Has anyone in the group used the sunspace option in eQUEST?  I have tried it and  it blew up in LOADS   Following is the .inp description of the Sunspace:

 

"EL1 North Perim Spc (G.N1)" = SPACE           

   X                = -25.25

   Y                = 109.6

   AZIMUTH          = 51.024

   SHAPE            = POLYGON

   ZONE-TYPE        = CONDITIONED

   PEOPLE-SCHEDULE  = "EL1 Bldg Occup Sch"

   LIGHTING-SCHEDUL = ( "EL1 Bldg InsLt Sch" )

   EQUIP-SCHEDULE   = ( "EL1 Bldg Misc Sch", "EL1 Bldg OffEq Sch", 

         "EL1 Bldg OffEq Sch" )

   INF-SCHEDULE     = "ZG1-S1 (UVT) P-Inf Sch"

   INF-METHOD       = AIR-CHANGE

   INF-FLOW/AREA    = 0.0563044

   PEOPLE-HG-LAT    = 217.268

   PEOPLE-HG-SENS   = 250

   LIGHTING-W/AREA  = ( 1.14175 )

   EQUIPMENT-W/AREA = ( 0, 0, 0.791 )

   SUNSPACE         = YES

   AREA/PERSON      = 165.463

   POLYGON          = "EL1 Space Polygon 1"

   C-SUB-SRC-BTUH   = ( 0, 0, 0 )

   C-SUB-SRC-KW     = ( 0, 0, 0 )

   C-ACTIVITY-DESC  = *Office (Executive/Private) (79%)*

   ..

"EL1 North Wall (G.N1.E1)" = EXTERIOR-WALL   

   CONSTRUCTION     = "EL1 EWall Construction"

   LOCATION         = SPACE-V4

   SHADING-SURFACE  = YES

   ..

"EL1 North Win (G.N1.E1.W1)" = WINDOW          

   GLASS-TYPE       = "EL1 Window Type #1 GT"

   FRAME-WIDTH      = 0.108333

   X                = 0.808333

   Y                = 0.938333

   HEIGHT           = 7.17333

   WIDTH            = 138.803

   FRAME-CONDUCT    = 1.306

   SPACER-TYPE      = INSULATED

   ..

"EL1 SW Wall (G.N1.I1)" = INTERIOR-WALL   

   NEXT-TO          = "EL1 WNW Perim Spc (G.WNW4)"

   CONSTRUCTION     = "Sunspace Wall construction"

   LOCATION         = SPACE-V1

   ..

"EL1 South Wall (G.N1.I2)" = INTERIOR-WALL   

   NEXT-TO          = "EL1 Core Spc (G.C5)"

   CONSTRUCTION     = "Sunspace Wall construction"

   INT-WALL-TYPE    = STANDARD

   LOCATION         = SPACE-V2

   ..

"Sunspace Window" = WINDOW          

   GLASS-TYPE       = "EL1 Window Type #1 GT"

   X                = 1

   Y                = 6.5

   HEIGHT           = 2

   WIDTH            = 122

   C-WELL-HEIGHT    = 6.5

   C-WELL-WIDTH     = 1

   ..

"EL1 SSE Wall (G.N1.I3)" = INTERIOR-WALL   

   NEXT-TO          = "EL1 SE Perim Spc (G.SE2)"

   CONSTRUCTION     = "Sunspace Wall construction"

   LOCATION         = SPACE-V3

   ..

"EL1 Ceiling (G.N1.I4)" = INTERIOR-WALL   

   NEXT-TO          = "EL1 North Perim Plnm (G.N6)"

   CONSTRUCTION     = "Air Ceiling of Sunspace"

   INT-WALL-TYPE    = AIR

   LOCATION         = TOP

   ..

"EL1 Flr (G.N1.U1)" = UNDERGROUND-WALL

   CONSTRUCTION     = "EL1 UFCons (G.N1.U2)"

   LOCATION         = BOTTOM

   ..

 

Following is the system description of the sunspace:

 

"EL1 North Perim Zn (G.N1)" = ZONE            

   TYPE             = CONDITIONED

   MIN-FLOW-RATIO   = 1

   BASEBOARD-RATING = -25605.4

   FLOW/AREA        = 0.25

   OA-FLOW/PER      = 18.2732

   SS-FLOW-T-SCH    = "Max T for SS heating Annual"

   SS-VENT-CST      = 5

   SS-VENT-WND      = 0.2

   SS-VENT-TEMP     = 0.2

   SS-VENT-T-SCH    = "Vent T Annual Schedule"

   SS-VENT-SCH      = "Sunspace Venting Schedule"

   DESIGN-HEAT-T    = 72

   HEAT-TEMP-SCH    = "S1 Sys1 (UVT) Heat Sch"

   DESIGN-COOL-T    = 75

   BASEBOARD-CTRL   = THERMOSTATIC

   SIZING-OPTION    = ADJUST-LOADS

   SPACE            = "EL1 North Perim Spc (G.N1)"

   ..

"EL1 North Perim Pl Zn (G.N6)" = ZONE            

   TYPE             = UNCONDITIONED

   DESIGN-HEAT-T    = 67

   DESIGN-COOL-T    = 75

   SIZING-OPTION    = ADJUST-LOADS

   SPACE            = "EL1 North Perim Plnm (G.N6)"

 

Following is the error message

 

***ERROR***********************************************************************

In routine TEMDEV for ZONE EL1 North Perim Pl Zn (G.N6)     on  2/10 hr 11 (InitialFlg =  0)

  SUNSPACE INTERIOR-WALL calculations produced bad values:

  CSSVEC (convection) =           0. CSSVEC (conduction) =     7294864.

  This would cause a  262. degree ZONE temperature change.   Values are being ignored.

  Check wall definitions for errors and report this inp/lib/wth to DOE-2 support.

 

***ERROR***********************************************************************

  This would cause a 6794. degree ZONE temperature change.   Values are being ignored.

  Check wall definitions for errors and report this inp/lib/wth to DOE-2 support.

 

Any ideas as to where I went wrong?
