Delta Controls & BACnet®

BACnet® Overview

BACnet affords facility owners and managers maximum flexibility and cost-effectiveness by allowing control products made by different manufacturers to be integrated into a single, uniform system. BACnet is designed to allow HVAC/R, lighting, life safety, access, security, power, vertical transportation and other building system control devices to interoperate.

Why BACnet®?

BACnet is the only protocol recognized as an international standard.

BACnet International

BACnet allows intelligent systems from various industries and manufacturers to exchange information, such as temperatures, setpoints, schedules, trend logs and alarms, and coordinate equipment operation to achieve optimum building performance. It saves facility owners/managers the costs of purchasing, engineering and maintaining custom interfaces for supervising packaged HVAC equipment (e.g. chillers), as well as integrating diverse building systems such as HVAC, lighting, fire, elevators, electrical services, etc.

BACnet empowers facility owners/managers with the flexibility of expanding and adding systems without being locked into one manufacturer. Instead, they can select the most appealing technology and services available and gain investment protection because current systems can be expanded without replacing the entire system.

The BACnet standard is independent of specific hardware platforms and supports multiple LAN technologies, including the Internet. This allows BACnet to evolve unencumbered as new technologies develop according to public demand, unlike open protocols where the underlying hardware and LAN technologies are controlled by one or few commercial enterprises.

As an ANSI/ASHRAE standard controlled by an ASHRAE standards body, BACnet cannot be changed without public review. Users have a say in any changes that may affect the protocol. Conversely, proprietary or public (open) protocols can be changed at the discretion of the creator without the customer being made aware.

BACnet International

BACnet International is a non-profit organization comprising manufacturers of BACnet products from various industries as well as individuals involved in systems design and implementation.
