I am trying to set the SHGC(Solar Heat Gain Coefficient) in OpenStudio for a Fixed Window under the category Simple Glazing System Window Materials using a ruby measure. I am using OpenStudio 1.6.0 and there is no method to set the SHGC using ruby that I can find. The only other way I have found to set SHGC is by translating the whole model to EnergyPlus, setting SHGC and bring it back to OpenStudio. The code for that method looks like this:

ft = OpenStudio::EnergyPlus::ForwardTranslator.new
workspace = ft.translateModel(model)
win = model.getObjectsByType("WindowMaterial:SimpleGlazingSystem".to_IddObjectType)
win[0].setDouble(2,shgc) 
bt = OpenStudio::EnergyPlus::ReverseTranslator.new
model = bt.translateWorkspace(workspace)

Unfortunately the above code seems to work in the cmd but the changes do not show up in OpenStudio. What should I try next to set the SHGC?

We use version 2.4.0. You believe there is a bug in this version of OpenStudio?

Hi, Our error here doesn't appear to be in measures - when a local server was run, all the measures ran without errors.

I have been trying to setup the OpenStudio residential workflow and am getting stuck on the final measure - HVAC Sizing. I setup the workflow as defined here: https://github.com/NREL/OpenStudio-BE... in PAT. The error I am getting states that:

"undefined method -' for nil:NilClass\n\tC:/AWS/Residential WorkFlow/temp_data/analysis_bfc74e65-b296-449b-9651-c706bc039376/measures/ResidentialHVACSizing/resources/geometry.rb:362:inget_height_of_spaces'

I dug deeper into it and it appears that none of the spaces are showing up as conditioned, so no height is populated meaning the system can't be properly sized. Has anyone run into this issue before or had issues with the HVAC sizing measure when trying to run the whole residential workflow?

This is perfect for right now. Thanks!

I ran analysis with 1600 models using PATs algorithmic mode in LHS. The results CSV was populated properly but when I tried to download all the OSMs(by pressing the OSM cloud download button), PAT only downloaded 200. It appears to only be downloading the ones shown on the main PAT page but I want to download all of them. Is there an easy way to do this? I looked at the Server but it appeared to only let you download one at a time to. Thanks for the help!

Thanks, the issue lay in the non unique values for my second variable. It runs fine now.

I am trying to run ~2000 models through PAT. I have set it up using the Algorithmic method DOE and it works for small batches(~50 models), but fails at anything larger. I have the server and worker setup to be c3.8xlarge giving me plently of cores for the simulations. The issue is it just doesn't seem to que up the runs when there are greater than 50 design alternatives. What can I do to fix this? Below are the two error messages I found in the logs:

Error 1:

/opt/openstudio/server/lib/analysis_library/doe.rb failed with voidEval failed: Packet[cmd=2130771970,len=<nil>, con='<nil>', status=error:'Unknown variable/method'(127)]

Error 2:

Error in contr.poly(nlevels[i], scores = factor.names[[i]]) :

Same issue with the new version, any ideas?

I'm just starting to use PAT 2.0 after using the OpenStudio analysis spreadsheet in the past. The one function I am looking for in PAT from the spreadsheet and cannot find is the Parallel Batch Running. What I am trying to do is run a series of unique scenarios (so something like the full_factorial analysis doesn't work) from a list created in Excel. Is there a way to do this in PAT 2.0?

I'm running different design alternatives in PAT and gotten output results using the OpenStudio Report measure. Is there a summary reporting measure that will compile all the Design Alternative results into one table? For example it would be useful to have all the end uses consumption for each design alternative in a summary table. Is this possible? And if so is it possible to get it in CSV format?
