cea.geometry.geometry_reader module

algorithms for manipulation of building geometry

cea.geometry.geometry_reader.create_windows(df_prop_surfaces, gdf_building_architecture)[source]

Creates windows on exposed building surfaces according to building win-wall-ratio

Parameters:
  • df_prop_surfaces (DataFrame) – DataFrame containing all exposed building surfaces (this is the properties_surfaces.csv file from the radiation calculation)
  • gdf_building_architecture (GeoDataFrame) – GeoDataFrame containing building architecture - this is the architecture.shp file from the scenario input, containing the win_wall column with the window to wall ratio.
Returns:

DataFrame containing all windows of all buildings
Return type:

DataFrame
