Congratulations to the PolyU LSGI student - Mr. TONG Lai Yiu Jimmy has won the Esri Young Scholars Award 2025 (Individual Application). The Eris Young Scholars Award 2025 is a competition aimed at recognising exemplary work in geospatial sciences and the creative use of applications for a smarter Hong Kong.
The awarded project titled “Assessing Rooftop Solar Energy Potentials in Hong Kong” aims to enhance rooftop solar energy assessment in Hong Kong by developing a GIS-based framework and algorithms to improve the accuracy of estimation models. It investigates the spatial-temporal patterns of solar energy potential across different districts and land-use categories, as well as the influence of cloud cover on solar radiation received by rooftops.
Additionally, the research explores the relationship between rooftop solar energy potential and urban building morphology, including factors such as building density, height, and roof area. It also evaluates the benefits of rooftop solar energy in terms of energy savings, carbon reduction, and economic value.
The findings indicate that over 90% of rooftop solar projects yield profitable returns, with more than 60% achieving an economic payback period of six years. This research provides valuable insights for promoting green building and sustainable development in Hong Kong.
Congratulations on this remarkable achievement, contributing to a sustainable future through innovative research!
