Standing column well geothermal energy (PCP)

The Clé-des-Champs school project at the Mille-Îles School Service Center, the first institutional building in Canada to integrate standing column wells (PCP), is intended to be a direct response to the desire to make an important shift in terms of energy consumption.

Innovate with what is under our feet

This innovative principle makes it possible to efficiently heat and cool an indoor environment by directly using groundwater which exchanges heat with the ground by conduction and advection.

System performance can be increased tenfold when tapping is activated, a process by which undisturbed groundwater infiltrates the well through the network of fractures in the rock.

Undeniable advantages

The great advantage of PCPs is the significant reduction in the number of wells to be installed in the field compared to a closed-loop well system.

Its use is therefore possible in small spaces where geothermal energy was not until now even an option.

PCP geothermal energy opens the way to new markets thanks to the reduction in the initial investment and the reduction of its footprint. In addition, this will ultimately reduce pressure on the electricity production and distribution network while combating greenhouse gas emissions.

    Reduction of greenhouse gas emissions

  • 80%

    Reduction of electrical power demand
    (versus an electric resistive heating system)

  • 42%

    Reduction of energy consumption
    (versus the existing)

A system that responds to the climate transition

PCP geothermal energy responds to “THE” main demand from Hydro-Québec, namely the reduction in the demand for electrical power during peak periods. PCPs make it possible to decarbonize buildings while responding to this issue, in addition to significantly reducing the energy consumption of buildings which represents 35% of all energy consumed in Quebec and the energy bill of owners.
