"The past year's marvels of architecture include innovative green office buildings, Apple's showcase store, and the world's longest over-sea bridge.....many of our favorite buildings of 2006 reflect a trend that has been gaining strength: sustainable design....Today green has become glamorous, and even economical. The cycle of innovation for sustainable building technologies is now staggeringly short, given how long it takes to complete a building. We are close to the tipping point at which green design becomes the default option for smart building."
