“If you cannot measure it, you cannot improve it.”

“When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.”

Lord Kelvin (William Thompson)

Our sub-metering solutions help organisations understand how much and when energy is being consumed beyond the main fiscal meters. Making energy consumption transparent and easy to understand will support the identification of energy waste.

Sub-meters are installed downstream of main fiscal meters to provide more granular energy consumption (or generation) detail of individual building zones and services e.g. chillers, boilers, AHU, lighting, solar PV, heat pumps etc.

Sub-metering can be used to support investment decisions before and after implementation e.g. energy-efficient lighting, building fabric upgrades etc.
