Window Type Element

One WindowType should be created for each type of window.

Supported Attributes:

Attribute Description
Id This identifier.

Supported Children:

Element Description
Name

For model information, the value of the Name element is composed by the Family Name and the Family Type name. Sample: Fixed: 36" x 72". Unwanted characters are filtered out, since this can cause issues in downstream simulation applications. The following special characters are filtered out: Period("."); Apostrophe("'"); Backslash("\"); Semicolon(";"); DollarSign("$");

If the window type originates from an analytical or schematic type, the value of the Name element is collected from the name for the Analytical Construction.

Description

If the window type originates from an analytical or schematic type, the value of the Description element is collected from the description

for the Analytical Construction.

U-value Overall conductance. The value for this element is collected from the type property Heat Transfer Coefficient (U). The unit will always be WPerSquareMeterK.
SolarHeatGainCoeff

The center of glass solar heat gain coefficient. Each SolarHeatGainCoeff element can have a solarIncidentAngle attribute indicating the Incident angle of the SHGC value. If there is no SolarIncidentAngle attribute this indicates it's diffuse.

The SHGC value is the fraction of incident irradiance that enters through the glazing and becomes heat gain.

For model information, the value for this element is collected from the type property Solar Heat Gain Coefficient in the group Analysis Properties if available.

Transmittance The light transmitting property of a window. This value takes into account the spectral response of the human eye in addition to the solar-weighted solar transmittance. For model information, the value for this element is collected from the type property Visual Light Transmittance in the group Analysis Properties if available. The unit attribute will be set to "Fraction". The type attribute will be set to "Visible". The surfaceType attribute will be set to "Both".
