What is A Building Management System — BMS System
BMS is a microprocessor & computer based control system which is rtow installed in most of the buildings in order to control and monitor the installed equipment including all mechanical and electrical equipment and systems like HVAC, lighting, power, water supply and filtration system and also integrated with other systems like life and safety systems such as fire alarm, fire fighting and fire suppression systems.As a typical example BMS system consists of both software and hardware components. There are many bms software programs available which are configured in a hierarchical manner typically. There are some proprietary software or protocols such as C-bus and Profibus etc. fvlajority of Vendors are also producing Ofyasystem software that are having ability of integration with internet protocols and open standards like DeviceNet, SOAP XML, BACnet, LonWorks and Modbus etc.
Building .Management Systems are most commonly implemented in large projects with extensive mechanical, electrical, and plumbing systems. Systems linked to a BMS typically represent 40% of a building's energy usage; if lighting is included, this number approaches 70%. BMS systems are a critical component to managing energy demand.
In addition to controlling the building's internal environment, BMS systems are sometimes linked to access control (turnstiles and access doors controlling who is allowed access and egress to the building) or other security systems such as closed-circuit television (CCTV) and motion detectors. Fire alarm systems and elevators are also sometimes linked to a BMS, for monitoring. In case a fire is detected then only the fire alarm panel could shut off dampers in the ventilation system to stop smoke spreading and send all the elevators to the ground floor and park them to prevent people from using them in the event of a fire.
Building systems integrated with BMS include:
• lighting control
• Electric power control
• Heating, Ventilation and Air-conditioning (HVAC)
• Security and observation
• Access control
• Fire alarm system
• Lifts, elevators etc.
• Plumbing
• Trace Heating
• Closed-circuit television (CCTV)
• Other engineering systems
For Building tenant/occupants some of the benefits include:
• Good control of internal comfort conditions
• Possibility of individual room control
• Increased staff productivity
• Effective monitoring and targeting of energy consumption
• Improved plant reliability and life
• Effective response to HVAC-related complaints
• Save time and money during the maintenance
IIMS for Maintenance Companies
• Ease of information availability problem
• Computerized maintenance scheduling
• Effective use of maintenance staff
• Early detection of problems
HMS System For Building owner
• Individual tenant billing for services facilities manager
• Central or remote control and monitoring of building
