What Are The Differences Between A BMS vs BAS?


The Building Management System (BMS) and the Building Automation Systems (BAS) are two different systems that can both be used to control building functions. A BMS is more focused on monitoring and maintaining a building’s operations, while BAS is designed for energy efficiency. Let’s take a closer look at some of the differences between these two systems.


Building Automation Systems (BAS) is a subset of Building Management Systems that encompasses automation and controls for HVAC, lighting systems, as well as other building-related functions. Vendors have been attempting to distinguish BAS from BMS because it includes more sophisticated analytics and improved automated control; however, owners see this distinction with an emphasis on the automating aspects such that they consider BAS to be just another form of BMS.


Building Management Systems

A Building Management System (BMS) is a computer-based system that controls and monitors mechanical and electrical plants such as HVAC, lighting, power systems, fire systems. It also includes security cameras to monitor activity outside of buildings for potential threats. All this information can be monitored from anywhere in the world with internet access!


  • Save time by remotely monitoring and controlling your system
  • Spend less time fixing issues that arise from poor building management
  • Stay in the loop without ever leaving your home or office
  • Be notified when different events occur


Building management systems is an important tool that building managers need in order to monitor and ensure the efficiency of energy usage. It helps them provide a working environment with optimal comfort while keeping expenses at a minimum for both landlords and renters by avoiding excessive utility costs. When implemented correctly, effective use of these programs can lengthen equipment lifespan as well as decrease running hours which leads to lower maintenance costs overall. The end result? A more efficient system all around like the following:


  • Decreases running hours – lower maintenance costs
  • Extends equipment lifespan
  • Provides a more comfortable environment with energy efficiency in mind


Building Automation Systems

When it comes to building administration, a BAS is an excellent option for those looking for something more basic. It doesn’t offer as many features or analytics and automation controls as other smart devices such as BMSs do but still has the ability to reduce energy costs among its benefits.


Features of BAS

  • This Intelligent System Could Be Used In Any Building To Manage Occupancy And Automatically Adjust Settings Based On Sensor Variations.

It might even make it easier for the occupants by eliminating manual adjustments that are often needed when there is a change of personnel or some other specific event that changes the use pattern. This smart technology will help buildings operate more efficiently while also improving work-life balance for those stuck inside!


  • Automate The Most Time-consuming Maintenance And Operations Tasks.

The most time-consuming maintenance and operations tasks should be automated so they can happen without any human intervention.


  • Use Of Remote Controls.

Imagine being able to lock down the entire building with a single button press, reduce ventilation settings without touching the HVAC or turn on all lights simply by flipping one switch.
