The two-volume set LNCS 16981 + 16982 constitutes the proceedings of the 6th Energy Informatics Academy Conference, EI.A 2026, which took place in Beijing, China, during October 14, 2026.

The 41 full papers and 13 Short papers included in the proceedings were carefully reviewed and selected from 77 submissions. They focus on a unique perspective on how digitalization is transforming the technical, economic, and societal dimensions of modern energy systems.  They were organized in topical sections as follows:

Part I: Flexibility, Forecasting and Supply in District Heating; Digital Transformation of Buildings into Active Energy Prosumers; HVAC, Thermal Comfort and Building Energy Performance; Trustworthy Data and Language Models for Energy Systems; 

Part II: Probabilistic Forecasting and Decision-Making under Uncertainty; Data- and AI-Driven Energy–Climate–Economy Modeling for Mitigation–Adaptation Transitions; Industrial Systems Under Climate and Energy Uncertainty: Adaptation Readiness, Energy Resilience, and Digital Intelligence; Grid Resilience, Energy Storage and Electric Mobility; From Living Labs to Virtual Testbeds: Experimentation and Validation in Energy Informatics.
