Equipment Performance Studies

Illumination & Lighting

The studies involve measuring the illumination level at various locations as well as analyzing type and location of various light fittings to assess the system efficacy and opportunities to optimize the overall system performance.

The typical scope of the work covers

  • Noting down the illumination (Lux) level at various locations.
  • Gathering data of types of fittings, switchgear.
  • Assessing with the operational practices and switching controls
  • Analysing the data with norm / general practices
  • Suggesting ways for improvement, as applicable
  • Submitting the report

  • A team of one engineer is deputed to carry out the studies and furnishing the report. The field visit is typically for 5 to 6 hours; during which up to 80 locations can be covered depending upon initial preparations and support from the plant team.

    Although not a part of regular assignment, the following parameters can also be also measured, if possible and requested by the plant

  • Measuring illumination level at various locations to compute average value
  • Noting down the various types of fitting including type, rating and ballast to compute the total power consumption.
  • Measuring room dimension to determine the area as well as room index
  • Computing Lighting Power Density (LPD) and Luminance per LPD (Lux / (W/M 2 ) and comparing the same against the standard norms provided by BEE to determining Installed Load Efficacy Ratio (ILER)
  • Projecting the controllable loss and saving potential based on the present ILER and desired ILER of 75%.
  • Computing the Circuit Power as well as Lighting Power Density
  • Estimating Installed Load Efficacy as well as Lamp Circuit Efficacy
  • Assessing Installed Power Density.
  • Analysing the losses and suggesting ways for improvement, as applicable
  • Submitting the report
