Update to Envision™Rating System
An updated version of Envision™, the Institute for Sustainable Infrastructure rating system, is now available.
The new version of Envision™ includes significant alterations as the result of public comments submitted since July 2011 and the merging of the ISI rating tool with a similar tool developed by the Zofnass Program for Sustainable Infrastructure at Harvard University.
Details associated with the individual credentialing process, including training schedules, fees, application procedures, and guidelines for individual infrastructure project submissions for ISI accreditation, are also available.
