Your Guide to Choosing the Best Building Automation System

Building automation is fast becoming standard in Nigerian homes as people look to increase the comfort and productivity of their properties and save energy costs.

With many building automation solutions available, getting a system that meets your specific needs is essential.

This article provides a detailed guide on how you can choose the best building automation system for your property.

What is a Building Automation System?

A building automation system (BAS), also known as a building management system (BMS) is a system that enables the automated control and monitoring of various building systems and operations. It integrates and controls multiple building systems, including heating, ventilation, and air conditioning (HVAC), lighting, electrical, plumbing, fire safety, security and more.

The BAS connects and coordinates various systems in a building through a central control interface. This enables the owners or facility managers to efficiently manage and optimize building performance, reduce energy consumption and costs, improve operational efficiency and enhance occupant comfort and productivity.

Automation systems are commonly used in commercial, industrial, and institutional buildings. However, in recent times, BAS has been used in residential and smaller buildings. Therefore, whether you’re looking to automate specific systems in your home or business premises, BAS is an excellent solution for you.

What are the Key Components of a Building Automation System?

Building automation systems are made up of these key components:


Sensors are devices that measure various environmental parameters or building occupancy. They track the temperature, humidity, lighting levels, air quality, and even the occupancy of a building.

After gathering data on the environmental and occupancy state of a building, the sensor transmits them to the controllers for necessary actions.


Controllers are the central hub of the building automation system. They receive data from sensors, process them and send commands to the actuators to regulate the building systems based on predefined algorithms and inputs.

For example, if the data returned by the sensor indicates that the building is hot, the controllers send out commands to the HVAC systems to lower the building’s temperature.

Output Devices

Output devices like relays, actuators, control valves, etc., are integral to the building automation system. They’re responsible for executing commands and controlling various building systems based on inputs received from sensors and commands issued by the BAS controller or user.

There are stand-alone and networked output devices. Stand-alone output devices have their internal power supply and communicate directly with the BAS controller. Networked devices use a central power supply and communicate with the BAS controllers through a communication network.

User Interface

The building automation system isn’t complete without a terminal or user interface. It’s the graphical user interface (GUI) or web-based dashboard that allows you to monitor building system performance, adjust settings, and receive alerts and notifications in real-time.

Most user interfaces are detailed to the point of showing every piece of equipment on the building and displaying them with photo-realistic graphics. This enables you to figure out fast where to send a command.

Networking Infrastructure

The networking infrastructure is the thread that holds the entire system together. The BAS relies on a communication network, including wired and wireless communication protocols such as BACnet, Modbus, LonWorks, and Ethernet, to connect and exchange data between other components.

The Benefits of a Building Automation System

BAS has many benefits you’d find helpful, both in your residential and commercial properties. Here are some of them:

Energy Efficiency

Building operating systems optimize energy usage by monitoring and controlling systems such as HVAC, lighting and other equipment. It commands these systems based on occupancy schedules, environmental conditions and energy demand. For example, when no occupants are in a room, the BAS system maximizes energy by turning off lights and other energy-consuming equipment.

Cost Savings

The cost of energy consumption, especially in most places in Nigeria, is outrageous. BAS enables you to lower utility bills and operational expenses by reducing equipment runtime during unoccupied periods.

Furthermore, due to the data analytical tools in most BAS units, you can predict when systems need maintenance and follow it up proactively. This enables you to reduce equipment downtime and repair costs.

Improved Comfort and Productivity

Comfort and productivity are perhaps the most notable benefits of a building management system. These systems ensure comfortable and productive indoor environments for occupants by maintaining optimal temperature, humidity, and air quality levels.

With these environmental conditions at their optimal best, you’d find it easier to function in an enclosure.

Remote Monitoring and Control

Modern BAS has remote monitoring and control capabilities, allowing you to access system data, adjust settings, and troubleshoot issues from anywhere with an internet connection.

The remote accessibility of BAS reduces response times to alarms and faults and minimizes the need for on-site visitations, saving you time and resources.

Enhanced Building Security

BAS integrates seamlessly with building security systems like access control, surveillance cameras, and intrusion detection to enhance the security of your property. It provides you with centralized control and monitoring of your security devices, improving the situational awareness of your building.

With BAS, you can effortlessly streamline your security operations and maintain a safe environment for your occupants and assets.

How to Choose the Best Building Automation System

Choosing the best building automation system involves considering various factors to ensure they meet the specific needs of your building. Here’s a guide:

Define Your Building Automation Objectives

You must start with determining what you want to achieve with a building automation system. It might be to manage energy in your building efficiently, improve occupant comfort and productivity or predict when your smart home equipment needs maintenance.

Defining your objectives will help you choose a building automation system that suits your needs and saves costs.

Assess Building Requirements

Evaluate the various aspects of your building to see opportunities for automation and optimization. Start by evaluating the size and layout of the building, taking note of the number of floors, rooms, and zones.

Also, analyze the usage patterns of the building, including occupancy schedules and peak demand periods. Understanding how the building is used throughout the day and week will help you determine the optimal control strategies for HVAC, lighting and other systems.

Check for Compatibility and Scalability

The BAS compatibility with your existing smart home systems is essential. You must buy a system that is compatible with your HVAC systems, lighting, security, and other smart building equipment.

It’s also essential to make provisions for future upgrades. Consider a BAS that you can easily scale to accommodate future building expansions or equipment upgrades.

Examine the Key Features

Look for systems with modern features like real-time and remote monitoring, automated scheduling, and usage analytics. Also, ensure your chosen system can integrate with other building systems and technologies, such as lighting, HVAC, fire safety and security systems.

Check Support Services

High-quality support is essential for getting the best out of your building automation or management systems. Research and choose a reputable supplier with a proven track record of reliability and quality support services.
