Energy conservation

REGULATING ENERGY DEMAND

As well as being an independent generator of power from renewable sources in several countries, EREN Groupe invests in innovative solutions to save energy. Tools to prevent costly and polluting consumption at peak times are reliable, effective and readily available: EREN Industries strives to implement these solutions for all consumers.

 

VOLTALIS

Through its subsidiary Voltalis, EREN Industries promotes and participates in the development of innovative technologies to better regulate energy demand through the installation of a proprietary box. This technology allows residential and commercial customers to regulate and reduce their electricity consumption.

 

COLD STORAGE: AN UNTAPPED ENERGY SAVING POTENTIAL

One of the largest uses of electricity in the world is cooling, the need for which is increasing every year with the scale of the equipment and with global warming. Needs vary considerably depending on the time of day, the season and the application (hotel, hospital, shopping centre, theatre, manufacturing industries, data centres, etc.). Conventional refrigeration systems are sized to cover peak loads, which are on average only 3% of the time. With cold storage, it is possible to substantially reduce the oversizing of conventional refrigeration systems.

Optimising cold management is therefore a key issue for industries, service sector companies and public players. Through its specialised subsidiary FAFCO, EREN Industries is at the heart of the modernisation of thermal management installations. The proven performance of the cold storage technologies developed by FAFCO makes it possible to cover peaks in demand and thereby reduce the electricity bill. These savings in operating costs also have a strong environmental impact (noise, cooling water, vibrations, space requirements), and consequently affect greenhouse gas emissions.

FAFCO: An innovative cold storage solution

FAFCO was founded in 1981, having first developed solutions for solar thermal energy, heat pumps and then thermal energy storage. Since then, FAFCO has become an expert in cold storage solutions with its ICEBAT accumulators, which service the air conditioning and refrigeration needs of industry.

ACCENTA: Making low-carbon heating and cooling more viable

Heating and cooling account for 10% of global carbon emissions. Accenta was founded with the idea of using the potential of AI and Data Science to make the drastic decarbonisation of building heating and cooling systems more attainable.
