Nationwide Rollout Follows Successful Pilot Reducing Temperatures by Up to 2°C
Singapore will extend the use of heat-reflective paint to all Housing Board (HDB) estates by 2030, following a successful pilot in Tampines that reduced ambient temperatures by up to 2°C. Senior Minister of State for National Development Tan Kiat How announced that the initiative, part of the Green Towns Programme, will require an additional SGD 60 million (USD 43.8 million) and aims to enhance sustainability in public housing amid growing urban heat challenges.
Launched in 2020, the Green Towns Programme is a 10-year sustainability initiative designed to make Singapore’s public housing towns cooler, greener, and more energy-efficient by 2030. It includes heat-reflective paint, smart electrical sub-meters, solar panels, and waste reduction strategies to tackle climate change and improve urban living conditions.
Heat-Reflective Paint Initiative
Following a successful two-year pilot in Tampines, where cool coatings were applied to 130 HDB blocks, the government will roll out this initiative nationwide. The paint’s special additives reflect solar heat, reducing surface heat absorption and lowering ambient temperatures by up to 2°C, which also helps reduce household electricity consumption.
SGD 60 Million Investment
Expanding the project to all HDB estates will require an additional SGD 60 million investment. This reflects Singapore’s long-term commitment to sustainable urban living and efforts to reduce the urban heat island effect in densely populated areas.
Smart Energy Monitoring
Starting in the second quarter of 2025, HDB blocks will be fitted with smart electrical sub-meters to track energy consumption patterns. These meters will help town councils optimize maintenance schedules, monitor equipment performance, and detect anomalies such as equipment faults to reduce downtime.
Broader Sustainability Efforts
Beyond heat-reflective paint, the Green Towns Programme includes solar panel installations, electric vehicle (EV) charging stations, and the deployment of machines that convert food waste into compost. By 2030, 38 HDB-managed complexes will be upgraded with energy-saving technologies, targeting a 10% reduction in both energy and water consumption.
Community Engagement and Impact
Community gardens, green rooftops, and recycling programs are being integrated into HDB estates to promote eco-friendly living. Residents, such as 65-year-old Doreen Koh from Woodlands, highlight the social benefits of these initiatives, which foster community spirit and contribute to environmental sustainability.
These initiatives promise cooler living environments, lower energy costs, and a greener urban landscape. International visitors will experience Singapore’s commitment to sustainability firsthand, reinforcing the city-state’s reputation as a global leader in eco-friendly urban development.
