Is EnergyPlus the engine for all Ladybug Tools?

Hopefully a simple question, I’m wondering if EnergyPlus is the engine for DaySim, Radiance, OpenStudio? Just wondering if all recipes meet LEED standards?

Thank you,

@rismail88 You have asked similar question about LEED.

Honeybee-Radiance which is base Radiance V5 can be used for LEED daylighting simulation.
Honeybee-Energy can be used for LEED energy modeling, which used Openstudio as engine. Openstudio use EnergyPlus as engine.

You can use Ironbug Plugin to create HVAC system for LEED energy modeling。


Thank you, this is exactly the answer I was looking for.
