An interesting article in the New York Times this morning focuses on how some buildings that have earned LEED certification aren't living up to their green promises. The problem, apparently, is a disconnect between design and performance...
LEED certifies the construction of a building and not the performance (which is where things were going wrong), so starting this year they will also be requiring newly constructed buildings to hand over their first five years of water and energy bills.
From the article:
But in its own study last year of 121 new buildings certified through 2006, the Green Building Council found that more than half — 53 percent — did not qualify for the Energy Star label and 15 percent scored below 30 in that program, meaning they used more energy per square foot than at least 70 percent of comparable buildings in the existing national stock.
Read the whole article here. It's fascinating.
