This command calculates the Lighting Power Density and/or Upward Waste Light Ratio based on the luminaires within a user defined area.
Lighting Power Density Areas (LPD Areas) calculate the lighting power density based on the number of luminaires within a user-defined polygon. Lighting power density is defined as watts per area, where area is dictated by the current display units (ft. or m) in AGi32. Example: If the current display units are feet, the LPD is defined as watts/ft2. The watts are extracted from the photometric file when the luminaire is defined.
Upward Waste Light Ratio (UWLR) calculates the proportion of the luminous flux emitted by the luminaire above the horizontal in its installed position.
The LPD/UWLR Area dialog allows the user to specify the parameters for a new or existing LPD/UWLR Area.
