honeybee_radiance_command.options.gendaylit module

class honeybee_radiance_command.options.gendaylit.GendaylitOptions

Bases: honeybee_radiance_command.options.optionbase.OptionCollection

Gendaylit command options.

to_file(folder, file_name, mkdir=False)

Write options to a file.

to_radiance()

Translate options to Radiance format.

update_from_string(string)

Update options from a standard radiance string.

If the option is not currently part of the collection, it will be added to additional_options.

property L

A tuple of direct-normal-illuminance (lm/m^2) and diffuse-horizontal-illuminance (lm/m^2) values.

property O

Output

A value of 0 will output in W/m^2/sr visible radiation, A value of 1 will output in W/m^2/sr solar radiation, A value of 2 will output in lm/m^2/sr luminance.

property P

Espilon data a.k.a Perez parameters

property W

A tuple of direct-normal-irradiance (W/m^2) and diffuse-horizontal-irradiance (W/m^2) values.

property a

Site latitude.

The value is site latitude in degrees north. (Use negative angle for south latitude.) This is used in the calculation of sun angle.

additional_options

property ang

Altitude & azimuth

This option gives the solar angles explicitly. The altitude is measured in degrees above the horizon, and the azimuth is measured in degrees west of south.

property command

Command name.

property g

Average ground reflectance.

This value is used to compute skyfunc when Dz is negative.

property m

Standard meridian.

The site standard meridian is a value in degrees west of Greenwich. (Use negative angle for east.) This is used in the calculation of solar time. Be sure to give the correct longitude also! If a time zone or solar time is given directly, then this option has no effect.

property o

Site longitude.

The value is site longitude in degrees west. (Use negative angle for east longitude.) This is used in the calculation of solar time and sun angle. Be sure to give the corresponding standard meridian also! If solar time is given directly, then this option has no effect.

property options

Print out list of options.

property s

Generate source description of the sun.

property slots

Return slots including the ones from the baseclass if any.
