[Bldg-sim] FW: HVACTempate autosizing error

[Michael J Witte]

It's asking for design environments, or design days.  In the examples, 
you should see some SizingPeriod:DesignDay objects.  You will need to 
add similar objects for your location.  If you are using one of the 
standard EnergyPlus weather file locations, there is a ddy file included 
with the epw weather that contains all of the standard ASHRAE design 
days in EnergyPlus format.  Just copy/paste the desired design days from 
the ddy to your idf.
