Buildings are major global energy consumers, accounting for 20%–40% of total energy use in developed nations, exceeding industrial and transport sectors. This rising consumption, caused by population growth, higher living standards, and pervasive energy-intensive technologies, underscores the urgent need for enhanced energy efficiency in the built environment. These measures are vital for environmental sustainability, societal well-being, and balanced development.Reducing building energy demand is both an environmental and societal challenge, requiring a holistic approach. This includes energy efficiency, renewable energy adoption, and occupant behavioural changes, balancing technical and societal challenges to achieve net-zero aspirations. Achieving net-zero aspirations demands collaboration among stakeholders, including governments, developers, and building occupants. We invite contributions on the role of buildings in urban energy reduction, focusing on services technologies, new design initiatives, and AI in building management. The importance of existing building archetypes and their potential for energy demand management through efficient envelopes and technological advances is also a key consideration. We welcome various formats, including literature reviews, research papers, and case studies, that use both quantitative and qualitative data to analyse pilot projects, stock modelling, or city-scale proposals.
