Automated tasks and building management systems.

Automated tasks and building management systems.

Imagine a facility manager starting their day at 6 AM, manually adjusting heating systems across 50 floors, checking hundreds of lighting circuits, and responding to countless maintenance alerts. 

In a non-automated building, this professional must physically inspect each system, make individual adjustments, and rely on occupant complaints to identify issues. Time is consumed by routine tasks, leaving little room for strategic facility improvements or emergency responses. 

Now, picture the same building equipped with an automated Building Management System (BMS). 

The facility manager arrives to find the heating already optimized based on weather forecasts, lighting adjusted to occupancy patterns, and potential equipment failures flagged before they occur. Through automated task execution, what once required hours of manual intervention now happens seamlessly in the background. 

The shift from manual to automated task management helps reduce operational costs, improves occupant comfort, and increases staff productivity.

In this article, we will go over the benefits and examples of automated tasks for building management systems from A to Z.

What is a Building Management System (BMS)?

A Building Management System (BMS), also known as a Building Control System (BCS), is a centralized platform that monitors, manages, and coordinates a building’s mechanical and electrical equipment. Every BMS integrates vital building functions, including HVAC, lighting, security, fire systems, and power management.

How does a BMS work?

The BMS operates through a network of controllers, sensors, and equipment interfaces. Operators monitor system dashboards, process alerts, and manage various subsystems through a central interface. BEMS workflow
