Use this component to create a custom opaque material, which can be plugged into the "Honeybee_EnergyPlus Construction" component.
This component requires you to know a lot of the characteristics of the material and, you may want to borrow some characteristcs of a similar material in the library. Use the "Honeybee_Call From EP Construction Library" and the "Honeybee_Decompose EP Material" to help with this.
If you are not able to find all of the necessary material characteristcs and your desired material is relatively light, it might be easier for you to use a "Honeybee_EnergyPlus NoMass Opaque Material."

Inputs

NameIDDescriptionType
Name_nameA text name for your Opaque Material.Goo
Roughness_roughness_A text value that indicated the roughness of your material. This can be either "VeryRough", "Rough", "MediumRough", "MediumSmooth", "Smooth", and "VerySmooth". The default is set to "Rough".Goo
Thickness_thicknessA number that represents the thickness of the material in meters (m).Goo
Conductivity_conductivityA number representing the conductivity of the material in W/m-K. This is essentially the heat flow in Watts across one meter thick of the material when the temperature difference on either side is 1 Kelvin.Goo
Density_densityA number representing the density of the material in kg/m3. This is essentially the mass one cubic meter of the material.Goo
Specific Heat_specificHeatA number representing the specific heat capacity of the material in J/kg-K. This is essentially the number of joules needed to raise one kg of the material by 1 degree Kelvin.Goo
Therm Absp_thermAbsp_An number between 0 and 1 that represents the thermal abstorptance of the material. The default is set to 0.9, which is common for most non-metallic materials.Goo
Sol Absp_solAbsp_An number between 0 and 1 that represents the abstorptance of solar radiation by the material. The default is set to 0.7, which is common for most non-metallic materials.Goo
Vis Absp_visAbsp_An number between 0 and 1 that represents the abstorptance of visible light by the material. The default is set to 0.7, which is common for most non-metallic materials.Goo

Outputs
