Which of the following systems supplies essential services like heat and electricity in a building?

The correct response highlights the role of building service systems, which are crucial for delivering essential services that ensure the functionality and comfort of a building. These systems encompass various components and mechanisms responsible for providing utilities such as heating, cooling, electricity, plumbing, and ventilation.

Building service systems integrate technology and infrastructure to support the comfort and safety of occupants. For example, heating systems may include furnaces or boilers that provide warmth, while electrical systems consist of wiring and fixtures that supply light and power to the building. This category also includes systems for water supply and waste management, all of which are integral to a building's operation.

On the other hand, other options such as the building envelope, substructure, and superstructure serve different functions. The building envelope refers to the exterior components that protect a building from weather and environmental elements, like walls, roofs, and windows. The substructure refers to the part of the building below ground level that provides support and stability, including foundations and footings. The superstructure consists of everything above the foundation, including walls and roofs, primarily concerned with the physical structure rather than utility services.

Thus, building service systems are essential for providing the utilities needed for modern living and ensuring that a building remains habitable and efficient
