Hot in the city: Energy crisis tests Singapore’s air-con addiction
Hot in the City: Energy Crisis Challenges Singapore’s Air-Conditioning Dependence
Singapore, a nation synonymous with air conditioning, is adjusting office temperatures to 25°C as energy costs surge due to the Iran conflict. Public buildings are now incorporating energy-saving technologies such as LED lighting and intelligent sensors to cut consumption. This shift aligns with broader regional efforts, including Thailand’s directive to maintain air conditioners at 26-27°C.
The city-state’s reliance on Middle Eastern oil and gas, which flow through the Strait of Hormuz, has intensified as the war disrupts global fuel supply chains. In 1999, Lee Kuan Yew, Singapore’s founding father, highlighted air conditioning’s transformative role in tropical climates. He noted that installing climate control in civil service buildings was essential for maintaining public efficiency.
“The first thing I did upon becoming prime minister was to install air conditioners in government buildings,” Lee said. “This allowed people to work indoors regardless of the heat outdoors.”
Today, nearly all offices in Singapore feature air conditioning, though its usage has become a subject of debate. Employees often wear cardigans during work hours, a habit born from consistently low indoor temperatures. Unlike open-air markets in neighboring countries, Singapore’s malls and department stores are fully climate-controlled, creating stark temperature contrasts for pedestrians.
Public transport and buses are also air-conditioned, reflecting the city’s deep integration with cooling systems. Most households have units installed, often running continuously. The Ministry of Sustainability and the Environment emphasized that raising the thermostat by one degree could lower energy demand by 10%. Employees are advised to use fans and prioritize public transit to reduce fuel consumption.
Meanwhile, the Philippines, which imports 98% of its oil from the Middle East, has cut government workdays to conserve power. Thailand has implemented remote work policies and urged residents to limit air-con use. South Korea, dependent on over two-thirds of its energy from the Gulf, encourages shorter showers and weekend laundry to save resources.
Regional Impact of the Energy Crisis
Ichiro Kutani of Japan’s Institute of Energy Economics described the economic fallout as the “Asian crisis.” Developing nations, particularly affected by petrol car proliferation and gas-dependent households, face severe strain. The crisis underscores the need for Asia to optimize oil usage and diversify energy sources, according to Kutani.
