Summary: This study analyzes the impact of urbanization on air pollution in China and finds that urbanization has both negative and positive effects on air quality, depending on the stage and policies of urbanization. From 2000 to 2012, urbanization had an impact on PM2.5 concentration, but the effects were mostly not significant from 2013 to 2019. After 2015, China's urbanization decoupled from PM2.5 concentrations.

Summary: The efficiency, flexibility, and resilience of building-integrated energy systems are challenged by unpredicted changes in operational environments due to climate change, while the rapid evolution of artificial intelligence and machine learning has equipped buildings with an ability to learn. Research has mainly focused on specific machine learning applications for different phases of a building's life-cycle, lacking a holistic perspective on the integration of smart technologies at the system level. Enhancing buildings' adaptability to unpredicted changes through AI-initiated learning processes and using digital twins as training environments can greatly improve energy efficiency at the level of HVAC control and electricity market participation.
