Re: [EnergyPlus_Support] SIMULATING FLOOR

["Edward Lyon" <eglyon@xxxxxxx>]

I didn't switch to MOIST 3.0 because of the inability to control "inside" conditions directly.  I used MOIST 2.1 because it has a special provision for using test data input files.  If you have a copy of MOIST 2.1, run a dummy calculation of your model and save the boundary conditions output file.  Use the calculated sol-air temperature as an exterior temperature and generate your own interior conditions.  Make new input RH based on the sol-air temperature.  Run the model again with the special input file.

However, HEAT 2 (couple of hundred dollars) allows you to place heat generating elements in the model.  I'm not sure if there is a utility to read weather files for input data.

I read Mike's reply and EnergyPlus could work as long as you describe "room" for conditions to be calculated on.  However, consider that the calculating engine is designed to calculate the air conditions and interactions with surroundings and not necessarily the temperatures through the layers of those surroundings.

Final thought, if the surface sees snow, you are into another layer of complexity.  Snow melt systems are designed for heat output to melt snow, not maintaining surface temperature above freezing.  You may need to build a more sophisticated calculation to model what you are doing....
