Around 99% of private residences have air conditioners. New systems, including chilled beams and passive displacement cooling, are being introduced, with one office complex reporting energy savings exceeding 30% compared with conventional air conditioning.

A 2024 government study found that alternative cooling technologies could reduce energy consumption by up to 48%. By mid-2026, at least 33 public and 14 private buildings had adopted these systems.

Although installation costs remain higher than conventional air conditioning, supporters argue that lower operating expenses compensate over time. Singapore aims to achieve net-zero carbon emissions by 2050.
