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. * ~~~ * any calculations, Wind Speed will be 0.0 for these surfaces. * ~~~ * 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. Use Output:Diagnostics,DisplayExtraWarnings; for more details. * Warning * Output:Meter: invalid Key Name="GAS:FACILITY" - not found. * Warning * Output:Meter: invalid Key Name="GAS:FACILITY" - not found. *** Testing Individual Branch Integrity *** All Branches passed integrity testing *** Testing Individual Supply Air Path Integrity *** All Supply Air Paths passed integrity testing *** Testing Individual Return Air Path Integrity *** All Return Air Paths passed integrity testing *** No node connection errors were found. *** Beginning Simulation * Severe * PsyRhoAirFnPbTdbW: RhoAir (Density of Air) is calculated <= 0 [-3.26553]. * ~~~ * pb =[100920.00], tdb=[-379.81], w=[5.9506811E-003]. * ~~~ * Routine=CorrectZoneHumRat, During Warmup, Environment=UNTITLED (28-O5:28-O5), at Simulation time=05/28 08:15 - 08:30 * Fatal * Program terminates due to preceding condition. ...Summary of Errors that led to program termination: ..... Reference severe error count=1 ..... Last severe error=PsyRhoAirFnPbTdbW: RhoAir (Density of Air) is calculated <= 0 [-3.26553].

*** ===== 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).

*** EnergyPlus Warmup Error Summary. During Warmup: 0 Warning; 1 Severe Errors. *** EnergyPlus Sizing Error Summary. During Sizing: 1 Warning; 0 Severe Errors. *** EnergyPlus Terminated--Fatal Error Detected. 17 Warning; 1 Severe Errors; Elapsed Time=00hr 00min 10.51sec
