The intelligent operating system for buildings

The building finally gets its own operating system.

Unitmax OS connects the physical building, live data, equipment, people and operational processes in one intelligent system.

From a digital building model to real-time insights, energy intelligence and automation.

01The problem

We’ve digitized everything around buildings. But not the building itself.

Buildings already use software for payments, CRM, maintenance, documents, communication, accounting and analytics.

But these systems often operate independently.

The result is fragmented data, duplicated work and no complete understanding of what is happening inside the building.

  • 01

    Fragmented systems

    Many tools. No single operational context.

  • 02

    Siloed data

    Information is scattered across different systems.

  • 03

    Manual work

    The same information is entered and processed repeatedly.

  • 04

    Limited visibility

    No complete real-time picture of the building.

  • 05

    Slow decisions

    Finding the right information takes time.

  • 06

    Higher operating costs

    Problems are discovered late and opportunities for optimization are missed.

A building should not be a collection of disconnected systems.

02The digital layer of the real building

Unitmax OS starts with the building itself.

At the core of Unitmax OS is not CRM.

Not billing.

Not another dashboard.

At the core is the building.

Unitmax OS creates a structured digital model of the property and connects its spaces, systems, equipment, sensors, people, documents, operations and history.

All of that becomes one continuously evolving digital context.

03The core asset

Separate data becomes knowledge about the building.

A traditional system may know:

Sensor 213 reported value 1.

Unitmax OS understands the context:

This sensor belongs to the heating system of this building, serves these apartments, is connected to this equipment, is maintained by this contractor and has this technical history.

  • Building
  • Systems
  • Equipment
  • Sensors
  • Events
  • Operations
  • History
  • Contractors
  • Documents
  • Finance
  • People
  • Units
  • Spaces
  • Floors

The longer a building operates in Unitmax OS, the richer its digital context becomes.

04Platform architecture

Not a set of modules. One architecture for the building.

05From signal to resolution

Unitmax OS doesn’t just know what is in the building. It understands what is happening in it.

06Energy intelligence

Understand how the building uses resources.

Energy information is often scattered across utilities, meters, building systems and spreadsheets.

Unitmax OS creates one unified energy layer.

08People + building

A building is more than equipment.

Buildings are physical assets, but they are operated by people.

Unitmax OS connects the building with residents, property managers, contractors and daily operational processes.

  • Residents
  • Charges & billing
  • Payments
  • Communication
  • Documents
  • Contractors
  • Maintenance
  • Requests

Unitmax OS Cloud

One backend · One Building Graph

WordPress module

Embed Unitmax OS functionality into an existing website.

IoT / BMS / meters

Connect sensors, meters and building systems.

External APIs & integrations

Connect existing software and third-party services.

12Connect, don’t replace

Unitmax OS works with the systems you already use.

A modern building already contains many systems.

Unitmax OS connects them into one shared context instead of forcing the operator to replace everything at once.

  • IoT devices
  • Smart meters
  • BMS
  • HVAC
  • Energy systems
  • Payment systems
  • Accounting
  • Government / official data
  • Cloud platforms
  • Document systems
  • Existing websites
  • External APIs

Your existing tools remain useful. Unitmax OS makes them work together.

13Modular by design

Start with one problem. Grow into the operating system.

You don’t need to digitize everything on day one.

Start with one clear use case and expand the platform as the building becomes more connected.

  1. Step 1

    Digitize

    Create the building structure.

    • Building
    • Spaces
    • Systems
    • Equipment

  2. Step 2

    Connect

    Add live information.

    • Meters
    • Sensors
    • IoT
    • Energy
    • External systems

  3. Step 3

    Understand

    Create context.

    • Analytics
    • Building Graph
    • AI

  4. Step 4

    Automate

    Turn understanding into action.

    1. Detect
    2. Understand
    3. Alert
    4. Create tasks
    5. Follow execution
    6. Learn from history

From a digital building to a building that helps manage itself.

14Timing

Why now?

  1. 01

    Buildings are becoming connected

    Smart meters, IoT and connected equipment generate more data than ever before.

  2. 02

    Energy matters

    Resource consumption and energy efficiency have become a daily operational priority.

  3. 03

    Building data is becoming digital

    Government, industry and commercial data are increasingly available through APIs and digital registries.

  4. 04

    AI has arrived

    AI can analyze documents, telemetry, history and events — but only when it understands their context.

AI is only as good as the building context it understands.

Unitmax OS creates that context.

15Already more than a concept

Built around real buildings.

15 real buildings are already represented in Unitmax OS — 13 in Ukraine and 2 in the Czech Republic.
