The Institute for Sustainable Infrastructure (ISI) is an independent non-profit organization tasked with developing and administering a
sustainability rating system for North American infrastructure. The organization was founded by the American Council of Engineering Companies (ACEC), the American Public Works Association (APWA)
and ASCE.
The ISI rating system 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.
The rating system will be formally launched in the summer of 2011 for public comment. A
voluntary, web-based product will be launched in early 2012. Unlike other systems, the ISI system 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.
