What is a Building Management System?

A Building Management System (BMS), sometimes called a Building Automation System (BAS), is a computer-based system installed to control and monitor a building's electrical equipment such as ventilation, lighting, energy, fire systems, and security systems. It consists of software and hardware.

A BMS is crucial to managing demand for energy in a cost-effective way and essential to all new builds. It allows owners and landlords of buildings to reduce energy costs and provide optimum comfort for users, tenants and residents of the buildings. It allows remote management of heating, ventilation and air conditioning (HVAC) so that maintenance staff do not have to spend time visiting each building or room to shut down, switch on or adjust temperature levels or air conditioning.

Because data is consolidated in a single system, a BMS improves reporting and information management leading to quality, informed decision-making, better performance and a reduction in energy use, thereby saving money.
