Geodel geothermal drilling site

Geodel
Geothermal

We design, drill and operate building-scale geothermal heating and coolingfrom subsurface survey to shared thermal networks. Built for dense American cities, starting in Philadelphia.

Who we are

Built for building-scale geothermal

Geodel works the full geothermal stacksubsurface intelligence, drilling, ground exchange, thermal storage and network operations. The physics is proven; deployment is the problem. Every system we design is engineered for repeatability across real American building stock, from a single multifamily retrofit to a shared campus borefield.

Solutions

Geothermal solutions for every building type

We match each borefield and loop design to the real thermal profile of the building and the geology under it.

Universities & campuses

Universities & campuses

Dense clusters of buildings with year-round simultaneous heating and cooling loadsthe strongest case for a shared borefield. We characterise the ground first, then size one loop field to serve many buildings.

Seamless journey

From first survey to a working thermal network

A staged process designed to take uncertaintyand costout of the ground before capital is committed.

Geophysics, hydrogeology and existing well data build a model of the ground before capital is committedgeology, groundwater and thermal conductivity.

Building load profiles are matched against subsurface capacity to place boreholes, size the loop field and design the exchange strategy.

Instrumented drilling with continuous logging, so each borehole informs the next and field time falls across the programme.

Distributed water-source heat pumps, hydronic distribution and controls brought online building by building with measured performance.

Loop temperatures, seasonal balance and heat-pump performance monitored continuously, then tuned across the network.

For building owners

Underground infrastructure built for long-hold assets.

See what the ground under your building is worth.

We model geology, thermal conductivity and building load before anyone puts a rig on siteso borefield size, drilling risk and payback are known numbers rather than assumptions.
