PolyU researchers unveil novel carbon dots-driven green radiative cooling coating for energy saving in buildings

Buildings account for about 90% of Hong Kong ’ s electricity consumption and over 60% of carbon emissions. Energy conservation in buildings is crucial for achieving climate mitigation goals. The Hong Kong Polytechnic University (PolyU) researchers have developed an environmentally friendly solar-driven adaptive radiative cooling (SARC) coating for building roofs and walls. This coating can reduce a building’s surface temperature by up to 25°C and lower indoor temperatures by 2 to 3°C, all without consuming any energy. This non-toxic, metal-free and durable coating can be produced on a large scale, promoting an eco-friendly and energy-saving method to mitigate urban heat island effects and support the achievement of carbon neutrality. Coating a building in a reflective material enablesthe self-regulation of its thermal environment to minimise indoor temperatures. However, traditional passive radiative cooling materials are unable to automatically adjust cooling capacity in response to environmental changes, which limits their applications. To address this challenge, a research team led by Prof. LU Lin Vivien, Professor of the Department of Building Environment and Energy Engineeringat PolyU, along with key team member Dr Quan GONG, Postdoctoral Fellow of the same department, has invented a carbon dots(CDs)-driven SARC coating that can adjust cooling capacity based on solar irradiance. This new photoluminescent radiative cooling nanocoating can convert solar energy into light energy. As solar intensity increases, the coating’s solar reflectance is enhanced, preventing buildings from absorbing excessive heat. However, traditional photoluminescent cooling materials typically rely on rare earth metals and perovskite materials, which pose environmental risks.To address these issues, Prof. Vivien Lu’s team has introduced groundbreaking, environmentally friendly polymer-based CDs as photoluminescent materials into radiative cooling coating. Nano-sized CDs were embedded into polymers to create a biologically harmless material. The polymer CDs were uniformly coated onto hollow glass particles to create Smart Cooling Beads, enabling the coating to effectively convert ultraviolet light into visible light photons and increase effective solar reflectance. This water-soluble SARC only requires the evaporation of water to form a coating on building surfaces without releasing any volatile organic compounds, thereby reducing air pollution. Results have shown that, compared to conventional radiative cooling coating, the new SARC coating improved effective daytime solar reflectance from 92.5% to 95% and increased the cooling effect by 10% to 20%. For example, it can reduce the temperature by up to 25°C when applied to concrete rooftops. In a demonstration project with the HKSAR Government department, the team applied the SARC coating to the roofs of container houses at a construction site in Hong Kong. After approximately two and a half years of continuous outdoor exposure, the coated roofs remained 24 °C cooler than concrete roof under sunlight. The coating proved highly durable, with solar reflectance decreasing by less than 2% over the two-year period. Annual energy savings of 10% were achieved by reducing the air-conditioning load. By mapping the average annual temperature drop and cooling power across different climatic regions of Mainland China, the team observed that the stronger the radiation, the greater the temperature difference the new SARC coatingachieved. Taking as examplesHong Kong and 10 Mainland cities—Beijing, Hangzhou, Guangzhou, Changsha, Hotan in Xinjiang, Shenyang, Guilin, Fuzhou, Chongqing and Lanzhou—the adoption of this novel cooling coating for buildings is projected to save between 97 and 136 kWh/m² of electricity annually in each city. Prof. Vivien Lu remarked, “As global warming intensifies and extreme weather events like heatwaves become more frequent, the scientific community is increasingly focused on finding ways to cool buildings while minimising energy consumption. Our novel SARC coating demonstrates exceptional cooling performance and is suitable for a wide range of climates, thereby accelerating the development of next-generation cooling materials. This water-soluble coating can also be produced in various colors, allowing it to be easily applied to building roofs, walls, roadways, and urban surfaces, using paint rollers.It achieves both cooling and aesthetic enhancements and offers a promising solution for sustainable urban development and mitigating the urban heat island effect.” With support from PolyU’s Carbon Neutrality Funding Scheme, the team has also integrated the photoluminescent coating with bifacial solar photovoltaics (PV) to achieve synergistic enhancement in thermal management and power generation, transforming buildings from energy consumers into energy harvesters. The team is planning to install bifacial PV panels on the rooftops of the under-construction PolyU Kowloon Tong Student Hostel, with new coating applied on the corresponding area under the panels, to enhance power generation while radiatively cooling the buildings. The team expects this dual-functional system to improve electrical power generation by 30-50% and reduce the carbon emission by 30% compared with conventional uncoated rooftops. Taking this project as an example, installation of PV over an area of approximately 600 m2 on hostel rooftops can generate 97,000 kWh of electricity, resulting in annual cost savings of over HK$120,000. The team is also developing a paraffin-based self-adaptive radiative cooling coating that can maintain appropriate solar reflectivity in response to cold and hot weather, achieving the effect of keeping warm in winter and cooling in summer. The water-soluble SARC coating can also be produced in various colours, allowing it to be easily applied to building roofs, walls, roadways, and urban surfaces to achieve both cooling and aesthetic enhancements.

