Expansion and Improvement of A Critical Public Safety Facility

The Anoka County Emergency Communications Center keeps people safe every day of the year. The former facility was limited in space, sunlight, and technology. The new facility is meant to improve efficiency of operations and modernize the work space for critical government employees.

Modernizing the infrastructure starts with the work flow of employees, but quickly expanded to the underlying MEP systems. The project design goals were anchored in operational excellence and environmental stewardship to meet state funding standards. The team identified geothermal as an innovative approach that could deliver maximum efficiency for decades to come.

Optimizing Operational Efficiency and Economics

The decision to implement a groundwater enabled system was based on the ability to deliver high efficiency and meet funding state requirements. The building is utilizing a 135-ton, single-well groundwater central heat pump system to provide resilient heating and cooling. Physical space was optimized by placing the equipment at the back of the gated facility, easily accessible for O&M requirements. This design eliminated the need for larger land mass of traditional systems and ensures long-term ease of maintenance.

The facility is a remarkable improvement for 24/7 mission critical operations. Learn more about the design approach and results in the included case study.

How The Backbone of Naval Aviation Training is Testing New Technology to Improve Operational Resilience

As part of the ongoing efforts of the Naval Base, NAS Whiting Field is building a Darcy geothermal system to improve operating efficiency and further their mission by testing the technology. NAS Whiting Field Installation Energy Manager, Jason Poe, and Facilities Management Director, George Rials, and they indicated that this building would be a good fit for the demonstration.

With a current 60-ton air-cooled chilled water system, depending on the specific building details and its heating and cooling needs, the Darcy system could be sufficient to replace the existing system or supplement a hybrid system. In either case, the existing system could be left in place to provide full redundancy, if desired.

Next Steps: Mobilization and Construction in 2026

Given the need of military sites’ need to potentially island operations from utility grid, geothermal is an excellent electric options to couple with distributed energy systems such as solar and storage. The team is excited to construct and test this new design at NAS Whiting Field for operational efficiency and advancement of the their mission.

Darcy team members have completed a site walk of the facility in Q4 of 2025 and are currently working to finalize the design of the system with project partners and facility managers.

A Downtown Staple of Education Makes the Most of a Limited Footprint

Since 1971, this Milwaukee Library location has been a cornerstone of connection and growth. Now, a bold new chapter begins as the Dr. Martin Luther King, Jr. branch undergoes a significant revitalization.

Part of a catalytic mixed-use development, the new 17,400-square-foot facility is being rebuilt with a geothermal system—an innovative approach to sustainable water management and structural efficiency. This 21st-century library will anchor the King Drive corridor alongside a 42-unit apartment complex, blending modern infrastructure with a fifty-year legacy of community service.

Built to Perform In Peak Summer and Winter Climates

The first Milwaukee Darcy geothermal system was designed to provide sustainable heating and cooling for the mixed use requirements after the renovation was completed. The well was built in the parking areas at the back of the parcel, and only took the space equivalent of a half a parking spot. The project demonstrates how compact aquifer technology can be integrated into urban public infrastructure.

Library patrons and surrounding community are interested in sustainable, long term solutions which are both energy and economically efficient. Beyond the immediate energy savings, the system offers long-term reliability and adaptability, ensuring the Milwaukee Library facility remains efficient for decades to come.

Local Government Using Sustainable Solutions to Progress Against Community Climate Change Goals

For Rochester City Hall, the priority was a robust mechanical system that offers both innovation and high efficiency. City administration and the local community wanted to find technology that balances costs and can expand for electrification planning over the coming decades. The City Hall was the first of a kind project in Rochester that provided a foothold for future projects, including the potential for a Thermal Energy Network for other public infrastructure.

Optimizing Performance with Darcy Solutions

This project replaced historic City Hall HVAC infrastructure with a 2-well, 156-ton groundwater geothermal system to serve the municipal center. The building has been operating for various purposes for decades and today houses multiple government administrative functions. The installation supports the city’s commitment to 100% renewable energy for municipal operations.

Darcy Solutions was the clear choice for Rochester City Hall due to its innovative technology and efficient use of the parcels natural resources. The resulting system offers stakeholders a high-performance heating and cooling solution with proven long-term applicability.
