OPTIMIZING THE ADMINISTRATION OF ELECTRICAL
ENERGY BY USING BUILDING MANAGEMENT SYSTEMS
In order to efficiently manage the electrical energy consumption of the
buildings it is needed an intelligent system named Building Management
System (BMS), which can be structured on 4 levels: peripherals, input/output
modules, local stations, central management station. The local stations manage
the peripheral in their area and can communicate with other stations and with
the central one. The main modules of a BMS are: HVAC station, Chiller station,
Lighting (internal and external), Security, Elevators. The central management
station has a mainframe with add-on cards for communication with the local
stations and the peripherals. The software permits monitoring the power
distribution at all levels, and also changing the parameters for various system
components (pumps, ventilators, heating, chillers etc). All events must be
recorded in database and presented to the user when needed. Modern BMS
can also be controlled remotely (via Internet). Using a BMS for electrical energy
management can significantly decrease the energy consumption of a building.
