Examples of engineered systems in commercial buildings include:
Heating, ventilation and air conditioning (HVAC): These systems provide heating, cooling and ventilation to maintain a comfortable indoor environment. They may include boilers, chillers, air handlers and ductwork.
Electrical: These systems provide power to the building and may include generators, transformers, switchgear and distribution panels.
Plumbing: These systems provide hot and cold water, drainage and waste management to the building. They may include water heaters, pumps and pipes.
Lighting: These systems provide light to the building and may include fixtures, controls and dimming systems.
Fire protection: These systems are designed to detect, notify and suppress fires in the building. They may include fire alarms, sprinkler systems and fire extinguishers.
Security: These systems provide protection to the building and its occupants from intrusion and may include CCTV, access control and intrusion detection.
Communication: These systems provide voice and data communication to the building and may include telephone systems, data networks and audio-visual systems.
Building automation systems: These systems control and monitor the various building systems, including HVAC, lighting, security and fire protection, to optimize energy efficiency and comfort.
Elevator and escalator systems: These systems provide vertical transportation in the building.
