22 kW drive on line two. The vibration trend is the entire reason it is monitored.

Frozen container, minus eighteen the whole way. The log is the only thing that survives the journey.

Sat beside a busy road. Mornings are worse than I expected. Still air holds everything in until the sun gets up.

One multi-deck on the chilled aisle. I am trying to work out whether the shrinkage is the case or the staff.

Spindle load and utilisation. Mainly useful when quoting.

Cycle counts, utilisation, and every short stop. Quoted capacity and actual capacity have never been the same number.

Compressed air costs us more than lighting and heating together. This is where I prove it to people.

Incoming supply for the whole building. Tenants ask what happened. Now I can tell them.

Dewatering the pit. If this stops, work stops, so it gets watched properly rather than checked on.

Thirty seven degrees, tight tolerance. A short excursion overnight invalidates a week of work and you would never know.

96 kWp across the warehouse roof. I check yield against irradiance most mornings. When it drifts below where it should be, the panels want washing.

Feed pump on the boiler. It threw a bearing in March and took the boiler down with it. Now it is watched.

Monitoring at the board. We had equipment failing and nobody could say why. Turned out to be sags, not the equipment.

Clean baseline on campus. We hold the roadside numbers up against this one.

Small server room on a precision unit. Honestly this is here so I know how much headroom is left in the hottest week of the year.

Vapour around the depot, with extraction status right next to it so I can tell which one is the problem.

30,000 litre diesel tank. Days of stock is the number I actually look at. Deliveries land here too, so I can see whether what was invoiced matches what arrived.

Frost watch through the season. One night is all it takes.

18 kWp teaching array. Students can see where the losses go instead of taking my word for it.

Air handler on the third floor. Half of this is settling arguments about whether it is actually running.

One residential zone of a distribution network, metered on its single inlet, with the volume billed inside the zone alongside it. The gap between the two is non-revenue water, and splitting a network into zones is what turns one town-wide loss figure into somewhere to send a crew.

Main cold store, product for export. Since we started logging door time the arguments stopped.

A commercial zone where the pipework is sound and the loss is still large. Water that reaches a customer and is never billed follows the demand curve instead of running all night, which is why two zones can lose the same share and need entirely different work.
