By developing eco-design

Saving energy comes first and foremost through design of our infrastructure and software. We monitor the power, heat generation and footprint of servers to optimize our technologies as much as possible. For our software, we make the choice of technologiesrennes and efficient:  

• Dynamic adaptation of the platforms to the load, until complete extinction in the event of non-use 

• Implementation of caches to limit redundant calculations 

• Limiting the use of unnecessary dependencies 

With regard to our infrastructures, we select equipment to improve our energy consumption and our CO2 emissions: in particular, we use hyperconvergence technology which allows the highest density of virtual machines on the market. 

To go even further in the process, the Luminess Group is signatory of the Planet Tech'Care charter since 2021. This charter makes it possible to support companies that are part of a responsible digital approach, which undertake in particular to measure and reduce the environmental impacts of their digital products and services, and to raise awareness among employees so that everyone contributes to reducing environmental pollution. impact of digital technology on the environment.

By reducing the sending of our emails 

Every day, 10 billion emails are sent in one hour worldwide, which corresponds to 4000 round trips Paris/New York knowing that 80% of them are never open. A single email produces no less than 10g of CO2, or even 19g if accompanied by an attachment, making its environmental impact considerable. 

To fight against this silent pollution, we have set up since 2019 on “No Email Friday”, an approach that encourages employees not to send e-mails internally on Fridays and to favor other means of communication. 

Reducing the sending of emails is part of our incentive agreements. Mailings are measured each month to meet this strong ambition. 

By optimizing consumption in our Data Centers 

Controlling the energy consumption of our data centers is essential. This requires optimal use of energy.  

• Server temperature is regulated : internal cooling is done according to the calculation load, the disks are stopped during periods of inactivity, the temperature is adapted to the seasons (summer / winter), and the air conditioning has been lowered by 1° in our data centers .  

• At the same time, we have increased the number of Nutanix nodes to reduce the consumption of our servers, and we have partitioned our data centers to Mayenne.

By giving a second life to our IT equipment 

We have implemented an eco-responsible and united approach by making donation of our computer and electronic equipment to our employees on our sites Mayenne, Lens, Rennes et Paris, or associations. An approach is carried out in an ethically responsible framework, and the material given is completely erased. 

The Group has also partnered with a operation organized by the CCI Mayenne and Orange which allows redistribute obsolete mobile hardware of the company and that of our employees. The equipment is repackaged in an integration workshop in France, a member of the Emmaüs Movement, then resold in an emerging country as a second-hand model. Otherwise, it is recycled, the hazardous materials treated and the metals recovered. THE profits from the operation are donated to Emmaus International which uses these funds to create mobile waste collection workshops in different African countries. Another partnership with Emmaüs.
