As the core spatial carrier for human habitation, work, and activities, buildings' "characteristics" determine the form, performance, and adaptability of the space, while "installations" are key system components that ensure the building's proper operation and enhance the user experience. The two complement each other: architectural characteristics provide the integration foundation for installations, while installations enhance the practicality and comfort of architectural characteristics through their functions. Together, they form a complete architectural system from "form design" to "functional implementation," applicable to a wide range of scenarios, including residential, commercial, and public buildings.
