Institute for Sustainable Infrastructure Information

ISI advances sustainable civil infrastructure using Envision® — through education, training and third-party project verification. The Envision Sustainability Framework and rating system is deployed by people and projects throughout North America and internationally and is applicable to every type of civil infrastructure: water, transportation, energy, waste, land/environmental, and more. OUR HISTORY: Based in Washington, DC, ISI was established in 2010 by the three largest engineering associations — the American Society of Civil Engineers (ASCE), the American Council of Engineering Companies (ACEC), and the American Public Works Association (APWA). ISI collaborated with the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design to develop Envision.
