[EnergyPlus_Support] Doubts

[arone lira <arone_lira@xxxxxxxxxxxx>]

Dear,



I?m trying to do a thermal loading simulation for an office room in a commercial building and I?m having some difficulties: 

The Office room has just one zone, with 3 interior standard walls and one glazed exterior wall. The propose is to analyze the thermal loading from the glazed exterior wall.



1st doubt ? How must be declared the Material of the exterior surface seen that the exterior surface is a wall completely glazed. When I declared the material in ?Material: WindowGlass? and modeled the surface type wall with a material of windows the EnergyPlus presentes a Severe Error. 

2nd doubt ? The 3 interior walls are beside of another similar room conditioned by the same HVAC, so there isn?t heat transfer between them. How can I declare it? 

I declared the OutsideFaceEnvironment object as the own surface name (see below) but the EnergyPlus showed me the severe error below. 

Surface:HeatTransfer,

    PAR LAT2,                !- User Supplied Surface Name

    WALL,                    !- Surface Type

    PAREDE L2,               !- Construction Name of the Surface

    GWEB,                    !- InsideFaceEnvironment

    OtherZoneSurface,        !- OutsideFaceEnvironment

    PAR LAT2,                !- OutsideFaceEnvironment Object

    NoSun,                   !- Sun Exposure

    2.8,                     !- Vertex 1 Z-coordinate {m}

    -1.9509,                 !- Vertex 2 X-coordinate {m}

    9.80785,                 !- Vertex 2 Y-coordinate {m}

    0,                       !- Vertex 2 Z-coordinate {m}

    0,                       !- Vertex 3 X-coordinate {m}

    0,                       !- Vertex 3 Y-coordinate {m}

    0,                       !- Vertex 3 Z-coordinate {m}

    0,                       !- Vertex 4 X-coordinate {m}

    0,                       !- Vertex 4 Y-coordinate {m}

    2.8;                     !- Vertex 4 Z-coordinate {m}



** Severe  ** CAUTION -- Interzone surfaces are usually in different zones 

3rd doubt ? Must Any construction of a surface have the same number of layers as the construction of his base surface? 



At room wall there is a door, the surface is made of three layers material construction and the door has just one layer. What?s the problem?  

   ** Severe  ** Construction PORTAConstrucion of interzone surface PORTA does not have the same number of layers as the construction PAREDE INT of adjacent surface PAR INT

 Thanks in advance!

Best,
