High Performance Building Case Study: Ford Calumet Environmental Center

Nail-laminated timber project connects Big Marsh Park’s industrial past with local ecology

Project Overview

In 2021, the Ford Calumet Environmental Center opened in Chicago’s Southeast side. The LEED Silver building is located within Big Marsh Park, which is a part of the Chicago Park District’s largest reclamation projects.

Located within Big Marsh Park on Chicago’s Southeast side, the Ford Calumet Environmental Center celebrates the region’s environmental and cultural assets.


Big Marsh Park is a 300-acre natural and recreational space that has been damaged by more than a century of industrialization from nearby steel mills. Now, the park, opened in 2016, is one of Chicago Park District’s largest reclamation projects and home to a 40-acre bike park and walking trails.


The 9,300-square-foot LEED Silver project includes a bike repair area, nature exhibits, two classroom spaces, offices, restrooms, and storage spaces.


The center uses an on-site, constructed wastewater wetlands system, which uses the site’s wetland vegetation, soil, and other natural organisms to filter the building’s blackwater. This system, which isn’t connected to the City’s sewer system, is the first of its kind in Chicago and one of the first in Illinois.


A majority of the project was funded by a $3.7 million donation from Ford Motor Company, which owns a nearby assembly plant.

Spotlight on nail-laminated timber


Nail-laminated timber (NLT) is a durable, low-carbon alternative to building materials like concrete and steel, which are carbon- intensive during production. This lightweight material is well-suited for large floors, walls, and ceilings. In addition, NLT is less expensive than other mass timber materials, like cross-laminated timber.

Cost Effective Sewer Solution

“One of the things that pushed us into doing a high performance building was the fact that we had to come up with a solution to sanitary waste,” said Joe Valerio, Principal at Valerio Dewalt Train.


The site is roughly two miles from any sanitary sewer system, so the project team had to think creatively about how to solve this issue. Initially, the team estimated that it would cost nearly one eighth of the project budget to build a connecting sewer line to the site.


That’s when Valerio Dewalt Train sought out ecological restoration company, Biohabitats to design Chicago’s first constructed wastewater wetlands system. The system treats black water on-site and releases the nearly-potable water back into Lake Calumet.

Matterials Marry industrial past with nature

The building’s exterior is clad in a rain screen of weathered steel, which calls upon the site’s industrial past. In contrast, the interior structure is made of exposed nail-laminated timber, alluding to the project’s sense of ecological reclamation.

Exhibit connects past, present, and future


The building is home to an exhibit that tells the story of over industrialization; The display focuses on the park’s reclamation of natural habitats after decades of damage caused by nearby steel mills.

A building made with birds in mind

Given the marsh’s importance to migrating birds, it was essential that the building be bird friendly. This was made possible through operable hangar doors that shade the 10-by-10-foot windows when raised over them. When raised like this, the doors limit the chance of birds to mistake reflections in the windows for the landscape. Even when closed, the doors’ perforated metal allows 50% of daylight to enter the space.

Why is the environmental center important to the surrounding community?

The project centers local ecology, but also, importantly, the surrounding neighborhoods that have historically been burdened by pollution caused by steel mills and other industries. “As you walk through the exhibit you see photographs of some of the people that live in the surrounding communities, and their stories are reflected in that exhibition,” said Joe Valerio, Principal at Valerio Dewalt Train.

he mission of the Illinois Green Schools Project (IGSP)—our year-long school sustainability action and recognition program--is to empower educators, school administrators, students, and school communities to create healthy, sustainable learning environments. This work requires passion, collaboration, and informed support, and as an IGSP program coordinator, I’m always on the lookout for opportunities that help schools build the knowledge and connections needed to drive meaningful, lasting change in their buildings and districts. The Green Schools Conference has long been one of the most impactful gatherings in this space. Its focus on the intersection of environmental health, sustainability, and education makes it a uniquely valuable event for anyone working to make schools healthier and greener places for students to learn and grow. From educators, administrators, and district representatives to facilities managers, students, and community organizations, the Green Schools Conference is a powerful space to learn, collaborate, and fuel your next big idea. This year’s conference promises a rich lineup of workshops, education sessions, and networking and recognition events that speak to the needs and realities of today’s school sustainability landscape. Districts across Illinois are navigating shrinking budgets, aging infrastructure, and a newly passed state-wide law requiring the inclusion of climate education in public school curriculum starting in 2026. Therefore, I’m particularly excited to see sessions on the agenda exploring climate action and resilience planning, opportunities to connect students to sustainability career pathways, and environmental literacy in classrooms. These conversations are essential as programs like the Illinois Green Schools Project continue evolving to support schools in setting goals, tracking progress, and engaging diverse communities in sustainability work. If you’re considering attending this year, I encourage you to take a look at the agenda and explore the sessions that could support your school or organization’s goals. You’ll find no shortage of practical insights, creative ideas, and meaningful connections. I know those who attend will come away with the same clarity, inspiration, and sense of comradery that have made past conferences so influential for myself and others in the Illinois school sustainability community.

At the start of 2025, I told our members that we can build a movement of green building advocates that can continue the progress made in Illinois for high-performance building, regardless of what happens in Washington D.C. Over the last year, you’ve proven me right. While elsewhere green building and clean energy goals have been put on pause, Illinois has continued the fight and won three huge victories that completely change the landscape for green buildings and clean energy.
