What systems are included under the category of electrical in building design?

The category of electrical systems in building design encompasses various elements that are essential for the operation and functionality of a building. This includes electrical systems that power lighting, outlets, and appliances, as well as telecommunications systems that enable communication and data transfer, and security systems that enhance the safety and surveillance of the building.

By focusing on these systems, option C highlights the critical aspects that relate to electrical infrastructure in building design. Electrical systems are central to a building’s power supply and operational efficiency, while telecommunications connect the building to external networks, and security systems protect the premises.

In contrast, the incorrect options pertain to different categories entirely. For example, water supply and waste removal relate to plumbing, HVAC encompasses heating and cooling systems, and acoustical and fire suppression systems deal with noise control and fire safety, respectively. Each of these options addresses distinct areas of building design that do not fit under the electrical category.
