A Beginner’s Guide To Building Management Systems

As buildings and their internal systems become more complex, the need for efficient, centralized control has never been greater. This is where a Building Management System (BMS) comes in. This article aims to provide a comprehensive introduction to Building Management Systems, delving into their purpose, benefits, and the intricacies of their operation.

What is a Building Management System (BMS)?

At its core, a Building Management System (BMS) is an intelligent, centralized system designed to monitor and control a building's mechanical and electrical systems. It's a computer-based control system that manages and controls the building's environment, including heating, ventilation, air conditioning (HVAC), lighting, power systems, and security. These systems are also often referred to as Building Automation Systems (BAS).

The central control functionality of a BMS allows for ease of operation and improved efficiency, as all systems can be monitored and adjusted from a single interface. This not only simplifies building operations but also allows for optimization of energy usage, resulting in cost savings over time.

Who Uses Building Management Systems?

Building Management Systems are used across a wide range of facilities, including but not limited to commercial buildings, office spaces, schools, hospitals, data centers, and hotels. The key stakeholders who interact with a BMS are typically building owners, facility managers, and maintenance staff, all of whom can utilize the system to ensure the building's optimal operation.

If you're a building owner or facility manager, the potential benefits of a BMS are significant. The ability to have real-time control and information about your building's systems allows for proactive management, reducing downtime and maintenance costs.

The Benefits of a Building Management System

Energy Efficiency: A BMS can optimize energy use, reducing waste and lowering energy costs. It does this by adjusting systems based on occupancy, weather, and time of day, among other factors.
Cost Savings: By optimizing energy usage and allowing for predictive maintenance (identifying issues before they cause system failure), a BMS can lead to significant cost savings over the lifespan of a building.
Comfort and Productivity: A well-managed building environment contributes to the comfort and well-being of its occupants, which can boost productivity in workspaces and satisfaction in residential and hospitality environments.
System Integration: A BMS brings all building systems under one umbrella, making management and monitoring more efficient and less time-consuming.
Sustainability: By minimizing energy waste, a BMS contributes to the sustainability goals of a building or organization, reducing its carbon footprint.
Occupant Health: Particularly relevant in densely populated areas like New York City, a BMS can significantly enhance the indoor air quality of a building. By continuously monitoring and controlling HVAC systems, a BMS can maintain optimal temperature and humidity levels, reduce pollutants, and ensure adequate ventilation. This leads to a healthier indoor environment, reducing the risk of health issues such as allergies, respiratory conditions, and the spread of airborne diseases.
Occupant Safety: A BMS can also be programmed to respond to high levels of carbon dioxide, which can cause headaches, dizziness, shortness of breath, and impaired cognition if allowed to accumulate. With a BMS in place, you're not only improving the comfort of occupants, but also actively contributing to their overall safety, health and well-being.

The Role of Building Management System Integrators

Building Management System integrators play a crucial role in the implementation of a BMS. They are the experts who design and install the system, ensuring that all the various building systems work together seamlessly.

Integrators, like T.M. Bier & Associates, work closely with partners such as Distech Controls & Schneider Electric to deliver a tailored BMS solution that meets the specific needs of your building. This process involves in-depth knowledge of various building systems and a deep understanding of how to optimize these systems for efficiency and comfort.

Building Management System Retrofits & Upgrades

For buildings with outdated control systems, a BMS retrofit or upgrade can be a game-changer. Older buildings often have separate, unconnected systems for HVAC, lighting, and other functions. A BMS retrofit involves integrating these disparate systems into a centralized BMS, resulting in improved efficiency and ease of operation.

Building Management System Installs

When installing a new BMS, the focus is on designing a system that will meet the building's unique needs. This involves selecting the right hardware and software, designing the system's architecture, and commissioning it to ensure it functions as expected.

The process of installing a Building Management System involves several steps, which can be briefly outlined as follows 1 :

Preparation & General Requirements: This includes ensuring all civil works are completed for the area, obtaining clearance from authorities, referring to approved shop drawings and ensuring required materials are available. Any discrepancies, damage etc., found will be notified and reported for further action.
BMS Installation Procedure: This involves several stages including conduiting and cabling, installing VAV and FCU controllers, control valves and actuators, and DDC panels and field devices.
Central Peripherals and Integration: Here, bus loop wiring is carried out from the Central Controller to all the VAV’s & DDC as per the approved schematic drawings. The peripherals with controllers hubs are installed in the BMS control room.
Installation of Field Devices: Finally, field devices for HVAC equipment are installed as per approved shop drawings and manufacturers recommendations.

This is an overview of the installation process, and the specifics can vary based on the unique needs of your building and the specific BMS solution being implemented.
