“Space cooling demand experienced the high- est annual growth among all buildings end uses in 2021 and accounted for nearly 16 per cent of buildings sector final electricity consumption (about 2 000 TWh).”
The IEA said efficiency standards are a key measure to avoid the lock-in of inefficient air- conditioning units in coming decades, together with passive, nature-based and alternative
lower efficiencies than the ones of best available technologies, the report said.
In the Net Zero Emissions by 2050 Scenario, indirect CO2 emissions associated with space cooling demand by 2030 fall to about one-third of those in 2021, with a decrease in emissions intensity per unit six times faster than over the past decade.
Energy demand for space cooling has risen at an average pace of four per cent per year since 2000, twice as quickly as for lighting or water heating.
