DesignBuilder LEED v4 reporting "Subscript out of range"

asked 2022-09-19 14:50:25 -0500


I am doing an energy model as LEED v4 compliance modelling in DesignBuilder v7.0.2.004, to receive "Optimize Energy Performance" credits and to comply with the "Minimum Energy Performance" prerequisite.

The building is rather large (10+k m2), and I receive the error in the title when I want to generate the report sheet. Memory is not an issue, peak memory pressure was approx. 17 GB with a total of 128 GB RAM available in the desktop PC running the simulation.

Does anyone have an idea how to troubleshoot this? I have no idea how to solve it, as the error message is so vague and the amount of data generated is tremendous.

This looks like an issue in the code for the reporting script. This is typically something that happens when you try to index an array but pass an out-of-bounds index.

Thanks, Julien! The issue is that the mentioned script is a black box, I have zero control over it - you can just click the "generate LEED report" button on the UI, it starts loading and then the message comes. I assume there is not much to do other than contacting the DesignBuilder team for further info.

It is a bug. You can submit the issue to DesignBuilder on their support desk.

A follow-up on this topic, Shaun investigated the model and turned out, that some checks in the Summary Annual Reports tab were not checked, I haven't paid attention to keep this consistent between the Baseline and Proposed models.

You can find more about this on page 41 in the LEED and ASHRAE 90.1 2007 and 2010 App G PRM - User Guide PDF, it recommends more inputs to add for the LEED report generation.
