Yes... SO I am doing a Floor radiant Cooling system.

Zone Radiant HVAC Cooling rate would be the capacity of Radiant Cooling system....

How to validate that Zone Radiant HVAC Cooling rate?

Floor Net thermal radiation

Floor storage heat

Floor received short Wave radiation (both lights & Solar)

Floor Received LW radiation

Floor Convective part

anything else should I include to get values equal to that of Zone Radiant HVAC Cooling rate?
