Create New Internal Factors
-
Click the New button to display the Factor slide-out.
-
Fill in all required fields. These fields are not required: Description, Uncertainty, Source, and CO2 Other.
If the CO2e Total field is populated, you do not have to populate the CO2 Value, CH4 Value, and N2O Value fields. If these fields are populated, the CO2e Total field is not required. The CO2e, CO2, CH4, and N20 entries must be positive numbers.
NOTE: All numeric field entries can have a maximum of 13 decimal places.
To use an internal factor as an electric grid for a site, ensure the following conditions are met:
-
Enter a factor Name. For supplier mix factors, the name must contain Supplier Mix or Supplier_Mix, for example, Electric_Cleveland_Supplier_Mix. For residual mix factors, use the same naming convention and replace Supplier with Residual, for example, Electric_Cleveland_Residual_Mix.
-
Ensure that the Region field entry matches or is higher than the site the factor is assigned to. For example, if the site region is Florida, the internal factor region can be Florida or the United States.
-
In the Source LCA Activity field, enter electricity_generation.
-
In the Category field, enter Electricity.
-
In the Sector field, enter Energy.
To use an internal factor as a heat and steam source for a site, ensure the following conditions are met:
-
Enter a factor Name. There are no naming restrictions for heat and steam.
-
Ensure that the Region field entry matches or is higher than the site the factor is assigned to. For example, if the site region is Florida, the internal factor region can be Florida or the United States.
-
In the Source LCA Activity field, enter use_phrase or unknown.
-
In the Category field, enter Heat and Steam.
-
In the Sector field, enter Energy.
Internal factors assigned to an electric grid or heat and steam source display on the Home page in the Utilities tab for data entry.
Emission Weight
All gas emission weight drop-down menus default to kilograms. To change the gas emission weight, you must select a unit from each drop-down menu individually.
First Unit and Second Unit
If the Unit Type selected requires two unit selections, such as AreaOverTime, the Second Unit drop-down menu displays.
