May you help me to understand following warnings, please?

Link to the IDF file

----------

** Warning ** CheckEnvironmentSpecifications: SimulationControl specified doing design day simulations, but no design environments specified.
   **   ~~~   ** ...No design environment results produced. For these results, add appropriate SizingPeriod:* objects for your simulation.

----------

** Warning ** ManageSizing: For a zone sizing run, there must be at least 1 Sizing:Zone input object. SimulationControl Zone Sizing option ignored.

----------

 ** Warning ** ProcessScheduleInput: Schedule:Day:Interval="LARGE OFFICE CLGSETP DEFAULT SCHEDULE 1", Blank Schedule Type Limits Name input -- will not be validated.

----------

** Warning ** ProcessScheduleInput: Schedule:Compact="HVACTEMPLATE-ALWAYS 4", Blank Schedule Type Limits Name input -- will not be validated.

Attach the IDF please

Also, specify how you originally created it.

@Antop, I moved your IDF file to Pastebin.com so that people can link to it. In general, please do not use the "Answer" section below to respond to comments. Thanks!

Each warning above references a specific EnergyPlus object type, e.g. SimulationControl. The Input Output Reference for that object type should give you enough information to better understand the warning. For these particular warnings:

You've requested that sizing periods be simulated, but there are no sizing periods in the file. Can be ignored.
You've turned on the zone sizing calculation, but there are no sizing objects present. Can be ignored.
You've omitted the schedule type in some schedule objects, so they will not be validated. Can be ignored.

I read the following warning message

* Warning * GetSimpleAirModelInputs: ZoneInfiltration:DesignFlowRate="THERMAL ZONE 5 189.1-2009 - OFFICE - WHOLEBUILDING - LG OFFICE - CZ1-3 INFILTRATION 2", Design Flow Rate Calculation Method specifies Flow per Exterior Surface Area, but Exterior Surface Area = 0. 0 Infiltration will result

Within my model , "the thermal zone 5" is a central zone image description

obviously, I have not "exterior surface area", so I don't know how I can have infiltration. what do you suggest me?

Antop ( 10 years ago )

@Antop One could argue that zero infiltration is valid for a core zone, but if you want to include some, then you need to select a different Design Flow Rate Calculation Method such as flow/zone, flow/area, or AirChanges/Hour. (Also, I would suggest that you change this comment to be a new question.)
