The Bureau of Energy Efficiency (BEE) has introduced a new star rating methodology called Indian Seasonal Energy Efficiency Ratio (ISEER) for air conditioners.
This evolved rating methodology factors in variance in higher temperature in India and rates air conditioners accordingly.
Consumers can now purchase air conditioners with higher efficiency leading to lower electricity bills. Consumers can now purchase air conditioners with higher efficiency leading to lower electricity bills.
Keeping the performance of air conditioners during higher temperature in mind, ISEER will address the different climatic zones in India and higher temperature.
ISEER measures energy efficiency of air conditioners based on a weighted average of the performance at outside temperatures between 24 and 43 degree C based on Indian weather data.
Ratings based on ISEER have been introduced on a voluntary basis for Variable Speed (Inverter) Air Conditioners since June 2015 and proposed to be merged with fixed speed air conditioners in the mandatory regime from January 2018.
