Currently working on a project and trying to find historical maximum surface temperature on a facade. I use Ladybug to find solar radiation value for given date and time. I then switch to CFD and apply “heat flux” boundary condition in [W/m2]. Numerical value being solar radiation from Ladybug, times emissivity of material.
QUESTION: is resulting radiation value from Ladybug directly translatable into “Heat Flux” for CFD models? In other words, is the result from Ladybug basically just heat?
I tend to think that Ladybug’s radiation result includes integrated energy of complete sunlight spectrum, while I’m interested only in that part, that generates heat = IR part of spectrum. If that’s right, I should be able to factor Ladybug’s radiation result down by more than just emissivity of material, before I go and apply [W/m2] as boundary condition to a CFD model.
What are your thoughts? Thank you all!
