Impact factors
The HDD disk manufacturing impact is considered as a constant.
| Constant | Unit | Value |
|---|---|---|
| \(\text{HDD}_{\text{embedded}}^{\text{gwp}}\) | kgCO2eq | 31.10 |
| \(\text{HDD}_{\text{embedded}}^{\text{adp}}\) | kgSbeq | 2.50E-04 |
| \(\text{HDD}_{\text{embedded}}^{\text{pe}}\) | MJ | 276.00 |
Info
If there are more than 1 HDD we multiply \(\text{HDD}_\text{embedded}^\text{criteria}\) by the number of HDD given in units.
Usage impact
