Hi everyone, I am going to optimize the best type of CHP(exp. GSHP, District heating, and electric heating system) with the lowest price using EnergyPlus and jEPlus+EA.I investigated EnergyPlus examples and noticed that there should be some changes in every HVAC options and variables(if I quite got the point). I was wondering if it would be possible to change the CHP type just by one variable? How could I optimize the CHP?
