Retrofitting Old Structures = Green Building

If there's a better compendium of information online about the state of the built environment (i.e. where we all live and breathe) than The Atlantic's Cities blog, we don't know it. Today they report on the results of a study conducted by the Preservation Green Lab- a wing of the National Trust For Historic Preservation- on whether new green buildings are inherently more environmentally-friendly than retrofitting the old ones torn down to make way. After crunching a data set gathered in a variety of cities (including Atlanta), they've concluded that retrofitting the old buildings to be more energy efficient is the wiser path. If this admittedly glib summary of the mildly technical but still quite approachable piece is not satisfactory, click the handy link! [The Atlantic Cities blog]
