BMS: what it is and how to add IoT sensors to an existing system

In recent years, building management has evolved rapidly. Regulatory pressure, ESG goals, and the increasing need to reduce operating costs have pushed companies and public institutions to invest in smart systems, environmental sensors, and IoT solutions.

The problem? In many cases, these devices collect valuable data… that ends up going unused.

It’s common for data generated by sensors—measuring air quality, occupancy, temperature, humidity, or energy consumption—to remain trapped in siloed platforms, disconnected from the building’s main automation system: the BMS (Building Management System). This creates a paradox: buildings become “technological,” but not truly smart.

What’s missing is dialogue, connection. And without integration, even the most accurate data loses its operational power.

In this context, the opportunity is clear: leverage existing IoT data to enhance the BMS and drive the control logic of technical systems, making buildings truly responsive, sustainable, and efficient.

Integration: A Real-World Challenge

One of the most common issues we see on the ground is precisely this: integration between new IoT devices and existing systems is anything but straightforward. In many buildings, collected data remains “isolated” or “locked” in non-interoperable platforms, drastically limiting its operational value and preventing intelligent, centralized control.

At Aircare, we’ve tackled this issue head-on. Our approach is built around interoperability and technical simplicity.

We implement a flexible integration strategy based on open protocols and industry standards that can communicate with all major PLCs and BMS systems on the market. Each project is supported by custom data register configurations, tailored to the systems being controlled and the automation logic already in place.

In short: we eliminate the integration issue before it even arises, thanks to a technology that’s natively compatible with our clients’ real infrastructure.

A Plug-and-Play, Natively Interoperable Solution

Aircare enables full integration of data from its devices—such as energy meters, IAQ and comfort sensors, and occupancy sensors—into the client’s BMS infrastructure, with no need for structural changes or new hardware.

We use the same LoRaWAN gateway already deployed for device connectivity, which makes data available through a simple Ethernet connection. This data is immediately accessible to the BMS via a standard like Modbus TCP, fully customizable based on the client’s preferred parameters and system control logic.

Turning Data into Actionable Intelligence

This integration transforms environmental and behavioral data into real operational inputs for the BMS, making automation systems smarter and more responsive.

The tangible benefits include:

Automatic HVAC regulation based on actual occupancy and real air quality levels
Energy load optimization through fine control of consumption and environmental conditions
Prompt response to anomalies, with alert and automation logic managed directly by the BMS

An Evolutionary Step to Maximize Existing Investments

Organizations that have already equipped their buildings with a BMS can evolve their systems with Aircare, without replacing existing infrastructure—boosting the intelligence and responsiveness of what’s already in place.

The Aircare–BMS integration acts as a powerful accelerator toward goals like:

Energy efficiency, with measurable and trackable savings
Healthier indoor environments, improving comfort and productivity
Environmental certifications and ESG ratings, thanks to high-quality, integrable data
Flexibility and scalability, to meet new operational or regulatory needs

Integrating IoT data into your BMS isn’t just a smart move—it’s the key to transforming a tech-enabled building into a truly smart one.
