We don’t consider ReadVarsESO to be “within E+.” It is just a small postprocessing aid that is included in the distribution. ESO (not EIO) stands for EnergyPlus Standard Output and it has had this data since version 1.0.
The formal way to make a request for a new feature is to post it to the helpdesk. The E+ team will then add it to the wish list.

Subject: Re: [EnergyPlus_Support] Re: Annual Peak cooling variable ?
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.
