Type of assignment
Assistance to the client for the deployment of a smart heating and air-conditioning grid in a service-sector development area, as part of a Design Build Operate Maintain contract awarded to a private operator.
Assistance in designing the warm loop and generation of renewable and recovered energy (heat pump on underground water, water storage and storage by change of state, photovoltaic solar energy, hydrogen, absorption heat pump, etc.) aimed at achieving the minimum carbon content.

Description of the work
SERMET assists SEMAG in designing and implementing all the parts of the smart grid.
The production facilities present a high degree of innovation; the originality of the operation lies among other things in the existence of a considerable stock in a former mine shaft. The water is extracted by immersed geothermal pumps and heats or cools a warm water loop.
The warm water loop supplies six hot and cold water production substations, each featuring different innovation: storage tanks, water/water heat pump, cold water stored by change of state, solar absorption heat pump, fuel cell. A solar photovoltaic power plant on the roof delivers electricity to the geothermal plant and to the heat pumps of 4 substations through a dedicated electric loop. The system is controlled by a smart supervision system that optimizes the power demand of the different energies (ACCENTA technology).
SERMET has also assisted the Client in scaling the warm loop, which has managed to recover some of the existing networks.
Lastly, SERMET has fulfilled Title V of the smart grid and thereby determined the estimated carbon content, which will allow future buildings to benefit from low-carbon energy in thermal simulation tools.
The assistance, studies and consulting services provided allow the Client to steer the project towards smart, innovative, environmentally and economically efficient solutions.
The innovations implemented on each energy production site allows one to imagine what the smart energy networks of tomorrow could be.
