[EnergyPlus_Support] Annual Peak cooling variable ?

[Jeremiah Crossett <jcrossett@xxxxxxxxxxxxxxx>]

Hello,

I have a parametric study of 1020 simulation "jobs" and with the objective function of minimizing peak cooling load.  I have experimented with the bullet pointed output variables below but all have provided average numbers rather then maximum. I have read the documentation and checked old posts but do not see any way to output to a variable or meter the annual maximum sensible cooling load. Does anyone have a solution for this? I seem to remember there being a way to create custom output values, but did not find anything in documentation.  I would think the peak cooling load would be useful for modelers/designers to be able to run many iterations to solve the lowest equipment size problem and am surprised that there is not an easy to do this- Possibly there should be a new feature added to Energy Plus that is for reporting called "maximum" ("minimum" would also do just fine, but "average" is not very useful for this) 

• Output:Variable,*,Zone/Sys Sensible Cooling Rate, !- HVAC Average [W]
• Output:Variable,*,Zone/Sys Sensible Load Predicted, !- HVAC Average [W]
• Output:Variable,*,Ideal Loads Heat Recovery Sensible Cooling Rate, !- HVAC Average [W]
• Output:Variable,*,Ideal Loads Total Cooling Rate, !- HVAC Average [W]
• Output:Variable,*,Ideal Loads Zone Total Cooling Rate, !- HVAC Average [W]
• Output:Variable,*,Ideal Loads Zone Sensible Cooling Rate, !- HVAC Average [W]
• Output:Variable,*,Total HVAC Electric Demand, !- HVAC Average [W]
• Output:Variable,*,Total Building Electric Demand, !- HVAC Average [W]
• Output:Variable,*,Total Electric Demand, !- HVAC Average [W]
• Output:Variable,*,Zone Total Internal Total Heat Gain Rate, !- Zone Average [W]
• Output:Variable,*,Zone Air Balance Air Energy Storage Rate, !- HVAC Average [W]

Attached is a results file with the issue of average not correlating to peak (minimum peak is in green)
