Preservation is green. It retains the carbon footprint of structures that are already there, requires less materials, less expense of energy to construct – because it is already constructed. It is true that some older buildings (more likely those built 1940-2000) USE more energy than new “green” buildings, but the greenest new building will still take 30-40 years to pay off its carbon debt.
Two years ago, National Trust President Dick Moe made a speech at the National Building Museum about preservation and sustainability. It was epochal. He had the statistics that proved that “the greenest building is the one already built” but he wasn’t just preaching to the choir. He was making it known that there was a vibrant, multifaceted preservation movement, and that this movement was staking its claim to sustainability and moving even further in that direction.

“Confronting energy reduction with technology in lieu of conservation is short-sighted-
-the problem is conservation is not very sexy and difficult to package and sell. ”

Neal is a longtime friend and colleague and one of several experts who have seen the limitations of LEED (Leadership in Energy and Environmental Design), which was introduced this century by the U.S. Green Building Council and has made new buildings more energy efficient. The problem is that LEED at the beginning virtually ignored old buildings, despite the fact that an old building’s carbon footprint is always less than a new one. Much of the “Green Building” industry was driven by marketing efforts to push new products. Continue Reading
