How FU0 - Operating a Datacenter during 1 year - works

Introduction

DCFootprint estimates the environmental impacts of the life cycle of the Datacenter, depending on its generic description (based on the input parameters), before computing the share of impact of each other Functional Unit.

This Functional Unit “0” is not defined in the Ademe Cloud & Datacenter PCR, but we choosed to present this part as a functional unit as well to make it more explicit and usable independantly from the other Functional Units.

Version 1

This is the very first version of the methodology. It will evolve in the future, but version 1 will remain usable, in order to be able to compare results between each model version.

To discuss about this methodology and how it should evolve, please look for an existing thread or open a new one, on community.dcfootprint.org.
