Facility Energy Benchmark Tool

The tool benchmarks annual energy spend intensity in pounds per square metre against broad sector ranges. These are practical planning benchmarks rather than formal NABERS, DEC, or TM46 compliance outputs. The sector baseline is adjusted for operating hours and, more lightly, by heating type because all-electric buildings and heat pump-led sites can carry different tariff exposure even when delivered energy efficiency is strong.

A percentile estimate is then assigned within the benchmark range and translated into a simple A-G band. A and B represent upper-performing facilities, C and D sit around the main body of the market, and E to G indicate materially above-typical spending for the building type.

Improvement priorities are selected from a ruleset based on sector profile and current performance gap. For example, hotels and restaurants are more likely to surface hot water, ventilation, and controls opportunities, whereas warehouses often prioritise destratification, door-management losses, and zoned heating strategy.

Use the output as a triage tool. A proper energy review should still look at half-hourly data, setpoint scheduling, controls logic, seasonal weather correction, ventilation loads, occupancy data, and whether non-heating process loads are inflating site spend beyond the sector benchmark assumptions used here.
