How Airi BMS works
Airi BMS is Pre-Trained, Pre-Engineered, Edge-AI Powered and Scalable System
Measured Indoor Climate Data
Airi’s wireless mesh network, easily repositionable sensors, and Airi communication protocol ensure reliable indoor climate data transmission.
Airi Audit
Provides a 30-day assessment of indoor climate and gives AI-driven improvement suggestions.
Quick and Discreet Setup
Airi BMS becomes operational with the swift and almost unnoticeable actions of Airi technicians while the building is in active daily use.
Integration
Integration with any existing or new HVAC system is rapid with Airi BMS, securing desired indoor climate quality.
Airi BMS self-learning control algorithms
Guarantee adaptive response of HVAC for securing the desired indoor climate quality.
Airi BMS client benefits and uniqueness
Energy class upgrade
From class E to B recorded in the National Building Register using Airi BMS. Improved energy class made more favorable financing terms available to the building owner.
Zero-CAPEX for Airi BMS
Standard solution enables property owners to avoid investment of hundreds of thousands of euros that would otherwise be unavoidable.
Edge Intelligence – unique to Airi BMS
The vast majority of data and decisions made by AI to secure the desired indoor climate are processed at the Edge computing layer by “Edge-AI”. This has enabled a “Pre-Engineered” Airi BMS: a self-learning and self-optimizing system with feedback loops, requiring no additional engineering work for subsequent buildings.
The system
Unique components to make it perfect
Sensors
Wireless room-level sensors read temperature, CO₂, humidity and occupancy continuously every 60 seconds, giving an accurate picture of conditions throughout the building. Battery-powered, rechargeable over USB-C.
Mist Mesh
Our proprietary wireless mist-mesh network connects sensors and HVAC controllers across the building via Airi communication protocol without new control wiring.
Prediction engine
The model learns the building’s thermal behaviour and its real occupancy, predicts the weather and energy prices to adjust HVAC continuously. Self-learning, rather than a fixed rule set that someone has to maintain.
Edge AI
Data can be processed and decisions made at the Edge, inside the building — not in the cloud. Self-learning and self-optimizing, with feedback loops: control continues on site even if the connection to the cloud drops.
Built for every asset class
One platform. Every building type.
Offices
Multi-tenant floors with uneven occupancy. Control follows how the building is actually used, not a fixed schedule.
Food retail
Long trading hours and a heavy ventilation load. Air quality standards maintained while the equipment stops running flat out around the clock.
Shopping centres
All HVAC equipment managed by one system, with comfort held through full trading hours and visibility tenant by tenant.
Hotels
Guest-facing comfort standards, with occupancy that changes night by night. Rooms are heated and cooled according to real use rather than around the clock.

The capital these owners did not spend
Each building faced a conventional automation or HVAC project to reach basic energy saving targets. No investment was made by the customer.

Wired automation build for the same scope — hotel

Capital from the owners
Approximately €1.7 million of capital expenditure avoided across these three buildings. Across larger portfolios, the avoided-capital potential can reach millions.
In every case the Airi BMS service fee is lower than the achieved savings and is structured never to exceed it.
“Instead of investing €1 million in building automation and HVAC upgrades, Airi BMS offered a service model that delivers better results than conventional building automation, with an annual fee that never exceeds the savings generated.” Coop Estonia, member of the management board

Regulation
What regulation already requires
German EnEfG energy audits
Energy-audit obligations are widening under the EED and EnEfG framework, and companies newly brought into scope faced their first audit deadline on this date. An audit identifies the savings. It does not fund them, and it does not oblige anyone to act on them.
EPBD automation threshold
The building automation threshold for non-residential buildings falls to 70 kW, subject to the directive’s conditions and to national implementation. Buildings in that band will need compliant automation — and most of them never justified a project.
EPBD worst-performing stock
Member states must bring the worst 16% of non-residential buildings below a national threshold by 2030, and the worst 26% by 2033.
Partners
New revenue stream – from the buildings you already service
Every service portfolio contains buildings where an automation project was never going to be funded. Airi BMS turns that opportunity into recurring revenue — no technology investment on your side, no conflict with your installed base.
Recurring revenue alongside project revenue.
A monthly service fee from measured savings, in buildings that generate neither a project nor a maintenance contract today.
An offer for owners who said no to capital investment.
Zero CAPEX reopens the conversations that are closed — nothing to put through an investment committee.
Know which buildings are worth upgrading.
The 30-day measured Audit result tells you which buildings in a portfolio justify a full project, so you stop bidding blind on the ones that never will.
No new control wiring.
A trained technician can install the hardware rapidly without turning the deployment into a conventional controls project — this makes a hundred small buildings economic instead of theoretical.

Technology and delivery partners
About
Twenty years of wireless research, targeted at buildings
The mesh protocol and Edge AI capabilities underneath Airi BMS came out of two decades of research at Tallinn University of Technology, Defendec, Microsoft Research and SUNY Buffalo. The technology was initially commercialized at Defendec, where more than 60,000 devices have been deployed across 60 countries. Airi BMS applies these technology components, algorithms and know-how to existing commercial buildings, and the hardware is designed and manufactured in Europe.
