UTown is a high-density precinct at the National University of Singapore's main campus that was completed in 2016. It was designed and constructed over 10 years according to sustainable development principles. UTown integrates learning, living, and discovery spaces and is certified as a Green Mark district, with all buildings certified and over half achieving the highest platinum status. The precinct employs various strategies to promote energy efficiency, water efficiency, environmental protection, and waste management. These include building orientation for solar access, extensive use of natural ventilation, LED lighting, green roofs, rainwater harvesting, and a district cooling system. UTown fosters sustainability through exhibitions, bicycle facilities, and a virtual model to aid ongoing master planning and operations.

Editor's Notes
- Number of buildings on the main campus has gradually increased over the years on an as-needed basis to accommodate the growing student and staff population UTown was a unique opportunity for NUS to create from scratch a sustainably designed, built, and operated precinct, at such a scale for the very first time Objective was to co-locate various teaching, research and residential facilities for a new and more holistic learning experience but also a more vibrant student life
- Extension of the main Kent Ridge campus of NUS, comprising: Education Resource Centre – an educational hub replete with IT and multimedia facilities, study clusters and group discussion spaces, as well as technology-infused seminar rooms Stephen Riady Centre – Sports complex Yale-NUS college, Asia’s first liberal arts college Research and development complex (CREATE) – set up by the National Research Foundation, an international collaboratory of research centres
- First-of-its-kind precinct with natural and mixed-mode ventilation to be built for a tropical climate Allowed for design and planning of a low carbon precinct (versus piecemeal additions) with respect for natural resources during the planning and construction phases, as well as in its operations
- Design of buildings positioned in north-south directions to reduce exposures of interiors to direct sunlight, and minimise cooling loads Allowed the University to build the first district cooling plant for a tertiary institution due to the scale of the development, as opposed to individual cooling facilities for one or a few buildings Major circulation areas within and in between buildings were designed to be naturally ventilated as far as possible, without sacrificing human comfort in the tropical heat and humidity
- Large town green provides cross ventilation of prevailing north south winds while enhancing the cooling effects of conserved trees Green roofs – comprising about 7.6% of the campus area, the green roofs reduce heat drawn, decreasing the amount of energy needed to cool the buildings; used to cleanse storm water as it filters through the plant and soil. A portion of the rainwater is then used to water campus plants Use of innovative cooling technology such as chilled beams and under-floor cooling; first to be tested on campus Recycled materials were used in parts of the construction of UTown, such as the walls of an auditorium and the timber decking of the Education Resource Centre’s first level foyer
- Integration of the built and natural environment was a key consideration in the design and planning of UTown Rolling terrain of the original site and its natural biodiversity were preserved as much as possible. A biodiversity study was conducted during the planning stage to account for total number of indigenous plant and animal species. Roads were designed around trees and building features to incorporate existing Tembusu heritage trees in inner courtyards Existing green buffer around UTown was retained and left wild to encourage growth of the natural habitat for flora and fauna
- Being sustainably designed, built and operated, UTown serves as a living backdrop and a daily reminder to the students on the sustainability agenda and nature conservation Sustainability messaging and events at UTown reminds students of its green features, encouraging them to be more aware of the environment and to conserve natural resources Pay-per-use scheme for air conditioning: hostel rates at residential areas in UTown are not inclusive of utilities charges for air-conditioning; separate charges are applicable, contributing to lower electricity usage A covered link bridge connects UTown to the main campus, allowing students and staff to walk, bike, rollerblade or even skateboard between the campuses. To encourage students and staff to ride their bikes and walk on campus, UTown has an interior network of sheltered walkways and dedicated bicycle lanes. Access for vehicles is limited to a ring road to enhance the pedestrian-friendly environment All residence buildings have ample bike storage facilities
