Understanding Envision: A framework for resilient and sustainable infrastructure

Sustainable planning and design require holistic consideration of economic, environmental, and social factors. While this integrated approach seems straightforward in concept, actually implementing sustainable practices in infrastructure projects can be challenging. Project teams often struggle with quantifying sustainability efforts, determining priorities, and creating consistent evaluation frameworks.

Enter a sustainability rating system for infrastructure

Envision^® is a sustainability rating system specifically designed for infrastructure projects, developed by the Institute for Sustainable Infrastructure (ISI) in partnership with Harvard University’s Zofnass Program for Sustainable Infrastructure. Envision^® provides a structured approach to incorporate sustainability throughout a facility’s lifecycle—from planning and design through construction, operation, and maintenance. Think of it as the infrastructure equivalent of LEED certification for buildings.

How the Envision^® works

Projects are evaluated across five key categories:

• Quality of Life. Community wellbeing and engagement.
  
• Leadership. Commitment to sustainability principles.
  
• Resource Allocation. Material, energy, and water efficiency.
  
• Natural World. Ecosystem preservation and enhancement.
  
• Climate and Resilience. Emissions reduction and adaptation capabilities.

Understanding the Envision^® rating system

The rating system uses a point-based approach where projects earn credits in each category through documented sustainable practices. Each credit has specific achievement levels (Improved, Enhanced, Superior, Conserving, and Restorative) that determine the points awarded.

The total points accumulated across all categories determine the final certification level. Based on performance, projects can achieve four certification levels: Verified, Silver, Gold, or Platinum.

Navigating the Envision^® process

Envision certification follows a two-step process:

1. Initial Assessment. Project teams evaluate performance across all 64 credits, identifying sustainability opportunities early when they can be most effectively incorporated into design.
   
2. Verification Pursuit. For projects with promising scores, teams submit documentation to ISI for independent third-party review to confirm achievement levels.

Certified Envision^® Sustainability Professionals (ENV SPs) guide the assessment process, helping facilities work toward the highest standards while balancing economic, social, and environmental considerations.

Even without pursuing full verification, the initial assessment alone provides valuable insights that can improve project outcomes and sustainability performance.

To date, 396 Envision^® projects with a cumulative value of more than $283 billion have been registered, are under review, or have been completed. For projects to qualify for an Envision^® award, at least one member of the project team must have an ENV SP credential.
