Global Exchange on Efficiency: Cooling

Welcome to the home of the IEA's Global Exchange on Efficiency, a platform for exchanging data, insights, resources and best practice on energy efficiency. Today this site brings together data and information on cooling and serves as a progress tracker for the Kigali Amendment of the Montreal Protocol.


  • Policy coverage
  • Cooling technologies
  • Energy use & emissions

Policy coverage and minimum standards

Select desired countries or regions on the map to see the cooling equipment minimum efficiency ranges covered by existing standards.

Performance standards

Cooling technology performance for selected countries

Compare the range of minimum available to best available efficiencies for residential and commercial air conditioners (ACs) across select countries and regions.

  • Residential AC - energy efficiency ratio
  • Residential AC - seasonal efficiency ratio
  • Commercial AC - coefficient of performance
