When you think about it, a window has a complicated job: it must allow the sun's light to pass though, but not the sun's heat. It must keep cool conditioned air inside, but not have condensation on the outside of the glass.
One of the more interesting and exciting aspects of the "new urbanism" movement is that the next paradigm could well be much more than the return to the close-knit community of small villages and towns.
What the New Urbanists take from Jane Jacobs is what nearly every other planner or urbanist working today takes from Jacobs regardless in what context they work: a set of pro-urban values. Love of the city.
Today's efforts to recreate elements of the city, of whatever prescription of urbanism (e.g., "new," "landscape" or "ecological"), often turn on issues once considered in design competitions long forgotten.
