Abstract:Under the influence of machine aesthetics and honesty creed, flat surfaces formed the mainstream ideal image of ceilings in early modern architecture, and their significance, forms and methods of implementation have constantly changed with the development of the times. The end of the ceiling equipment system has evolved from being initially located below the ceiling surface, to being flush in the early days of suspended ceilings, and then to being behind in contemporary times. While the suspended ceiling surface has become independent in contemporary times, it has also gained aesthetic significance beyond practicality. The environmental management technology integrated in the suspended ceiling space provides the possibility of responding to the external environment. The change in technical expression from explicit to implicit, allows environmental factors to have an impact on architecture that goes beyond mere form.
