Intelligent Buildings Management System (IBMS)

Terminology

Building Management Systems (BMS) also knownas Building Automation Systems (BAS), BuildingManagement and Control System (BMCS), DirectDigital Controls (DDC) and Building Controls (BC)

Other terms associated with Control Systemsinclude:

• Supervisory, Control and Data Acquisition(SCADA)

• Programmable Logic Controllers (PLC)

• Energy Management System (EMS)

• Data Gathering Panels (DGP)

System Architecture

IBMS links the functionality of individual pieces of buildingequipment so that they operate as one complete integrated system.




Dubai - 2016


Architecture of IBMS

• BMS Hardware

• Field Devices

• Networks

• Displays




Dubai - 2016


What does an IBMS do?

Day to day building operation

The most common primary function of the BMS isthe control of the building HVAC system including;

• Chilled Water Plant

• Cooling Towers

• Tenant Condenser Water

• Heating Water Plant

• Exhaust Systems




Dubai - 2016



Building Control Applications

• Zone temperature monitoring and control

• Zone Variable Air Volume (VAV)

• CO2 monitoring and control (Air Quality)

• Air handling unit

• Air flow/pressure control

• Toilet, car park, kitchen and general exhaust fancontrol

• After Hours Building Control




Dubai - 2016



Measuring and Monitoring building performance

• Data

• Graphical User Interface (GUI)

• Dashboards

• Graphs

• Alarms

• Reports




Dubai - 2016



Interaction with other building systems

• Lighting system

• Emergency lighting system

• Fire protection system

• Security system

• CCTV system

• Meter system

• Etc.




Dubai - 2016


Benefits of IBMS

• Real-time monitoring

• Documentation

• Customized control strategies

• Flexibility and ease of changes

• Integration of all building systems

• Automated recovery of failure

• Running/operational cost reductions

• Reduce labor cost

• Tenants’ comfort

• Indoor quality

• Safety and security

IBs Protocols

Concept

• Building systems (HVAC, security/access, lightingcontrol, building safety, and physical plantcontrol) talk to one another using a commonlanguage (protocol)




Dubai - 2016

• ASHRAE

• BACnet

• DALI

• Dynet

• Energy Star,

• EnOcean

• KNX

• LonTalk

• Midac

• OPC

• OpenTherm

• OpenWebNet

• S-Bus

• ZigBee

Issues Related to Intelligent Buildings

IB technologies are expensive …1• Intelligent building technology investments

typically pay for themselves.

• Return of investment within one or two years

• Delivering energy savings and other operationalefficiencies.

• Some building management programs havegenerated a positive return on investment withinseveral months.




Dubai - 2016


IBs are about energy and cost2• Energy

• Cost

• Efficiency

• Comfort and satisfaction

• Productivity

• Safety and security

• Integration

• Accuracy

• Flexibility

• Etc.




Dubai - 2016


Intelligent buildings are for certain building type ..3• Office buildings

• Residential buildings (Intelligent House Index)

• Educational buildings

• Hospitals

• Banks

• Sports centers

• Etc.

It is about features and benefits of intelligencerather than building typology.




Dubai - 2016


Intelligence are for new buildings…4• Existing building have the opportunity to

experience architectural intelligence.

• Building management and IT systems tooptimize system performance and simplifyfacility operations.

• Wireless technology made it easier fortraditional buildings to transform into intelligentones.

• Examples of transforming buildings are many.

• 311 South Wacker, Chicago, is an example.

Intelligence are for new buildings…4

311 South Wacker, Chicago, USA

• Designed by Kohn Peterson & Fox

• Built in 1990

• 65 Story Tower (293 m tall)

• 1.4 million ft2

• It was once the tallest reinforcedconcrete building in the world.

• Upgraded Building Automation System (BAS) in2000




Dubai - 2016




• South Wacker installed a state-of-the-art energysaving system and LED lighting

• South Wacker is the first major office tower inChicago to install wireless Pneumaticthermostats connected to a cloud-basedintelligent building system.

• A total of 944 thermostats were installed.




Dubai - 2016




• The system utilizes real time data to makeoperational energy saving decisions.

• Many environmental improvements.

• The property saved about 2.1 million kWh peryear which is the equivalent of planting 37,130new trees.

• The building earned this substantial award forthe West Loop office tower.




Dubai - 2016


Intelligent buildings are not attractive to tenants..5

• IBs are argued to:• improve energy efficiency,

• reduce cost, and

• improve productivity

• Therefore, they are valuable to tenants.

• Numerous studies and surveys showed IBs to bemore attractive compared with traditionalbuildings.

“We shape our buildings, and afterwards our buildings shape us”

Intelligent buildings are not attractive to tenants..5




Dubai - 2016


Intelligent buildings are complicated to operate..6• Self-know, self-decide and self-respond.

• Intelligent building management system is ofteneasier to operate and maintain than a buildingthat lacks automated systems.

• Integration.

• Communication (e.g. dashboards, alarms, etc.)

• Problem self diagnosis.

• Minimum human intervention




Dubai - 2016


Intelligent buildings might promote losing jobs..7• Minimum human intervention

• Less employment for operation

• 5 to 7.1 million jobs will be lost due to automation(in the richest countries) in the next 5 years.

• 4 out of 10 Canadians might lose their jobs due totechnologies in the next 10-20 years.

• Employment shift
