Kärnskalverk

Kärnskalverk is a term of Swedish origin that translates to "core shell structure" or "core scale work." It describes a specific architectural or engineering concept where a central, robust core is encased by a lighter, outer shell. This design principle is often employed to optimize structural integrity, efficiency, and material usage.

The core typically houses essential functions or structural elements, such as stairwells, elevator shafts, or primary load-bearing components. Its solidity provides stability and resistance to external forces. The outer shell, in contrast, is designed to protect the core and enclose the habitable or functional spaces. This shell can be made from a variety of materials, often lighter than those used for the core, and can be adapted to meet aesthetic or environmental requirements.

This approach allows for flexibility in the design of the spaces between the core and the shell. It can facilitate open-plan layouts or the integration of specialized systems. Kärnskalverk can be observed in various constructions, from high-rise buildings seeking enhanced wind resistance to other structures where a distinction between central support and peripheral enclosure is beneficial. The concept emphasizes a clear division of structural responsibility and functional arrangement.
