Energy conservation through lighting audit

Lighting constitutes a major portion of electricity consumption in commercial and industrial sector. To some extent, developing countries like Pakistan can meet the energy demand by incorporating energy conservation policy in their Demand Side Management (DSM) program. This paper presents a method to optimize the energy consumption by carrying out lighting audit. The data of Siemens Pakistan department Transformer Business Unit (TBU) is used here as a case study. In the present study, lighting energy demand is controlled by proposing an efficient lighting scheme, using energy efficient lamps, lamps relocation and implementing lighting maintenance schedule. The result shows that around 10.41% of the current energy could be saved by adopting lighting conservation policy.
