BMS Explained

What exactly is a Building Management System (BMS)?

  • The question we get asked the most is “what exactly is a building management system and what does it do?” A building management system (BMS) in layman’s terms could be described as a computer-based control system that is installed in a building to control and monitor the building’s mechanical and electrical equipment such as heating and ventilation. Many people don’t even realise their building has a BMS but this if often a sign of a system operating effectively. A BMS works behind the scenes to ensure that a building is automatically controlled to provide the required level of heating or cooling at different times of the day as required.

    In recent years there has been a switch in emphasis towards energy conservation, many building management systems are now referred to as BEMS (building energy management system). A BMS is the most effective method to monitor and control energy use within a building. It can control which areas of a building are heated or cooled, what times of the day / days of the week and what temperatures are required.

    A BMS typically consists of one of more control panels installed within a plant room which are wired to various sensors, valves and switches etc within the building. This allows the BMS to monitor and control the building effectively.

    Temperatures are monitored by installing sensors, these vary in type, typically an outside air sensor would be installed to monitor the outside temperature, various room sensors would be installed to monitor and control different zones and immersion / duct sensors would be installed on heating pipes / air handling units to monitor and control the heating / cooling.

    Heating valves or duct louvers have actuators mounted to them which allow them to be controlled by automatically opening and closing them.

    Meters can also be monitored to provide information on energy usage including gas, electric and water, sub meters are often installed to determine energy use in specific areas of a building.

    Within the BMS control panel there are controllers which hold the strategy that is used to control the building. Nyke Energy Services Ltd are accredited systems integrators of Trend Controls, Cylon Controls and EasyIO Controls. All manufacture a range of controllers used in building management systems.
