In Singapore, rising temperatures are not just a feeling; they are a reality many residents face daily. The latest episode of the Business Times podcast, “Lens on Singapore,” hosted by Howie Lim, delves into the challenges of staying cool in the city-state, especially amidst escalating energy costs due to factors like El Niño.

As temperatures climb, many Singaporeans find themselves relying more on air conditioning, leading to increased electricity bills. James Trevelyan, emeritus professor at the University of Western Australia’s Engineering School, emphasizes the global rise in energy costs, citing examples like Italy and Pakistan, where electricity prices have surged. He introduces his invention, Coolzy—a portable, energy-efficient cooling solution designed for targeted comfort at home. While modern air conditioning systems are more efficient than older models, they still demand significant electricity, underscoring the need for additional cooling strategies.

Shopping malls in Singapore, popular as cool retreats, are adopting sustainable practices to manage their energy consumption. For instance, the Paragon mall has made modifications to its chiller and air-handling units, achieving a 30% reduction in energy use, as noted by CEO Susan Leng. This commitment to sustainability extends to residential developments, where cooling solutions are integrated into design elements. Janice Wu from Cuscaden Peak Investments highlights the use of strategic building materials and greenery to enhance natural cooling.

On a larger scale, district cooling initiatives, such as those in the Marina Bay area, have significantly reduced carbon emissions—equivalent to removing 22,000 cars from the roads annually. Suaw Ching Yi of SP Group outlines how centralized cooling systems benefit closely situated buildings in Singapore, with plans for further implementation in new developments like the Tengah township.

For residents looking to stay cool without straining their finances, Professor Lee Poh Seng offers practical tips, such as utilizing fans for air circulation and opening windows for natural ventilation when possible. Using shades, blinds, or curtains to block sunlight during peak hours and wearing lighter colors can also enhance comfort.

Additionally, promoting telecommuting can help alleviate cooling demands in office spaces. Sebastien Walker from Engie South-east Asia emphasizes that sustainable living choices—like selecting energy-efficient buildings or opting for electric vehicles—can collectively contribute to a healthier environment and combat the climate crisis.

In summary, as Singapore grapples with rising temperatures and energy costs, a combination of sustainable practices and individual choices can play a crucial role in maintaining comfort and minimizing expenses.
