2. Best Practices Include
Integration of control systems
Overlooked control strategies (convenience)
Advanced control strategies (energy)
Easy access to information

3. Reasons for Using BAS (Building Automation Systems)
Improved control of equipment
Minimize operational cost
Provide users with information

4. Smart Control of Equipment
Integration allows all equipment to work together
Operate your systems as “a system”
Maximize control while minimizing costs
Smarter control can reduce labor costs
as well as reducing energy costs

9. Best Practices Control Strategies Often Overlooked
Integrate control air system pressure
Automatic ventilation for chiller outages
Freeze protection for cooling coils
Global commands for holidays & set points
Chiller plant demand cycling

10. Best Practices HVAC Design and Control
Standard heating and cooling set points
Variable air volume (VAV) distribution
Occupancy sensors for lighting & HVAC
Space centered disch. temp. control
Integration of all 4 of the above strategies
Cascading demand systems

11. Cascading Demand Control
Run only that
equipment
needed to
satisfy the
demands of
the space
Occupancy
control at
the space
level, not
the AHU
level

12. Access to Information WMU has wireless Internet access to:
Graphics screens
Scheduling
Alarming
Trending
Documents & drawings
Anything on the world-wide web

13. WMU BAS Statistics 64 buildings with DDC Over 2,300 control devices
At least six different manufacturers
Over 22,000 control points
BACnet, LonWorks, & 6 proprietary protocols
10 environmental controls people
