Retrofit ROI Calculator

Model commercial retrofit ROI in minutes — capex, utility savings, carbon reduction, NOI uplift and the Green Premium, with every measure ranked by payback for board-level capex decisions.

The challenge

Commercial real estate owners and asset managers face competing retrofit priorities with limited capital. Without structured analysis, investment decisions are based on incomplete information, leading to missed opportunities and suboptimal capex allocation.

How Intelli-BuildAI helps

Intelli-BuildAI analyses available building data to produce a structured retrofit priority list. Each measure is assessed for indicative energy saving, carbon reduction, capex and payback period, and the resulting NOI uplift is capitalised into an indicative Green Premium. All figures are indicative and require engineering validation.

  • Retrofit measure identification from available data
  • Indicative capex and energy saving estimate per measure
  • Indicative carbon reduction per measure
  • Estimated simple payback period
  • NOI uplift and Green Premium value estimate
  • Priority ranking by ROI and carbon impact
  • Board-ready next-actions summary

Frequently asked questions

What does the retrofit ROI calculator model?

Capex, utility savings, carbon reduction, payback, IRR, NPV, NOI uplift and the indicative Green Premium for each measure, ranked so the highest-return interventions surface first — with a sensitivity matrix showing how returns move as tariff and cap-rate assumptions change.

Is it free to use?

Yes — the first building scan is free. Upload a utility bill, EPC or BMS export and the retrofit priority list is returned within 48 hours.

Where do the savings figures come from?

From the building's own physics-based load model — envelope, gains, climate and operation — not generic percentage assumptions. Measures are evaluated in sequence against the evolving model so interactions are handled rather than double-counted, and every figure links to its assumptions.

Are the ROI figures reliable?

They are indicative and bounded by input quality, which the platform states explicitly: each result carries a confidence score and every input is flagged verified or estimated. Estimates require validation through detailed survey, metering and engineering design before capital commitment.

What measures does the scan cover?

HVAC plant and controls, lighting, building fabric, metering and renewables — with equipment selections drawn from a catalogue of real manufacturer products including sizing, efficiency and indicative pricing.

How is the Green Premium calculated?

Utility savings are converted to NOI uplift and capitalised at your cap rate to produce an indicative asset-value effect — a screening figure, not a formal valuation.

Can the output support a funding application or lender review?

Yes. The funding module matches grants, loans and incentives to your region and measures, and for debt-financed projects the platform produces lender-facing outputs — bankability scoring, stress testing and a read-only lender portal — on the same underlying data.
