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.
Lighting control
Presence detection and daylight dimming — light 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 built in
A connected building is a cyber-risk if it’s built carelessly. KNX Secure adds authenticated, encrypted communication on the bus and over IP — so the same openness that prevents lock-in never becomes an open door
What the owner actually gains from KNX.
Finance — 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.
Operations — time given back
Faults, leaks and consumption surface on one dashboard with remote diagnostics — fewer call-outs, faster fixes, less firefighting.
Reputation — 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.
