Scalable Smart Building BEMS, from Silicon to Solution, with Advantech Module and NXP i.MX 95 Platform

Industry Trends

Smart buildings that can "think" are coming. 

In the past, BEMS was just a "meter reading system." It only checked power meters, recorded usage, and made monthly reports to remind people to save energy. 

Now, everything is different. Electricity prices keep rising. Companies must reduce carbon emissions. ESG has become a key business KPI. Governments also require energy disclosure and compliance, so BEMS can no longer be just a monitoring tool. It must become a smart system that can think and make decisions. 

BEMS is evolving — from "just seeing data" to "making real-time energy decisions."

What's New in Modern BEMS

The new BEMS does more than check power usage. It also manages: 

• Air conditioning (HVAC) 
• Lighting
• Energy storage
• EV chargers

Challenge

The vision is great, but reality is tough: 

1. Lighting, energy storage, and EV charging need real-time response. If system performance is not enough, the system may crash. 
2. Projects run for 10+ years. Security and long-term supply must be reliable. 
3. Some projects are one building, some are a whole community. The system must scale up and down. 
4. Every project is built from scratch. NRE is high, time-to-market is slow, and success is hard to copy.

Solution

NXP i.MX 95 + Advantech SMARC (AOM-5521) + OSM (AOM-2521) 

This creates a scalable and reusable energy management platform. The building now has a "big brain" and each device has a "small brain": 

• SMARC (AOM-5521) = the building's brain
• OSM (AOM-2521) = the brain inside each device

How It Works

It is the central controller of the energy system. It decides how to use energy in the most efficient way. 

• Manages HVAC, power distribution, and energy optimization
• Balances loads 24/7 to avoid peak demand
• Connects devices via Ethernet and CAN
• Runs Linux-based energy management and analytics 

OSM (AOM-2521) – The Device Brain

Built into meters, controllers, energy storage, and EV chargers. 

• Controls each device in real time at the edge
• Processes data locally and sends key data securely to the building brain or cloud
• Low power, stable for long-term operation

In the end, every device becomes smarter, and the whole building works together as one system.

Why Advantech chooses NXP i.MX 95

NXP i.MX 95 solves real customer pain points:

• One SoC can run real-time control and system applications
• Built-in security by design, not added later
• Industrial-grade design for 10+ years of operation
• Fewer external components = simpler and more stable system

When the platform is stable, projects can last longer.

Results

Advantech and NXP move from project-based development to platform-based growth:

• Faster development
• One software platform runs on both SMARC (AOM-5521) and OSM (AOM-2521)
• Lower system cost, no need to redesign for every project
• Better energy efficiency, real-time decisions at the edge
• Easy scaling: from one room → one building → whole community

One SoC. One software platform.

From central control to edge devices are all covered.

Conclusion

BEMS is no longer just about saving energy. It is the core system of energy transformation from passive monitoring to real-time decisions and long-term evolution. Advantech + NXP i.MX 95 is the key engine that makes this evolution real.
