Knowing When It’s Time To Upgrade Your BAS

Not sure if your building automation system needs updating? Here are a few reasons our customers choose building automation upgrades.

Improved equipment performance

When your BAS is sluggish or not as responsive as it used to be, it’s time to consider an upgrade. An upgrade not only improves equipment performance, but it also optimizes energy efficiency.

Advanced front-end software

If your BAS doesn’t use modern front-end software, you’re missing out on reporting capabilities and business intelligence. Not to mention, modern systems offer access to BAS controls via a convenient, web-based portal.

Break ties with proprietary systems

Many customers choose to upgrade their BAS to free themselves from a legacy system. A proprietary BAS relies on a single manufacturer for servicing, repairs, and part replacements. Switching to an open system allows you to integrate any brand of equipment, for the ultimate freedom of choice.

Building Automation Upgrade vs. Replacement

Choosing whether to upgrade or replace a BAS is a difficult decision. Here are some important considerations when comparing an upgrade versus a replacement.


If your BAS technology is currently supported, there are likely a range of upgrade options. However, if your BAS is obsolete—that is, unsupported by the manufacturer—it’s time to consider a replacement.

System performance

Upgrading—along with proper servicing—significantly improves the performance and energy efficiency of BAS-controlled equipment. But there comes the point where updates and maintenance no longer help, and a replacement is the only way forward.


Ultimately, it may come down to comparing the cost of an upgrade against the cost of a replacement. Upgrading typically costs far less; however, if a system is already near the end of its useful life, a cost assessment could reveal you’re better off replacing it.
