[EnergyPlus_Support] Re: Error message

["JV Dirkes II" <jvd2pe@xxxxxxx>]

Dear Mr. Sundaram,

The messages are from E+.

The first message is just letting you know that E+ is more accurate
when using at least 4 timesteps per hour.
I think DesignBuilder has used a multiplier for identical windows. 
This is perfectly legitimate, but may cause slight inaccuracies for
shading calculations,  thus the message.

Neither message is serious.  Both situations can be edited / changed.
