BEE tweaks AC power ratings

The new methodology called Indian Seasonal Energy Efficiency Ratio (ISEER) will address the different climatic zones in India and higher temperature.

New Delhi: Bureau of Energy Efficiency (BEE) has introduced a more efficient star rating methodology for air conditioners which takes into account variance in higher temperature in India and rates air conditioners accordingly.

The new rating system measures energy efficiency of air conditioners based on a weighted average of the performance at outside temperatures between 24 and 43 degree Celsius. Till now air conditioners in India had been tested under a standard operating conditions of outside temperature of 35 degree Celsius.

The new methodology called Indian Seasonal Energy Efficiency Ratio (ISEER) will address the different climatic zones in India and higher temperature.

Consumers can now purchase air conditioners with higher efficiency leading to lower electricity bills. Bureau of Energy Efficiency, secretary, Sanjay Seth said that the new methodology for rating system will bring in higher energy efficiency of appliances and reduce energy consumption. He further said that the standards have been developed while keeping changing Indian temperature in mind.

BEE has been continuously tightening the standards such that, the Star-5 in 2010 became Star-3 in 2015 and will become Star-1 in 2018 as per new ISEER methodology.

The weighted average Energy Efficiency Ratio (EER) of AC has increased from 2.6 in 2006 to 3.26 in 2015, which is an increase of 25 per cent in efficiency due to tightening of standards. Since 2010 Bureau of Energy Efficiency has mandated air conditioners as a mandatory-labelled appliance under Energy Conservation Act and since then air conditioners cannot be sold without star label.
