New star rating methodology - Indian Seasonal Energy Efficiency Ratio (ISEER) for ACs
Q. Which of the following is/are true regarding Indian Seasonal Energy Efficiency Ratio (ISEER)?
1) Ratings based on ISEER are mandatory from April 2016.
2) Star-1 is the least efficiency level of ACs that can be sold in the market.- Published on 26 Aug 16a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
ANSWER: Neither 1 nor 2
- 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.
- Some of the leading manufacturers have already adopted the rating for inverter air conditioners.
- 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.
- Now as per latest notification, from January 2016, Star-2 is the least efficiency level to be sold in the market, hence variation in power consumption is compared between Star-5 (most efficient) and Star-2 (least efficient) air conditioners.
