The central core of a skyscraper typically houses elevator shafts and mechanical systems, which are crucial for the functionality and operation of the building. This area is designed to efficiently transport passengers and goods between floors, particularly in high-rise structures where vertical movement is essential.

The inclusion of mechanical systems within the core enhances building performance, as these systems often include HVAC (heating, ventilation, and air conditioning), electrical lines, and fire safety components. Centralizing these utilities within the core not only optimizes the use of space but also provides easier access for maintenance and ensures structural integrity by keeping the load-bearing walls intact.

In contrast, dedicated parking facilities and utilities like plumbing are usually located in separate areas away from the core to maximize space and convenience for tenants and visitors. Likewise, while art installations may contribute to the aesthetics of a skyscraper, they do not belong to the functional and operational components that reside in the central core.
