Building Automation ControlNetwork
Local Operating Network
Prominent Open Protocols in the Building Automation Market
Versus
Both protocols allow for dissimilar manufacturers of products to interoperate over a common network by data sharing, alarm and event management, trending, scheduling and remote device network management.
Versus
Both protocols allow for the following applications:HVAC ControlFire detection and alarmSecurityLighting controlSmart Elevator ControlUtility company interface…and more
Versus
Benefits of both Protocols:•Single operator workstation for all systems•Competitive system expansion•Possibility of integrating all building control functions•Interoperability
Vs.
Who’s behind each protocol?
Echelon-The developer and distributor of LonWorks a for profit corporation.
ASHRAE- A non profit organization that advance the arts and sciences of heating, ventilation, air conditioning, refrigeration and related human factors to serve the evolving needs of the public and ASHRAE members.
Purpose:
The Standard is to define data communications services and protocols for the computer equipment used for monitoring and control of HVAC&R and other building systems and to define, in addition, an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.
• Why LonWorks?– End device oriented systems– Smaller networks– Simple systems– Expansion plans are minimal
• Why BACnet?– Larger networks-application
driven– Controller oriented– Need to move large amounts of
information– Complex systems– Future expansion
Benefits of BACnet
• No charge for its use—anyone may develop implementation without cost.
• Maintained by an ASHRAE committee representing all sectors of the industry.
• Designed specifically for building control.
• Can be implemented in devices of any size.
• Can be readily enhanced and improved.• Not tied to present technologies.
Why Should BACnet Succeed?
• User Demand• No fixed architecture• Object model is easily extended• Doesn’t depend on current
technology• Broad participation in its
development• Many vendors are committed to it• Global interest

Specifying BACnet - The Simplified Process
Determine why BACnet is a requirement (one OWS, multi-vendor product interfacing or data sharing, future expansion, etc.). The reasons will in turn determine how detailed the specifications need to be.
1.
Lay out a proposed architecture and determine at what levels in the system BACnet is desired.
2.
For each network level in the system determine the media that will be used. If it is specified up-front, then each vendor is responsible for routing to this media if routers become necessary.
3.
Specifying BACnet - The Simplified Process
Select BACnet interoperability functions for each device using BIBBS:

4.
Determine who is responsible for system integration.
