Measurement and Verification

energy measurement

Measurement & Verification is at the heart of all types of Energy Performance Contract. This is the basis of any commitment to results, and it is the only way to permanently validate the contractual performance.

Methods of measurement and verification of energy enable you to:

 

– Identify the real impact of energy saving actions.

– Assist the client in his decision, he knows where and how to operate.

– Ensure objective data for the customer and the operator .

– Reduce the economic and legal risks associated with the contract and to facilitate its monitoring.

 

Improving the Energy Efficiency ( AAEE ) Actions which provide a gain measurement, in most cases , is complex. Indeed, that may immediately , explain the reasons for which an annual energy consumption curve takes a particular form ?

Ensuring improved energy efficiency requires to understand and integrate the causes of these variations, so that the after-work results can be validly compared. It is impossible to directly measure a lack of consumption in a variable context.

It is impossible to compare like with like ! We thus offer Measurement and Verification procedures proven in real life.

EVO

EVO is a nongovernmental nonprofit organization devoted entirely to create protocols for measuring and verifying the performance of energy efficiency projects.

EVO is a non-profit organization formed by a group of experts and people interested in the development and promotion of the use of protocols, standardized methods and tools to quantify and manage the risks and performance benefits associated with projects in energy efficiency, renewable energy , as well as projects to reduce water consumption .

EVO is the only private non-governmental organization (NGO) non-profit, recognized worldwide, that provides tools on the measurement and verification used to increase the efficient use of natural resources. Our vision is a global market that adequately assesses the effective use of natural resources, and employs efficiency in end-use of resources as a viable alternative to new energy

The CPE reference

EVO’s IPMVP protocol is mentioned in Annex IV of Directive 2006/32/EC on end-use energy and services.

  • The IPMVP is the most widespread Measurement and Verification Protocol in the world, by simplifying the practical and important elements of its rival ASRAHE 14, 2002.
  • The IPMVP is flexible and pragmatic as it applies to a wide variety of projects without compromising costs.
  • The protocol is auditable and enforceable.

MEEDDM chose IPMVP as a methodological framework for CPE after a study funded and monitored by ADEME.

Principles

Evaluate energy consumption

The IPMVP method measures the energy consumed during a reference period, and the energy consumed during a follow-up period after the implementation of improved energy efficiency actions.

The calculation is as follows :

Savings (the amount of energy measured in kWh) = (Energy of the reference period ± adjustments) – Energy monitoring period

The adjustment will simply be to calculate the value of each “point” of the adjusted reference curve.

METHODOLOGICAL OPTIONS IPMVP

The IPMVP provides a choice of four options to adapt to different situations encountered in the field :

 

  • Option A

Isolated perimeter : the system which is the subject of the EPA is isolated ; key variables are measured and other variables are estimated, including the effective use of the system.

  • Option B

Isolated perimeter : the system which is the subject of EPA is isolated, but this time all variables are measured.

  • Option C

Global scope : global consumption of the building is measured continuously.

  • Option D

Isolated or global scope : the reference situation was determined using a computer simulation , calibrated by measured data .

 

Plan Measurement and Verification consistent with IPMVP must meet 13 points:

1 . Describe the improvement of Energy Performance Shares.

2 . Identify and justify the choice of a methodological option (A, B, C, or D) in detail and evaluate the consequences in terms of interactions.

3 . Document the baseline and collect meaningful data.

4 . Identify the monitoring period.

5 . Set the adjustment conditions (Equation characteristic curve consumption and variables) demonstrate their relevance to the reference period .

6 . Specify the method for data analysis.

7 . Specify the methods used to value financial savings.

8 . Specify the instrumentation used and operation / maintenance.

9 . Assign responsibilities of M & V for the follow-up period.

10 . Specify the expected results with respect to accuracy.

11 . Set the budget associated with operations of M &V; identify resources budget.

12 . Describe report patterns and structures for the monitoring period.

13 . Enter quality insurance procedures followed in the M & V

IPMVP protocol

International Performance Measurement & Verification Protocol

The IPMVP is a protocol supported by EVO (Efficiency Valuation Organization), a global community that works for the development and promotion of the use of standardized protocols for the management of energy consumption.

This is the Measurement and Verification (M & V) protocol of energy efficiency as used in an international context. It incorporates the important elements of its counterpart: ASHRAE 14, 2002, while simplifying practice.

It is auditable and enforceable.
