Condensation analisys

I am trying to calculate the probability of condensation in a building. I set up the energy model with latent loads and calculate the Surface Inside Temperature and the Zone Mean Air Dewpoint Temperature.
If the surface temperature is equal to the Zone Dewpoint temperature condensation may occur.
How can I take the two results (Surface Inside Temperature and Zone Mean Air Dewpoint Temperature) and compare them in grasshopper?
The Zone Dewpoint has 8760 data points and the Surface inside temperature has 8760 data point for each wall.
