Delivering High-Performance Airports with Envision

The Runway 17L-35R Complex Pavement Rehabilitation & Electrical Upgrades Project at Denver International Airport (DEN).

At any given stage of a project, airport infrastructure professionals are tasked with making disciplined decisions across planning, design, and construction to enhance long-term performance. The Envision Framework gives decision-makers a structured way to evaluate these choices across environmental, social, and economic dimensions. Designed for use across all types of civil infrastructure, the framework aligns well with the sustainability approaches already used in the airport sector, helping project teams integrate these considerations into capital delivery without compromising operational or regulatory requirements.

A Decade of Momentum

The Envision verification program includes 69 airport projects spanning roads, stormwater systems, parking facilities, and transit connections like rail and light rail. Of these, 28 projects have achieved verification, reflecting steady momentum as airport owners and project teams increasingly use third-party review to validate outcomes and strengthen accountability.

Growth over time tells a clear story. The first airport project entered the program in 2014, with the first verification following in 2016. Activity has accelerated in recent years, culminating in 23 new registrations and 8 verifications in 2025 alone, illustrating that sustainability considerations are becoming embedded earlier and more consistently in aviation infrastructure delivery.

Among registered airport projects, 16% used version 2 (v2), while 84% are using version 3 (v3). Within v3, most teams opt for Pathway A (70%), pursuing verification after major design decisions are finalized and then confirming outcomes through a post-construction review. The remaining 30% follow Pathway B, seeking verification near or after construction completion.

Together, these trends illustrate a program that is not only expanding in volume but also deepening in rigor to give airport stakeholders clearer insight into performance and a stronger foundation for continuous improvement.

From Touchdown to Curbside: Envision Across Airport Infrastructure

The selection of projects below illustrate how the framework is being applied across both airside and landside infrastructure, highlighting tangible, measurable sustainability outcomes.

Indianapolis International Airport – Runway 5R–23L & Taxiway D Strengthening and Capacity Enhancement Project (Envision Platinum, 2023)

Serving both passenger traffic and one of the world’s largest air cargo hubs, this project marks the first FAA-approved use of a sustainable concrete mix design on an airfield, integrating carbon-capture technology directly into pavement materials.

In addition, priority was given to passenger safety and comfort through a variety of intentional and sustainability-driven enhancements. These include reducing the walking distance between bus stops, providing covered walkways for protection from adverse weather, and improving pedestrian safety with blue light emergency phones, illuminated pathways, and clear wayfinding signage.

Portland International Airport – Rental Car Quick Turnaround Facility (Envision Gold, 2021)

This Rental Car Quick Turnaround Facility was designed and built to streamline rental car fueling, cleaning, and inspection operations. Alongside this core objective, the project incorporates a highly water-efficient design that significantly reduces potable water usage compared to traditional rental car facilities. Rainwater harvested during Portland’s rainy season supplies much of the facility’s water demand, while an on-site well tapping a non-potable aquifer supports operations during the dry season. To maximize energy savings, the design team incorporated automatic lighting controls whenever possible, with interior lighting controlled by occupancy sensors.

Envision Alignment at the Owner Policy Level

Envision is increasingly being incorporated into airport owner policies and capital planning frameworks. For example, at Denver International Airport, Envision has been adopted at the policy level, with horizontal infrastructure projects exceeding $10M in total construction cost expected to apply the framework. This approach builds on lessons learned from individual Envision-verified projects and supports consistent, organization-wide consideration of sustainability and resilience outcomes.

Similar policy-level adoption has occurred at other agencies such as the Port Authority of New York and New Jersey (PANYNJ). For examples and guidance on owner-led adoption of Envision in the airports sector, we invite you to consult ISI’s Envision & Airports: Insights, Resources, & Opportunities Guide (AIRO Guide).

▸ Users are also invited to consult the Envision Policy Map for policies and other documents that require, incentivize, or encourage the use of Envision in infrastructure projects at various government levels.
