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.
Roof garden
A study at the National Research Council of Canada showed the differences between roofs with gardens and roofs without gardens against temperature. The study shows temperature effects on different layers of each roof at different times of the day. Roof gardens are obviously very beneficial in reducing the effects of temperature against roofs without gardens. “If widely adopted, rooftop gardens could reduce the urban heat island, which would decrease smog episodes, problems associated with heat stress and further lower energy consumption.”
