Improved Illumination Levels and Energy Savings by Uplamping Technology for Office Buildings

This study introduces a simple solution for uplamping and its energy saving for office lighting in the buildings visited in Gurgaon, Manesar and Noida around the capital of India i.e. Delhi, by discussion with the technical and maintenance staff. Study was carried out to know what is the existing lighting system used, and suggestions of efficient lighting system with support of lighting energy simulation tool i.e. DIALux are given. The selected project as a case study is the Human Resources Developing Institute of Bharat Heavy Electricals Ltd BHEL (office building). The result of the efficient system in the building shows that, uplamping with fluorescent lamps and CFL has achieved in energy saving of 42% and 65% respectively, and increase in lux level by 30% for both.
