Scenario Generator

Overview

A scenario is a specific set of conditions about which we would like to either know the detailed lighting performance of a luminaire, or simply if the luminaire meets the performance requirements of a specific Lighting Standard.

A scenario is standard-specific, so the initial selection is the Standard, as this determines the options available to configure the scenario.

ACE currently supports the following standards:

  • EN13201 ME & M Class (2003 and 2015)
  • EN13201 S & P Class (2003 and 2015)
  • EN13201 CE & C Class (2003 and 2015)
  • BS5489 P Class (2013)
  • CIE115 M Class (2010)
  • CIE115 P Class (2010)
  • CIE115 C Class (2010)
  • IES RP-8 (2000 and 2014)

Scenario Parameters

Once a standard has been selected, the remaining parameters that define the scenario can be specified. The exact definition varies by standard, but for a scenario using the EN13201 M Class standard, these would include:

  • Dual Carriageway
  • Road surface (R1, R2, R3 etc)
  • Number of lanes
  • Lane width
  • Central Reserve width
  • Hard Shoulder
  • Luminaire mounting height
  • Overhang
  • Tilt
  • Configuration (Staggered, opposite etc)
  • Maintenance factor
  • Column spacing

Scenario parameters are broadly the same across all standards for illuminance classes. The lane width and number of lanes is replaced with total width. Road surface type is only necessary for luminance-based calculations.

Luminaire Selection

Add a Luminaire to test and a single scenario has been defined. However, to investigate luminaire performance, or to find the optimum product over a range of different configurations, many more scenarios will be required. The Scenario Generator allows the definition of multiple values for each parameter, either entered as individual values, or as a starting value and a step size. The Scenario Generator also allows multiple luminaires to be included (previously uploaded by the Photometry Manager), which results in a scenario definition that can test many products against a wide range of lighting configurations, which could be hundreds of configurations, thousands, or many millions.

Saving Scenarios, Templates and Submission

The scenario definition can be saved to your local workspace to be edited later, saved as a template for future use, or submitted for processing so that all of the defined scenarios are calculated and the luminaire performance data for each configuration is generated and saved to a database.
