On February 2 a ceremony was held to formally launch two buildings on the CDE campus – SDE1 and SDE3 - that have been redesigned and retrofitted with modern, low-energy green architectural elements. Together with the neighbouring SDE4 building, they form NUS’ first building cluster targeting net-zero. The event also saw the launch of NUS Cities, a new interdisciplinary centre based within CDE that aims to develop innovative solutions for sustainable, resilient and liveable cities by drawing upon expertise from across NUS to offer university-wide education and research programmes. Both initiatives were launched by Mr Heng Swee Keat, Deputy Prime Minister and Coordinating Minister for Economic Policies.
