error simulation

edit

I am PhD student, I use design builder program to study indoor thermal comfort, the case study file which I modeled wasn't simulate completely, and there were error message, I need to know what are the right steps to can fix this file. the error massage : rogram Version,EnergyPlus, Version 8.9.0-40101eaafd, YMD=2020.12.27 16:55, * Warning * ManageSizing: For a zone sizing run, there must be at least 1 Sizing:Zone input object. SimulationControl Zone Sizing option ignored. * Warning * Site:GroundTemperature:BuildingSurface: Some values fall outside the range of 15-25C. * ~~~ * These values may be inappropriate. Please consult the Input Output Reference for more details. * Warning * CalcSurfaceCentroid: 8 Surfaces have the Z coordinate < 0. * ~~~ * ...in any calculations, Wind Speed will be 0.0 for these surfaces. * ~~~ * ...in any calculations, Outside temperatures will be the outside temperature + 9.750E-003 for these surfaces. * ~~~ * ...that is, these surfaces will have conditions as though at ground level. * Warning * GetSurfaceData: There are 9 window/glass door(s) that may cause inaccurate shadowing due to Solar Distribution. * ~~~ * For explicit details on each window, use Output:Diagnostics,DisplayExtraWarnings; * Warning * CalculateZoneVolume: 5 zones are not fully enclosed. For more details use: Output:Diagnostics,DisplayExtrawarnings; * Warning * CheckUsedConstructions: There are 5 nominally unused constructions in input. * ~~~ * For explicit details on each unused construction, use Output:Diagnostics,DisplayExtraWarnings; * Warning * DeterminePolygonOverlap: Too many figures [>15000] detected in an overlap calculation.

*** ===== Final Error Summary ===== *** The following error categories occurred. Consider correcting or noting. *** Nominally Unused Constructions *** ..The nominally unused constructions warning is provided to alert you to potential conditions that can cause *** ..extra time during simulation. Each construction is calculated by the algorithm indicated in the HeatBalanceAlgorithm *** ..object. You may remove the constructions indicated (when you use the DisplayExtraWarnings option).
