In 2023, P3 Logistic Parks, one of Europe’s leading investors and developers of logistics real estate, is entrusting Accenta with the decarbonization of its 19,000 m² warehouses in Grand-Couronne, near Rouen.

As part of its energy transition, the company wants to replace its gas-fired heating system and reduce the use of fossil fuels as much as possible.



Tailor-made solutions from Accenta


The recommended solution is a geothermal system that captures heat from the subsoil, which is reputed to be clean, unlimited and non-intermittent.

The underground energy is then injected into the cooling and heating production/distribution circuits.


Work undertaken at the Grand-Couronne site has resulted in the installation of the following elements:

✅ A 5,800 m geothermal probe field (58 probes 100 m deep)

✅ 2 geothermal heat pumps

✅ 1 aerothermal heat pump



Benefits for the customer


P3 Logistic Parks now has total control over its energy consumption and is reaping the benefits of its geothermal installation:

✅ A significant reduction in energy bills and CO2 emissions

✅ Compliance with the BACS decree (obligation to install an automated building management system [GTB])

✅ Exceeding the low-carbon targets set by the tertiary sector decree (-40% CO2 by 2030, -50% by 2040 and -60% by 2050)

✅ Improved employee comfort

✅ An increase in the real estate value of the site

✅ An eco-responsible approach that enhances the company’s image

Tomorrow, green energy will no longer be an option
