aperture_files(black_out=False, rel_path=True)

Return list of files for apertures.

This list includes both geometry and modifier files. This method will raise a ValueError if it cannot find a modifier file with the same name as the geometry file.

Parameters

• black_out (str) – Set black_out to True for “isolated” studies for aperture groups.

• rel_path (str) – Set rel_path to False for getting full path to files. By default the path is relative to study folder root.

aperture_folder(full=False)

Parameters

full – A boolean to weather the path should be a full path or a relative path (default: False).

Returns

Path to folder.

aperture_group_files_black(exclude=None, rel_path=False)

Return list of files for black aperture groups.

Parameters

• exclude – Identifier of aperture groups to exclude from the list of black aperture groups files. This input can be either a single aperture group identifier or a list of aperture group identifiers.

• rel_path – Set rel_path to True for getting full path to files. By default the path is relative to study folder root.

aperture_group_folder(full=False, interior=False)

Aperture group folder path.

Parameters

• full – A boolean to note if the path should be a full path or a relative path (default: False).

Returns

Path to folder.

aperture_groups(interior=False, reload=False)

List of apertures groups.

Parameters

• interior (bool) – Boolean switch to return interior dynamic apertures.

Returns

A list of dynamic apertures.

aperture_groups_states(full=False, interior=False)

Return states information for aperture groups.

Arg:

full: A boolean to note if the path should be a full path or a relative path

(default: False).

groups.

bsdf_folder(full=False)

Parameters

full – A boolean to weather the path should be a full path or a relative path (default: False).

Returns

Path to folder.

combined_receivers(folder='receiver', auto_mtx_path=False)

Write combined receiver files to folder.

This function writes a combined receiver file of the aperture groups for all grids in the folder. It will look for the light paths (aperture groups) of the grid and include only aperture groups that has a mtx file. This is intended for matrix-based daylight simulations, e.g. 3-phase, in which a view matrix is calculated. The combined receiver file allow multiple view matrices to be calculated at once, while still saving the result of each aperture group in a unique view matrix file.

Arg:

folder: A path of the target folder to write files to (default: ‘receiver’). auto_mtx_path: If set to True, then the path of the view matrices will be

specified automatically.

Returns

A dictionary containing grid identifiers as keys and the receiver rad files as values.

daylight_matrix_files(aperture, receiver=None)

Files to be included in daylight matrix calculation for an aperture.

Target can be Sky or another aperture.

dynamic_scene(indoor=False, reload=False)

List of dynamic non-aperture geometries.

Parameters

• indoor (bool) – A boolean to indicate if indoor dynamic scene files should be returned (default: False).

• reload (bool) – Dynamic geometries are loaded the first time this method is called. To reload the files set reload to True.

dynamic_scene_folder(full=False, indoor=False)

Dynamic scene folder path.

Parameters

• full – A boolean to note if the path should be a full path or a relative path (default: False).

• indoor – Set to True to get the path for indoor dynamic scene folder.

Returns

Path to folder.

classmethod from_model_folder(model_folder, config_file=None)

Use model folder instead of project folder.

Parameters

• model_folder (str) – Model folder as string. The folder will be created on

default folder.cfg in honeybee-radiance-folder will be used.

grid_data_all(info_from_model=False)

This is an internal function that for a specified info_json, returns the consolidated grid data, that includes grid names,counts and identifiers, as a single dictionary.

Parameters

• info_from_model – If set to True, data will be retrieved using

Parse the appropriate grids_info file to return high level information about the sensor grids contained in the model folder.
