Light efficiency : If the ceiling reflects and diffuses light properly, there is less need for artificial lighting, resulting in improved energy efficiency and a better working environment.
Acoustic comfort : The acoustics for the ceilings should be good which should enhance the sound that is required, while eliminating or reducing unwanted sound.
Accessibility and service management : A suspended ceiling should allow for concealing the plumbing, the air-conditioning system and electrical wiring. A good ceiling system also enables ease of access to such ducts and wires.
Other functional parameters : Apart from these parameters, fire safety, moisture resistance, ease in cleaning, load-bearing capacity, installation and environment friendliness are important.
