Controlled Environment Agriculture

In a controlled environment, the utilities are not overhead — they are the growing recipe. Irrigation volume, lighting load, heating and dehumidification all move together, and a monthly total hides every one of the interactions between them. Continuous metering makes the recipe measurable, and makes a fault at 2 a.m. something you find out about at 2 a.m.

Climate is the first thing we meter, because it is the thing with the shortest fuse. A zone that spends three hours under setpoint on a January night has cost a week of growth, and the loss is already banked by the time anyone walks the range in the morning. Temperature and humidity sensors on the zone, an alert threshold either side of the setpoint, and a text message — that is the whole intervention, and it is usually the reason the system gets bought.

Irrigation is the second. Recipes are set per zone and then trusted, and a solenoid that does not quite close will follow the recipe on paper while delivering something else entirely. Flow metering per zone gives you litres delivered against litres intended, every day, per zone — which is a water number, a fertigation number and an early warning about a valve, all from one meter.

Energy sits underneath both. Lighting and dehumidification are the two largest loads in most operations and they are strongly scheduled, which makes them the easiest place in any facility to see a demand peak and move it. Gas for heating behaves the same way: baseload creep in a boiler is invisible on a monthly bill and obvious on a sixty-second trace.
