Is EnergyPlus the engine for all Ladybug Tools?

[rismail88]

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.

Can Ladybug Tools be used for Official Energy Modeling / LEED?

Thanks for the reply @minggangyin Maybe I worded it poorly, but I wonder if every recipe can be used for LEED. For example, HB-Radiance is used to calculate sun hours and sDA. Or sometimes, the recipes leverage Openstudio and Radiance and other engines to perform the calculations. Is EnergyPlus the main engine for every recipe and then openstudio is used alongside it to complete the calculations? So in those instances, would those be compliant with LEED? Thank you, Rahman

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。
