Anyone have any advice on modeling phase change materials in Energy Pro, or
any other SIM software/workarounds to work in any other SIM software? I
have projects in CA so Energy Pro would be nice..

My problem is Energy Plus is showing the same results when changing the
enthalpy temperature input as stated bellow...

I am working on modeling phase change materials in Energy Plus, Here is
an example what I am working on creating output visualization (once I get
the modeling figured out)

I ran an experiment with the generic data from the example phase change
materials IDF, as well as four varieties of data configuration and bench
marked them against an identical building with no phase change materials
and was very disturbed at the results.

All buildings with phase change use exactly the same amount of energy!
It makes me wonder if the phase change calculations are not really using
the input data, as the energy is the same kBtu for each.. Below is the
graph and here are links to my analysis sheets..

The results piloted below

Any help or advise would be great, as I want to compare phase change
products, brands and technologies but if the enthalpy temperature data does
not change the outcome then that seems impossible.
