Can't run simulation with model made with new WWR method #897

Closed DavidGoldwasser closed 10 years ago

DavidGoldwasser commented 10 years ago

I'll attach model, but here are the errors I see. I do have a default construction for interior partitions, but that appears not to work for the light shelf. Should the method allow a hard assign construction for light shelf and shading surface?

* Severe * DaylightingDevice:Shelf = DAYLIGHTING DEVICE SHELF 18: Inside shelf DAYLIGHTING DEVICE SHELF 18 must be its own Outside Boundary Condition Object. * Severe * DaylightingDevice:Shelf = DAYLIGHTING DEVICE SHELF 18: Outside shelf requires an outside shelf construction to be specified.

@DavidGoldwasser can you make a pivotal bug and put this at the top of my back log? ill try to get to this tonight

@macumber just made the pivotal story, and also pushed the model up. https://github.com/NREL/OpenStudio-files/tree/master/Git%20Issue%20Files/Issue897

I removed the view glass shading surface from the daylight shelf as EnergyPlus doesn't like this and it isn't really correct anyway. We can add a future option to add the exterior shading at the daylight window, then that could be part of the light shelf.

DavidGoldwasser commented 10 years ago

@macumber Will that address this error as well?

* Severe * DaylightingDevice:Shelf = DAYLIGHTING DEVICE SHELF 18: Inside shelf DAYLIGHTING DEVICE SHELF 18 must be its own Outside Boundary Condition Object.

macumber commented 10 years ago

@DavidGoldwasser yes it will fix that too
