We want to model a house in SketchUp with the OpenStudio plug-in. This house has a basement. Ceiling height of the basement is +1.20 m, and then the is the next floor. My question is what kind of basement should I choose in OpenStudio?
The boundary conditions for slab and basement were meant for when you are using the ground pre-processor. You can find documentation on that here. http://nrel.github.io/EnergyPlus/Auxi...
If you are just making a basic model and not calculating ground temperatures then you would typically use "Ground" as the boundary condition. But that is of course not as accurate as calculating them on your own. EnergyPlus now as the ability to calculate ground temperatures during the main simulation vs. only as a pre-processor. With the built in method I believe you would generally end up with a boundary condition of "OtherSideCoefficients" then you would have to create an object to use as the Outside Boundary Condition Object.
