Last week, I mentioned the renewal of the tax credits for wind energy. Another report which came across my desk recently is one from SustainableBusiness.com, in which it is reported that some (although certainly not all) of New York City’s oldest buildings are out-performing LEED-certified buildings.
The magazine compares the new 7 World Trade Center, a LEED-Gold certified project, to the 1930s-era Chrysler Building, which is more energy efficient. The 7 World Trade Center building has an Energy Star score of 74, while the Chrysler building scores 84 (in part due to extensive efficiency upgrades).
The cited reasons include thicker walls, fewer windows and less ventilation in the older buildings, as well as the fact that LEED-certified buildings look at other environmental features, such as the kinds of materials used and recycled, water systems, and proximity to public transportation.
Does this surprise you? Are you a critic of the LEED process or an advocate?
