5 reasons to upgrade your building automation system
Last updated: August 2026Highlights
- Aging hardware and software expose your facility to cybersecurity threats, increase maintenance costs, reduce energy efficiency and limit your team's ability to keep occupants comfortable
- Data in your Building Automation System (BAS) can be used to support proactive maintenance, extending asset life and reducing costly business disruptions
- Integrating fire and life safety systems into your BAS gives you a digital window into your entire building, further increasing potential savings
Why you can't afford to keep an outdated BAS
It's been nearly 35 years since the launch of the Metasys building automation system. With the phaseout of aging components and more pressure than ever to measurably improve building performance, you can't afford an out-of-date BAS.
Here are five reasons to start now on your Metasys upgrade path.
1. Reduce cybersecurity risk
Software and hardware upgrades can help you prevent unauthorized access, meet IT standards and stop depending on security patches. The latest Metasys release uses zero trust technology, encrypted communication and cybersecurity best practices like password and account management. Your IT department benefits from centrally managed user permissions and credentials without multiple software packages, and end users benefit from fewer passwords.
Key features include:
- The award-winning Cyber Health Dashboard, highlighting potential security concerns
- Multiple secure methods for connectivity, including IEEE 802.1x support and BACnet/SC
- FIPS 140-2 Level 1 certification/compliance for network engines and server software
- Advanced user permissions to streamline system administration
2. Maximize uptime for connected assets
Breakdowns disrupt operations and upset occupants. Empower your team to spot potential issues early and resolve them faster, increasing resilience and keeping occupants safe and comfortable. Get the data to support proactive maintenance, improving building performance, extending asset life and reducing costly business disruptions.
- Automated information gathering and remote diagnostics make service calls more efficient
- Options such as Fault Detection and Fault Triage guide even inexperienced staff to find and fix issues fast
- Device health indicator monitors 28 predefined and up to 15 customer-defined communications and performance attributes to optimize Metasys SNx engine performance
- The newly flattened architecture supports up to 800 IP devices, giving you increased flexibility
- Turnkey servers can greatly reduce IT coordination time – up to four hours
Optimize building performance with Metasys
3. Do more with less time, less money and less staff
The world-class Metasys user interface just got easier. With streamlined navigation and fewer clicks to critical information, your team will spend less time navigating and more time taking action. Intuitive navigation by building space, with photo-realistic graphics, cuts the learning curve and delivers key information in fewer clicks. Features like System Activity and the alarm status banner speed prioritization, troubleshooting and response.
4. Improve energy management and decarbonization
Deliver comfortable, energy-efficient spaces with less effort and cost. Powerful tools such as energy dashboards with three-click configuration simplify operations and reporting. Built-in ASHRAE Guideline 36 sequences for both airside and waterside applications help cut energy use an average 30%. Metasys meets many regulatory requirements, potentially enabling you to qualify for incentives and satisfy stakeholders.
5. Unify building systems for a bigger ROI
Aging and outdated building systems can be frustrating to operate – and cost your organization time and money. Upgrading your Metasys BAS integrates new technologies and unifies building systems from commissioning to retrofit. And the ability to integrate fire and life safety systems gives you a digital window into your entire building, further increasing potential savings.
