Chinese urban underground
spaces are rich in resources and offer significant development potential. The
exploitation and utilization of these spaces can enhance resource utilization
efficiency, ease traffic congestion, and increase urban green spaces, thereby
addressing the challenges associated with low-carbon urban development. First, the state of low-carbon development in urban underground spaces is reviewed.
Furthermore, the research and implementation of low-carbon
technologies in the development and utilization of underground spaces are
examined, focusing on the design, construction, operational strategies, use of
renewable energy resources, and underground stored energy. Second, challenges
encountered in the low-carbon development of urban
underground spaces, such as inadequate planning and construction coordination,
relatively extensive construction practices, and outdated concepts in operation
and maintenance management, are identified. Third, various strategies and
suggestions for low-carbon development are proposed,
including promoting integrated low-carbon development
and utilization; enhancing policies, regulations, and management systems of low-carbon development; and strengthening research and application of
low-carbon technologies in urban underground spaces.
Finally, the concept of a "zero-carbon underground
city" is introduced, including underground infrastructures of complexes,
utility tunnels, metro systems, and energy systems for photovoltaic power
generation, energy storage, thermal energy, and carbon reduction or even
negative carbon. These initiatives will enhance the economic, environmental,
and social advantages of underground space exploitation and utilization, thus
realizing Carbon Peaking and Neutralization Policy.
