2 With me today Cassandra Beck Pacific Northwest Area Service Sales Manager - 14 years with Siemens Mike Anderson Service Sales Engineer for the South Puget Sound 4 years with Siemens

3 Objectives Building Automation System Basics Quick introduction to Building Automation Systems Service best practices Interoperability and Integration Energy monitoring and management

4 BAS Basics Background Dictionary Definition Verb: To exercise authority or restraint over; regulate; adjust to a requirement Noun: A set of instruments used to regulate or guide a system or machine (not just on / off ) Common Definition Control is a system of components that read input variables, process a set of instructions and send outputs to achieve a desired outcome

5 BAS Basics Common Terms BAS Building Automation System BACS Building Automation and Control System BMS Building Management System EMS Energy Management System EMCS Energy Management Control System DDC Direct Digital Control

6 What can BAS control? Temperature Pressure Lighting Building Security Modes of Operation Humidity Air Flow Fire and Life Safety Energy Efficiency Daily or Seasonal

12 BAS Considerations System and vendor capabilities Backwards and forwards compatibility Access to training and troubleshooting tools Interoperability and integration capabilities Expandability Migration plans and lifecycle management Open or proprietary protocol Maintenance and support services Remote access and remote alarm notification Other in-house capabilities References

13 Most vendors strive to develop a service partnership through service agreements with their customers. Common services include: Software Updates Inspection and maintenance of software and hardware System health assessments Lifecycle management Energy management and continuous commissioning Customer training Remote services Service and Maintenance

14 Service and Maintenance Benefits of a good service partnership Saves money! Maintained systems last longer Reduced risk of system failures and downtime Improved occupant comfort Improved energy efficiency

16 Integration and Interoperability Protocol Set of rules to follow agreed upon format to send and receive messages between computing devices Standard Protocol Developed with public input and cooperation open to anyone without components owned by an enterprise governed by an independent body, certified by standards bodies (i.e. ANSI, ISO) FOX PROTOCOL

17 Integration and Interoperability What is PICS? Protocol Implementation Conformance Statement BACnet spec sheet with a list of the device's BACnet capabilities Required for every BACnet device Contains: General product description Details of product's BACnet capabilities Which LAN options are available Several other items relating to character sets and special functionality * PICS is the place to start to determine device capabilities *

Integration and Interoperability Process: A BACnet manufacturer submits to BTL for compliance testing a BACnet device along with its PICS If the device meets the minimum requirements for

18 Integration and Interoperability Process: A BACnet manufacturer submits to BTL for compliance testing a BACnet device along with its PICS If the device meets the minimum requirements for BTL certification and correctly implements all BIBBs, object types, data link layer and network options listed in its PICS, the BTL mark is awarded
