THE ENVISION™ RATING SYSTEM
Envision™ was developed in joint collaboration between the Zofnass Program for
Sustainable Infrastructure at the Harvard University Graduate School of Design and
the Institute for Sustainable Infrastructure.




The Institute for Sustainable Infrastructure is a not-for-profit education and
research organization founded by the American Public Works Association, the
American Council of Engineering Companies and the American Society of Civil
Engineers.
THE IMPORTANCE OF    Planet Earth is a perilous place for humans.
INFRASTRUCTURE       Infrastructure provides:
                     • Physical Security
                     • The basis for public health
                     • Economic and commercial potential

THE REALITIES OF     • Population Growth
THE WORLD IN WHICH   • Diminished Resources
WE LIVE              • Climate Change
                     • Adaptation



A NEW FACT OF LIFE   It is no longer enough that infrastructure
                     work, that it be constructed on time and within
                     budget, or even that it last. It now must be
                     sustainable.
WHAT DO WE MEAN
BY “SUSTAINABLE”?
WHAT IS ENVISION™?

Envision™ is a tool, which itself is part of a larger system, developed to
help evaluate 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 Infrastructure

WHAT MAKES          • It applies to civil infrastructure
ENVISION™ UNIQUE?
                    • It includes design, planning, construction
                      and maintenance elements

                    • It is applicable at any point in an
                      infrastructure project's life cycle

                    • It speaks to the triple bottom line:
                      social, economic and environmental goals

                    • It is designed to keep pace with a
                      changing concept of sustainability

          IMPROVED   Performance that is at or above conventional



          ENHANCED   Indications that superior performance is within
                     reach.


          SUPERIOR   Sustainable performance that is noteworthy.


        CONSERVING   Performance that has achieved essentially
                     zero impact.

       RESTORATIVE   Performance that restores natural or social
                     systems.
