Re: [EnergyPlus_Support] Annual Peak cooling variable ?

[Jeremiah Crossett <jcrossett@xxxxxxxxxxxxxxx>]

Li, Don't take this the wrong way- as I have eminence respect for your advise to me and others-- You do not have to be right all the time- and should make a point to fully understand the problem before you speak down at people for actual real world issues that you do apparently not understand.
RE: The hourly average value is not useful to determine smallest system size- if an option was added to the idd and accessible from idf editor to output Min or Max than the problem would be solved and it would be useful for minimizing peak loads when performing  parametric/iterative simulations. Yes a script could also solve the same issue, but then every user would have to re-do the same work over and over- so it makes more since for the developers to add the functionality.

The goal of the study is to optimize the envelope to minimize cooling load so that it is close to or below this value.
