General Services Administration Says LEED System Is the Most Credible
WASHINGTON - The General Services Administration (GSA), which operates as the federal government's landlord, issued a report finding the U.S. Green Building Council's (USGBC's) Leadership in Energy and Environmental Design (LEED) system to be the most credible among five different systems evaluated.
The GSA report was conducted under a contract with the U.S. Energy Department's Pacific Northwest National Laboratory (PNNL). In a late summer report submitted by the laboratory to GSA, "Sustainable Building Rating System Summary," PNNL researchers compared the following five methods for rating whether a building design and construction is green: Building Research Establishment's Environmental Assessment Method (BREEAM); Comprehensive Assessment System for Building Environmental Efficiency (CASBEE); GBTool; Green Globes US; and LEED.
