The First-Ever Holistic Framework for Rating Sustainability of Infrastructure Projects
– In today’s environment in which infrastructure must perform, it has become increasingly challenging as demands for energy and water resources climb. The professionals who design and build these projects face a tall order in the years ahead: satisfying ever-growing demand, while at the same time responsibly addressing the potential effects caused by climate change and the increasing demand for resources, through integrating sustainable techniques in infrastructure design and construction. The works that best meet those challenges – and can serve as an example to others – can qualify for verification under Envision™
, the first rating system to gauge infrastructure sustainability.
is the product of a strategic alliance and collaboration of several organizations including the Institute for Sustainable Infrastructure (ISI)
, a nonprofit organization co-founded by the American Public Works Association, the American Society of Civil Engineers and the American Council of Engineering Companies, and the Zofnass Program for Sustainable Infrastructure at the Harvard University School of Design.
“To meet the serious challenges that we face for infrastructure, the Envision™
rating system is designed to be used as an integrated education/resource library, as well as a project assessment that recognizes the need to stretch the traditional design boundaries in which infrastructure projects are judged, not only by how they are delivered, but by how long they last, accounting for durability, flexibility and utility of the constructed works,” said ISI Executive Director William Bertera. “This new sustainable infrastructure rating system is a cutting-edge development for the world’s infrastructure design and built environment.”
The new sustainable infrastructure rating system will evaluate, grade and give recognition to infrastructure projects that provide progress and contributions for a sustainable future. Its purpose is to foster a necessary and dramatic improvement in the performance and resiliency of physical infrastructure across the full dimensions of sustainability: economic, social and environmental. “Designers, infrastructure decision-makers, and the public currently face a proliferation of sustainability rating tools, most of which focus on the performance
of a particular infrastructure element, rather than its contribution to the system
in which it resides,” Bertera said.
To focus on this, EnvisionTM
takes a new tack by establishing a holistic framework for evaluating and rating infrastructure projects against the needs and values of the community; ensuring that the true sustainability of tomorrow’s infrastructure is addressed by considering the entire life cycle of projects at a systems level. “EnvisionTM
not only asks, “Did we do the project right?” but also questions, “Did we do the right project,’” said Paul Zofnass, the founder of the Zofnass Program for Sustainable Infrastructure at the Harvard University Graduate School of Design.
In addition, EnvisionTM
raises the bar on sustainability performance by recognizing efforts that replenish and restore natural resources and ecosystems, and evaluating infrastructure throughout its full life, with ratings for design and planning, construction, operations, and decommissioning. To do this, the initial release of EnvisionTM
this month will address the design and planning phase with subsequent phase ratings to follow.
Within each phase, sustainability objectives are organized in three tiers; categories, subcategories, and credits. By meeting objectives within a credit, projectsearn points toward their rating score. The achievement of points within the credit is scaled in five levels to ensure all efforts to achieve sustainability are rewarded proportionally.
“Recognition of the challenges, issues, and complexity of achieving sustainability is a necessary step in improving infrastructure development,” said Bertera. “The purpose of EnvisionTM
is to initiate a systemic change, which improves not only project performance, but the mindsets of designers, project owners, and decision makers; to transform the way infrastructure is designed, built, and operated.”
Educational programs will be offered in conjunction with the new rating system’s release, to not only train individuals to use EnvisionTM
but to incorporate systems-level thinking into their approach to sustainability, considering the broader, often overlooked, impacts of a project.
In addition to the release of EnvisionTM,
the Institute for Sustainable Infrastructure and the Zofnass Program plan to release two companion tools this year: a pre-planning checklist for assessing project sustainability in increasing awareness of issues, and a comprehensive guidance document and score calculator that allows users to analyze and rate a project’s levels of achievement for sustainability objectives. Both tools are under development and important steps in realizing the goal for a holistic system.
