How are plumbing, electrical, heating ventilation and air conditioning (HVAC), and transport systems generally categorized?

Plumbing, electrical, heating ventilation and air conditioning (HVAC), and transport systems are classified as building systems because they are essential components that support the functionality, safety, and comfort of a building. These systems are integral to the overall operation of a facility and are designed to work together to ensure proper environmental conditions, such as temperature control, air quality, and water supply.

Building systems encompass a wide range of infrastructure and equipment that are vital for daily operations. This categorization emphasizes their role in the design, maintenance, and functionality of buildings. Understanding these systems as part of the broader building architecture allows facilities managers and operators to effectively address issues that arise, plan for maintenance, and ensure compliance with relevant codes and regulations.
