The Basics of a Building Management System
The Basics of a Building Management System
July 13, 2017

A building is not just a structure built of steel and concrete. There are several systems in operation that keep the people and devices in it running smoothly. A building management system is needed to control and monitor the proper coordination and operation of these systems.

Types of Systems Within Any Building

The separate systems within a building include the following:

  1. Mechanical System. These include the HVAC or the heating, ventilation and air conditioning systems in the building.
  2. Electrical System. Electrical dashboards, lighting, generators, uninterrupted power supply system.
  3. Utility System. Elevators/escalators, Fire Alarms, Security Monitoring, Communications.
  4. Waste Disposal System. Sanitary as well as garbage disposal systems.

Elements of a Good Building Management System

Now, managing these systems individually is both a pain as well as an inefficient use of resources. In order to improve the efficiency of management, the following is needed to control and coordinate these systems together.

  1. Protocols. The building management system needs at least two basic protocols, which are as follows:
    1. Bacnet. This involves a data communications system named for Building Automation Networks. With this protocol, all automation systems are linked together.
    2. LonWorks. This is the control system which integrates into the data communications system to govern all existing building systems. Each system identified above is centralized using a common network.
  2. Architecture. This aspect of building management systems has two levels:
    1. Level 1. This part of the building management system is the connectivity of all controllers linked together through a router or a gateway.
    2. Level 2. This part of building management systems involves itself with the connectivity of the router or gateway to the central control and monitoring system.
  3. Devices. This aspect of building management systems is broken down as follows:
    1. BMS Controllers and Software. This is the integration of individual devices to the central router to provide data as well as provide orders to the operation of the different systems.
    2. Field Devices. These are specific electronic or mechanical devices attached to the individual building systems.
    3. Cables and Conduits. These are the relays used to connect via daisy chain to the different building systems to manage them.

These are some of the key elements of any quality building management system. However, individual systems may vary in terms of the protocols used as well as devices supported. 

Helpful read as someone who is unfamiliar with the subject!

My building management is strong like my axe.
