In the New York Times on August 30th, Mireya Navarro reported in "Some Buildings Not Living Up to Green Label" that many LEED Certified buildings are not living up to hopes for performance on energy efficiency.
The council’s own research suggests that a quarter of the new buildings that have been certified do not save as much energy as their designs predicted and that most do not track energy consumption once in use. And the program has been under attack from architects, engineers and energy experts who argue that because building performance is not tracked, the certification may be falling short in reducing emissions tied to global warming.
LEED may be moving to a yearly certification to ensure performance. If you are interested in Green projects and their relation to the Community Preservation Act in Massachusetts, see my recent article in the Community Preservation Coalition's CPA Update: "Green" CPA Projects.
