Central Washington University Earns 2026 Zero+ Champion of Sustainability Honors for Reimagining Campus Heating

At Central Washington University (CWU), progress is taking shape beneath the Ellensburg campus. CWU is developing a new geothermal plant that will use the Ellensburg Aquifer to provide heating and cooling while laying the groundwork for a broader transition away from its fossil-fueled central steam plant. McKinstry and Lumen Field recognize CWU as a 2026 Zero+ Champion of Sustainability for pairing that project with a 15-year decarbonization roadmap covering its entire campus.

Serving roughly 8,000 students, CWU has committed to reducing campus greenhouse gas emissions 45% by 2030 and reaching carbon neutrality no later than 2050. The challenge is significant: roughly 60% of the university’s emissions come from natural gas used to heat buildings through its aging central steam plant.

Tapping the Earth for Clean Energy

CWU’s GeoEco Plant is designed to make use of a resource already beneath the campus. Ellensburg sits above an aquifer with a relatively steady temperature year-round, providing a source of energy for an open-loop, ground-source heat pump system.

The plant will draw energy from the Ellensburg Aquifer to heat and cool the new North Academic Commons and additional nearby buildings without relying on fossil fuels for those loads.

The project is also designed as a living laboratory. Students and members of the public will be able to see the clean energy exchange in real time, connecting campus infrastructure with education and research.

Together with the retirement of two aging, inefficient buildings, the project is projected to avoid roughly 33,000 metric tons of greenhouse gas emissions over 50 years.

Planning for a Fossil-Free Campus

The GeoEco Plant is one piece of a much larger transition.

CWU developed a 15-year decarbonization plan for its Ellensburg campus, which includes 60 buildings totaling roughly 3.5 million square feet. The plan calls for phasing out the campus’s fossil-fuel-based central steam plant and replacing it with decarbonized mechanical systems built around geothermal energy, heat pumps and efficient electric infrastructure.

The roadmap is grounded in technical analysis, system comparisons, cost estimates and carbon and lifecycle analysis. It also considers the university’s capital planning and deferred-maintenance needs, connecting long-term climate goals with the practical realities of maintaining and modernizing a large campus.

The plan includes campuswide energy metering, energy management and operations and maintenance strategies, along with university engagement and an environmental justice assessment.

Turning a Climate Goal into a Campuswide Strategy

CWU’s approach moves beyond individual building upgrades by creating a sequence for addressing the systems that serve the campus as a whole.

The university is advancing building-level projects that put the roadmap into practice, including upgrades at Brooks Library, Science 1, Bouillon Hall, and Quigley Hall. Each project contributes to the larger transition while providing opportunities to improve building performance and address aging infrastructure.

This phased approach allows CWU to align decarbonization with planned capital investments, rather than treating climate work as a separate effort from the university’s broader facilities strategy.

Making the Campus a Living Laboratory

CWU is also using its transition as an educational opportunity.

The GeoEco Plant will give students a firsthand view of geothermal energy and heat pump technology operating on campus. More broadly, the university’s decarbonization work creates opportunities for students to engage with real-world questions around energy, engineering, building systems and climate solutions.

That connection between infrastructure and education is central to CWU’s approach. The campus becomes a place where students can not only learn about the clean-energy transition but observe and study it as it happens.

Zero+ Champion of Sustainability

Central Washington University is combining a near-term geothermal project with a long-term strategy to transform how its campus uses energy.

The GeoEco Plant provides a tangible first step, while the 15-year roadmap establishes a path for transitioning 60 buildings and roughly 3.5 million square feet of campus infrastructure away from fossil-fueled heating.

McKinstry and Lumen Field recognize Central Washington University as a 2026 Zero+ Champion of Sustainability for turning its carbon-neutral commitment into a practical campuswide strategy and using its transition to create opportunities for students to learn from clean-energy systems in action.
