The City Solar Map, titled “Sunny Hong Kong – Developing a Prototype of an Open Access, Big Data Driven, Online Solar Map through Multi-sector Partnerships”, enhances public access to solar energy data. It aims to establish a multi-sectoral consortium (NGOs, schools, private sectors, households) to develop an advanced solar map, visualize solar PV performance and carbon reduction, and educate communities through firsthand solar owner stories. Additionally, it identifies challenges in building an open, shareable data platform and explores solutions. This initiative promotes transparency, awareness, and adoption of solar energy for a more sustainable urban future.

City Energy Map, titled “Asian-European Cities Online Energy Map”, is an interactive platform designed to visualize, track, and monitor energy-saving hotspots in selected case communities across Hong Kong and other Asian-European cities. This map provides a comprehensive overview of urban energy consumption patterns, helping researchers, policymakers, and the public identify trends, best practices, and areas for improvement. By integrating real-time data, spatial analysis, and community engagement, the platform aims to support sustainable urban development, enhance energy efficiency, and promote the adoption of low-carbon solutions.
