Building Management System

A Building Management System (BMS) is a computer-based control system installed in buildings. It controls and monitors the building’s mechanical and electrical equipment, such as ventilation, lighting, power systems, fire systems and security systems.

A very basic BMS consists of software, a server with a database and smart sensors connected to an internet-capable network. Smart sensors around the building gather data and send it to the BMS, where it is stored in a database. If a sensor reports data that falls outside pre-defined conditions, the BMS will trigger an alarm

Good practice

uilding 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 component to managing energy demand.

Czech Republic

Construction on The Orchard, a high-performance office and hotel centre, began in 2007. Developed by The Red Group, The Orchard creates a dynamic environment for both work and leisure time in the heart of Ostrava, Czech Republic. The ecologically friendly building design incorporates Schneider Electrics state-of-the-art Building Management System. The Orchard has one of the most sustainable designs in the country and incorporates a state-of-the-art building management system.

Potential interchange performance improvement

  • energy savings – it is estimated that a BMS can save a business between 5% and 30% on utility costs
  • effective monitoring and targeting of energy consumption
  • increase productivity
  • simplified control of electrical and mechanical equipment


Resources can vary greatly depending on the size and type of project. Several potential factors include:

  • whether the system will be retrofitted to an existing facility or installed in new construction
  • whether the system will involve control at the individual zone level or simple control of the major pieces of equipment
  • need to use specialised sensors for a certain application

Since no two buildings are alike and the needs of each facility are different, there is no standard estimate for a typical system.
