Building automation

HVAC, lighting and energy, controlled as one system.

A building management system is only as useful as the plant it can see and genuinely control. We integrate HVAC, lighting and metering on open protocols so a building can be operated, and its energy use understood, from one place.

Our scope

What we do on these systems.

  1. 01Survey existing plant, controls and metering to establish what can be integrated and what must be replaced
  2. 02Design the control architecture (controllers, field devices, network segments and head end) around how the building is operated
  3. 03Specify open, documented protocols at every supplier boundary so the estate is not tied to a single manufacturer
  4. 04Integrate HVAC, lighting, metering and other building services into one control and monitoring layer
  5. 05Segregate building-control networks from corporate IT, with defined and managed interfaces where data must cross
  6. 06Commission control loops and cause-and-effect logic against the design intent, and record the results

Platform

What the system does.

  • HVAC plant controlled to schedules and setpoints that reflect actual occupancy
  • Lighting control driven by occupancy and daylight rather than timers alone
  • Sub-metered energy consumption visible by system, floor or tenant
  • Alarms graded and routed so plant faults reach the right people before occupants notice
  • Trend logging that supports fault-finding and energy analysis over time
  • Open-protocol integration so equipment from different manufacturers operates on one platform
  • Building-control networks segregated from corporate IT, with defined interfaces where data must cross
  • Safe default states for plant on controller or network failure
