Again, Did you look at CSVProc -- one of the many statistics is for MAX or MIN.
I have not personally used it recently. It implies it should be hourly but perhaps TimeStep/detailed would work as well.
We can also give you the source code. (I believe it is in Fortran but is a pretty simple program).

Linda+Brent, Thank you for your response and for understanding the issue. I suppose I could run the parametric and optimization with the sensible cooling rate checked and plan to create a script that can get the data from the .eio or ,html.. it is surprising that there is not a way to do this currently within E+ such as the use of a readvarseso with a .rvi file, or better yet a min/max reporting option. This would be useful for discovery of peak load reduction strategies. How does one request a new feature to be added to the tax dollar funded E+ project ?>Is there a formal way to do this?
Adbou, Thank you but No, you will get the average number rather then the peak by clicking on spreadsheets button- if you read the post I want to get the maximum sensible cooling rate so I can plot a cart of many simulations at once. The average number does not indicate the design with the smallest cooling system size. I am doing this so that I can do smaller parametric runs on my PC of about 1000 simulations and larger optimisation runs on a university super computer. The goal is again to have a variable that shows peak cooling load. The information is available in the .eio file, but readvarseso can not get the info to write a csv file with.

- Brent, thanks again for your help and sorry I did not understand your suggestion, but now understand that the number is in the eso file but do not understand how to get it to csv.
- Linda, or Brent I found the max value but am not sure how to "tell' readvarseso to write this to CSV? Would you have any advise> ? Could I for instance out he word "Max" after the output variable name in a .RVI file? Because this is for a large set of output it would be great if there was some way to do this with .RVI or MVI.
- (So would such syntax as "Sensible Cooling Rate Max" work?) The issue is that I need to have single values so that thousands of runs can be compared to each other at one time such as in this spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0Ag7cD5ZV9QwRdFgyWjJXN3IyTVduc2VrcXRlLU95ZlE
- So from the eso file I have the following values:
- Average value is 368.89[W]
- Peak value is 1160.83[W] the date of August 21st Minute 16 minutes 53 seconds,
- Minimum value is 7.74[W] the date of August 21st Minute 6 minutes 60 seconds.
