Apologies for the silly question- Does LBT 1.3 save the result files for HB annual loads, etc, as an excel file? If so, where does it save? It does not appear to save it in C:\ladybug or openstudio folders.
The results of energy simulations in LBT come almost entirely from the eplusout.sql files that are output by EnergyPlus. There are plenty of components that parse this sql file in the LBT plugin.
The Annual Loads component is really meant for quick checks of loads and load balances, so it always stores the results in the following location on Windows:
C:\Users\[USERNAME]\simulation\Annual_Loads
If you are doing more production-level energy simulations, you should be using the HB Model To OSM component to run the simualtion.
