Super-efficient ACs Cut 60 Percent Energy Use: Industry Leaders
Amid India's unprecedented heat wave and increasing demand for cooling solutions, prominent figures from the air conditioning and HVAC sector gathered at a recent summit to address one of the nation's most critical issues - providing cost-effective and resilient comfort for a country experiencing rapid warming.
As sales of air conditioners surge to unparalleled levels and 76 percent of the population is exposed to extreme heat risks, the onset of summer has been marked by a sudden and intense heatwave.

The recent temperature spike in Mumbai, reaching 38.7°C, nearly six degrees higher than the March average, serves as a stark reminder of the escalating challenges posed by climate change.
Industry experts presented an ambitious vision for the future: widespread adoption of highly efficient, humidity-optimized air conditioning systems that could reduce energy consumption by 60 percent, decrease peak power demand by half, and revolutionize India's approach to cooling.
The pressing nature of the current situation was emphasized during the session titled "Can Today's Air Conditioners Keep Up with a Hotter, More Humid World? Delivering Affordable, Efficient Comfort for the Global South," hosted by RMI and CEPT University at the Jio World Convention Centre.
By 2050, it is projected that the country will have more than one billion room air conditioners in operation, leading to a significant increase in electricity demand for cooling compared to 2022.
The Rocky Mountain Institute (RMI) has pointed out that current air conditioning systems are designed primarily for temperature control and do not effectively address high humidity levels. This often results in people lowering the thermostat to combat discomfort from humidity, leading to excessive cooling and energy wastage.

Field tests conducted by RMI in Palava City over a nine-month period revealed that many air conditioners on the market today consume more than 30 percent additional energy under real-world conditions to manage humidity. Unfortunately, consumers are not informed about this additional energy usage related to humidity control when purchasing air conditioners, as current performance metrics do not take this into account.
It is estimated by industry experts that 60 percent of districts in India, which accounts for 76 percent of the population, are currently facing an elevated risk of extreme heat.
Additionally, in Southeast Asia, there is a projected increase in demand for air conditioners from 40 million to 300 million units by the year 2040. Cooling systems are already responsible for 10 percent of peak electricity usage and this figure is expected to rise to 30 percent by 2040.
Industry experts highlighted that India is currently at a crucial turning point, bolstered by a solid policy framework outlined in the India Cooling Action Plan, robust energy efficiency strategies, a burgeoning manufacturing sector, and escalating investments in research, development, and supply networks. These advantages position the country to play a pivotal role in shaping the worldwide landscape of air conditioning, catering to both domestic demands and emerging as a frontrunner in sustainable cooling exports.

The conversation underscored the nation's capability to take the lead in advancing and implementing cutting-edge, highly efficient, humidity-optimized air conditioning systems. It was mutually recognized by stakeholders that cooperation within the cooling industry, involving purchasers, producers, regulatory bodies, and policymakers, is crucial for instigating significant market reform.
With the ongoing increase in temperatures and humidity, the necessity of implementing high-efficiency and environmentally friendly air conditioning systems is no longer a choice but a crucial mandate at the national level. The progress observed during the meeting positions India to take the lead globally in providing cost-effective, durable, and environmentally conscious cooling solutions for the future.
