Proof — What AI in Buildings Actually Returns, According to People Who Don’t Sell It
Three numbers from named third-party sources. One market-sizing band from the consulting majors. Source links visible in every tile because vendor self-report is not evidence.

Three Tiles. Three Sources. Three Different Asset Classes.
Tile 1 · Institutional Asset Owner
708%
ROI on AI-led optimization, single Birmingham office asset
Reported by a UK institutional investor managing a multi-billion-pound real-asset book. Documents the energy-cost reduction and carbon impact from an AI-led HVAC and occupancy optimization deployment on a single grade-A office building. Cited as third-party evidence by an independent AI-in-CRE research consultancy.

Tile 2 · Cross-Consultancy Consensus
14% / 91%
Energy-cost reduction / Operational-improvement reporting
Convergent reporting across the major real-estate advisory firms and a global building-management OEM. 14% median energy-cost reduction across deployed AI-HVAC pilots. 91% of surveyed CRE leaders report operational improvements from AI tooling in 2025–2026. Two different cuts of the same underlying market; the consensus is what makes it usable as a procurement baseline.

Tile 3 · Multi-Asset Retail Portfolio
85%
Anomaly-detection accuracy, 50-mall retail portfolio
Reported across a 50-asset US shopping-mall portfolio using AI-driven fault-detection and diagnostics on HVAC and refrigeration loads. 85% precision on actionable anomalies — the operationally relevant number is not detection rate but actionability, because false positives are the failure mode that kills FM-team adoption.

Market-Sizing Band · Where the spend is going
$99.2B (2024) → $197.3B (2030) at 12% CAGR.
Global AI-in-buildings market sizing, consensus from independent analyst houses including the AI-vertical research desks. The doubling happens during a 19-month window in which EU AI Act Article 26 deployer obligations move from text to enforcement and SBTi Buildings Interoperability operationally locks Q1–Q3 2026. The size of the market is not the story. The shape of the buyer is — they need a compliance pack on day one, not a year-three roadmap.
Methodology: Median of three published 2024-baseline analyst sizings with 2030 forecast horizons. Excluded sizings that include AI data-center construction (different buyer, different cycle). Cross-checks: Blott AI / AI Real-Estate Market · Verdantix Smart-Building Research
Why This Page Looks Like This
Vendor-cited ROI is not evidence. Vendor-self-reported deployment count is not evidence. A logo wall is not evidence. The trust contract for an AI-in-buildings stack in 2026 is the same contract IPMVP applied to retrofit attestations in 1997: show the source, name the asset class, and let the reader open the link.
Each tile above carries: a third-party source link, a named asset class, and a number that survives a 30-second look at the underlying methodology. The market-sizing band carries three independent forecasts and a methodology disclosure. The page updates within seven days when a source moves.
If a competing AI-in-buildings vendor cannot do this on their own proof page, that is the proof.
Ask the Stack a Verifier Question
“Could my asset return 14% with these constraints?” “Is the 85% anomaly precision realistic for my refrigeration portfolio?” The IPMVP and Code Keeper agents are wired up to answer with show-your-work attribution.
