Surface emissivity in mean radiant temeperature calculation of Microclimate Map Analysis

Yes, that’s exactly what I meant, I am sorry if my question was not clear enough. Thank you!!
I would like to test the effect on different material properties (including low emissivity ones, like metal and glazing) on outdoor Tmrt.
The formulation I would like to use to calculate the longwave Tmrt is the fourth root of the numerator of the formulation you quoted, like this (the third formula):

Do you think there is any way to do it in Honeybee? Like “extracting” surface emissivity values from energyplus and using them in the Tmrt formulation

Thank you!
