Envision™ is a sustainability rating system for the nation's infrastructure. It is designed to evaluate, grade and give recognition to infrastructure projects that make progress and contributions to a more sustainable future. Its purpose is to foster a necessary and dramatic improvement in the performance and resiliency of our physical infrastructure across the full dimensions of sustainability: economic, social and environmental. It is a comprehensive and workable rating system that will help project owners, designers and constructors make better management and investment decisions. Envision™ will help conserve and restore natural resources and ecological systems as well as strengthen the capacity and social fabric of our communities.
