Comparing two designs in One Click LCA allows you to analyse their environmental impacts side-by-side, providing valuable insights for decision-making. This article explains how to create comparative charts, the limitations of Excel summaries, and how to generate detailed comparative reports.
The ability to generate a comparative report between the baseline and proposed designs is essential for LEED and CalGreen assessments, helping to meet the goals of this type of analysis. One Click LCA also offers broader comparative analysis tools that allow users to visualize and document the environmental performance of multiple designs within a project.
This feature is available in the following tools:
LCA for LEED Int'l
LCA for LEED, US (TRACI)
LCA for LEED, Canada (TRACI)
LCA for CalGreen (US)
How to Create Your Report
The Excel summary in One Click LCA only displays data for a single design and does not include comparative outputs.
To create your comparative Word report, navigate to the results page of your proposed design. On the results page, click on 'More actions' in the top-right corner: Before proceeding, ensure that both the baseline/reference design and the proposed design have been added to your project. You can do this by copying an existing design or adding a new one from the project’s main page.
From the drop-down menu, select 'LEED comparative report' (if CalGreen tool is used, the it will show as 'CalGreen comparative report'):
A pop-up window will appear, like the one shown below:
In this window, you will need to select your baseline design. Ensure that the baseline design accurately represents the reference scenario for comparison. This step is crucial for generating meaningful and accurate comparative results.
Finally, by clicking on 'Download', a Word file containing the comparative report for your proposed and baseline designs will be downloaded.
