an air temperature flux as great as 20ºF per day. People learn to live with this flux.
Living in a solar house is a whole new awareness, another dimension. I have the comfort of a house with the serenity of being outdoors—protected, yet tuned in.
Blessed by the four elements
The Indian stone temple also included, in its architectural form, the means for being blessed by the four elements—earth, wind, water, fire.
- Before entering the temple gates, one removed one's shoes to touch and be blessed by the earth.
- Then upon passing through the temple gateway, one is blessed by the air with a gust of wind.
- A blessing by water is obtained by bathing in the temple tank, or at least descending its steps to touch the water.
- Finally, on entering the cool interior of the sanctuary, the worshipper is given a mark on the forehead with ashes taken from a sacred flame by an attendant priest. Even this blessing by fire has a slight cooling sensation to it.
Perhaps it is only coincidental that each of these four blessings is associated with a cooling sensation; and yet, the use of forms and materials that inevitably create coolness is quite remarkable.
Each ruler commissioned his own garden
The Mughuls of India developed a tradition where each ruler commissioned his own garden. Then, "At the owner's death the pavilion, generally placed in the center of the site, became the mausoleum, and the whole complex passed into the care of holy men."
The ancient fire spirit who lived in the hearth
The garden is as central to the concept of an Islamic home as the hearth is to the European home. It is interesting, then, that the hearth-fire in old traditions has a similar association with the life of the inhabitants of the house.
Commonly, the fire of the hearth was not allowed to go out. It was carefully covered with ashes each night at curfew so that a few selected embers would survive until morning. (In fact, the word "curfew" originated from the French word for cover-the-fire—couvre-feu.) Raglan comments that "the alarm and horror felt if the hearth-fire went out are out of all proportion to the inconvenience caused" by the need to relight it.
The housewarming ceremony
The connection between the life of the fire and the life of the inhabitant is also reflected in the custom of the housewarming ceremony. In contemporary America a housewarming party is given when a family moved into a new house. Perhaps all of the friends and their good wishes are thought to warm the house metaphorically. In traditional cultures, however, the warming is quite literal, for it involves the bringing in, or the first kindling, of the hearth fire, which then creates the proper spirit and sanctity to transform the house into a home.
Fire, the animating spirit
We can easily imagine from our own experience why fire might be used as a symbol of the life of a house and the family that lives there. The fire was certainly the most lifelike element of the house: it consumed food and left behind waste; it could grow and move seemingly by its own will; and it could exhaust itself and die. And most important it was warm, one of the most fundamental qualities that we associate with our own lives. When the fire dies, its remains become cold, just as the body becomes cold when a person dies. Drawing a parallel to the concept of the soul that animates the physical body of the person, the fire, then, is the animating spirit for the body of the house.
