Case Report

Case Study of Energy Saving in Building and Architectural Engineering Department, Bahahuddin Zakariya University Multan by Replacing Conventional Lights with LED Bulbs



Artificial lighting uses a significant percentage of the electrical power being consumed globally. Power generation is one of the major issues for a progressing country like Pakistan, conversely the demand is growing due to increased population and advanced life style. This could lead to severe power shortages. To tackle this situation, a way is to reduce the demands by using energy efficient technologies. This will lead to required lighting provision by using lesser power. Using efficient bulbs like Light emitting diode (LED) instead of conventional fluorescent tube lights (FTL) provides energy efficient lighting system. A new lighting system is designed for the chosen building using DIALux 4.12 simulation software which fulfills the standard requirements of Illuminating engineers society of North America (IESNA). Installation of new lamps proved that the system consumes 47% lesser energy compared to the old conventional system and calculations shows a payback period of 1.734 years for the initial costs. These figures prove the economy of the newly designed system.
