• Other terms associated with Control Systems include:
– Supervisory, Control and Data Acquisition (SCADA)
– Programmable Logic Controllers (PLC)
– Energy Management System (EMS)
– Data gathering panels (DGP)
– Modbus, Lonworks, and Bacnet – All refer to communications protocols
– ‘Front End’ – legacy term used to refer to the BMS Operator Workstation
• Most Common Current industry term –
– Building Management System (BMS) or
– Building Management and Control Systems (BMCS)

• BMS systems are “Intelligent” microprocessor based controller networks
installed to monitor and control a buildings technical systems and services
such as air conditioning, ventilation, lighting and hydraulics.
• More specifically they link the functionality of individual pieces of building
equipment so that they operate as one complete integrated system.
• Now installed in every major building or facility with the availability of
direct integration into all other building services such as security, access
control, CCTV, fire, Lifts and other life and safety systems.
• Current generation BMS systems are now based on open communications
protocols and are WEB enabled allowing integration of systems from
multiple system vendors and access from anywhere in the world.

User defined menus.

• Alarm notifications of faults reduce downtime
• Automated change over of failed equipment

Optimal start and stop of plant
• Building warm up and cool down cycles
• Night purge
• Automatic Seasonal plant sequence selection
• Seasonal temperature setting adjustments
• Load based control strategies
• Economy cycle control including CO2
• Equipment runtime monitoring and duty cycling
• Occupancy control and control setback

• EMS is a dedicated software packed for the monitoring and management of electrical,
water, gas and thermal energy metering systems

 Tuning and optimisation
 Importance of System Documentation
 System Maintenance, what, how often and by whom
 Life cycle expectations and considerations

BMS Tuning and Optimisation are not
the same thing….
• BMS Tuning or control loop tuning
ensures that the equipment operates
in a stable, predictable and repeatable
• Optimisation focuses on operating the
equipment in the most energy efficient
manner without impacting on the
controlled variable
• The first stage of optimisation includes
BMS loop tuning.

Functional Description (FD)
– Details the configuration of the BMS
– Overview of the building services
– Describes in detail each of the BMS control strategies and sequences of
– Documents interaction between each part of the system
• Point Schedules
– Detail all connected devices and their point type
– Critical for planning and system engineering
• Control System Drawings
– Should include a network architecture drawing
– Detail the physical wiring connections to controllers
– Useful for fault finding and establishing spare capacity

The BMS belongs to the building owner who should act as its
administrator managing BMS access rights
• The BMS should be maintained with an appropriate level of servicing
• As with any software driven system, data and files should be backed up on
a regular basis
• Critical components should be identified and checked at regular intervals
• BMS functions such as trend data, reports and alarms can be used to
perform maintenance by exception
• Maintenance should be approached as the performance of the controlled
system not individual components, i.e. AHU or Chiller Plant
• While the BMS equipment vendor should be utilised to maintain the
critical components, other suitably qualified technicians can be utilised for
field equipment
