New Rating System "Envisions" Sustainable Infrastructure
By Paula Melton
The Institute for Sustainable Infrastructure (ISI) has launched Envision, a framework for.
The system takes what ISI calls a holistic view, touching on quality of life, resource allocation, impacts on ecosystems and climate, and issues of risk and leadership. Project owners and design teams can use a self-assessment tool or can submit the project for third-party verification, which includes evaluation of the project during three phases: pre-construction, construction, and operations and maintenance.
Future versions of the rating system, which was developed by ISI in partnership with Harvard University’s Zofnass Program for Sustainable Infrastructure, will also incorporate additional tools for complex or multi-stage projects. More information is available at
