BACnet is an unconnected, peer network where any device can send service requests to any other device. These objects are defined by the BACnet specification and have both required and optional data. For example, the Control and Information Protocol (CIP) used in industrial application, BACnet uses objects to represent data on a network. Today, the majority of users prefer to use Ethernet. This leads to cost savings over proprietary systems, but also tremendous savings in resources, installation costs, maintenance costs, and energy savings. To further simplify things, with BACnet, devices from various manufacturers work in conjunction with each other with little or no additional integration. In these applications, motion detectors can be used to more efficiently measure human presence and activity and with a timer to make sure lights are off after hours. In a typical HVAC application BACnet would handle lighting, heating/cooling with a programmable thermostat, smoke detection and some form of security/safety applications. As a result, the BACnet protocol uses mobile and cloud-hosted devices, head-end computers, general-purpose direct digital controllers, and application-specific or unitary controllers with equal effect. Secondly, BACnet provides the ability to control and monitor any building automation process, to meet the needs of users, integrators, and equipment vendors. As a result, this approach standardizes the representation of processes and data. Its benefits include reusability, refactoring, extensibility, maintenance and efficiency). The BACnet protocol uses an Object-oriented approach (Object-oriented programming allows for simplified programming. Therefore, BACnet became an alternative to the proprietary and closed protocols offered by large vendors that were in existence at that time. Furthermore, in June of 1995, ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers) also adopted this same standard. In June of 1987, a group of HVAC and Building Automation professionals met in Nashville to develop this standard, open protocol specifically for the building automation industry. For example, by sharing sensors and data, BACnet gives our applications similar abilities to sight, hearing, taste, smell and touch to help us make better decisions. The protocol displays how data is represented and moved between BACnet nodes on the network and the services used to move it.
