Does HB Energy account for the long-wave thermal radiation emitted toward the indoor space after the shading device is heated by solar exposure?

Hello everyone,

I have a question regarding how shading devices are treated in HB Energy simulations, particularly in terms of their thermal effects.

When simulating building energy performance with shading, does HB Energy account for the long-wave thermal radiation emitted toward the indoor space after the shading device is heated by solar exposure?

Related to this, in HB Energy, HB Shade and HB Louver Shades. Are these two types of shading treated as the same category in EnergyPlus, and do they follow the same physical modeling pathway?

I noticed that HB Louver Shades includes an indoor_ option, while HB Shade does not, which made me wonder whether they represent fundamentally different physical assumptions.

I would really appreciate any clarification or references to relevant documentation.
Thank you very much for your help.

Best regards,
Alice

Are HB Louver Shades, HB Window Material Blind, and HB Shade modeled using the same physical pathway in HB Energy?

I think the best way to learn this is to play with these components and see how it afects the IDF and learn how it works using EnergyPlus documentation. You can also compare results and see the effect and in which output!
