The Centre for Science and Environment (CSE) has called for a revision of air conditioning energy consumption standards, after tests found significant inefficiencies at higher ambient temperatures. A report by CSE, a New Delhi-based research and advocacy organization, concluded that current topperforming air conditioner efficiency can drop nearly 30% when the temperature reaches 40°C. The study shows that in the hottest days of summers, when temperatures are in the 40°C to 50°C range, ACs ranked highest in the classification system can consume 10% to 28% more power than their declared capacity. Energy efficiency further deteriorates when users lower the room temperature to levels below 27°C. CSE has called on the Indian government and industry entities to strengthen energy efficiency standards and test procedures to the level of those in many developed nations.
