SINGAPORE: Around 10,000 more Build-to-Order (BTO)<\/span> households in Tengah will have the option of centralised cooling systems, the Housing & Development Board (HDB) and Keppel said in a joint media release on Thursday (Apr 16).<\/p>\n HDB awarded Keppel a 20-year contract to design, install and operate the systems at nine upcoming BTO projects, covering about 10,000 households in Tengah\u2019s Brickland, Park and Forest Hill districts.<\/p>\n This is Keppel\u2019s second such contract, bringing the total to about 14,000 households across 12 Tengah BTO projects with access to Keppel’s centralised cooling system.<\/p>\n The first contract was awarded in September 2024 and spans over 20 years, covering three Tengah BTO projects: Brickland Weave, Plantation Edge I & II, and Plantation Verge.<\/p>\n According to HDB and Keppel, centralised cooling systems are a more energy-efficient alternative to conventional air-conditioning, consuming 30 per cent less energy.<\/p>\n Instead of individual condensers, chilled water from centralised chillers is supplied to homes to cool the flats. Residents who opt in early can also have their air-conditioning ready by the time they collect their keys.<\/p>\n Mr Tan Sze Tiong, chief sustainability officer of HDB, said: \u201cHDB is committed to realising the vision of Tengah as Singapore\u2019s first and largest smart and sustainable HDB town.”<\/p>\n When completed, the centralised cooling systems across all 12 BTO projects will be linked to Keppel\u2019s operations nerve centre for remote control and real-time performance monitoring.<\/p>\n<\/div>\n
