Hello, I found questions similar to mine but unfortunatelly no useful answers yet.

Anyway, I am using Honeybee_Export to OpenStudio component for GH and I am doing a Loads Calculation. One of the outputs I want ti get is:

Zone Opaque Surface Outside Face Conduction

Following the instructions from the component, that the input should be a complete energyplus component, I inputed the following:


*, !- Key Value

Zone Opaque Surface Outside Face Conduction, !- Variable Name

timestep; !- Reporting Frequency

Is this the correct way to do it? if not, where can I find more guidelines on how to do it? (I already tried to find the answer in the energyplus 847 pages documentation)

So to answer a part of my question:

I would suggest first of all to check for the availability of the results you are searching for, for example I was looking for: Zone Opaque Surface Outside/Inside Face Conduction Gain without checking if the idf file I was producing was 'requesting' it from E+.

There is an easy solution to that: By plugging-in the rddfileAddress, from 'Honeybee_export to OpenStudio' to the 'Honeybee_Read Result Dictionary' You get to see what is available: image description

as you can see 15 outputs match my search, but not the one I want.


1) BigLadder

I know that I this output can be produced from E+

2) Unmet - previous post

I understood that I was missing something.

TL DR; Apparently E+ is not showing all the variables it is calculating, unless you ask. So to the additionalStrings_ input instead of adding the desired output you have to ask for the Advanced Report Variables.

as you can see 19 outputs match my search, this of course only solves half of my issue, since I need both the outside AND inside face conduction but it is better than nothing.

So if you have any suggestions, as to how I can figure out the rest, I would really appreciate it.
