Scope
Aims, scope and focus
Spool is published by Technische Universiteit Delft/Delft University of Technology.

(generated from OpenAlex topic counts and CAS ranking data)
SPOOL is a journal initiative in the field of architecture and the built environment. It places strong emphasis on four key topics: Science of Architecture, Landscape Metropolis, Energy Innovation, and Cyber-physical Architecture. These four topics reflect existing and emerging research programs and interests in Europe and beyond, ensuring a steady stream of potential contributions. By treating these topics as interconnected threads within a single journal, SPOOL is able to focus on the relationships between these fields—connections that are often overlooked in more specialized journals. Within this framework, SPOOL welcomes original papers and associated open data on research addressing interventions in architecture and the built environment through design, engineering, and/or planning.
