Intelligence,
Without
Starting Over.
Brownfield integration adds IoT, modern controls and analytics to your existing building — without the cost or disruption of full replacement.
What Is Brownfield Integration?
A brownfield building is any existing structure with installed mechanical, electrical and control systems — which means virtually every building over five years old.
Brownfield integration is the practice of layering new intelligence on top of those existing systems, rather than tearing them out and starting over. We add IoT sensor networks, protocol translation gateways, edge computing nodes and analytics dashboards to the infrastructure you already own.
The result: a building that behaves like a modern smart building — at a fraction of the cost.
60–80% Less Cost
Versus full system replacement. Preserve your capital investment.
Zero Disruption
Buildings stay fully operational throughout. No downtime required.
3–7 Day Install
Typical IoT overlay deployment window, including commissioning.
18–24 Month ROI
Typical payback period driven by energy savings and operational gains.
The Brownfield Challenge
Legacy Protocol Chaos
Buildings accumulate systems from different eras and manufacturers — each speaking its own protocol. BACnet, Modbus, KNX, OPC-DA, proprietary. Getting them to share data is a specialist skill.
Zero Downtime Constraint
Hotels, offices and hospitals cannot stop operations for a building upgrade. Every intervention must happen around live occupancy, often in the early hours, with instant rollback if anything goes wrong.
No Single Source of Truth
Mixed-vendor systems mean fragmented data, incomplete drawings and no unified view. Decisions get made on guesswork. Our audit creates the first complete, accurate picture of your building’s systems.
Our 5-Step Integration Process
Every brownfield project follows the same disciplined sequence — designed to eliminate surprises before they reach your building.
Discovery Scan
Full audit of every installed system — BMS, HVAC, lighting, access control, metering. We produce the first accurate, unified asset register your building has ever had.
Protocol Mapping
Every communication language in the building is identified and documented — BACnet, Modbus, KNX, OPC-DA, proprietary. We define the translation matrix before any hardware is ordered.
Integration Design
IoT overlay architecture designed from scratch — gateway placement, sensor mesh topology, edge node sizing, and data pipeline to the analytics layer. No generic templates.
Remote Lab Validation
The full integration is pre-staged and tested in our Dubai facility before a single engineer arrives on site. Every sequence verified. Every failure caught in the lab, not your lobby.
Live Deployment
A 3–7 day zero-disruption install. Because the integration was fully validated in the lab, on-site time is pure execution — no debugging, no surprises. Instant rollback capability maintained throughout. Building stays 100% operational.
Protocol Intelligence
The single biggest technical challenge in brownfield integration is the tower of Babel problem — every decade of building automation history left behind a different communication protocol.
We speak all of them. Our gateway and edge software stack translates between BACnet, Modbus, KNX, OPC-DA, LON and DALI simultaneously, presenting a single unified data model to the analytics and control layer above.
Your systems don’t need to agree with each other. They just need to talk to us.
These six protocols cover 95%+ of building automation systems installed in commercial real estate since 1990.

IP · MS/TP · EthernetASHRAE 135 open standard. The most common protocol in modern commercial BMS — Tridium, JCI, Siemens, Honeywell.
Modbus TCP
TCP/IP · RTU · ASCIIIndustrial workhorse. Ubiquitous in energy meters, drives, chillers and older PLC-based plant rooms.
KNX
TP · IP · RFEuropean standard for building control. Dominates lighting, shading, and room-level HVAC in high-spec commercial and residential.
OPC-DA
DCOM · WindowsLegacy Windows-based standard found in Siemens APOGEE and older SCADA-class BMS. We bridge it to modern IP stacks without replacement.
LON / LonWorks
TP-78 · IP-852Echelon peer-to-peer network. Common in buildings installed 1995–2010. Frequently found in Siemens and Carrier systems.
DALI
DALI-2 · IEC 62386Digital Addressable Lighting Interface. The standard for individual lamp addressability — zone control, occupancy dimming, emergency circuits.

In the Real World
Every project in our portfolio started with an existing building, a stack of legacy systems, and a client who had been told replacement was the only option. Browse our completed projects to see what brownfield integration actually delivers — in numbers, not promises.
