Lighting Parameters Assessment and Efficient Energy: a Lighting Audit of a Classroom K. Sudhakar

This study focuses on the performance of existing lighting installation in the classroom of Energy Centre, MANIT, Bhopal. A detailed lighting audit is carried out by photometric lumens method to achieve/optimise the lighting system. The performance of existing lighting installation has been assessed based on installed efficacy (Lux/W/m2) and Installed Load Efficacy Ratio. Efficient lighting could be achieved by replacement of high power consumption lamps with energy efficient lighting. In a different method, Installed lumens in a classroom are compared with the required lumens and accordingly number of lamps to be added or removed is determined. Actual photometric measurements are done at different benches of the classroom (visual surfaces) with the help of a lux meter for different sessions of a day. The required lumens can also be achieved by providing sufficient passage for natural light. 3D model of the same classroom with the existing lighting installations was designed and created by using lighting design software DIALux evo 3. A prototype of light intensity control module is also designed and tested.
