Now choose the AC best suited to your region
THE BUREAU of Energy Efficiency ( BEE) has introduced a new star rating system—Indian Seasonal Energy Efficiency Ratio ( ISEER)— that takes into account different climatic zones in India. According to BEE, the new rating methodology will help usher in higher energy efficiency of appliances and reduce energy consumption under different Indian climatic conditions. This will enable Indian consumers to choose an AC that is best suited to the climatic conditions of a particular region. ISEER measures energy efficiency of air-conditioners based on a weighted average of performance at outside temperatures between 24 and 43ÊC based on Indian weather data. As per the Indian Weather Data Handbook of 2014, the weather profile of 54 major cities shows that 65 per cent of the total number of hours in a year have a temperature above 24ÊC. ACs in India have so far been tested at standard operating conditions of 35ÊC.
