Summary
The rapid transition toward low-carbon and sustainable development requires intelligent energy engineering solutions that can simultaneously improve energy efficiency, industrial productivity, environmental quality, and system resilience. The integration of artificial intelligence, advanced modelling, smart sensing, digital technologies, renewable energy, and sustainable engineering is creating new opportunities to address increasingly complex energy and environmental challenges. In this context, intelligent energy systems can support real-time monitoring, predictive analysis, optimization, and autonomous decision-making across industrial and environmental applications.
This Special Issue, "Intelligent Energy Engineering for Sustainable Industrial and Environmental", aims to provide a multidisciplinary platform for researchers and practitioners to present innovative technologies, methodologies, and applications that integrate intelligent systems with sustainable energy and environmental engineering. Contributions addressing theoretical developments, experimental investigations, numerical modelling, artificial intelligence, and practical industrial applications are particularly encouraged.
Suggested themes include, but are not limited to:
· Intelligent and renewable energy systems
· AI and machine learning for energy optimization
· Energy-efficient HVAC and sustainable built environments
· Smart environmental monitoring and air-quality management
· CFD, digital twins, and intelligent modelling
· Industrial energy efficiency and decarbonization
· Sustainable manufacturing and Industry 4.0
· Vibration, condition monitoring, and intelligent mechanical systems
· Waste-to-energy and circular economy technologies
· Hydrogen, alternative fuels, and low-carbon energy technologies
· Integrated energy–environment systems and sustainable engineering
