A seven-year, $60.5M NYSERDA impact evaluation of 654 buildings found vendor-reported savings only 48% verified overall — but FDD-only and OEM-controls-only vendors verified 0%, while ASO and software-overlay vendors verified over 100%. Here's the vendor-type table every AI-HVAC RFP should use.
SB 253's August 10 deadline and Taiwan's ISSB phase-in both require Scope 1/2 numbers that trace back to metered building data. Monthly-bill M&V won't clear third-party assurance — here's the 90-day fix.
The biggest 2026 threat to a credible energy-savings number is not a bad retrofit - it is an unaccounted non-routine event. As AI and volatile loads contaminate M&V baselines, IPMVP and ASHRAE Guideline 14 discipline is what protects pilot ROI. A practitioner playbook.
Your AI-HVAC or BaaS vendor's "20% savings" pitch is not a number until it is measured against a contractually-specified baseline using a named IPMVP option.
Meter-based, machine-learning measurement & verification ("M&V 2.0" / NMEC) has quietly become the default for whole-building savings claims, replacing the old twelve-points-of-billing-data regression.
Standards Why 88% of Smart Building Pilots Fail (And the Fix) Most pilot failures aren't technology failures — they're governance failures. A trial-based framework with IPMVP-grade gates changes the math.
Two things landed in the last nine months that change how anyone running a data center hall has to think about measurement and verification (M&V). First, the U.S.
Measurement & verification is quietly splitting into two worlds. The first is the old world of manual IPMVP Option C studies — engineers pulling utility bills, building regression models in a spreadsheet, and waiting months for a savings number.
Every AI-HVAC vendor pitch in 2026 cites "verified savings" and "IPMVP-aligned M&V." Almost none cite the two numbers that decide whether the verification actually held: CV(RMSE) and NMBE .
