Deep underneath Singapore’s northeastern district of Punggol, a five-kilometre network of metal pipes roars as it pumps chilled water to cool offices and classrooms overhead. The 140-year-old concept known as district cooling is taking root in the island-nation, where temperatures are rising twice as fast as the global average and sharpening the focus on climate adaptation. That the old technology uses less electricity than centralised air conditioners is a major advantage for a resource-starved country that has to import nearly all its energy. The city-state has laid such pipes beneath at least eight neighbourhoods so far, with the Marina Bay network – the world’s largest underground system – having begun operations in 2006. More buildings will be linked up to that system, and separate facilities are being rolled out in other parts of the city by firms such as Keppel EaaS.   https://www.businesstimes.com.sg/esg/singapore-brings-back-19th-century-tech-beat-warming-climate (ICE SINGAPORE)
