Test a New Sustainability Certification Rating System

Institute for Sustainable Infrastructure logo

The Institute for Sustainable Infrastructure is an independent non-profit organization tasked with developing and administering a rating system that will certify North American infrastructure as sustainable. The organization was founded by the American Council of Engineering Companies, the American Public Works Association and ASCE.

Official envision logoThe ISI rating system, envision™, is founded on the “triple bottom line” concept of sustainability, which includes environmental, economic and social considerations, and it is designed to identify the benefits of sustainable practice for owners, regulators and practitioners. It represents the only comprehensive assessment system that strives to improve a project’s social and environmental performance, while also accounting for economic benefits and creating a better long-term value for the community. Not only will the system evaluate and score existing infrastructure, it will serve as a goal for new and renovating projects to achieve. Unlike other systems, envision will include an option for third-party verification, and will be applicable to a wide range of infrastructure projects, from roads and bridges to energy and water systems. Its robust, objective and transparent methods will also promote community and policy acceptance of sustainable solutions and encourage knowledge sharing, innovation and collaboration in the design, construction and maintenance of infrastructure.

The rating system needs your civil engineering expertise to increase its reliability and value. ISI is currently seeking feedback on the version 1.0 draft of envision. Your critical review will help ISI improve envision’s methodology and utility. To read the draft and comment, visit ISI’s Web site, All comments and suggestions are confidential and will be considered. Comments will be accepted through early 2012, with an official rollout shortly thereafter.
