Create an opaque material that has no mass, which can be plugged into the "HB Opaque Construction" component.
name
Text to set the name for the material and to be incorporated into a unique material identifier.
r_value [Required]
Number for the R-value of the material [m2-K/W].
roughness
Text describing the relative roughness of a particular material. Must be one of the following: 'VeryRough', 'Rough', 'MediumRough', 'MediumSmooth', 'Smooth', 'VerySmooth'. (Default: 'MediumRough').
therm_absp
A number between 0 and 1 for the fraction of incident long wavelength radiation that is absorbed by the material. (Default: 0.9).
sol_absp
A number between 0 and 1 for the fraction of incident solar radiation absorbed by the material. (Default: 0.7).
vis_absp
A number between 0 and 1 for the fraction of incident visible wavelength radiation absorbed by the material. Default value is the same as the sol_absp.
mat
A no-mass opaque material that can be assigned to a Honeybee Opaque construction.
