for smarter buildings

Anonymised BMS case study

Trend IQ controller upgrade planning example

Before replacing controllers, the important work is understanding real I/O, strategy logic, panel space, comms, power, drawings and what the building cannot afford to lose during changeover.

Checks carried out

Evidence before recommendations.

  • Map existing analogue inputs, digital inputs, outputs and critical interlocks.
  • Check panel space, DIN rail, power, labelling and wiring condition.
  • Create a migration sheet that separates like-for-like points from improvement opportunities.
  • Plan staged works so plant operation and tenant impact are controlled.

Output

What the client should receive.

A migration pack that gives the client, contractor and BMS engineer a common view of what must be moved, tested and signed off.

This style of case study is deliberately anonymised. The aim is to show the engineering process without naming sites, exposing live systems or making unsupported savings promises.
