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.
