  1. 1. The Envision Rating System
  2. 2. Envision™ was developed in joint collaboration between the Zofnass Program forSustainable Infrastructure at the Harvard University Graduate School of Design andthe Institute for Sustainable Infrastructure.The Institute for Sustainable Infrastructure is a not-for-profit education andresearch organization founded by the American Public Works Association, theAmerican Council of Engineering Companies and the American Society of CivilEngineers.
  3. 3. Envision™ is a tool, which itself is part of a larger system, developed to helpevaluate the sustainability of civil infrastructure.This system includes:•  A self assessment checklist•  The Envision™ Rating Tool•  A credential program for individuals•  A Project Evaluation and Verification Program•  A Recognition Program for Sustainable InfrastructurePRE-ASSESSMENT"CHECKLIST"RECOGNITION"ASSESSMENT"PHASE TOOLKITS""COMPANION TOOLS"

  10. 10. SAMPLE PROJECTANALYSISANALYZINGALTERNATIVESTO MAKE DECISIONSEach potential alternative was studied creditby credit, providing the basis for a strategicanalysis of the benefits and risks of eachoption.Envision was used to study various potentialalternatives for a proposed bridge. The currentproposal did not include public transit, whilethree alternatives; a new bridge, a refurbishedbridge, and a tunnel, all included public transit.
  11. 11. ALTERNATIVE ANALYSIS
  12. 12. These values were added upto create a spreadsheetoutlining the overall “score”for each proposal.ALTERNATIVE ANALYSIS
  13. 13. Viewed graphically, the pointshelp to illustrate the trade-offsof each project.RESULTS Bridge  Bridge  with  Rapid  Transit  Refurbishment   Tunnel  
  14. 14. THE FLEXIBILITY OFVALUEThe three alternatives scored similarly, but indifferent ways. Envision helped to identifythese tradeoffs.Recognizing the trade-offs in variousalternatives is important for identifying thebest project for a given location and context.IDENTIFYING THETRADE-OFFSWhile Envision establishes a point value foreach credit and level of achievement,communities may find they value the uniquequalities of their historic districts, habitats, orresources differently.
