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

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

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

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

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

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
