The default install of HBSI doesn't contain the AGS3.1 export mapping for ISPT Energy Ratio (ISPT_ERAT). To add this field to the AGS3.1 export mapping please see the details below:
You cannot manually edit the default mapping so to fix this you need to import the linked file to the configuration pack used.
First download the hbc found /cfs-file/__key/communityserver-wikis-components-files/00-00-00-01-05/1411.MissingImage.png
The open HBSI and login as the Administrator
Go to System>Configuration packs
Select the pack
Select 'Import Components"
Then browse to the downloaded file, select it and import it.
You can then open a project based on that configuration and export the Energy Ratio data as AGS3.1
