Question 1 - Output/Results

  • In an attempt to get the peak cooling and heating load, which aren't readily available in OpenStudio Results measure under the Output tab, I added additional variables from e+ .rdd file "zone list sensible cooling rate" and "zone list sensible cooling rate" with the frequency set at "runperiod".
  • I used "AddOutputVariable". In the output tab, I don't see the variable in "select outputs" after adding the "AddOutputVariable" measure. So I manually entered the variable name and don't know if PAT really recognizes it or not.
  • These are hourly variables but I was testing if it can give me one peak value of the entire runperiod of 8760hrs
  • Also, how do I add outputs in "OpenStudio Results"? Simply copy-pasting the variable name from .rdd didn't work

Question 2 - Run/model files for all alternatives

  • Is there a way to download all the generated zip files for alternatives from the OpenStudio Console on AWS at the same time. Or do I have to download them one by one?

Thanks in advance!

In the future, please create two threads, one for each separate question, so it's easier to maintain, answer, and search for.

For Question 1, the AddOutputVariable just adds time series data to the EnergyPlus SQL file, it doesn't alter the OpenStudio Results html file. You can use Dview to to inspect the time series data or you can write a custom reporting measure to inspect that data and report the maximum value.

In this case however you may be able to lean on the HVAC Sizing Summary in the EnergyPus HTML file that comes with the simulation.It has a Zone Sensible Cooling and Zone Sensible Heating table.

In the future, please try and break each question into its own post, but in this case there is an existing post with that question and answer that you can refer to.
