I'm using openstudio 1.10.0., and during the simulation I have in my screen the following image description.

My location is not chicago, and I imported a.ddy file from my location. What this means? It will affect my simulation? It's a bug?

The program is showing you the name of the Sizing:Period object specified in your input file. This is only a unique name, however, I suspect that other inputs in this object are specific to Chicago and should be reviewed and modified as needed. For example, what is the maximum dry-bulb temperature for your location during the specified day in the Sizing:Period object? Does this match the value specified here? There are also other values in this object that should be reviewed.
