In the context of commissioning, what does "system integration" refer to?

System integration in the context of commissioning specifically pertains to the coordination and collaborative functioning of various building systems—such as HVAC, lighting, security, and energy management—so they operate seamlessly together. This holistic approach ensures that the interconnected systems enhance the overall performance, efficiency, and effectiveness of the building. Poor integration can lead to inefficiencies, increased energy consumption, and a negative impact on occupant comfort.

The focus of system integration is on creating a cohesive environment where different systems communicate and interact correctly, optimizing the control strategies and functionality of each component. This coordination is crucial for achieving the intended operational goals of a building and maximizing its performance.

In contrast, options like isolating systems or creating them to operate independently diverge from the goal of integrating systems since they prioritize autonomy over collaboration. Developing new systems without regard to existing components also misses the essence of system integration, which relies on leveraging current technologies and systems for improved functionality.
