Ecodesign
From Wiki for Sustainable IT
Ecodesign of digital services consists of integrating environmental impact into design choices, from the initial specification through to decommissioning.
Principle
Most of a digital service's impact is determined at design time. Once a service requires a recent device, a fast connection and continuous data exchange, no later optimisation recovers what the initial choices cost.
Ecodesign therefore acts first on what is built, and only then on how it is built.
Main levers
- reduce the functional scope to what is actually used ;
- preserve compatibility with older devices, which delays their replacement ;
- limit the volume of data transferred and stored ;
- avoid designs that require constant network activity ;
- measure before and after, rather than assuming.
Frameworks
The RGESN provides a public reference framework of criteria. The GR491 provides a more extensive set of recommendations. Both are usable together: the first assesses, the second implements.
