"LEED-certified buildings are still about as rare as major wind farms in the U.S. So far, fewer than 300 projects have been certified, and about 2,200 have been registered, according to USGBC officials. Registration involves a fairly simple project description and a summary of the LEED credits the developer expects to earn, but actual certification requires thorough documentation, review, and commissioning, a process that can take many months and, some green-building practitioners argue, considerably drive up costs."
"Even as debate roils about LEED's effectiveness and user-friendliness, the system is spreading rapidly. Federal departments and agencies and state and local governments are adopting LEED as a guideline or requirement for their own projects, and tax breaks and other LEED incentives are cropping up around the U.S. In many ways, LEED's success is raising the stakes and intensifying arguments over the program's flaws."
