The American Institute of Architects has released a study of three of the most widely used green building rating systems (Green Globes, SBTool 07, and LEED NC 2.2) (via Environmental NewsBits).
The report finds Green Globes lacking when it comes to certifying a project, needing more stringent and specific requirements in the areas of energy reduction and operational performance. The U.S. Green Building Council’s LEED NC 2.2 system is good example of a rating system that provides a measurement of environmental achievement, according to the report. And the International Initiative for a Sustainable Built Environment’s SBTool 07 would be stronger if there were more “required” items vs. those that are simply “encouraged” and required project documentation.
The study assesses the effectiveness of the rating systems in supporting the goals of the AIA sustainability position statement with an emphasis on energy conservation improvements. The AIA has a goal of carbon neutrality in buildings by 2030.

The aim of the analysis is to show the public and the building industry the role the three most popular rating systems play in the AIA’s ultimate goal of carbon neutrality in buildings by 2030.
Last month AIA named its top ten sustainable building designs.
