Energy Efficiency Services Limited
Under the National Energy Efficient Fan Programme, EESL provides BEE 5 Star rated ceiling fans which are 30% more energy efficient than conventional fans. Fans will be sold for Rs. 1,150 per fan. EESL has distributed 6.2 lakh energy efficient fans under this scheme which will save 2.4 lakh kWh and Rs 8.2 lakh per day to the consumers. The price difference is Rs. 500 which is the primary reason for its low penetration, along with the lack of awareness. With the usage of these energy efficient fans it is estimated that consumer’s electricity bills will reduce by about Rs. 700-730 per year, and recover the extra cost in less than 2 years.
Cellular shades
Windows and doors make up for approximately one-third of a home’s total thermal loss, according to the Natural Resources Defense Council. This applies to heat loss in winter, and entry of undesired heat in summer. When air inside the room comes in contact with windows, it is cooled or warmed. By convection this air then circulates around the room. Cell shapes in the blinds hold trapped air and create a barrier between the window surface and the room. Shades, however, provide only slight control of air infiltration.