PolyU scientist’s breakthrough energy-efficient innovations in applications for sensory AI systems

Prof. Yang CHAI, Associate Dean (Research) of the Faculty of Science and Professor of the Department of Applied Physics at The Hong Kong Polytechnic University (PolyU), has conducted groundbreaking research on sensory artificial intelligence (AI), paving the way for more energy-efficient, low-latency and memory-optimised AI systems. His advancements significantly enhance diverse applications such as mobile devices, IoT sensors and edge computing. Overcoming crucial barriers in power consumption, latency and memory within sensory AI systems, Prof. Chai’s innovations unleash the potential of sensory AI across diverse industries and domains. Furthermore, the in-sensor computing strategy has sparked progress in improving decision-making and situational awareness, strengthening privacy and security, and transforming intelligent automation. For his exceptional innovation, Prof. Chai has been honoured as a 2024 Falling Walls Winner in the Engineering & Technology category for “Breaking the Wall of Efficient Sensory AI Systems”. He has developed novel hardware architectures and optimisation techniques, which enable the deployment of advanced sensory AI systems in mobile devices, IoT sensors and edge computing, subsequently transforming applications in smart cities, autonomous vehicles and industrial automation. The Falling Walls Science Breakthroughs of the Year Award was initiated by the Berlin-based Falling Walls Foundation, to recognise the latest breakthroughs and outstanding science projects worldwide. This year, the jury, comprising globally recognised experts in the various fields, reviewed over 1,000 entries from 52 countries. In the Engineering & Technology category, 10 excellent winners were selected and shortlisted for the award of Science Breakthrough of the Year 2024. Prof. Chai said, “The proliferation of data from ubiquitously distributed sensors leads to a massive increase in sensory terminals. It is crucial to partially shift computation tasks to the sensory terminals. This transition substantially compresses the collected information and extracts key data, especially for sensor-rich platforms.” Prof. Chai’s research clearly defines near-sensor concepts and in-sensor computing paradigms based on the physical distance between sensory and computing units. This classification further divides functions into low-level and high-level processing. His study explores the implementation of near-/in-sensor computing for different physical sensing systems and provides possible solutions for integrating sensing and processing units through advanced manufacturing technologies. While Prof. Chai and his team focus on advancing computational hardware for sensory AI systems, the extraordinary capabilities of natural bioinspired sensory systems more broadly are a vital research inspiration. By emulating human visual adaptability, which allows accurate object identification under various lighting conditions, the new bioinspired sensors developed by Prof. Chai’s team offer a solution for the progress in motion processing by directly adapting to different light intensities. This approach avoids relying solely on backend computation, which emulates and even surpasses the human retina’s ability to adapt to various lighting levels. The sensors reduce hardware complexity and boost image contrast in varied lighting conditions, thus improving machine vision systems for visual analysis and identification tasks. Inspired by flying insects’ high flicker function frequency, Prof. Chai has pioneered research on optoelectronic graded neurons for perceiving dynamic motion. This innovation efficiently encodes temporal information at sensory terminals, reducing the amount of visual data transferred relating to fusing spatiotemporal (spatial and temporal) information in a computation unit. This advances machine visual systems with minimal hardware resources, promising potential applications in autonomous vehicles and surveillance systems. These outstanding findings have been published in high-impact journals including Nature Electronics and Nature Nanotechnology, and have been highlighted in Nature, IEEE Spectrum and others, while also being highly cited by research teams worldwide. He envisions, “My long-term goal is to develop cutting-edge microelectronic and nanoelectronic devices with new functionalities and unprecedented performance. Specifically, we intend to create imaging technology capable of perceiving three-dimensional depth, four-dimensional spatial-temporal and multiple spectral (beyond visible light) information. To achieve this, a bio-inspired mechanism will be utilised to reduce power consumption and latency.” Learn more about Prof. Chai’s research focus in the video: https://www.youtube.com/watch?v=Lk7Rga3kSoc
