Simulating DaylightingDeviceShelf.idf from the Energyplus 9.0 Examples Files, with an Output:Diagnostics,DisplayExtrawarnings object added, creates a warning

* Warning * CalculateZoneVolume: The Zone="DAYLIT ZONE" is not fully enclosed. To be fully enclosed, each edge of a surface must also be an edge on one other surface.

The Warning continues saying the zone volume calculation is done by

* ~~~ * The zone volume was calculated using the floor area times ceiling height method where the floor and ceiling are the same except for the z-coordinates.

Granted, the proper way to specify a light shelf is energyplus is unusual, but it shouldn't create this warning.


What I really care about though is if this will or will not output accurate results. Is there any way to find out?
