Discipline 01 · KNX · ISO/IEC 14543
One KNX backbone. Every vendor on it.
KNX is the global open standard for building automation: a decentralised bus that links lighting, shading, HVAC, metering and scenes on one pair of wires, with 500+ manufacturers interworking. We pick the best product for each job, put them all on one system, and hand the owner a single interface — no vendor lock-in, no five separate apps.
A single KNX TP bus connects every device.
Each can talk to the others, so a ‘Welcome’ scene can set lights, climate and blinds together and the owner controls it all from one app.
Lighting control
Presence detection and daylight dimminglight only where, and only as much as, needed. Scenes for every mood and zone.
Shading & blinds
Automatic blinds for thermal comfort and glare control, reducing summer heat and winter heat loss.
HVAC & climate
Per-room demand control and scheduling — never condition an empty unit. The single biggest lever on running cost.
Energy metering
Per-unit consumption made visible and billable — the data finance needs and the basis for fair, transparent charging.
Scenes & schedules
One tap sets a whole zone — ‘Welcome’, ‘Away’, ‘Night’ — and schedules run the building when no one’s thinking about it.
Remote app
Control and check the building from anywhere — phone, office, or across a border. The whole system in one hand.
Everything the building does on one system
Each one is delivered, programmed and supported in house and designed to talk to the other four.
Why open beats proprietary
Best product for each job, from 500+ vendors no lock-in
Backward-compatible extend for decades, no rip-and-replace
Runs on a local bus no cloud single point of failure
KNX Secure — cybersecurity
A connected building is only secure when built right. KNX Secure encrypts and authenticates bus and IP communication, keeping systems open without leaving them exposed.
What the owner actually gains from KNX.
Measurable money saved
Up to ~30% lower energy use moving to EN 15232 Class A — aligned with KENAK and near-zero-energy rules, straight onto the operating P&L.
Time given back
Faults, leaks and consumption surface on one dashboard with remote diagnostics — fewer call-outs, faster fixes, less firefighting.
Value that compounds
Comfort and reliability turn residents and guests into repeaters and protect the rating — the cheapest marketing a building has.

“Lower running costs lift net operating income and asset value — and a Class A energy rating is a selling point on every unit. Sustainability isn’t a cost centre here; it’s a line on the return.”

Give us your plans and we’ll cost them as if the job is already ours — one specification and budget across all five disciplines, phased to your programme. Not a quote to compare. A plan for the building you actually want.
