What is BMS (Building Management System) ?

A Building Management System (BMS), also known as a Building Automation System (BAS), this is a computer-based control system integrated in buildings to monitor and control the building’s mechanical and electrical equipment. These systems helps in optimize the building’s operational efficiency and improve the comfort and safety of its occupants.

Key Components and Functions:

1. HVAC Control: Manages heating, ventilation, and air conditioning systems to maintain and manage the optimal indoor climatic situation and energy efficiency.
2. Lighting Control: Automates lighting systems to ensure proper illumination through the surface, often based on occupancy sensors or scheduled times which we have introduce.
3. Energy Management: With the implementation of automation in the building it Monitors and controls energy usage to reduce costs and enhance sustainability.
4. Security Systems: This is important to Integrates with surveillance cameras all over, access control, and alarm systems to enhance building security.
5. Fire and Safety Systems: Oversees fire alarms, smoke detectors, and emergency systems to ensure building safety and make the rigid system to ensure the safety.
6. Maintenance Management: Tracks and schedules maintenance tasks, ensuring that systems are kept in good working order specially for the Fire and security system.

Benefits of a BMS(Building Management System):

Energy Efficiency: Reduces energy consumption by optimizing system performance and identifying areas for improvement.

Cost Savings: Lowers operational costs through efficient management of resources and preventive maintenance.

Enhanced Comfort: Maintains consistent indoor conditions, improving occupant comfort.

Improved Safety: Ensures systems are functioning correctly and can quickly respond to emergencies.

Data Collection: Provides valuable data for analysis, helping to make informed decisions about building operations.

These are comprises of three unit : –

1 ) Controlling Operations

2 ) Operator Room

3 ) Management Operations

Controlling Operations

In HVAC systems, controlling operations are managed by units like Fan Coil Units (FCU), Air Handling Units (AHU), chillers, Variable Frequency Drives (VFD), pumps, and boilers, each serving specific functions and connected to controllers for energy management. The Building Management System (BMS) regulates operations, such as adjusting fan speeds and chiller activity based on load demand, with multiple chillers activating during high demand and only one during low demand. Pumps and boilers similarly adjust to heating and cooling requirements, ensuring efficient operation through coordinated signals from the BMS.

Operator Room

The operator room, also known as the main control room or BMS room, is the central component of the BMS system. It monitors and controls all operations. Temperature adjustments for specific rooms, activation and deactivation of equipment like the AHU , scheduling of functions, and setting alarms for any occurrences are all managed from the BMS. The room allows us to modify values such as cooling levels based on our needs. Additionally, it regulates the opening and closing of dampers as per the BMS deployment. In essence, this room serves as the essential hub of the building management system.

Management Operations

Apart from controlling operations, management operations are also important. Our BMS system corrects and monitors the status of electrical appliances. We can control functions such as elevators, monitor energy meters, water meters, flow of water, and CCTV cameras in the BMS. All these systems are connected in the building management system, allowing us to control and monitor operations, change data, and easily debug and solve problems. This system also helps in energy management and conservation.

Plan Your Building Management

The best time to choose the right BMS is when planning a new building or renovating and refurbishing an existing building. Optimizing the placement and configuration of sensors and network infrastructure is important for good data collection. Work correctly and provide timely and effective information. If an existing building is a candidate for a BMS (perhaps an older building is being renovated), there are a few things to check before installation. Ask the following questions:

Assess the building’s electrical and communications systems for compatibility with new technology, ensuring air conditioning functions properly and air quality is safe. Consider replacing windows with power-insulated glass, and evaluate the safety and security of interior and exterior doors. Verify that lighting meets local regulations and staff needs, and check if fire alarms are compliant. Ensure water and sewer lines are safe, power supply installations are appropriate for continuous use, and communication systems are effectively configured. Lastly, confirm the elevator’s safety, ensuring all standards align with original building regulations before management installation.

Integrated Building Management Systems (iBMS)

Integrated Building Management Systems (iBMS) have recently emerged as a more comprehensive version of Building Management Systems (BMS). While BMS centralizes building systems, iBMS goes further by integrating the entire building environment, including access control, video surveillance, and fire prevention systems. By consolidating all systems, both BMS and iBMS streamline building management and serve as a single control point for the entire building. As a result, most new buildings are now equipped with a building automation control system, and starting in 2025, it will be mandatory throughout the European Union.
