Demand side management: energy efficiency (lighting system) in PTAR 1/ Nazri Nordin

Energy efficiency is important for improving the power consumption of any building or factory. Energy efficiency is increasingly becoming more important due to the increasing in costs of electrical energies. The advance developments in the technology in producing devices and products that can save energy enhance energy efficiency applications in the existing building. This report summarised the result of the energy efficiency study perform for the Perpustakaan Tun Razakl (PTAR l), main campus, Mara Institute of Technology, Shah Alam Selangor Darul Ehsan.
