On Wednesday, we discussed the LEED 25 percent rule: the LEED rating system was only intended to apply to the top 25 percent of buildings.
It is important to remember this premise when considering what is happening in the green building industry today. Many cities are mandating LEED certification for public and private buildings. For example, in Washington D.C., all new construction of private buildings greater than 50,000 square feet will have to be LEED certified after January 1, 2012.
As cities, states and federal agencies are mandating LEED certification, you simultaneously have the USGBC "raising the bar" for green buildings by bi-annually updating the LEED rating system to include even more stringent requirements for certification. The USGBC’s goal is not for every building in the country to be LEED certified. Instead, the USGBC wants "to bring in even greener and greener buildings."
You see the problem there. I know you do. But I will say it anyways.
Mandates require 100 percent compliance.
The USGBC is designing a system that only the leading 25 percent of buildings can comply with, at least in terms of certification.
Those two numbers do not add up.
