Savings Verification
Independent confirmation of your scheme’s energy saving performance can be key to building trust in supplier claims. EEVS provides the highest quality performance analysis and verification services to hold suppliers to account.
What we do
Once an energy saving scheme has been installed, EEVS acts as independent auditor and performance verifier – either confirming that the investment is delivering the level of savings expected, or uncovering performance-related shortcomings.
Our impartial and objective performance evaluation is particularly important where savings targets, incentives or performance guarantees are included as part of the deal, or where a client needs greater certainty that reported savings have been calculated in accordance with agreed terms.
EEVS-verified figures can also be used as the basis for payment.
Typical schemes we work on include:
- Performance-based contracts Energy Services Agreements (ESA) or Energy Performance Contracts (EPC) incorporating savings performance guarantees running for 7+ years
- Third party funded schemes (c£5m+) where the cost savings are expected, as a minimum, to cover the repayment costs
- Large single sites or campus sites where a range of energy efficiency and renewable technologies are deployed to drive savings
- IPMVP International Performance Measurement & Verification Protocol has been specified as the technical standard governing the energy savings determination and reporting process.
Why verify savings?
Technical complexities relating to energy saving performance measurement means it is good practice – especially for larger schemes – to seek independent verification of a supplier’s performance claims. These principles have been set down by the long-established global good practice protocol IPMVP of which EEVS is the UK’s leading practioner.
Key benefits to having scheme performance independently checked and verified include:
- Trusted savings – building a successful long-term supplier partnership based on robustly proven, value-for-money results
- Managed risk – a key safeguard to help ensure suppliers are held to account and are not ‘marking their own homework’ unchallenged
- Performance-focused – ensuring a results-driven ethos is embedded within all of your supplier arrangements
- Strong leadership – active supplier management to drive greater value and sustained performance over time.
- Confident communications – externally audited results are more credible and easier to communicate to key stakeholders
- ISO50001 – evidencing a ‘plan-do-check-act’ ethos and a commitment to demonstrable energy improvements.
How we work
As part of every supplier audit and savings verification process, EEVS undertakes a detailed qualitative and quantitative assessment of all the methodologies (e.g. IPMVP adherence) and calculations used to generate a savings figure. This typically involves a full review of all relevant contractual documentation, datasets and analytical processes.
Issues that we often uncover through this process include:
- Contractual breaches and non-compliance
- Incorrect attribution of ‘savings’ e.g. failing to account for unrelated changes or events
- Calculation errors and incorrect assumptions
Following the audit, we issue a formal Savings Verification Report containing the EEVS-verified savings figure(s) attributable to the scheme for the period under review. This audited and verified figure may then be used as a basis for performance-related payment.
For many of our client schemes, this process is repeated either annually or quarterly.
