Energy Efficiency in Lighting

Sonal Desai, Ph.D.


Course Outline

The course discusses about fundamental definition and terminology used in lighting system including why efficacy is used instead of efficiency. It is important to understand basics of lighting system before conducting energy audit of the same. Different lighting systems commercially and industrially used are talked in the next section including their comparison. Conventional and tailor made control devices used in this field are discussed in subsequent section. Step wise methodology to conduct the energy audit is presented in next section followed by different energy saving methods. Finally a comprehensive checklist is attached at the last which helps to identify rectify energy saving opportunities.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will:

Intended Audience

This course is intended for Mechanical and Electrical engineers and can be taken by other branch engineers also.

Benefit for Attendee

Attendee of this course will be able understand lighting system, conduct audit of lighting system and recommend suggestion in the existing lighting system. 

Course Introduction

Lighting system consumes 10 to 15 % of our total power consumption. Inefficient lighting systems are responsible for more electricity production and green house gas generation. Audit of lighting system includes measurement of illumination levels, improving lighting system efficiency, reducing operating hours, checking possibilities of retrofits and use of suitable lighting control devices.
