Underground Utility Mapping Taking Place Across Dartmouth Campus

By District Energy posted 07-27-2023 07:38




A crew using a specially equipped truck is working at various sites on campus for the next week, checking the location of underground utilities as part of the continued campus conversion from steam to hot-water heating.

The switch to hot water is taking place in more than 100 buildings across campus as Dartmouth transitions from a central heating plant and steam-heating system to newer energy technologies that will significantly reduce the institution’s carbon footprint.

Dartmouth is transitioning over the next decade to a new energy-generation and distribution system designed to reduce the emission of greenhouse gases. A major component of the work is converting from steam heat to hot water, which improves efficiency and is adaptable to future technologies.

Hot-water systems have been installed in eight buildings since the start of the conversion work more than three years ago, O’Hern said.

As the campus hot-water conversion is expanded, Dartmouth plans to eventually phase out its oil-fired steam system and replace it with low-carbon methods, such as geo-exchange and solar thermal systems.
