What is the Internet of Things (IoT)? The IoT is a system of devices with the ability to send, receive, and exchange data via an internet connection. These devices are then able to operate with little human intervention based on the data received from the internet or other devices on the cloud network. In general, for commercial buildings, the current approach to the design of building automation systems (BASs) is to treat the building as a vacuum, unaffected by the surrounding climate, environment, societal patterns, and historical HVAC system data. The IoT not only allows access to this data, it grants the opportunity to navigate the mechanical, electrical, plumbing, and fire (MEPF) controls according to this data and even act predictively.
