Net zero isn't a slogan. It's a meter, a benchmark, and the work in between.
“cut the bill, hit the target”
Most estates have an EPC certificate that doesn't match the bill. Sensors close that gap — continuous kWh, real-world performance vs design, and the savings that come from heating only the rooms you're using.
Three capabilities, one feed.
Continuous metering
Per site and per zone (where sub-metered) — electric, gas, heat. Hourly uplink, daily totals, monthly rollups ready for the report.
Sector benchmarking
Your kWh/m²/yr against the 317-row CIBSE TM46 benchmark library. Top-quartile flags surface where the waste is.
Boiler control included
Where the savings actually happen. Retrofit timeclock control means the boiler stops firing into empty rooms. See /control.
Across surveyed schools: 45% of boiler hours wasted on empty rooms before control was added. The biggest single saving in any estate.
today
920 kWh electricity + 1,700 kWh gas
Gas heating is 62% of today’s carbon.
Total carbon across all fuels. DEFRA 2026 — electricity 0.207, gas 0.183 kg/kWh.

Where the carbon comes from.
Two fuels, one carbon total. Gas heats the building; electricity runs everything else.
190 kgCO₂e · runs lighting, power, cooling
311 kgCO₂e · space heating & hot water
Gas is 62% of the carbon from 65%of the energy — heating is where the decarbonisation gain is.
Designed a C — running an E.
EPC rates the design. DEC rates how the building actually runs. The gap is the opportunity.
Operational use is running 29% over the design rating.
90-day running rate, all fuels. Operational rating benchmarked to CIBSE TM46 typical school.
It doesn’t stop at the screen.
The reading is checked against the rulebook on an orchestration engine. When it’s out of band the job is created, sent to the right person and chased until it’s signed off — and every step is logged. Here’s a real flow for net zero & energy.

The audit trail it builds.
One sensor stream. Multiple rulebooks. Each row links to the full entry in the Standards matrix.

Short call. We’ll scope what a v1 deployment looks like and walk through the standards we can prove the day it goes live.
