The Leadership in Energy and Environmetal Design standard is becoming quite its own recognized brand name. Bill Walsh, founder of the Healthy Building Network, fielded some questions on it in his InterActivist interview this past winter.

The standard no longer just applies to buildings, though. Neighborhood development is being targeted for a LEED certification as well. Sharing many principles with New Urbanism and Smart Growth, the certification aims to reward developers for thinking green on the neighborhood level (or larger).
