Conservation of Energy: a Case Study on Energy Conservation in Campus Lighting in an Institution
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 4
Abstract
Fossil fuel reserve in India is depleting in a rapid way with development of the country. To meet the energy crisis, end user efficiency has an important role. This paper deals with the energy conservation in lighting system with the replacement of illumination scheme as there is an increasing demand of energy in all sectors in India. A number of commonly used lighting source and their comparison in terms of luminous efficacy was discussed. The campus lighting system comprising of T12 fluorescent light fixture for vigilance purpose of residential and institutional area of an existing institution can be replaced with proposed LED light fixture of equivalent output but of higher efficiency to reduce consumption of lighting energy. This improvement of end user efficiency will reduce the peak and average demand of electricity and hence reduce burden on electric network. The savings of annual energy with the proposed scheme is around 65% compared to the existing expense which is a significant achievement through energy conservation technique. Payback period of installation of proposed illumination scheme is slightly over three years. The initial investment for short term assessment is little higher but, in long term assessment the initial investment for the proposed scheme is will reduced by 50%as the operating life span of the proposed scheme is around five times the existing scheme.
