Singapore buildings adopt alternatives to conventional air conditioning
Singapore is experimenting with technologies including chilled beams and passive displacement to reduce reliance on conventional air conditioning; authorities said at least 33 public and 14 private buildings had adopted alternative cooling technologies by mid-2026. [3] DP Architects said one building's combined system reduced energy consumption by more than 30% compared with conventional air conditioning, while a government study identified potential energy savings of up to 48%.

Why it matters
Cooling accounts for 40–60% of a building's energy consumption, and Singapore's building sector produces one-fifth of its emissions, making cooling equipment a substantial lever for reducing energy demand. [3]
Key insights
- Conventional air conditioning creates a feedback problem: outdoor compressor units release heat, while electricity generation can add greenhouse gases when it relies on fossil fuels. [3]
- Active chilled beams use ceiling-mounted panels fitted with cooling coils, providing a different delivery system from conventional air conditioning. [3]
- The reported savings are not interchangeable: more than 30% comes from designers' account of one building's system, while up to 48% is a government study's estimate of potential savings. [3]
