Hot in the city: Energy crisis tests Singapore’s air-con addiction

In response to soaring energy costs linked to the Iran conflict, Singapore has mandated that government employees raise office temperatures to a minimum of 25C (77F). This measure aims to reduce reliance on air-conditioning, which has become a key factor in the city-state’s struggle with elevated fuel prices. To support these efforts, public buildings will also adopt energy-efficient upgrades, such as LED lighting and smart sensors, to cut overall consumption.

The move aligns Singapore with other Southeast Asian nations implementing similar conservation strategies. Thailand, for instance, has urged public sector workers to maintain air conditioners at 26-27C. The region’s dependence on oil and gas supplies through the Strait of Hormuz, a critical shipping route, has intensified the need for energy-saving initiatives as tensions disrupt global fuel networks.

A legacy of cooling

“The first thing I did upon becoming prime minister was to install air conditioners in buildings where the civil service worked. This was key to public efficiency.”

– Lee Kuan Yew, Singapore’s founding father, who attributed the country’s modernization to air-conditioning. His vision enabled tropical workers to thrive indoors, despite extreme outdoor conditions. Yet, as energy prices climb, the city-state now faces the challenge of balancing comfort with sustainability.

Today, nearly all offices in Singapore are equipped with air-conditioning, though some critics argue its use has become excessive. Employees often wear cardigans or sweaters during work hours, a habit stemming from the consistently low temperatures maintained in workplaces. Malls and department stores, unlike open-air shopping streets in other parts of Southeast Asia, are fully climate-controlled, creating a stark contrast for pedestrians entering these spaces.

Public transport in Singapore, including buses and trains, also relies on air-conditioning. While this ensures passenger comfort, it adds to the city’s energy demand. Most households have air-conditioning units, many of which run continuously, contributing to the nation’s overall consumption. The Ministry of Sustainability and the Environment emphasized that raising the temperature by one degree can cut energy needs by approximately 10%, urging both workers and businesses to adapt.

A regional ripple effect

As fuel prices surge, governments across Asia are taking action. The Philippines, which sources 98% of its oil from the Middle East, has reduced the workweek for public offices. Thailand has ordered staff to work remotely and limit air-con usage to 26-27C, while South Korea encourages shorter showers and weekend laundry to ease pressure on energy supplies.

Ichiro Kutani, from Japan’s Institute of Energy Economics, described the economic fallout of the Iran war as the “Asian crisis.” He noted that developing nations, particularly those with high numbers of petrol vehicles and gas-dependent households, are bearing the brunt of disruptions. In the long term, Kutani warned, the crisis would force Asia to prioritize oil efficiency and diversify its energy sources.

Singapore, which imports about two-thirds of its crude oil from the Middle East, has not yet depleted reserves or introduced rationing. Nonetheless, the nation is actively leading efforts to curb energy use, as highlighted by its recent initiatives. The city-state’s unique approach underscores the delicate balance between its air-conditioning-driven lifestyle and the urgent need for conservation in a volatile energy landscape.
