Hi I want to study the impact of the light shelf on thermal-visual comfort in buildings. I don't want to use honeybee and ladybug or Radiance, I want to model this building with EnergyPlus and optimize it with another software. Could you help me, how can I use EnergyPluse in this regard and which data it wants? I look forward to hearing from you, ASAP. Many thanks Fatima

EnergyPlus has an DaylightingDevice:Shelf object type that should be used to simulate a light shelf. This will require drawing the following surfaces in the model's geometry:

When you install EnergyPlus, there is an example files folder that has IDFs (EnergyPlus input data files) for models that showcase nearly every object type available in EnergyPlus. If you open C:/EnergyPlusV9-5-0/ExampleFiles/ExampleFiles-ObjectsLink.html and search for the object type you're interested in, you should find one or more IDFs to review. For the DaylightingDevice:Shelf object, it looks like there is only one example file -- DaylightingDeviceShelf.idf.

You can also read a few other posts on Unmet Hours for modeling a daylight shelf in EnergyPlus here and here.
