The Central Government in consultation with the Bureau of Energy Efficiency (BEE) has notified new energy performance standards for Room Air Conditioner (RACs).

24⁰C default setting

• The 24⁰C default setting has been made mandatory from Jan 1, 2020 for all room air conditioners covered under the ambit of BEE star-labelling program vide this notification.
• Additionally, the Indian Seasonal Energy Efficiency Ratio (ISEER) as per the new standards will range from (3.30 – 5.00) for split and (2.70 – 3.50) for window air conditioners, which will be applicable from 1^st January 2021 onwards.
• ISEER is the energy performance index used for Room Air Conditioners (RACs) and its assessment is based on the bin hours defined in ISO 16358.

Voluntary star labelling program

• BEE launched the voluntary star labelling program for fixed-speed room air conditioners (RACs) in 2006, and this program became mandatory on 12^th January 2009.
• Thereafter, in 2015, voluntary star labelling program for inverter room air conditioners was launched and which was made mandatory with effect from 1^st January 2018.
• The BEE star labelling program for Room Air Conditioners now covers both fixed and inverter RAC up to a cooling capacity of 10,465 watts (2.97 TR).
• Continual enhancement in performance levels has resulted in substantial energy efficiency improvement of about 43% in the minimum energy performance standards (MEPS) for split units, which are the most popular RACs sold in the market.

About BEE

• BEE is a statutory body under the Ministry of Power, Government of India.
• It is assisted in developing policies and strategies with the primary objective of reducing the energy intensity of the Indian economy.
• BEE coordinates with designated consumers, designated agencies, and other organization to identify and utilize the existing resources and infrastructure, in performing the functions assigned to it under the energy conservation act.
