Abstract
The present study was undertaken to assess the
energy efficiency of household lighting appliances through a lighting audit.
Data were collected using a standard interview schedule through interview and
observation methods. The study audits the age, wattage, usage pattern, and BEE
star rating of household lighting appliances. The findings revealed a shift
towards newer and more energy-efficient lighting technologies, particularly LED
bulbs and LED tube lights. Most households used lighting appliances for 1–4 hours
per day, while none reported using them for more than eight hours per day. LED
appliances had different BEE star ratings, whereas CFL appliances were
non-star-rated. The present study suggests that replacing older and
higher-wattage lighting appliances with low-wattage, energy-efficient LED
lighting can improve household energy efficiency, reduce electricity
consumption, and reduce household carbon emissions.
