So, I'd like to develop two measures.
One should identify among all the plant loops in my model the chilled water loop and change for it the design loop exit temperature and the design loop temperature difference. I believe I have to get from the PlantLoop level to the Sizing:Plant level somehow to do that - something to the effect of "select from all plant loops the plant loop with name "CHW", then pick for that plant loop the sizing "bit" and adjust the exit temperature and temperature difference for that bit.
The other should identify all the chillers in the chilled water loop (CHW) and change for them the reference COP and the three EIR curves, based on data pulled from the same library as that for the add_chiller measure (I believe I have to add these curves somehow but might be able to reuse the corresponding part of the add_chiller measure for that). Unlike the add_chiller measure, I do not want to add chillers, but simply replace the above information for the existing chillers (and thus also just somehow reassign the curves, not add them together with a new chiller).
I have looked through the SDK documentation but unfortunately, it is much too convoluted for my linear mind to find the necessary entry points. However, I have modified other measures in the past and think I have at least a shot at what I want to accomplish as long as someone can set me on the right track.
