We design, install and commission open-protocol BAS/BMS platforms that connect HVAC, lighting, metering and auxiliary equipment into one network. Open standards keep you free of vendor lock-in, simplify maintenance and lower operating costs.

What we do

Open-protocol architecture

Every device speaking the same language.

  • Native BACnet/IP and MS/TP across chillers, boilers, RTUs and VAV boxes
  • Modbus integration with power meters, VFDs and generators
  • Equipment from different manufacturers on one platform

Custom web-based dashboards

Your building at a glance, from any browser.

  • Colour-coded floor plans with live temperature, humidity and airflow
  • Central holiday, event and occupancy scheduling
  • Historical trend logs for energy use and runtime

Field hardware deployment

Accurate sensing and precise control.

  • Direct digital controllers (DDC) with modular expansion
  • High-accuracy airflow, pressure and CO₂ sensors
  • Electronic modulating valves, smart dampers and actuators

Common questions

Yes. We retrofit older buildings with open-protocol DDC controls, using wireless sensors or existing wiring where it makes sense to limit disruption.
