Ian Jeffries, Managing Director, EEVS

Headline
M&V is not just a technical process—it’s a strategic governance tool that manages risk, builds trust, validates savings, and makes decarbonisation investments credible. 

Key Messages

1. Why M&V matters - “If you’re not measuring it, you can’t manage it.” M&V provides evidence-based savings data essential for sound investment decisions. 

2. The problem M&V solves - Energy savings cannot be measured directly—there’s “nothing to measure.” M&V solves this through mathematical modelling

3. Strategic value – M&V provides the governance needed to manage risk, deliver confident, credible reporting, and an evidence-based, investable market for energy and carbon saving projects. 

4. Market challenges – Low awareness among senior leaders; perceived as purely technical; credibility gap with suppliers seen to be ‘marking their own homework’. 

5. Call to action to drive M&V adoption – Reframe M&V as a strategic enabler, allocate budget early, use independent verification, educate decision-makers, and celebrate proven results. 

Hilary Wood, Director, EEVS

Headline

Professionalising M&V through recognised standards, qualifications, and training is key to building trust, consistency, and capability across the sector.

Key Points

1.      Why professionalisation matters - Without robust standards and training, savings remain “just estimates,” undermining credibility and uptake.

2.      Frameworks and standards - IPMVP provides transparent, consistent methods for evaluating savings, requiring pre-project M&V plans and independent verification for financial integrity. 

3.      Qualifications - PMVA (foundation) and PMVE (advanced) courses build practitioner capability; EVO’s updated certifications aim to raise the bar. 

4.      Technical essentials - Measurement boundaries and IPMVP options (A, B, C, D) ensure methods match project complexity

5.      Future direction - Integrating digital tools and shared data frameworks will make M&V faster, scalable, and more transparent—but standards and skills must evolve first.

Headline

Salix is evolving its approach to Measurement & Verification (M&V) in public sector decarbonisation funding - establishing a new set of basic M&V requirements and, over time, working towards best in class M&V to ensure delivery of transparent and credible carbon savings within the public sector.

Key Points

1.      Context and scale - Salix administers £3 billion in public funding for carbon reduction projects under the Public Sector Decarbonisation Scheme (PSDS), requiring savings reporting for three years post-completion. 

2.      Current state (“Good”) - Previously relied on single annual energy figures with minimal guidance; now introduced baseline regression, monthly data requests, and non-routine adjustment reporting. 

3.      Future ambitions (“Better” and “Best”) – Move toward IPMVP-aligned practices, including:  Sub-metering and higher-resolution data (half-hourly). Independent verification by qualified M&V professionals (PMVA/PMVE) with regular stakeholder engagement and governance improvements.  Allocating up to 3–5% of project capitalfor M&V (currently <1%) and potentially linking grant disbursement to verified savings reports. 

4.      Challenges faced:  Data gaps, inconsistent terminology, resource constraints, and varied carbon literacy among recipients. Mid-cycle implementation caused confusion; diverse project types complicated standardisation. 

5.      Successes and lessons - 80% return rate for Phase 3 reporting forms—a major improvement. Positive engagement and growing awareness of M&V’s value.  Enhanced data quality enables better analysis and future benchmarking. 

6.      Strategic importance - Robust M&V underpins credible decarbonisation, informs future policy, and builds a transparent market for energy efficiency investments.

Headline Message
AI is reshaping M&V from a manual, meter-heavy activity into a predictive, data-driven discipline — but credibility, transparency, and human oversight remain essential for trust.

Key Points

AI’s role in M&V - AI is past the hype stage and becoming integral to energy management. The key question isn’t whether AI replaces humans, but how professionals adapt. M&V’s core purpose is creating credible agreement around an unmeasurable number — energy savings — not just producing calculations.

From legacy to AI-native approaches -Traditional M&V depends on submeters, fragmented data, manual handling, and slow verification. AI-native methods use existing utility data, automated data onboarding, and machine-learning models to identify inefficiencies and predict savings. Example: A UK retailer saved £170k/year after AI flagged a chiller setpoint issue using only main-meter data.

Themes from breakout discussions

1. Credibility: AI outputs must be transparent, repeatable, and comparable with traditional methods.

2. Human roles: Professionals shift from number-crunching to sense-checking, interpreting anomalies, validation, communication, and governance.

3. Vendor expectations: Cybersecurity, accountability, and explainability (or interpretability) are essential.

4. What remains human: Relationship-building, bias management, contract alignment, and decision-making.

5. Key challenges: Black-box models raise auditability concerns; standards are needed for transparency and verification. Trade-offs remain between low-cost, probabilistic insights and high-cost granular submetering.

Overall takeaway - AI won’t replace M&V professionals — but those who fail to adopt and oversee AI tools risk being left behind as the sector becomes more strategic and data-driven.
