Roadmap towards Sustainable and Energy-Efficient Space Cooling in the Association of Southeast Asian Nations

Roadmap Towards Sustainable and Energy-Efficient Space Cooling in ASEAN

Executive Summary

Space cooling is rapidly becoming one of the largest consumers of electricity in buildings, both globally and within the Association of Southeast Asian Nations (ASEAN). Over the past few decades, the use of electricity for cooling in buildings across ASEAN has seen significant growth. Currently, only 15% of households in Southeast Asia own air conditioners, while fans account for around another 9% of residential energy use.

With ongoing economic development and population growth, the International Energy Agency (IEA) projects that air conditioner ownership in ASEAN Member States (AMS) will continue to increase. By 2040, the electricity demand from space cooling in the region could reach 300 TWh, which is roughly equivalent to the combined total electricity consumption of Indonesia and Singapore.

The Roadmap towards Sustainable and Energy-Efficient Space Cooling in ASEAN aims to leverage policy tools to drive energy efficiency improvements in space cooling technologies, such as air conditioners and fans. This roadmap sets ambitious milestones to guide the implementation of these technologies and subsequent actions across ASEAN.
