Hi,
Thanks for sharing this code. It is very helpful. I have been trying to understand the calculation mechanism by comparing it to an excel version of the ISO 13790 (EPC Calculator) code I have from when I was at Georgia Tech.
When trying to calibrate the two models, I am seeing major variations in the heating and pump outputs and was curious if you had come across this, or perhaps if the c++ is using slightly modified equations to get to the results. Any feedback would be helpful!

Thanks

Hi, Thank you for sharing your ISO modeling code with rest of us.

I once played around the OpenStudio's own ISO simulation code(runIso.rb,osm2ism.rb,...)

It seems they have stoped developing ISO related functions. So, I am going to switch to your simulator.
NREL/OpenStudio#2345

But, the ism file which I have transtrated from *.osm using original "osm2ism.rb" does not work with your isomodel_standalone simulation.

It seems there are two versions of *.ism. V1 is original ism format and v2 is the new one.
(SmallOffice_v1.ism, SmallOffice_v2.ism in the test_data are the examples)

I can manually modify v1 output to v2 by looking at the error code of isomodel_standalone.
Is this the only way to convert *.osm to *.ism for the time beeing?

Thank you for your effort.

This is more of a question than an issue: is it possible to define more than one zone/schedule in the ism input file?
