Prof. WENG Qihao, Associate Director of the Research Institute for Land and Space (RILS), Member of the Otto Poon Charitable Foundation Smart Cities Research Institute (SCRI) and Chair Professor of Geomatics and Artificial Intelligence, and his research team studied the energy-saving potential of green roofs and cool roofs in reducing building energy consumption. The paper was published in the journal npj Urban Sustainability.
The study evaluated the green roof and cool roof strategies in six global cities, including Cairo, Hong Kong, Seoul, London, Los Angeles, and Sao Paulo, under current and future climate change scenarios. Results showed that in future climates, the implementation of these strategies at the city level can lead to up to 65.51% annual energy reduction and 71.72% reduction in Heating Ventilation and Air Conditioning (HVAC) consumption by 2100. These findings can guide the implementation of these strategies in different climatic zones worldwide, informing the selection and design of suitable roof mitigation strategies for specific urban contexts.
