[EnergyPlus_Support] Re: Emissivity in Material

["malindo_wardana" <fypguevibyor@xxxxxxxxx>]

Hi Linda,

What you mean is absorptance is equal to emissivity right?
If that's the case then there are Thermal Absorptance and Solar Absorptance. Thermal Absorptance is for "long wavelength" and Solar Absorptance is for visible, infrared and part of UV. I am not so clear whether "long wavelength" includes the solar spectrum (visible, infrared and part of UV) or not.

Could you advise me about this?
