Old Is The New Green
WHEN WE NEED to reduce our energy use, we can not afford to throw away our old buildings and cities. The materials that went into their construction are limited resources that contain enormous embodied energy, tearing them down uses significant amounts of energy while creating greenhouse gases, and "green buildings" today often rely on technological fixes that work less well than old solutions like thermal mass. Plus, of course, there is the argument about buildings that are loved are the most green, because they are the ones that will be preserved in the future. Very few people love glass towers.
John, here's another item supporting this position:
The chart shows that an historic building outperforms the average LEED building, if the LEED building is unlovable and must be torn down and replaced every 40 years. Some don't last nearly that long... think of a "Green Wal-Mart" that might last only 10 years.
