Integrated Building Management System (IBMS) is a complete information delivery system that monitors and controls a variety of systems and functions at an optimal level of efficiency.

Integrated Building Management System functions with the co-ordination of three major interface namely the Building Automation, a centralized Server and Security System which includes Surveillance and Access Control System, management of the visitors

Integrated Building Management System is a programmed arrangement installed in buildings to manage and monitor different functions of the premise such as

BAS (Building automation): Building Automation System (BAS) is a micro processor control system designed to monitor and control all parameters of HVAC, electrical, PHE, fire protection, elevators and other building services/utilities. BAS helps in conserving energy by executing various energy efficient programs for optimized performance of the systems and to assist the operation and maintenance of the installation

The system is DDC (Direct Digital Control) based with functions distributed both physically and functionally over the field controllers. The DDC interface, with sensors, actuators and environmental control systems, carries out various functions of energy management, alarmdetection, time / event / holiday / temporary scheduling, communication maintenance & report generation.

  • Closed Circuit Surveillance (CCTV)
  • Access Control System
  • Fire alarm: Addressable System
  • Public Address System (PA)
  • Light control system
  • Fire Hydrant - Automatic Sprinkler System
  • Gas Suppression System
  • Public Address System (PA)
  • Very Early Smoke Detection Apparatus (VESDA)

Benefits of IBM
  • Integrated building systems in a single, streamlined, multi-service network infrastructure
  • Standardized man-machine interface decreases risk of mistakes
  • Centralized control, monitoring, maintenance, management
  • Consolidated existing or diverse systems into one powerfully integrated platform
  • User-friendly and easily accessible online monitoring
  • Decreased energy, resources and labor costs
  • Efficient data recording, reporting and analysis
  • Real-time information for prompt and enhanced decision making
  • Improved customer satisfaction
  • Optimized efficiency
  • A more environmentally-friendly



The system shall be implemented as an integrated, open solution, which enables Service Center Connectivity through standard Building Operating System (BOS) interface.

The System Architecture shall consist of four levels:

  • - Service Level
  • - Management Level
  • - Control Level
  • - Field Level

The system shall be completely modular in structure and freely expandable at any stage. Each level of the system shall operate independently of the next level up as specified in the system architecture. For Example, Control Level shall operate independently without support from Management Level. The system shall be fully consistent with the latest industry standards. To enable efficient functional System integration and to provide maximum flexibility and to respond to changes in the building use, the system offered shall support the use of Lon Works (Local Operating Network (LON), Modbus; Ethernet TCP/IP and Internet Communication technologies.


BACnet is a communications protocol for building automation and control networks. It is an ASHRAE, ANSI, and ISO standard protocol.
BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control, lighting control, access control, and fire detection systems and their associated equipment. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of the particular building service they perform. Proper communication between building automation devices is critical for maximizing building energy efficiency.

The BACnet specification defines all aspects of the BACnet protocol. This document focuses on the following:

  • Objects – A BACnet object is a logical representation used in the BACnet protocol. It can be used to represent many different aspects of a control system. Examples are:
    • A physical device (device objects)
    • A temperature input (analog input)
    • A relay control (binary output)

  • Services – Information exchange between objects is provided by services. Services are used to perform reads, writes, and I/O. The object that provides the service is a server and the object that requests the service is the client. Most objects can be both a server and a client, depending on the system's needs.

  • Properties – A property contains information about an object. Objects may contain a large collection of properties, some of which may be required for the specific object type. Every object in BACnet must have at least the following three properties:
    • object_identifier
    • object_name
    • object_type

BACnet objects:

BACnet is an object-oriented protocol. I/O points, schedules, and devices are examples of objects. An object may be a single point or a group of points that perform a specific function.

Each object has a set of properties, such as the object's name, type, and present value, which describe its behavior or govern its operation. Every property has a name and a value. The following are properties that might exist in a BACnet analog input object:
