[EnergyPlus_Support] Surrounding grounds

["alexandrevarela2000" <amv@xxxxxxxxxxxxxxxxxxxxx>]

Dear all:

I'm starting my E+ exploits and I have come across one (among many) 
question:

As far as I know, the only parameter I can change for the  ground is 
temperature and reflectance.So if I want to simulate external grounds 
as concrete or grass I can only change reflectance. This leads to 
misleading results sincenot only reflectance is different. 
Absorptance and emissivity change as well an these take an important 
role in radiative heat transfer.

Is it possible to simulate this situation? My guess is that maybe I 
just have to add another heat transfer surface, something like 
a "floor" surrounding the building perimeter.

Thank you all for your help, best regards from Portugal,
Alexandre
