Modelling Design Scenarios – branching design improvement strategies

We’re excited to introduce our new “Scenarios” feature in eToolLCD which enables running scenarios both concurrently and in parallel (branching).  This enables more accurate comparison between competing design options (and introduces a number of other advantages).  The demo video below outlines the feature quickly: 

The Scenarios feature allows branching of design improvements. It gives the use the ability to define the starting point for the scenario and explore different routes for project changes. For example, understanding the difference between the two different types of energy monitoring systems.

The benefit of this feature is the flexibility to model design strategies in parallel from different starting points, instead of a linear sequential order where an improvement is fully dependent on all previous changes. As the design progresses, the model can be adjusted with the appropriate starting point scenarios and the subsequent strategies can be considered, instead of having to remodel all recommendations again from the baseline design.


If your design doesn’t already have Scenarios by default (you see ‘Recommendations’ instead), the feature is enabled by navigating to the Recommendations tab and selecting Use Scenarios from the Action menu. The user can choose from using the standard Recommendations recording feature or change to Scenarios.

The design purpose label is indicated by the Blue circles (BAU, Proposed, Improved, Final). This feature automatically clones a new design each time link an improvement strategy to the chain, there is no need to ‘Record’ the recommendation.
The active scenario is denoted with the red arrow icon and inactive scenarios are shown with the grey icon. Users can branch various scenarios of an earlier scenario.

Note that you can’t branch upon branches ( you can only branch from the main branch) due to the complications this would create visualising the tree, particularly in reports.  

Notes on Using Scenarios

1) You no longer need to clone your Business As Usual/Reference Design to start modeling your recommendations

This is because the software now automatically clones it for you every time you ‘link’ a new scenario/recommendation to the tree/chain.

2) Each scenario design is independent and not linked each other once you’ve connected it to the Scenario Tree/Chain

What this means is that if you delete a scenario OR if you change a scenario at the top of the chain/tree where there are other scenarios below, all other scenario designs below that change will NOT reflect those changes you’ve made. So you will need to jump into each of the following scenario designs to make the relevant updates so that they are consistent with the changes made earlier in the chain/tree.

How to Define the final Proposed / Improved / Final Design

Once you’ve modeled all your scenarios, note that all scenarios moving down the chain are the accumulation of all previous scenarios.

Please refer to this support post on What Do the Different Design Purposes Mean.

To ‘finalise’ your Proposed/Improved/Final Design, you won’t need to create another scenario as the software will do this for you by following the steps below:

After you click on ‘Save’ the Scenario tree will automatically update with the final ‘Proposed Design’.

Streamlined Certification Process

With the new Scenarios Feature, we have also streamlined the quality check list to help speed up the review process for the Improved/Proposed Design.

The reasoning behind this is that once the BAU/Reference Design has been certified and locked, assuming that only then do you start modeling your Scenarios, all the reviewer has to do is to compare and comment on the difference/changes made between the Scenarios and the previously certified design. Items that have not changed will not need to be reviewed again.

Note: Only the Proposed, Improved or Final Design should be submitted for certification. When the Improved/Proposed/Final Design is being reviewed, all the preceding Scenario Designs will be reviewed to check that they have been modeled correctly since the Proposed/Improved/Final Design is defined by a collection of Scenarios as illustrated by the image below.
