“Controlled environments” are another of modernism’s great obsessions. Extravagant amounts of energy are spent to keep buildings—as well as skyway systems, shopping malls, and domed stadia—at a constant temperature year-round via entirely mechanical means. The folly is not simply a touchy-feely isolation from the authenticities of nature, which can admittedly be cruel, but a larger disciplinary presumption that seeks to extend the centralized authority (central air, central government) of power ever more comprehensively. It is possible that this particular hubris may have pushed Gaia to the tipping point.
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.
There are several ways to start the design process, depending on your nature and needs. You can start out by defining your goals, as precisely as possible, and then look at the site with these goals in mind. Or you can take the site with all its characteristics (both good and bad), and let goals suggest themselves. Of the two questions—"What can I make this land do?"—or—"What does this land have to give me?"—the first may lead to exploitation of the land without regard to long-term consequences, while the second to a sustained ecology guided by our intelligent control.
The received version of modern architecture, with its social simplification and technical sophistication, has gotten it exactly backward. Genuinely sustainable architecture must begin with the simplest technical solutions (sunshades, cross ventilation, correct solar orientation) but conduce the most complex social relations (variety before uniformity). Invention will come not simply from the fevered acts of lonely imagination but from the constant reframing of questions raised at the intersection of climate, culture, technology, politics, and taste, by the understanding that architectural meanings are produced, not inherent.
It seems clear that for reasons of both sustainability and sociability, human power as a means of locomotion in the city should be optimized. Cities designed to facilitate walking will—because of their accessible dimensions—likely be more neighborhood-focused and compact as well as more mixed in use. To be reached by walking, a destination—whether a school, office, or shop—must be close at hand. A reasonable walking time (in this culture) for basic necessities is generally considered to be about ten minutes, which translates (at an average walking speed of three to four miles per hour) into six to eight short blocks (or three to four long ones). Using this dimension as a radius, we might begin to think of a comfortable scale for a neighborhood as ten to fifteen New York City blocks.
The conscious design and maintenance of agriculturally productive systems which have the diversity, stability, and resilience of natural ecosystems. It is the harmonious integration of the landscape with people providing their food, energy, shelter and other material and non-material needs in a sustainable way.
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.
