DoRILS honoured by National Natural Science Foundation of China

Prof. Xiaoli DING, Director of the Research Institute for Land and Space and Chair Professor of Geomatics, has been awarded under the National Natural Science Foundation of China (NSFC) Key Programme 2023.   Project title: Detection of underground water pipe leakage based on multi-temporal PolInSAR technology   Abstract: Leakage from underground water pipes is a very common phenomenon internationally. According to statistics, water pipe leaks cause most cities to lose about 30% or more of freshwater resources, leading to huge resource and economic losses. The lack of effective water pipe leakage detection technology is one of the main reasons. Water supply pipelines are mainly buried below the ground surface. It is therefore difficult to detect pipeline leakage in time. Long-wave polarimetric SAR signals (such as L or P-band) are able to penetrate the ground surface and objects and can record subsurface water content information, which provides an important opportunity to solve the problem of water pipe leakage detection. However, research in this area is still very limited. For example, the relationship between polarimetric SAR signals and subsurface water content is still unclear. The influence of ground surface, buildings and vegetation on polarimetric SAR signals still needs further research. This project will conduct in-depth research on the use of polarimetric SAR for underground water pipe leakage detection, including 1) separating the scattering signals related to subsurface water from the polarimetric SAR signal; 2) establishing the relationship between the polarimetric SAR dielectric parameters and the leakage process 3) modeling the dielectric parameters of urban hardened surface and subsurface separately. The research will help to break through the technical bottleneck of underground water pipe leak detection and make an important contribution to saving precious freshwater resources.   Big congratulations to Prof. Ding!   Online coverage (Chinese only): Ta Kung Pao - https://polyu.me/45WNVBt Wen Wei Po - https://polyu.me/3PDxDHQ

PolyU startup pilots radiative cooling coatings to combat heat in building structures

A PolyU startup co-founded by Prof. DAI Jianguo, Management Committee Member of the Research Institute for Land and Space (RILS), initiated pilot schemes to apply “UmiCool”, a sub-ambient cooling coating developed by the team, to various building structures in Hong Kong and mainland China, hence achieving cooling and energy saving effects and reducing the reliance on air conditioning. The UmiCool coating uses patented fluorescent cooling technology and can be painted onto the exterior walls of buildings to effectively reduce indoor temperature. Umicool absorbs UV radiation in the sunlight and converts it into infrared radiation for re-emission. It can reach up to 97% in solar reflectance, and can lower the indoor temperature by up to 4 degrees Celsius. The start-up co-founded by Prof. Dai, Umi Coating New Material Technology Co., Limited, collaborated with the Electrical and Mechanical Services Department and the Home Affairs Department of the HKSAR, to conduct pilot projects in applying UmiCool to building structures in Tung Chung and Mui Wo in Lantau Island, as well as rooftops of squatter huts in Pokfulam villages, respectively. This technological innovation was awarded several international patents and won a Gold Medal in the 2022 Geneva Inventions Expo. The startup is planning to establish a sales and production base in Foshan, Guangdong to expand its business in the Greater Bay Area. In the future, the company will expand its technology to other regions and encourage individuals to adopt environmentally friendly and energy-saving coatings.   Online coverage: EJ Tech – http://ejtech.hkej.com/?p=138427  

RILS scholar finds causes for wild weather swings from drought to flood

A collaborative study by Dr WANG Shuo, Member of the Research Institute for Land and Space (RILS) and Associate Professor of the Department of Land Surveying and Geo-Informatics (LSGI), Miss QING Yamin, PolyU doctoral student, and researchers from the University of Texas and Columbia University, found that wild weather swings from severe drought to heavy rains are becoming more common with climate change, based on analysis on climate data during 1980–2020. The team also discovered the “land-based feedback loops”, which explains how the movement of moisture from humid regions to dry regions increases the chance of downpours after drought. These results can be useful to help increase the accuracy of predictive climate models and help communities to better prepare for swings between drought and flooding.   The study has been published in Communications Earth & Environment https://www.nature.com/articles/s43247-023-00922-2   Online coverage: Yahoo UK - https://polyu.me/45x6Faq  

ADoRILS releases interim findings of Study on Effective Transitional Housing Delivery in Hong Kong with multiple policy recommendations

Prof. K. K. LING, Associate Director of Research Institute for Land and Space (RILS) and Director of Jockey Club Design Institute for Social Innovation, and his team released the interim findings of “Study on Effective Transitional Housing Delivery in Hong Kong” and its report on policy recommendations. Funded by the Strategic Public Policy Research Funding Scheme of the HKSAR government, the Study is the first comprehensive study of Hong Kong’s transitional housing programme.  The Government plans to complete 84 transitional housing projects and provide over 21,000 housing units by 2024–25, among which over half are in the New Territories. The Study examined 35 Modular Integrated Construction (MiC) housing projects at open-air sites, which provide about 86% of transitional housing (TH) units delivered under the programme. The Study concluded that Hong Kong’s TH programme, as compared to the relocatable modular building projects in other cities, has the largest scale, fastest construction speed and widest societal participation. The Study supports the Government for taking up the role of builder in the Light Public Housing (LPH) programme to enhance the efficiency of housing delivery, and makes the following recommendations: Recognise the function and position of TH Integrate TH and LPH Standardise the design of MiC units Assist tenants to settle down in the Northern Metropolis Engage NGOs in the community-building of LPH development Advance planning on the re-use of MiC units   Read the full study: https://polyu.hk/nnJYh   Online coverage: RTHK “Hong Kong Today” - https://polyu.me/47EoNR4 (31:28 – 41:35) RTHK - https://polyu.me/3OBcAUR Commercial Radio - https://polyu.me/3OHZaq8 Oriental Daily News - https://polyu.me/3qDEpnt Ming Pao Daily News - https://polyu.me/3KLPYzX; https://polyu.me/3YDrluO Hong Kong Economic Times - https://polyu.me/3OZRMaL Sing Tao Daily - https://polyu.me/3OWTsSt am730 - https://polyu.me/3QJpBOQ Wen Wei Po - https://polyu.me/3qEPqov; https://polyu.me/3P13X7r HK01 - https://polyu.me/3YEqCJS
