2020-07-12 22:40:07 -0500 | marked best answer | Boiling hot temperatures in prototype model of small hotel 90.1-2013 Hi all, I've been working with the 90.1-2013 protoype model of a small hotel, in climate zone ASHRAE 169-2013-5A. When running a simulation without any further modifications (using an Amsterdam weather file), I'm getting some very questionable results. The elevator core at the ground floor has temperatue variations between 40 and 95 degrees Celcius (105 - 205 Fahrenheit). The neighboring rooms are of course affected. Particularly the laundry room next door, with similar but delayed and slightly attenuated temperatures. I believe such temperatures would be bad for business. Here is a screenshot of all air thermal zone temperatures: From top to bottom, the lines represent:
Outside temperature is close to freezing. I'm using the most recent versions of OpenStudio and EnergyPlus. Clearly something is quite wrong, which surprises me from a protoype model. Any advice on how I can track down and solve the issue? In the meantime, I'll keep investigating and will update if I find anything. Thanks! |

2020-06-29 21:06:22 -0500 | marked best answer | Cannot run an OS simulation with External:File schedule Hi all, I am trying to assign occupancy schedules to spaces with some Ruby code, taking inspiration from various posts and links here, amongst which these: - https://unmethours.com/question/36508... - https://unmethours.com/question/21623... - https://github.com/NREL/OpenStudio-re... Problem: I have succeeded attaching a schedule from a csv file, but I cannot seem to get a simulation to run with it. I have written a small script that opens an existing osm model, loads a csv schedule file, assigns it to a space and saves the resulting model to a new file. Note, it is not written as a measure, just as a separate script taking a file, altering it and saving it: (the osload and save_openstudio_osm functions are borrowed from the second and third links above) So far, so good. The new file 'adjusted.osm' is created. However, I cannot get it to simulate when loading it into the OpenStudio application. (the original file small_hotel.osm runs without issue). The error: **FATAL:Errors occurred on processing input file. Preceding condition(s) cause termination. Inspection of eplusout.err shows: Last severe error=<root>[Schedule:File][Schedule File 1] - Missing required property 'file_name'. The adjusted.osm file has the following on the external file: I think that the file 'occupance.csv' is not found, but I don't know how to solve this. I have tried replacing it with an absolute path, but that also does not work. Moving it to the same location as the weatherfile also doesn't help. Would anyone know how to resolve this? |

2020-06-26 04:16:23 -0500 | marked best answer | PAT fails as soon as I add the OpenStudio Results Measure I'm running PAT and am trying to include the OpenStudio Reporting measure. However, every run will fail as soon as I assign the reporting measure. Without it, everything runs fine. I think (but I'm not exactly sure) that I didn't have this problem a few days ago. A new version of the OpenStudio Results reporting measure came out 1-2 days ago. Not sure is that is related? The failure gives no output at all. Status is Completed Fail, without listing any warnings or errors. The log files are likewise empty. Further debugging is impossible (or at least, I don't know how), since no results are generated with the reporting measure, as that is actually what seems to be causing the problem. Any help would be much appreciated. Thank you in advance. Update 1: the final OSW for one of the failed runs: No warnings or errors... Update 2: Running the model in OpenStudio (v1.0.0), using only the OpenStudio reporting measure fails (for message see comment below). The run.log file shows the following trace: [09:45:59.636175 ERROR] undefined method |
