Condensation calculator - [source code]
Use this component to calculate the Dew Point, Relative Humidity and Condensation on each layer of a wall. It accounts the air films (internal and external).

cnstrName [Required]EnergyPlus construction name
surfaceType [Optional]An integer value from 0 to 3 that represents one of the following surface types: 0 - Exterior Wall/Window 1 - Exterior Roof 2 - Exposed Floor
internalTemp [Required]Indoors temperature of room
outTemp [Required]Outdoors temperature of room
internalRelativeHumidity [Required]Indoors relative humidity
basePoint [Default]An optional point with which to locate the 3D chart in the Rhino Model. The default is set to the Rhino origin at (0,0,0).
scale [Default]The scale of the surface type section. The default is set to 1.
bakeIt [Optional]An integer that tells the component if/how to bake the bojects in the Rhino scene. The default is set to 0. Choose from the following options: 0 (or False) - No geometry will be baked into the Rhino scene (this is the default). 1 (or True) - The geometry will be baked into the Rhino scene as a colored hatch and Rhino text objects, which facilitates easy export to PDF or vector-editing programs. 2 - The geometry will be baked into the Rhino scene as colored meshes, which is useful for recording the results of paramteric runs as light Rhino geometry.
