Glass Material

- [source code]

Create a window material to describe a single glass pane corresponding to a layer in a window construction. This material can be plugged into the "HB Window Construction" component.

Inputs

• name

  Text to set the name for the material and to be incorporated into a unique material identifier.

• thickness [Required]

  Number for the thickness of the glass layer [m]. Typical values range from 0.003 meters (3 mm) to 0.012 meters (12 mm).

• transmittance

  Number between 0 and 1 for the transmittance of both solar radiation and visible light through the glass at normal incidence. (Default: 0.85 for clear uncoated glass).

• reflectance

  Number between 0 and 1 for the reflectance of both solar radiation and visible light off of the front side of the glass at normal incidence. (Default: 0.075 for clear uncoated glass).

• t_infrared

  Long-wave transmittance of the glass at normal incidence. (Default: 0).

• emiss_front

  Number between 0 and 1 for the infrared hemispherical emissivity of the front side of the glass. (Defaul: 0.84, which is typical of clear glass).

• emiss_back

  Number between 0 and 1 for the infrared hemispherical emissivity of the back side of the glass. (Default: 0.84, which is typical of clear glass).

• conductivity

  Number for the thermal conductivity of the glass in W/m-K. (Default: 0.9, whih is typical of clear glass).

Outputs

• mat

  A window material that describes a single glass pane and can be assigned to a Honeybee Window construction.
