I am trying to include the abovementioned measure in my simulation. After starting the simulation, it stucks by following error: Error: No windows found in selection matching given construction. This means your model lacks windows or lacks windows with the specified construction.

I defined an operable window construction. But still doesnt work. Whats probably wrong with the window definition?`

Best, Martin

I recently updated this measure. Changelog on Github here.

The measure looks through all your fenestration objects, selects ones that match the construction you specify, and then makes an add wind stack object for each one. The issue you are facing is likely that there aren't any windows in your model with the construction you selected in the measure arguments. Make sure that you aren't overriding your window constructions elsewhere in your model; there are many places to specify constructions in OpenStudio. If you go to the spaces -> subsurfaces tab, you can see which construction is being applied to your windows.

To add to this answer, I've noticed I have to manually go to spaces --> subsurfaces, then press save in order to get the measure to recognize the window construction. So even if you have your subsurfaces specified correctly you may have to do this. Took me a while to figure this out so hopefully this helps others in the future who may experience this issue.

is there any way to check the openign area that the meassure is using. My understanding is that the measure takes the fenestration objects than match the construction specified and calculates the area. Then it multiplies that area for the open area fraction schedule (50%).

Can I draw in the same wall two windows. One operable and the other fixed then select windows construction int he measure to add wind and stack open area only to the windows defined as operable?

How i can change the faction of open area (50%) to an other value?

Thanks

@obuchely you could edit the measure to only apply to windows of a certain construction

I am getting the same error using OpenStudio1.3.0, ie "No windows found in selection matching given construction. This means your model lacks windows or lacks windows with the specified construction". This happens on opening the measure so the run goes no further, so there is just an "in.osm" file. I have double-checked that the constructions are correct, changed to BCL windows, selected and deselected the construction option in the measure - otherwise default values. All to no effect. Does anyone have any suggestions? It runs perfectly well without the measure.
