Heating — In a 15 °C hall, one extra degree adds 6.7% to the heating bill. Loksa keeps those degrees off your bill.. ➤
Ventilation — Every extra cubic metre of air pulled out of a heated hall is heat you bought and threw away — on top of what the fans themselves cost. Off, at 30%, at full: you see the level it is actually running at. ➤
Lighting — An aisle nobody walks, a hall lit through lunch, a switch nobody flipped on Friday — each too small to notice, all of them running for months. All of it is paid for, and none of it produced anything. ➤
Left running — Compressors, pumps, extraction, conveyors: a machine that is on but doing nothing costs nearly as much as one doing work. On a meter the two look identical — Loksa tells them apart, while it is still running. ➤

A control system runs equipment. It was never built to find waste.
A thermostat exists to hold one point at one number. It does that job perfectly while the building around it runs four degrees too warm — because the rest of the building was never its business.
Most control systems store little or nothing. Without history there is no trend, no comparison between this winter and last, no proof — only the number on the panel right now — no way to know whether it is still true.
Heating knows nothing about the gate left open. Lighting knows nothing about the empty aisle. No controller knows that a machine has been running with nothing to do since lunch.
