Use this component to create a custom material for glass, which can be plugged into the "Honeybee_EnergyPlus Construction" component.
It is important to note that this component creates a material that represents a single pane of glass, which can be combined with the "Honeybee_EnergyPlus Window Air Gap" to make multi-pane windows. If you have specifications for a whole window element and not individual panes of glass and gas, you are better-off using the "Honeybee_EnergyPlus Window Material" component

Inputs

NameIDDescriptionType
Name_nameA text name for your glass material.Goo
Thicknessthickness_A number that represents the thickness of the pane of glass in meters. The default is set to 0.003 meters (3 mm).Goo
Solar TransmittancesolarTransmittance_A number between 0 and 1 that represents the transmittance of solar radiation through the glass at normal incidence. The default is set to 0.837, which it typical for clear glass without a low-e coating.Goo
Solar ReflectancesolarReflectance_A number between 0 and 1 that represents the reflectance of solar radiation off the glass at normal incidence. The default is set to 0.075, which is typical for clear glass without a low-e coating.Goo
Visible TransmittancevisibleTransmittance_A number between 0 and 1 that represents the transmittance of only visible light through the glass at normal incidence. This is usally very close to the solarTransmittance_ for non-low-e-coated glass but can differ if the glass has a low-e coating. The default is set to 0.898, which is typical for clear glass without a low-e coating.Goo
Visible ReflectancevisibleReflectance_A number between 0 and 1 that represents the reflectance of only visible light off the glass at normal incidence. This is usally very close to the solarReflectance_ for non-low-e-coated glass but can differ if the glass has a low-e coating. The default is set to 0.081, which is typical for clear glass without a low-e coating.Goo
Front EmissivityfrontEmissivity_A number between 0 and 1 that represents the infrared hemispherical emissivity of the front (outdoor-facing) side of the glass. This number is usually pretty high for non-low-e-coated glass but can be significantly lower for low-e coated glass. The default is set to 0.84, which is typical for clear glass without a low-e coating.Goo
Back EmissivitybackEmissivity_A number between 0 and 1 that represents the infrared hemispherical emissivity of the back (indoor-facing) side of the glass. This number is usually pretty high for non-low-e-coated glass but can be significantly lower for low-e coated glass. The default is set to 0.84, which is typical for clear glass without a low-e coating.Goo
Conductivityconductivity_A number representing the conductivity of the glass in W/m-K. The default is set to 0.9, which is typical for clear glass without a low-e coating.Goo
