An electrical shaft in architecture is a vertical space or conduit designed to house electrical wiring, cables, and related utilities within a building. These shafts provide a safe and organized pathway for electrical systems, ensuring efficient distribution of power, data, and communication lines across multiple floors.
Typically enclosed within walls or dedicated service cores, electrical shafts help in maintaining the building’s aesthetics while protecting wiring from external damage, fire hazards, and unauthorized access. They are strategically placed to minimize energy loss, facilitate maintenance, and comply with building codes and safety regulations.
In high-rise buildings, electrical shafts often integrate with mechanical and plumbing shafts to optimize space and infrastructure planning.
