How to calculate outdoor Mean Radiant Temperature using Ladybug/Honeybee

[gonchotorena]

Hello community, I resurrect this question because I see some strange results.

I wanted to calculate the Mean Radiant temperature for outdoor using Honeybee, I mean, the effect of grass and concrete pavement on the air, I take the example of this post:

Thanks for the information and the references. Im gonna check the problems, but its probably I will use the official epw files. I´m new with ladybug, when you say tickness of the ground zone you refer the distance of the extrusión of the geometry, isnt i? As well the thick of the soil is the material, in your example 1m. Is it correct? Thank you for you help, and Im go on investigating.

And I see some strange results:

1. If I use Export to Openstudio Battery for calculations with thermal_absorptance on grass 0.6 : The air temperature is reversed, the air over grass is warmer but the surfaces are ok:

2. If I use Run Energyplus Battery, I cant use thermal_absorptance less than 0.81. It says:
   The simulation has not run correctly because of this severe error:
   ** Severe ** [Material:RoofVegetation][GREENROOF][thermal_absorptance] - “0.600000” - Expected number greater than 0.800000

3. So, If I increase the thermal absorptance to 0.81 this is the result: Surfaces ok but there are no differences in the air temperature
   

   

4. And, If I use again export to openstudio, with thermal absorptance to 0.81, the results on surfaces and air is different than Eplus.
   

   

I attach the grasshopperfile with the point 4 setting
