Using eToolLCD for ISCA RSO-6 Credit and Environmental Modelling of Infrastructure Projects

As many of you may have heard, the Infrastructure Sustainability Council of Australia (ISCA) published their Materials Lifecycle Assessment Guideline in May 2021 – see the ISAP Resource Page of the ISCA website.

eToolLCD users can now use the power of our software to model materials of infrastructure projects using eToolLCD in lieu of using the IS Materials calculator and generate reports for the RSO-6 credit (or Mat-01 v1.2 if using the v2.0.06 calculator (or later)). ISCA is in the process of approving eTool’s data alignment and validation work to ensure results are consistent with the IS Materials Calculator v2.0.06.

The LCA practitioner using eToolLCD on a IS rated project needs to comply with the minimum requirements from the ISCA LCA Guideline Rev 1.0. eToolLCD complies with the required standards as well as the technical specifications including: Environmental Indicators, Cut off criteria, Allocation and Normalisation and Weighting. Independent review conducted by eTool meets the LCA Review Guidance requirements.


How does it work?

  1. Create an account at eToolLCD if you have not yet.
  2. Complete the official eToolLCD software training for Infrastructure projects. This will ensure users know how to create an aligned project.
  3. Create an infrastructure project as per training guidance, carefully consider the Structures and Designs of your project.
  4. Select the latest version of the LCI source (v17 as of 21 Oct 2021, v18 coming soon!). If you don’t have the latest version, please submit a Support Request for access to ensure that your LCA has been aligned for ISCA reporting.
  5. According to EN 15978 standards, best practice LCA should include all life cycle modules A, B, C and D. However, for ISCA RSO-6 reporting only Life Cycle modules A1 to A5 and B2 to B5 are required to be in scope. In order to align your LCA study with EN 15978 but also to customise reporting to meet ISCA RSO-6 requirements, we have created some reporting templates that will do this for you. As such, when modelling your design in eToolLCD, you can leave all modules in-scope and export your results using the spreadsheet template provided by this download link. You can download an EN15978 table from the software and then copy and paste the numbers into the ISCA report template.
  6. Additional indicators are also required for the RSO-6 reporting. These can be switched on under the Indicators tab at the Project level for your project (Fig. 2).
  7. You will need to create both a Base/Business As Usual Design and an Improved/Proposed Design for your project. Guidance for modelling the base design can be found in the Materials Lifecycle Assessment Guideline that can be downloaded from the ISAP resources page of the ISCA website.
  8. Once your baseline model is ready, you can submit your LCA for certification. The normal eTool certification process will apply to ISCA projects. The certification process will also satisfy the requirements of an EN 15978 and ISO 14044 independent review. Ensure you complete the review of your baseline design first before creating the Proposed design with improvement initiatives. Specialist users have this cost included into their subscription. Users under other plans will need to pay an access fee to model their projects in eToolLCD and have them certified by our staff members.
  9. When creating a proposed design, ensure the project changes are tracked via the Scenarios feature. This will create an audit trial of changes made to the original design and will also inform the % impact savings for each design improvement. 
  10. Once your model has been completed and certified you can populate the reporting template (download link under step 5 or below) using the EN15978 Table Report(s) that can be generated under the ‘Reports’ tab at the Design Level of your project. Note that ALL Life Cycle Modules need to be included when generating the table because in the spreadsheet template provided below, the results table will automatically highlight which modules are required for ISCA. This is in order to remain transparent and align with EN 15978 standards while meeting ISCA requirements.
  11. LCA report to include Life Cycle Inventory appendix summarising key inputs and assumptions used for the LCA. 
  12. A Certifier Review Statement will be provided by eTool after completing the independent review.
