Some cities want to move beyond LEED as a green building standard as they wonder whether LEED is sustainable enough. For example, LEED doesn't measure energy use and costs, so New York City now requires commercial property owners to report that data. The city will put together a public report with that information in hopes of encouraging owners to perform renovations. However, LEED will update its standards in 2012 and could still lead the green-building way, according to one green builder. "Ever since LEED was created, there's been someone waiting to pronounce the death of LEED as we know it," he said.
