In eToolLCD, we have 2 main LCI group/datasets.

  • eTool Default


The two LCI groups are very different from each other. They have their own set of materials and equipment/people list and can not be used interchangeably within the same project. Therefore, when adding a template to a Design, you won’t be able to see or add a template that is different from the LCI group that you’ve defined for your project.

The ‘BRE IMPACT’ dataset is specifically for BREEAM assessments whereas the ‘eTool Default’ dataset is suitable for all other rating schemes. Please pay attention to the ‘LCI Group’ of the template when you’re reviewing templates in the library to know which templates will be available for your design.

If you have created your Project/template using the wrong dataset or if you wish to switch LCI groups, please refer to this support post.

eTool Default – LCI Sources

Under the ‘eTool Default’ LCI group, there are a number of sub- LCI Sources as per the list below:

  • Australasian
  • European
  • Global
  • New Zealand
  • North American
  • United Kingdom

These LCI Sources relate to the location of the project and provide more refined LCI data for industry average transportation/shipping distances for various construction materials.

eTool Default – Electricity, Gas, Water & Waste Water Grids

The eTool Default group also has a set of grids that can be specified independently of the LCI Sources. For example, you can have an Australasian LCI Source Project with an ‘EU Poland’ electricity grid. This ability to ‘mix-and-match’ allows some flexibility to help refine the LCA study to more accurately match the location & grid intensities of the Project. If this approach is used, the study author must be able to provide reasonable justification for the selection to study audiences and/or the reviewer.
