Chapter 3: Build your Share project

Summary
Description

Share projects consist of two tabs: Overall results and Project scenarios

  • Under the Overall results tab, you can add general project information, findings, instructions, and you can create hotspots. 

  • Under the Product scenarios tab, you can build scenarios, analyze and compare their environmental impact.  We will describe how to create all those elements in this chapter.

Practical example
Hotspots are usually the object of study. For example your client is a procurement manager and are wondering which types of materials they should use for their new jeans. Then you, as an expert, can make an LCA model which takes into account all the parts of a jean and add it to Share. In Share the procurement manager could see the effect of the choices which are made. In this case, the material type is the hotspot.

 

Add project information

Under the tab Overall results, there are three text sections (by default called: Findings, Hotspots and Background) where you can add background information about the project or instructions to the business users.

All section headings and content can be edited by expert users and will be seen by the business users you assign to your project. Note! That the business user can only view and not edit this text.
 

Add hotspots

From the Overall results tab, you can also create and view hotspots. Hotspots are the primary variables you wish to investigate- for example, the main contributors to environmental impacts or types of materials.  .

When creating a hotspot, you define what changes users are allowed to make to create various scenarios. Possible changes are:

  • Replacing a process with another process (input process)
  • Adapting the value of a parameter


In the next step, you need to define the hotspots, the choices available to the user and the alternatives. A hotspot could be the material(s) your product is made of. You may want to give users a possibility to determine whether the product is made of one or two materials – in that case you have to define two choices.  For each choice, you then set a number of alternatives the user can choose from: for example wood, glass, or PP.

To create a hotspot:

  1. From the Overall results tab, click  + Add hotspot.
  2. Add a name and description of the hotspot and press enter.
  3. Click Add new choice. Give the choice a name and describe the question (as guidance to the business user).
  4. Select whether you want to vary an input process or a parameter value.

 

Input types that can be varied

Input process: Change the input of a process to another material/ process.  For example, replace European Electricity by US Electricity, or replace oak wood by pine wood.

Parameter value: Change the value of a parameter in your SimaPro model.  For example, allow users to choose the value of the parameter delivery_distance_km or user_large_truck, that you had defined in your SimaPro model.


If you choose to vary an input process:

  1. Click Parent process and select the process to which you want the changes to be applied (i.e. the parent process).
  2. Click Input to vary and specify which process you want to replace.
  3. The default amount shown is based on the value you added in your SimaPro model. This cannot be edited.
  4. You now need to add alternatives to the choice. Click Add new alternative and give the alternative a name.
  5. Select Alternative process and specify the process you want the user to be able to replace the default with. If you want to add a process from a library, you will need to tick the box 'Show library processes' at the bottom of the window.
  6. If desired, change the default amount.
  7. Select the checkbox Make amount editable by business user if you wish the user to be able to adapt the amount of material. If selected, set the minimum and maximum values the user can enter.
  8. All entries are saved automatically; click Back to return to the Overall results tab.
  9. Repeat the steps above to add as many alternatives, choices and hotspots as you wish.
  10. To delete a choice or an alternative, drag it fromUser-added imageand drop it in the Trash.


If you choose to vary a parameter value:

  1. Select the Parameter to vary from the list of available parameters
  2. The default amount shown is based on the value you added in your SimaPro model.
  3. Select the checkbox Make amount editable by business user and set the minimum a maximum value the user can enter.
  4. All entries are saved automatically; click Back to return to the Overall results tab.
  5. Repeat the steps above to add as many alternatives, choices and hotspots as you wish.
  6. To delete a choice or an alternative, drag it from User-added imageand drop it in the Trash.

 

Build scenarios

After you have created hotspots, go to the tab Product scenarios.  There you will see that there is already one scenario created for you.  This is the baseline scenario, which contains the default amounts, as you had defined in your SimaPro model (these cannot be edited). You can edit the name and description of the baseline scenario, by clicking the name and description.

As an Expert, you can build as many additional scenarios as you wish for your Business Users.  When you build a scenario, you basically vary the choices and alternatives you had defined for every hotspot.  To build a scenario:

  1. Click + Add new scenario.
  2. You can edit the name and description of the scenario.
  3. The scenario still contains the default values of the baseline scenario.  You can edit these by clicking the grey boxes. Click Save.
  4. Note! The grey boxes become a darker shade, indicating that the value selected differs from the baseline scenario.
  5. Repeat the steps above to build more scenarios.


After setting up the hotspots, the Expert can share the project with business users.  This is further explained in the following sections, but it is good to keep in mind the differences between these roles:

Expert users

  • Can add scenarios before and after publishing the project (scenarios created by the Expert user are visible to all assigned users)
  • Can view all scenarios made by business users
  • Can delete scenarios made by business users


Business users

  • Can build their own scenarios after the project has been published
  • Can only view scenarios created by themselves and by the Expert user

 

View impact assessment results

At any point while working with your scenarios, you can calculate the impact the impact of one scenario, or compare two or more scenarios. The impact of the baseline scenario is already shown and has been calculated based on the settings you had selected earlier in Flow.


There are several interpretation options:

Graph with a single scenario: allows insight into the hotspots and can be filtered per impact category (if defined in the calculation settings).  Make sure to select only one scenario.

One selected scenario

Process contribution: allows insight into the processes that contribute the most to the impact.  This option is only possible when you are analyzing one single scenario.

Graph with multiple scenarios: allows the comparison of two or more scenarios.  You can select as many scenarios as you want, by selecting the checkboxes.

Two selected scenarios


You can download a copy of the chart as an image by selecting Download Charts . You can also export the results and scenario information to Excel (as .csv) by clicking Download Scenarios                                             .

​​​​​Calculation settings

If you wish to modify the settings of the calculation you had defined initially, you can do so by clickingAdjust Settings at the bottom of the chart. Available options are:

  • Changing the LCIA method.
  • Changing the Normalisation and Weighting sets, if available in the LCIA method selected.
  • Selecting which information to display between Characterization, Normalisation and Weighting (depending on what's available for the LCIA method selected), and the level of cut-off.
  • Limiting (or not) the indicators visible, and hiding (or not) the baseline scenario.
