Development of Envision

The core of Envision was developed by the Zofnass Program at Harvard, starting in 2008. ZPH worked together with the Institute for Sustainable Infrastructure (ISI), after ISI was founded in 2011, on the system that ZPH had already developed to create Envision. This state-of-the-art, holistic sustainability rating system and planning guide allows professionals to plan and execute sustainable infrastructure projects.

ISI was founded by the American Public Works Association (APWA), the American Society of Civil Engineers (ASCE), and the American Council of Engineering Companies ACEC). Based in Washington, DC, the nonprofit 501 (c) (3) organization has a single purpose: to develop and maintain a sustainability rating system for all types of civil infrastructure. Today, ISI counts thousands of individual practitioners, government agencies, companies, and other organizations as members. Located worldwide, these individuals and organizations are actively using Envision.

ISI provides access to Envision at no cost. For a fee, ISI offers online training to individuals in applying Envision, after which they can earn the ENV SP (Envision Sustainability Professional) credential, and offers a verification and award program for projects.

ISI, as a member of the SIAB of the ZPH, advises on the research of the ZPH. Furthermore, the ZPH and ISI continue working together, complementing each other, towards further developing Envision and disseminating Envision in North America and worldwide. They share a common leadership at multiple levels, complementing each other. The ZPH focuses on research and on expanding the frontier of knowledge on sustainability in the built environment, with its research guided by the industry and ISI’s trajectory and needs. ISI addresses the sustainability needs of public agencies and engineering companies by providing a quantifiable reference and a target for sustainability via Envision, aswell as training and rating of projects.

Envision v2 system

Envision is the product of a joint collaboration between the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design and the Institute for Sustainable Infrastructure. The Institute for Sustainable Infrastructure and the Harvard Zofnass Program at Harvard University continue their collaboration towards further developing Envision, for disseminating Envision in the USA and worldwide, and in research projects related to the sustainability of infrastructure and the sustainability of cities.

The Envision system is a set of guidelines that aid in optimizing the sustainability of an infrastructure project during the planning and preliminary design phases, as well as a means to quantify the relative sustainability of the project. Although several rating systems are widely used to analyze the sustainability of individual buildings, no rating system for assessing the sustainability of infrastructure projects has gained widespread adoption. The lack of a common rating system is especially troubling because of the significant impacts infrastructure projects and networks have on the environment.

What LEED™ has done for building-scale sustainability, Envision aims to do for infrastructure: educate citizens and increase public awareness, provide a means to quantify sustainability in infrastructure, and facilitate the adoption of sustainable design for infrastructure.
