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!

Sorry for the delay in responding. There have been a couple changes in some parts to correct for some bugs in the spreadsheet as well as to adhere better to the ISO standard. The spreadsheet mixes stuff from ISO with some other standards. Also, we had an update to the pump code directly from Fried's group that might not be in the spreadsheet you have. Why don't you contact me directly via email ([email protected]) and send me your spreadsheet so we can try to resolve the differences.
