SITES v2 Rating System and Reference Guide. This will be the definitive resource for project teams to use to thoroughly understand and navigate the Sustainable Sites Initiative (SITES) program's revised rating system. Embedded within SITES v2, the rating system includes improved credits based on the experience from the SITES two-year pilot program, additional research and science, and input from technical advisors and staff. SITES v2 will also include additional information on how to achieve sustainability goals outlined in the credits. It will feature credit examples, worksheets, documentation criteria, calculation guidelines, and an improved user experience. Slated for release in 2014, SITES v2 will replace the Guidelines and Performance Benchmarks 2009.

The release of the new SITES v2 Rating System and Reference Guide will be completed in 2014. Those familiar with the previous SITES Rating System, the Guidelines and Performance Benchmarks 2009, may be wondering what some of the major differences are between the two systems. These graphics illustrate the major changes to the system, such as relocated, combined, and new credits and prerequisites.
