sww1235 Posted March 3, 2017 Share Posted March 3, 2017 (edited) Hello: I have a building with several insulated interior walls and so wanted to create a new "Object Boundary Type" as shown under Edit Wall Style -> Insertion Options -> Energos. I have created a new type, but I cannot figure out what the parameters R S External and R S Internal are used for. Even the units are confusing, sq ft F h/Btu. What are these parameters used for? Thanks in advance. Edit: After a bit more googling, these units appear to be inverse heat transfer coefficient, but what I cannot figure out is why this additional value adding to lambda and R/U values. What values should I use for interior walls? Interior meaning two conditioned spaces on either side of an insulated boundary. The wall style has a lambda value determined by components.
