i'm using the " Set Exterior Roof Assembly to User Input U Value" measure and for some reason it doesn't seem to work and i keep getting the same results no matter what value i input as a U-value for the exterior roof in my model ? Osm Model Regards
As I said above, adding a direct link to the measure on the BCL would be helpful. In this case, it's critical: there are actually two measures with the same name, and one of them has an error.
This measure checks if the surface is a Wall instead of a RoofCeiling: https://bcl.nrel.gov/node/82299
This measure checks if the surface is a RoofCeiling: https://bcl.nrel.gov/node/82298 and had a problem before
The line in question is L154:
if surface.outsideBoundaryCondition == "Outdoors" and surface.surfaceType == "Wall"
Initially this problem has been reported by Matt Steen on Github and corrected by David Goldwasser as highlighted here: https://github.com/NREL/OpenStudio/is.... This is the first thing that pops up when you google the name of the measure.
thank you for your reply but the problem is yet unsolved. i keep getting errors whenever i apply the measure Osm Measure
Open the error log itself (stout and stderr likely). See http://nrel.github.io/OpenStudio-user...
thank you for your reply, here is the error log if i remove the measure, the model works just fine. here is my osm model
Is there anything that looks useful for us when you open the stdout and stderr?
no, i don't think it has something that's important that's why i haven't added it essentially to my post but you asked for it so i did. i personally have no clue why it's not working, when i use it with a wall instead of a roof on the set value for roof part the simulation has no errors yet no change to the energy usage but when i use it with a roof i get an error right away
