US

As an external user I can retrieve the impact of my server With the bottom-up methodology of Boavizta

Route(s) involved

/v1/server/bottom-up

Process

The user send data concerning the server (model, brand, type, CPU type, CPU number, stockage capacity, ...). If all the data needed to apply the methodology has been given by the user, the impact is calculated and sent back to the user. If not, default values are used

Methodology

This methodology is a bottom-up approach to evaluate the manufacture impact of a server from the impact of its components. The impact of CPU, RAM and SSD are evaluated depending on their die density (which as been found as the most influent variable). The impact of the other components are evaluated directly with emission factors.

Equations

For CPU

GWP_Manuf_CPU (kgCO2eq) = CPUNumber (Unit) x ((CPUCoreNumber (unit) x DieSizePerCore (cm2) + 0.491) x CPUDieGWPImpact (kg CO2eq) + CPUGWPImpact (kgCO2eq) )   
ADP_Manuf_CPU (kgSbeq)= CPUNumber (Unit) x ((CPUCoreNumber (unit) x DieSizePerCore (cm2) + 0.491) x CPUDieADPImpact (kg Sbeq) + CPUADPImpact (kgSbeq) )  
PE_Manuf_CPU (MJ)= CPUNumber (Unit) x ((CPUCoreNumber (unit) x DieSizePerCore (cm2) + 0.491) x CPUDiePEImpact (MJ) + CPUPEImpact (MJ) )
