Building EUI Benchmarking Tool

Calculate Energy Use Intensity from metered consumption and verified floor area, then benchmark against CIBSE TM46 categories, ASHRAE references and RIBA 2030 targets — so you know whether an asset is a leader, a laggard or a liability.

The challenge

EUI is the single most-used metric in building performance, yet most reported figures are unreliable: gross vs net floor areas are mixed up, part-year bills are annualised incorrectly, and landlord vs tenant consumption is conflated. Decisions made on bad EUI figures misdirect capital.

How Intelli-BuildAI helps

Intelli-BuildAI computes EUI from source evidence — utility bills, meter exports and RICS-classified floor areas — and flags every input as verified or estimated. The result is benchmarked against CIBSE TM46 building categories, ASHRAE references, RIBA 2030 Climate Challenge targets and regional medians, with a confidence score and an indicative Green Premium uplift attached to closing the gap.

  • EUI calculated from source bills, not self-reported figures
  • Verified vs estimated flag on every input
  • CIBSE TM46 category and ASHRAE benchmarking
  • RIBA 2030 Climate Challenge target comparison
  • Gap-to-target quantification in kWh/m²/yr and £/yr
  • Green Premium uplift attached to closing the gap
  • Portfolio ranking to prioritise worst performers

Frequently asked questions

What is a good EUI for a commercial office?

RIBA 2030 targets 55 kWh/m²/yr for offices; typical UK stock ranges from 100–250 kWh/m²/yr. The right benchmark depends on building type, servicing strategy and operating hours — the platform selects the appropriate CIBSE TM46 category automatically.

Does the tool use GIA or NIA?

Both are tracked. EUI is reported against GIA by default, consistent with CIBSE TM46 and CRREM conventions, and the floor-area source (imported, zone-calculated or manual) is recorded in the evidence register.

Which standards are used for benchmarking?

CIBSE TM46 categories and ASHRAE references are used as the primary benchmarks, with RIBA 2030 targets and CRREM carbon pathways applied alongside where relevant to the asset type and geography.

What data do I need to provide?

Utility bills, meter exports, EPCs or BMS data plus a floor area. A single bill is enough to start; additional evidence raises the confidence score on the result. Uploaded documents are read by the ingestion engine, with extracted values presented for your explicit approval before they touch the project.

How does EUI relate to the Green Premium?

Closing the EUI gap reduces operating cost, which lifts NOI. Capitalised at your cap rate, that uplift is the indicative Green Premium — a screening figure that formal valuation must confirm.

Can I benchmark a whole portfolio?

Yes. Portfolio views rank buildings by EUI, gap-to-target and estimated saving value, so capital is directed at the assets where intervention returns most.
