Hi all,
I'm using the basement preprocessor to model the ground heat transfer for an existing small building in Energy plus. On the input parameters, I have to input Indoor temperature every month, so that the preprocessor can estimate the heat flux.
How shall I obtain those indoor temperatures?
I have tried running the model with two sets of monthly mean air indoor temperatures: 1) Obtained from a preliminary run considering the surfaces in contact with the ground as adiabatic. 2) Obtained from a preliminary run considering a simplified ground temp of 18ºC
I am comparing the resulting zone temperatures of the simulation with temperature recordings we made in the building (unheated), but none of the options seems to get close enough to give us confidence. One option shows consistent 3-4K above, the other is some 3K below.
I've checked E+ documentation and the Ground heat transfer manuals but it didn't clarify this. Thanks, Rafael
