Sensors: The Eyes and Ears

A network of sensors are strategically placed throughout the building, constantly gathering information about the environment. These sensors act as the "eyes and ears" of the BMS, monitoring everything from temperature and humidity to occupancy and light levels. This data provides the foundation for intelligent automation and control.  

Controllers: The Brain

The controllers are the "brains" of the operation, processing the information gathered by the sensors and making decisions based on pre-programmed parameters or user input. They act as the central command, sending signals to various building systems to adjust settings and optimise performance.  

User Interface: Your Control Panel

The user interface is your window into the BMS.

Whether it's a computer screen, a mobile app, or a dedicated control panel, the user interface provides a visual representation of the building's systems and allows you to monitor and set the parameters for the controllers. So if your goals are to save energy, manage your energy demand or simply make life easier for your facility managers, the control panel will do just that.

How a Building Management System Works

1. Sensing the Environment

As we know from the previous section, sensors are what allows the control system to know what needs to happen. With technological advancements in sensor technology, building operators now have access to a range of data points including: 

• Temperature: Keeping tabs on the indoor climate for optimal comfort.  

• Humidity: Measuring moisture levels to maintain a healthy environment.  

• Occupancy: Detecting the presence of people to adjust lighting and ventilation accordingly.  

• Light Levels: Assessing natural daylight to optimize artificial lighting.  

• Air Quality: Monitoring CO2 levels and other pollutants to ensure fresh air circulation.  

• Security Breaches: Detecting unauthorized access or intrusions.  

• Fire and Smoke: Triggering alarms and safety measures in emergencies.  

2. Processing the Information

The data collected by the sensors is transmitted to a central controller, the "brain" of the BMS. This controller acts like a powerful computer, processing the information and making decisions based on pre-programmed parameters or user input.  

3. Taking Action

Based on the processed data, the controller sends commands to various building systems, such as:

• HVAC: Adjusting heating, ventilation, and air conditioning to maintain optimal temperature and air quality.  

• Lighting: Turning lights on or off based on occupancy or daylight levels.  

• Security: Activating alarms, locking doors, or controlling access points.  

• Fire Safety: Triggering the sprinkler system, alarms, and evacuation systems.  

4. User Interface: Your Command Center

The BMS provides a user interface, typically a computer screen or mobile app, allowing building managers to monitor and control the system. This interface provides a visual representation of building performance, allowing for adjustments, troubleshooting, and data analysis.  

In essence, a BMS acts as a central nervous system for your building, constantly monitoring, processing, and responding to changes in the environment to ensure optimal performance, comfort, and safety.

Components of a Building Management System

Now that we know what a Building Management System is, (a.k.a building automation systems), how they work and what they monitor, we can take a deep look into how the management system works on each of the electrical systems.

This is another way smart buildings can find substantial energy savings. Lighting control and automation allows a a building to intelligently adjust its lighting based on occupancy and the amount of natural daylight. Automated lighting control not only enhances convenience but also plays a crucial role in energy management and making your company energy efficient. By reducing unnecessary lighting usage, you contribute to a greener building and lower operating costs.

Security and Access Control Integration

A BMS System can seamlessly integrate with your building's security systems, providing a centralised platform for surveillance, and intrusion detection. This enhanced level of security not only protects your assets but also provides peace of mind for building occupants and facility managers, making it a cost effective solution to security.

Fire Detection and Alarm Systems

In the event of an emergency, every second counts. A BMS can be linked to your fire detection and alarm systems, enabling rapid response and minimising potential damage. This integration ensures that critical alerts are communicated swiftly, alerting other building to facilitate prompt evacuation and ensuring the safety of everyone in the building.

Energy Monitoring and Energy Management

Gain valuable insights into your building's energy consumption patterns with a BMS. By tracking energy usage across various systems, you can identify areas for improvement and implement data-driven strategies for energy savings. They can also track and monitor renewable energy sources that your building may have, centralising energy use data into a single system. Having this in place can also allow proper distribution of energy when required. This translates to a cost effective and sustainable building operation.

Fault Detection and Diagnostics

A proactive approach to maintenance is essential for minimising downtime and costly repairs. A BMS excels at fault detection and diagnostics, continuously monitoring building and electrical systems for potential issues. The Building Management System can identify when system upgrades are needed, reducing time for facility managers. By identifying problems early on, you can address them promptly, ensuring smooth building operation and extending the lifespan of your equipment.

Benefits of Implementing a BMS

Investing in a Building Management System (BMS) for modern buildings is more than just a smart move – it's a strategic decision that pays off in numerous ways. We've already seen how this computer based system can save time, save money and optimise a building's mechanical assets. But if the pro's of these management systems has gone amiss, here's how a BMS can benefit your building:

Building Management System FAQs

What is a Building Management System?

A Building Management System (BMS) is a sophisticated computer-based system that acts as the central control hub for a building's essential functions. It monitors and manages building systems, including HVAC (heating, ventilation, and air conditioning), lighting, security, fire safety, and energy consumption. Think of it as the brain of your building, ensuring optimal comfort, efficiency, and safety for occupants.  

What is BMS and how does it work?

A BMS works by collecting data from sensors placed throughout the building. These sensors monitor parameters like temperature, humidity, occupancy, and light levels. This data is then processed by a central controller, which makes decisions based on pre-programmed settings or user input. The controller then sends commands to actuators, which are devices that physically control things like valves, dampers, and switches, adjusting building systems accordingly.  

What does BMS stand for in buildings?

BMS stands for Building Management System. It's sometimes also referred to as a Building Automation System (BAS).  

What is the difference between BMS and IBMS?

While the terms BMS and IBMS are often used interchangeably, there is a subtle distinction.  

• Building Management Systems (BMS): Traditionally focuses on monitoring and controlling the building's core mechanical and electrical systems, such as HVAC, lighting, and security.  

• IBMS (Integrated Building Management System): Takes integration a step further by incorporating a wider range of systems, including fire safety, access control, energy management, and even business applications. IBMS aims to create a truly intelligent building that can adapt to changing needs and optimize performance across all functions.  

Essentially, IBMS can be seen as a more advanced and comprehensive evolution of BMS, with a greater emphasis on integration and intelligent automation.
