CRREM Stranding Risk Calculator

Find your building's CRREM stranding year in minutes rather than spreadsheets. Compare carbon intensity against CRREM pathways, quantify transition risk and see the Green Premium you protect by acting early — across UK, EU, GCC and US assets.

The challenge

The Carbon Risk Real Estate Monitor (CRREM) provides carbon-intensity pathways aligned with the Paris Agreement. Buildings that exceed these pathways face increasing risk of stranded asset status — affecting valuations, financing, insurance and disposal. Many asset owners rely on manual XLS workflows and have limited visibility of where their assets sit relative to the pathway.

How Intelli-BuildAI helps

Intelli-BuildAI calculates indicative carbon intensity for commercial buildings, compares performance against relevant CRREM pathways, and estimates the year at which the asset may exceed the pathway if no action is taken. The scan also identifies practical measures to reduce stranding risk and the asset value protected by acting early.

  • Indicative carbon intensity calculation (kgCO₂e/m²/yr)
  • CRREM pathway comparison by asset type and geography
  • Estimated stranding year (indicative)
  • Online alternative to manual CRREM spreadsheet workflows
  • Carbon reduction gap quantification
  • Retrofit measures ranked by carbon impact
  • Board-ready stranding risk summary

How the stranding assessment runs

  1. 1

    Establish measured consumption

    Utility bills, EPCs, BMS exports or meter data are ingested, with each extracted value carrying a confidence score and a reference back to the source document.

  2. 2

    Convert to carbon intensity

    Consumption is combined with floor area and the regional emission factors for the asset's grid, giving carbon intensity in kgCO₂e/m²/yr rather than a fuel-blind energy figure.

  3. 3

    Select the applicable pathway

    The CRREM pathway is chosen by asset type and geography, so an office in London and a mall in Dubai are each judged against their own envelope.

  4. 4

    Locate the crossing point

    Intensity is plotted against the pathway to give the indicative year the asset exceeds it — restated automatically as the data behind it improves.

  5. 5

    Rank measures by carbon impact

    Each retrofit measure is scored on how far it moves the stranding year, alongside capex and payback, so carbon and capital are traded off explicitly.

  6. 6

    Report to the board or lender

    Outputs assemble into a stranding-risk summary with the assumptions register attached, and can be disclosed through a scoped, expiring read-only lender portal.

Frequently asked questions

What is CRREM?

The Carbon Risk Real Estate Monitor (CRREM) is a research tool that defines science-based carbon-intensity pathways for commercial real estate by asset type and geography, aligned with the Paris Agreement targets of 1.5°C and 2°C.

How is the stranding year calculated?

Carbon intensity is derived from metered consumption, floor area and regional emission factors, then plotted against the applicable CRREM pathway. The stranding year is the point at which the asset's intensity crosses that pathway.

Is the CRREM stranding year a definitive figure?

No. The stranding year is an indicative estimate based on current carbon intensity and the CRREM pathway. It does not account for future grid decarbonisation, building improvements or regulatory changes, all of which affect actual stranding risk.

Which CRREM pathways does Intelli-BuildAI use?

The platform references CRREM v2 pathways for relevant geographies and asset types, covering UK, EU, GCC and US assets. The applicable pathway is selected based on building location and use.

How is this different from the CRREM XLS tool?

The inputs are read directly from utility bills, EPCs and BMS exports rather than typed in, results update as data improves, and every input is flagged verified or estimated in the evidence register — removing the manual spreadsheet step while keeping a full audit trail.

What do I do once I know the stranding year?

The scan ranks retrofit measures by carbon impact and shows how each moves the stranding year, building a costed pathway back inside the CRREM envelope — with payback, NOI uplift and the Green Premium value protected by acting early.

What data do I need, and what does it cost?

A single utility bill, EPC or BMS export and a floor area is enough to start, and the first building scan is free, returned within 48 hours.

Start with one building.
