(00)Approach

We guide building owners and architects towards high-performing, durable buildings — with installations that are reliable, compliant and simple to operate.

(01)Engineering

Our craft, end to end

Neutral advice, design, tendering and supervision: a single thread from brief to handover.

01

Owner's engineering

Assistance to the building owner (BAMO): neutral advice and clear, objective decision structures.

02

Controls design & tendering

Vendor-neutral control system concepts and tender documents. Clear, detailed drawings and transparent comparison between integrators.

03

BMS / EMS architecture

BACnet · KNX · Modbus integration. Centralised supervision for simpler, more sustainable operation.

04

Audit & consulting

Analysis of existing control installations, energy-saving potential and renovation strategy.

05

Tool development

Custom software and electronic tools that simplify controls engineering and integration.

06

Integration & commissioning

Controller programming, functional testing, commissioning and operator training.

(02)Innovations

Tools we build ourselves

Where off-the-shelf software stops, we build our own software and electronics — to make engineering more reliable and MCR integration faster.

This technical independence delivers precise, traceable results that are reproducible from one project to the next.
