From the CNN report: Green buildings won't save the planet.
The United States has the third largest ecological footprint per capita, behind only the United Arab Emirates and Saudi Arabia. We face an extraordinary challenge in overcoming our environmental deficit.
Here's an outstanding video and report via TED in a special report from CNN about how the entire process has to change, and how the focus must move off of buildings as static objects. The Dee and Charles Wyly Theatre in Dallas is shown as an example of how the process ends up in an unexpected place after exploring all dimensions of the problem, especially the existing footprint of the old building. It ends up being kind of a hypercube floating in space, a tesseract, that unfolds internally to meet the various demands of the space.
