Automation and process streamlining is a consequence of technological advancements. A smart building is the term for a high-tech building. The most common elements of building systems whose control can now be fully automated or facilitated e.g. by operating an app installed on a smartphone, are alarm and monitoring systems; HVAC; blinds/shutters; lights; and audio/video equipment. The application of smart systems can bring financial benefits by saving on electricity costs, provide comfort to the users/occupants, and significantly increase the safety of a residential or office space.
