Project Overview
Oberlin College took a major step toward achieving carbon neutrality through the completion of its Sustainable Infrastructure Program, a comprehensive four-year initiative designed to modernize critical campus energy systems. The program replaced fossil fuel-based heating and cooling with a campus-wide geothermal system while transforming a century-old steam network into a modern hot water distribution system.
By integrating renewable energy with large-scale infrastructure improvements, the project significantly enhanced energy efficiency, reduced environmental impact, and improved year-round comfort for students, faculty, and staff.
Key Takeaways:
- Advanced Carbon Neutrality Goals: Transitioned from fossil fuels to geothermal energy as the campus’s primary heating and cooling source.
- Modernized Critical Infrastructure: Replaced outdated steam systems with efficient hot water systems and upgraded campus-wide utility networks.
- Significant Environmental Impact: Reduced water usage by 5M+ gallons annually, sewer discharge by 4M+ gallons, and improved energy efficiency by over 30%.
- Enhanced Campus Experience: Improved building comfort, system reliability, and expanded climate control capabilities.

56 Buildings Converted: Modernized residential, academic, office, and central utility spaces
5 Miles of Distribution Piping: Installed underground infrastructure to support campus-wide energy delivery
850 Geothermal Wells: Supported by 96 miles of heat exchange piping
Measurable Environmental Impact
The sustainable infrastructure program supports Oberlin College's long-term sustainability goals while reinforcing its leadership among institutions participating in the commitment to achieve carbon neutrality.
Building on previous sustainability initiatives—including energy efficiency improvements, expanded solar generation, and the transition from coal-fired heating to natural gas—the program delivers measurable environmental benefits, including:
- More than 5 million gallons of annual water savings
- More than 4 million gallons of annual sewer discharge reduction
- Greater than 30 percent improvement in campus energy efficiency
These outcomes significantly reduce greenhouse gas emissions while creating a more resilient and sustainable campus infrastructure.
Balancing Infrastructure Improvements with Campus Stewardship
Careful planning ensured the project aligned with Oberlin College's commitment to environmental stewardship. Where tree removal was necessary to accommodate new infrastructure, the College implemented a replacement strategy that exceeded the number of trees removed.
Working closely with the campus arborist and grounds department, the project team routed new energy distribution systems to minimize impacts on healthy trees and preserve the campus landscape. Tree replacement efforts prioritized:
- Compliance with city guidelines
- Ohio native and diverse species selection
- Long-term ecological health, structural integrity, and campus aesthetics
Advancing Learning and Campus Life
Beyond campus utilities, the initiative enhanced student learning opportunities and improved the day-to-day campus experience. Students played an active role throughout the project, gaining hands-on learning, research, and internship opportunities across disciplines including:
- Environmental studies
- Geology
- Economics
- Psychology
- Business
The modernization also strengthened campus operations by replacing the aging steam system with modern infrastructure that delivers more reliable performance, greater operational flexibility, and improved indoor comfort across campus.
Collaboration at Every Stage
The success of the Sustainable Infrastructure Program was driven by close collaboration among college leadership, trustees, faculty, staff, students, community partners, and local officials. Throughout planning and construction, the project team worked closely with city departments—including public works, fire services, and sustainability offices—with support from the City Manager and City Council to deliver this complex infrastructure transformation while minimizing disruption to campus operations and the surrounding community.
Executed over four phases, the program included the renovation and mechanical conversion of campus buildings, featuring:
- Residential, academic, administrative, and historically significant buildings
- Retrofit of existing spaces with modern hot and chilled water systems
- Construction completed during compressed 10–12 week summer windows
- Facilities returned to full operation before the start of each fall semester
A Blueprint for Carbon-Neutral Campuses
More than an infrastructure upgrade, the initiative demonstrates how higher education institutions can modernize aging systems while advancing ambitious sustainability goals. Through renewable energy integration, campus-wide system upgrades, and collaborative project delivery, Oberlin College has established a replicable model for carbon-neutral campus transformation.
