Energy is considered to be one of the major elements of development, and can act as an indicator to assess the rate of growth and economic development. International forecasts show that global energy demand is increasing with a consistent momentum and in the next 20 years, global energy consumption will rise by more than %50. Therefore, the emerging theory of intelligent buildings and the necessity to control energy consumption in large buildings can be traced back to several years ago. This theory has led to many researches concerning design and development of this type of building with the goal of reaching the maximum energy efficiency for smart infrastructures.

First level: By the local controllers (hardware) the management of each area is assigned to one of the local controllers.

Second level: central software controls the entire local fire alarm systems, cameras and access control systems.

Building Automation System (BAS) department was established in Kerman Tablo in 2006.BAS has accomplished essential and immense experiences in design, consultancies and after sale services due to the implementation of different projects, in providing cooperation of the highest level in terms of consultancy to governmental and privately owned organizations.

Building Management system works on two levels:

Due to the breakdown of management control levels, done by the software system of the central and local control, the local controller can continue its activities even if the communication between local control and central software is disconnected, and can maintain the control of the related area. Therefore, there will be no gap in the building management.  Meanwhile, the communication interruption will be reported graphically by the central control software.

BAS system consists of:

- Closed Crcuit Television (CCTV)

-Access Control

-Fire Alarm

-Broadband over Power Line (BPL)

the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-bus. Besides, vendors are also producing BMSs that integrate using Internet protocols and open standards such as Device Net, SOAP, XML, BACnet, Lon Works and Modbus.  Such systems can be seen and utilized in: Chillers, Industrial Coolers, Boiler, Fan- Coil (Radiator) & Heater, Air Conditioner, Pump, Water Heater and Lighting.
