Summarizing Emission Calculations

To calculate emission totals for all Scope 1, Scope 2, Scope 3, and Other Emissions, the application summarizes data for all your footprint scenarios, calculation years, and locations. Archibus accomplishes this using the Summarize Emissions action. The Summarize Emissions action is available as:

a task - Carbon Footprint - Review / Summarize Emissions task. This task is available as you generate reports.
an action button found on the Enter Building Footprint Data - Building Details tab, or from the Building Footprints panel. These actions are available as you enter consumption data for any of the sources of your building's greenhouse gas emissions.

Summarize Emission Totals

The Summarize Emission Totals action triggers the Summarize Emissions workflow rule in the GBFootprint.java file. This workflow rule adds all the Scope 1, 2, 3 and Other Emissions values, and updates the total emissions values for this building, calculation year, and scenario in the GB Footprint Totals table.

This update of emission total is done either for the selected building, footprint scenario, and calculation year, or for all records that exist in the database:

When you run the Summarize Emissions Totals task from the Carbon Footprint - Review process or from the Building Footprints panel, the application does this update for all scenario footprints.
When you run the Summarize Emissions action from the Building Footprint Details tab, the application does this update for the currently loaded building footprint record only.

Running the Summarize Emissions action presents the Summarize Emissions Job Report View from which you run the job that summarizes emission totals. You can view the progress of the job from that window, and can continue working while the job runs. See Running Jobs.

Run the Summarize Emissions action whenever you:

Add or edit any footprint source records.
Delete any footprint source records.

From the Summarize Emissions Job Report view, you can select to run the Calculate Emissions workflow rule in addition to Summarize Emissions by selecting the Also Recalculate Emissions check box. See Recalculating Emissions.

Recalculating Emissions

When you run the Summarize Emissions action, you are presented with the Summarize Emissions Job Report View from which you run the job that summarize emissions. This job view includes the Also Recalculate Emissions check box that you can use to recalculate all the emission amounts for each footprint source record using any new or modified background data or versions.

This recalculation is done either for the selected building, footprint scenario, and calculation year, or for all records that exist in the database:

When you recalculate emissions from the Summarize Emissions Totals task or from the Building Footprints panel, the action updates all the existing emissions calculations in the database for all the footprint scenarios.
When you recalculate emissions from the Building Footprint Details tab, the action recalculates emissions for the selected building, year, and scenario only.

Recalculating emissions might take a considerable amount of time, so select this option only if you have

Added, modified, or deleted data using:

Any of the tasks in the Carbon Footprint - Background data task
The Building Footprint Details tab of the Enter Building Footprint Data task.

For example, emissions would need to be recalculated if your Business Process Owner makes any changes to the footprint protocols using the Carbon Footprint - Background Data task.

Your Archibus deployment might be set up so that this workflow rule is scheduled to run on a regular basis, such as once a day, or once a week. This workflow rule is in the GbFootprint.java file.

Calculating Emissions from a Single Source for a Building, Footprint Scenario and Year

Archibus includes a different Java file for each one of the footprint scope calculations, combining the calculations for company- and contractor-owned vehicles into one Java file. The Java files to calculate source emissions are:

GB FootprintScope1.java
GBFootprintScope2.java
GBFootprintScope3.java
GBFootprintCommon.java (for company- and contractor-owned vehicles)

These calculations are run when you enter and Save consumption data for a source of emissions using the Enter Building Footprint Data task. When you save the consumption data, the application runs the appropriate file and shows the calculated emissions in the Footprint panel for that source. See Entering Building Footprint Data: Overview.
