We have pioneered geothermal heat exchange systems since the early 2000s. The USA’s leaders across the technology, our specialist team’s successful projects include QA/QC on the largest energy foundation system in the USA in a Bay Area tech company’s global HQ, and Cornell’s applied tech campus borehole solution in NYC. Whatever your property type, we can offer a suitable solution.

The temperature of the earth below 6 feet remains constant year-round and reflects the location’s average air temperature. A ground source heat pump (GSHP or ‘Geothermal’) extracts warmth from the ground in winter, and in summer it recharges it with the building’s excess heat, cooling the building. Plastic piping loops circulate a liquid enabling this simple heat transfer.

Increasingly, states (such as NY, MA, and CA) view heat pumps as key to the electrification of the grid. Generous incentive programs give some geothermal systems cost-parity with conventional heating, on top of the significant environmental benefits.

To be cost-effective, we do not design to manage ‘peak’ heating or cooling. We manage base thermal loads, then use supplemental technologies to manage peaks. Solar thermal, air source heat pumps (ASHPs) or CHP can all be paired with a geothermal system to achieve cost-effective outcomes.
