The commercial sector includes retail shops, offices business and government, hotels, lodge and restaurants,
schools and other workplaces. The form of energy used here is same as that of residential type with small
change in proportions. Commercial lighting consumes about 55-60% of the consumption of this sector and
generally the most wasteful component of commercial use. A number of case studies indicate that more
efficient lighting and elimination of over-illumination can reduce lighting energy by 40-50%. Space
conditioning (Heating ventilating and cooling) is again the single biggest consumption area but it represents
only about 30-35% of the energy use of commercial buildings
schools and other workplaces. The form of energy used here is same as that of residential type with small
