Buildings, as significant contributors to carbon emissions, hold immense potential for analyzing the existing energy management system and implementing low-carbon strategies in their design, construction, operation, and maintenance. The objective of this project is to pioneer innovative smart retrofitting solutions geared towards the existing housing infrastructure, thereby reducing building carbon footprints and enhancing energy efficiency. This project would signify a significant step towards low-carbon building renovation and substantial energy conservation, contributing to a more sustainable building decarbonization and mitigating the impact of climate change.
