Since 2018, photovoltaic power plan have been installed by ARGAN in our every new warehouses, for self-consumption, to fulfill tenants’ energy needs
What is new with Aut0nom® is the installation of a Lithium-Ion type battery system, a first in France for a logistics warehouse. Thanks to this equipment, the building is powered by green-energy locally produced and covering tenants’ needs in terms of heating and lighting over a year.
Aut0nom® is also the end of gas-use. Banned of all our new developments, it has been removed by air/air heat pump with an efficiency 4 times higher than gas boiler and, CO2 emissions divided by 20.
Lighting is provided by smart LEDs used for brightness and human presence, which allow us to divided by 8, the consumption of energy & CO2 emissions in comparaison of iodide lamps.
The CO2 emission savings resulting from the self-consumption of electricity produced by the photovoltaic power plant and its batteries fully-offset the low emissions from the heat pumps and LEDs.

Battery-based energy storage system
Aut0nom® is rented with its energy production and a battery-based energy storage system for self-consumption exclusively. This equipment has for effect to slightly increase the rent level due to the higher investment cost. In return, Aut0nom® generates energy savings on consumption fully-offsetting this cost. Savings are expected to grow due to the recent increase in energy prices, escpecially gas.
Moreover, this new warehouse standard, a virtuous production tool, will also benefit the CSR assessments of the site-operators.
Finally, the comfort of employees working in Aut0nom® is also significantly improved.
The warehouse is heated in winter and cooled in summer, which is a comfort element, not founded in gas-heated warehouses. Its rise in temperature is very fast, which allows a very reactive modulation.
Promising is good, but measuring and demonstrating is better. Aut0nom® includes equipment for measuring and displaying electricity consumption in real time. The percentage of electricity autonomy is displayed at each hour of the day. The operator benefits from this information and can adapt his own-consumption.
Jean-Claude Le Lan, Founder-Chairman of ARGAN : « With this new brand, Aut0nom®, ARGAN continues its commitment for a virtuous logistics real estate. It is a new step our Climate Plan, launched early-2020.
For us, the goal was to launch a standardizable product, carbon neutral for heating and lighting. In addition, the cost of equipment of our Aut0nom® warehouses is more than offset by the decrease in energy cost. This saving on the electricity cost will become more important in a context of soaring energy prices. Aut0nom® is a win-win contract, intended to become our new warehouse standard. »
