Apologies if this topic has already been covered;
I am in the midst of detailing the EP construction of the surfaces in a project, with the intention of making the results as accurate as possible I am using the Honeybee_EnergyPlus Opaque material component to create an EP material for the tentative insulation being used.
My question is in regards to the input for thermAbsp (Thermal absorptance)
once again apologies; my only degree is from google and youtube universities: If I am not mistaken the input param being requested is for the emissivity, is this asking for Hemispherical (ε), Spectral Hemispherical (ε/ν or ε/λ) or directional emissivity ε/Ω?
@MingboPeng You laid the groundwork for PassiveBee perhaps you can shed light on the matter?
I am transcribing the construction from WUFI passive and said material properties if I am not mistaken are not referenced. once I get a handle on deriving the input param from other material data that is available I will most definitely make a component to handle the calculations and share!
WUFI material properties for reference:
