Hi all,

I am working on a HVAC project where many components(cooling coils, pumps, etc) needs to be modelled newly(new equations), and in addition new hydraulic connections. And EnergyPlus needs to be used for the overall system level simulation. For that I have to write/include the new equations into EnergyPlus. I have heard that the codes in EnergyPlus are written in C++. Problem is I haven't been able to begin with a good start. Primarily- Where do I go to edit/add new codes? , and how do I create new Hydraulic connections between components? If you could point me to a direction, that would be hugely beneficial.

@Asutosh_Boro_TUe if you search for questions with the tags "energyplus" and "source-code", you should find ~30 posts that have asked similar questions. In summary -- modifying EnergyPlus source code is rather difficult, and it also requires building a custom EnergyPlus executable file for simulations from your modified source code.

Does that answer your question?
