The Define Units task enables you to customize the standard units included with ARCHIBUS. Using this task, you can add, edit, or delete units for use with protocols or source consumption values.
If you will be entering consumption or factor data in units other than the default unit, enter those units here.
When defining factors for your background data or when entering your consumption and source data, when you click Save, a workflow rule runs. This workflow rule searches for the conversion factor for the unit type. Then, the application applies the conversion factor to the entered value, and returns the converted value.
Note: Because Units are stored as records in the database and not as an enumeration list, they are not translated as part of the core. To provide Unit values described in other languages, the Business Process Owner can enter values for translated Units as needed. The translated Units you enter are included in the Units list when users are making entries.
The ARCHIBUS Carbon Footprint is a flexible process that enables you to store entries using multiple units that you define. The application stores both the user-entered value in the user-specified units, and the base units value in the units that the Carbon Footprint workflow rule calculations expect. When you save a record using units other than the storage units, the view calls a workflow rule to convert the user-entered values into the base storage unit value.
Since the base storage units do not need to be converted, they have a conversion factor of 1.0. The base storage units are:
| Unit Type | Storage Unit Description |
|---|---|
| FUEL CONSUMPTION | Scope 1 Stationary Fuel Combustion (m3) |
| DISTANCE-MILES | Distance measurements (miles) |
| ELECTRICITY CONSUMPTION | Electricity usage (kWh) |
| WEIGHT-LBS | Weight measurement (lbs) |
| VOLUME LIQUID-GAL | Liquid volume measurement (gallons) |
| eGRID CO2 EMISSIONS | Energy Grid CO2 Emissions (Kg/kWh) |
| eGRID CH4-N2O EMISSIONS | Energy Grid non-CO2 Emissions (Kg/kWh) |
| FUEL DENSITY | Fuel Density (Kg/m3) |
| HEAT CONTENT | Fuel Heat Content (MJ/Kg) |
| CARBON CONTENT | Fuel Carbon Content (Kg/GJ) |
| FUEL EMISSIONS | Fuel Emissions (Kg/GJ) |
| MOBILE CO2 EMISSIONS | Mobile vehicles CO2 Emissions (Kg/Mile) |
| MOBILE CH4-N2O EMISSIONS | Mobile vehicles non-CO2 Emissions (g/mile) |
| AIRCRAFT FUEL CONSUMPTION | Company-owned Aircraft Fuel Consumption (gallons/hour) |
| REFRIGERATION EMISSIONS | Refrigeration/Air-Conditioning Emissions (Kg) |
| SOLID WASTE EMISSIONS | Solid Waste Disposal Emissions (MTCE/Ton) |
| WASTE WATER EMISSIONS | Waste Water Treatment Emissions (mg/gallon) |
| COMMERC AIR CO2 EMISSIONS | Commercial Aircraft CO2 Emissions (Kg/mile) |
| COMMERC AIR CH4-N2O EMISSIONS | Commercial Aircraft non-CO2 Emissions (g/mile) |
To define units:
The Define Units form appears.
Unit: Enter the unit of measurement or ratio to be used for this unit. If you need translated values for units, enter a translated value here. Enter a different record with a translated Units value for each language you want to make available in the selection list. For example, for the Aircraft Fuel Consumption Unit Type, you would enter liters/hours for an English language Units selection, and another record for liters/stunde to create a German language selection for liters/hour.
Conversion Factor to Storage Unit: Enter the conversion factor used to convert values entered using this unit to the base storage units. The conversion factor is the multiplicand used with the value entered to convert to the storage units. The formula is: {entry value in entry units} * {conversion factor} = {common database value in storage units}, where the conversion factor is taken from the entry you make in this field.
Default: Select Yes to make this the default measurement that appears first in the Units list for data using this unit type. If you select No, the unit is not listed first, but you can still select it from the Units list when adding data measured in those units for that type of data.
Description: Enter a description for this unit, such as kilograms per megawatt-hour. If you are translating this application, enter values with a translated Description.
