After almost a decade of requiring LEED certification for all federal building projects, the U.S. General Services Administration (GSA) is suggesting in a new report that the Green Globes rating system aligns slightly better than LEED with federal requirements for new construction, while LEED remains the most compatible green building rating system for existing buildings.
The differences identified between the two systems are not marked, and the report acknowledges that apples-to-apples comparisons are difficult.
