Singapore Looks for New Ways to Stay Cool Beyond Air-Conditioning

Published 2026-11-01

Singapore has long been known as an "air-conditioned nation," because almost every home, office and shopping centre relies on air-conditioning to beat the hot and humid weather. However, air-conditioners use a large amount of electricity, and they release heat into the surrounding air. Now, the country is testing other ways to keep buildings cool.

One of the options being tried is chilled beams. These are metal units fitted to the ceiling that circulate cold water, which cools the room without blowing out strong air. Experts say this method can use less energy than traditional systems. Another approach is "passive cooling," which uses the design of a building to reduce heat. This can include features such as shading, good airflow and materials that do not absorb much heat from the sun.

These experiments are part of a wider effort to reduce energy use and address climate change. As temperatures in Singapore continue to rise, cooling is becoming an important issue for both households and businesses. Some building owners are already looking at whether these new systems could be used in existing buildings, not just new ones.

It is not yet clear whether these alternatives will replace air-conditioning in most places. However, the trials show that Singapore is willing to change how it keeps cool. For residents, this could mean more comfortable and more energy-efficient buildings in the future.
